Machine Description

The purpose of a metal lathe is to face, turn, knurl, thread, bore, or cut tapers in a metal workpiece with perfect accuracy.

During typical operations, the lathe spindle rotates the workpiece at various speeds against a fixed cutting tool that is positioned at a particular angle for the desired type of cut.

The cutting tool is mounted on a tool post, which is positioned by three different slides that each move in different directions.

Opposite of the headstock and spindle is a support device called a tailstock. The tailstock can be slid along the lathe bed and locked in place to firmly support the end of a workpiece.

Model G0709 (Mfg. Since 5/11)

Additional Safety for Metal Lathes

Never attempt to slow or stop the lathe spindle with

SPEED RATES. Operating the lathe at the wrong speed can cause nearby parts to break or the workpiece to come loose, which will result in dangerous projectiles that could cause severe impact injuries. Large or non-concentric workpieces must be turned at slow speeds. Always use the appropriate feed and speed rates.

CHUCK KEY SAFETY. A chuck key left in the chuck can become a deadly projectile when the spindle is started. Always remove the chuck key after using it. Develop a habit of not taking your hand off of a chuck key unless it is away from the machine.

SAFE CLEARANCES. Workpieces that crash into other components on the lathe may throw dangerous projectiles in all directions, leading to impact injury and damaged equipment. Before starting the spindle, make sure the workpiece has adequate clearance by hand-rotating it through its entire range of motion. Also, check the tool and tool post clearance, chuck clearance, and saddle clearance.

LONG STOCK SAFETY. Long stock can whip violently if not properly supported, causing serious impact injury and damage to the lathe. Reduce this risk by supporting any stock that extends from the chuck/headstock more than three times its own diameter. Always turn long stock at slow speeds.

SECURING WORKPIECE. An improperly secured workpiece can fly off the lathe spindle with deadly force, which can result in a severe impact injury. Make sure the workpiece is properly secured in the chuck or faceplate before starting the lathe.

CHUCKS. Chucks are very heavy and difficult to grasp, which can lead to crushed fingers or hands if mishandled. Get assistance when handling chucks to reduce this risk. Protect your hands and the precision-ground ways by using a chuck cradle or piece of plywood over the ways of the lathe when servicing chucks. Use lifting devices when necessary.

CLEARING CHIPS. Metal chips can easily cut bare skin—even through a piece of cloth. Avoid clearing chips by hand or with a rag. Use a brush or vacuum to clear metal chips.

STOPPING SPINDLE BY HAND. Stopping the spindle by putting your hand on the workpiece or chuck creates an extreme risk of entanglement, impact, crushing, friction, or cutting hazards.

your hand. Allow the spindle to come to a stop on its own or use the brake.

CRASHES. Aggressively driving the cutting tool or other lathe components into the chuck may cause an explosion of metal fragments, which can result in severe impact injuries and major damage to the lathe. Reduce this risk by releasing automatic feeds after use, not leaving lathe unattended, and checking clearances before starting the lathe. Make sure no part of the tool, tool holder, compound rest, cross slide, or carriage will contact the chuck during operation.

COOLANT SAFETY. Coolant is a very poisonous biohazard that can cause personal injury from skin contact alone. Incorrectly positioned coolant nozzles can splash on the operator or the floor, resulting in an exposure or slipping hazard. To decrease your risk, change coolant regularly and position the nozzle where it will not splash or end up on the floor.

TOOL SELECTION. Cutting with an incorrect or dull tool increases the risk of accidental injury due to the extra force required for the operation, which increases the risk of breaking or dislodging components that can cause small shards of metal to become dangerous projectiles. Always select the right cutter for the job and make sure it is sharp. A correct, sharp tool decreases strain and provides a better finish.

Model G0709 (Mfg. Since 5/11)

Additional Chuck Safety

ENTANGLEMENT. Entanglement with a rotat-

ing chuck can lead to death, amputation, broken bones, or other serious injury. Never attempt to slow or stop the lathe chuck by hand, and always roll up long sleeves, tie back long hair, and remove any jewelry or loose apparel BEFORE operating.

CHUCK SPEED RATING. Excessive spindle speeds greatly increase the risk of the workpiece or chuck being thrown from the machine with deadly force. Never use spindle speeds faster than the chuck RPM rating or the safe limits of your workpiece.

USING CORRECT EQUIPMENT. Many workpieces can only be safely turned in a lathe if additional support equipment, such as a tailstock or steady/ follow rest, is used. If the operation is too hazardous to be completed with the lathe or existing equipment, the operator must have enough experience to know when to use a different machine or find a safer way.

TRAINED OPERATORS ONLY. Using a chuck incorrectly can result in workpieces coming loose at high speeds and striking the operator or bystanders with deadly force. To reduce the risk of this hazard, read and understand this document and seek additional training from an experienced chuck user before using a chuck.

CHUCK CAPACITY. Avoid exceeding the capacity of the chuck by clamping an oversized workpiece. If the workpiece is too large to safely clamp with the chuck, use a faceplate or a larger chuck if possible. Otherwise, the workpiece could be thrown from the lathe during operation, resulting in serious impact injury or death.

CLAMPING FORCE. Inadequate clamping force can lead to the workpiece being thrown from the chuck and striking the operator or bystanders. Maximum clamping force is achieved when the chuck is properly maintained and lubricated, all jaws are fully engaged with the workpiece, and the maximum chuck clamping diameter is not exceeded.

PROPER MAINTENANCE. All chucks must be properly maintained and lubricated to achieve maximum clamping force and withstand the rigors of centrifugal force. To reduce the risk of a thrown workpiece, follow all maintenance intervals and instructions in this document.

DISCONNECT POWER. Serious entanglement or impact injuries could occur if the lathe is started while you are adjusting, servicing, or installing the chuck. Always disconnect the lathe from power before performing these procedures.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements:

For your own safety and protection of

Note: The circuit requirements listed in this manual apply to a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following requirements:

Grounding Instructions

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

Serious injury could occur if you connect

The power cord and plug specified under “Circuit Requirements for 220V” has an equipment-grounding wire and a grounding prong. The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances (see figure below).

The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean.

Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.

There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufacturer’s instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

Site Considerations

Weight Load

Physical Environment

Place this machine near an existing power source.

Shadows, glare, or strobe effects that may distract

Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

See below for required space allocation.

Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.

The physical environment where the machine is operated is important for safe operation and longevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device, if required.

Lighting

Lighting around the machine must be adequate enough that operations can be performed safely.

or impede the operator must be eliminated.

Lifting & Moving

Anchoring the machine to the floor prevents it from tipping or shifting and reduces any vibration that may occur during operation, resulting in a machine runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

You must use power lifting equipment and assistance to lift and move this machine. Inspect all lifting equipment to make sure it is in working order and rated for the load before attempting to lift. Ignoring this warning may lead to serious personal injury or death.

Anchoring to Floor

Anchoring to Concrete Floors

This lathe has a hole built into each end of the stand (see Figure 8) that is designed to accept a sturdy 1" diameter lifting bar. Each bar must extend far enough from the stand so that chains or lifting straps can be looped or connected to all four corners and the lathe can be lifted.

Leveling

For accurate turning results and to prevent warping the cast iron bed and ways, the lathe bedways MUST be leveled from sideto-side and from front-to-back on both ends.

Re-check the bedways 24 hours after installation, two weeks after that, and then annually to make sure they remain level.

Leveling machinery helps precision components, such as bedways, remain straight and ﬂat during the lifespan of the machine. Components on a machine that is not level may slowly twist due to the dynamic loads placed on the machine during operation.

For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard newspaper) is placed under one end of the level.

Lubricating Lathe

It is critical that there is oil in the headstock, quick change gearbox, and the apron gearbox before proceeding with the test run. Refer to the Lubrication instructions on Page 56 for more details on which type and how much oil to use in each gearbox.

GEARBOXES MUST

BE FILLED WITH OIL!

NO OIL SHIPPED WITH

Model G0709 (Mfg. Since 5/11)

Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use an electrician or qualified personnel to ensure a safe power connection.

Once all preparation steps previously described in this manual have been completed, the machine can be connected to the power source. In order to be connected to the power source, a circuit must be installed/prepared that meets the requirements of the lathe, and a power connection method must be established for that circuit.

Using an incorrectly sized cord causes machine electrical components and the cord to become very hot, which can lead to component failure or result in fire. For best results, use the shortest length of cord possible, and never use a smaller cord gauge than the specified minimum.

Test Run

Once assembly is complete, test run the machine to make sure it runs properly and is ready for regular operation. The test run consists of verifying the following: 1) The motor powers up and runs correctly and 2) the stop button safety feature works correctly.

If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review Troubleshooting on Page 59.

If you cannot find a remedy, contact our Tech Support at (570) 546-9663 for assistance.

To begin the test run:

1. Make sure you understand the safety instruc-

tions at the beginning of the manual and that all previous setup sections have been completed.

2. Make sure the lathe is lubricated and the oil levels are at the full mark. Refer to

Maintenance on Page 53 for details.

3. Make sure the chuck is correctly secured to the spindle. Refer to Chuck and Faceplate Mounting on Page for detailed installation

instructions.

Spindle Break-In

Before subjecting the spindle to operational loads, it is essential to complete the break-in process. This helps ensure maximum life of spindle bearings and other precision components by thoroughly lubricating them before placing them under load.

After spindle break-in is complete, we recommend changing headstock and gearbox oil to remove any metal particles or debris that are present from the assembly and break-in process.

The break-in must be performed in succession with the manual, as the steps in that procedure prepare the lathe controls for the break-in process.

Test Run procedure described in this

DO NOT perform this procedure independently of the Test Run section. The lathe could be seriously damaged if the controls are set differently than instructed in that section.

Recommended

Adjustments

For your convenience, the adjustments listed below have been performed at the factory.

However, because of the many variables involved with shipping, we recommend that you at least verify the following adjustments to ensure the best possible results from your new machine.

Step-by-step instructions for these adjustments can be found in the SERVICE section starting on

Page 59.

Factory adjustments that should be verified:

• Verify Three-Jaw Chuck Registration in

Chuck and Faceplate Removal/Installation

(Page 27)

• Camlock Stud Installation (Page 29)

• Gib Adjustments (Page 61)

• Tailstock Alignment (Page 36)

To perform the spindle break-in:

1. Successfully complete the Test Run proce- dure beginning on Page 19.

2. Disengage the half-nut lever and the feed

selection lever.

3. Run the spindle at 70 RPM for 10 minutes each in direction (first forward and then reverse).

4. Repeat running the lathe in this manner through the rest of the spindle speeds, progressively increasing in RPM.

5. Press the stop button and DISCONNECT THE LATHE FROM POWER! The lathe is broken in.

Just because the power light is OFF, do not assume that the lathe is safe for electrical work, general adjustments, or workpiece changes. You must always disconnect the lathe from power before attempting any of these tasks.

Power Button

Prevents accidental start up. Every time the stop button is pressed in and then reset, the power button must be pressed. If there has been a power outage while the lathe was operating, when power is resumed, the power button must be pressed to reactivate the power to the control panel. If the foot brake is pressed, a limit switch will cut power

to the motor immediately.

Chuck & Faceplate

Removal/Installation

This lathe is shipped with a 3-jaw chuck installed, but also includes a 4-jaw chuck and 12" faceplate. The chucks and faceplate mount to the spindle with a D1-5 camlock system, which uses a key to loosen and tighten camlocks for removal or installation (see Figure 18).

Chuck & Faceplate Removal

1. DISCONNECT LATHE FROM POWER!

2. Lay a chuck cradle (see Figure 20) or a layer

of plywood over the bedways to protect the precision ground surfaces from damage and to prevent fingers from being pinched.

Figure 20. Simple chuck cradle made of scrap

lumber.

Figure 18. Chuck key positioned to remove a

typical camlock mounted chuck.

Before the 4-jaw chuck and faceplate can be installed on the spindle, their respective cam studs must be installed and adjusted.

To maintain consistent removal and installation of the chucks and faceplate, each should have a timing mark that can be lined up with a matching one on the spindle, so it will be installed in the same position every time (see Figure 19). Before removing the 3-jaw chuck, verify that a timing mark exists. If a mark cannot be found, stamp your own on both the chuck and spindle.

Timing

Marks

PINCH HAZARD! Protect your hands and the precision ground bedways with plywood or a chuck cradle when removing the lathe chuck! The heavy weight of a falling chuck can cause serious injury.

3. Loosen the cam-locks by turning the key

counterclockwise approximately one-third of a turn until the mark on the cam-lock aligns with the single mark on the spindle nose in Figure 21. If the cam-lock stud does not freely release from the cam-lock, wiggle the cam-lock until the cam-lock stud releases.

Note: These cam-locks may be very tight. A

breaker bar may be used to add leverage.

let, lightly tap around the outer circumference of the chuck body to break the chuck free from the cam-locks and from the spindle nose taper.

CAUTION: The chuck may come off at this

point, so it is important you are ready to support its weight.

Large chucks are very heavy. Always get assistance when removing or installing large chucks to prevent personal injury or damage to the chuck or lathe.

2. Place a piece of plywood across the lathe

ways just under the chuck, and use a chuck cradle if desired.

3. Make sure the chuck taper and spindle taper mating surfaces are perfectly clean.

4. Inspect and make sure that all camlock studs are undamaged, are clean and lightly oiled, and that the camlock stud cap screws are in place and snug.

—If the camlock studs have not yet been

installed in the chuck or faceplate, complete the Camlock Stud Installation on the next page.

NOTICE

Never install a chuck or faceplate without having the camlock cap screws in place or fully tightened. If you ignore this notice, once installed the chuck may never be able to be removed since the camlock studs will turn with the camlocks and never release.

5. Use a rocking motion to carefully remove the

chuck from the spindle (see Figure 22).

—If the chuck does not immediately come off,

rotate the spindle approximately 60˚ and tap again. Make sure all the marks on the cams and spindle are in proper alignment.

Three-Jaw Chuck

To use the 3-jaw chuck:

1. DISCONNECT LATHE FROM POWER!

This section outlines basic operation safety related to using the 3-jaw chuck included with your lathe. Use knowledge of safety and common sense when applying the steps on how to use this chuck. If you have any questions, feel free to contact our Technical Support Department.

The 3-jaw chuck shipped with this late has a twopiece reversible jaw design. An internal scrollgear, moves all jaws in unison when adjusted. This chuck will hold cylindrical parts on-center with the axis of spindle rotation, and can be spun at high speeds if the workpiece is properly clamped and is balanced. If a workpiece must be held from the inside, rotate all three of the two-piece jaws 180° so the orientation of all jaws match. Otherwise

the chuck will spin out of balance an create an extreme thrown workpiece hazard!

Reversing Jaw Positions & Clamping a Workpiece

Figure 25 shows a typical example of clamping

options available with a 3-jaw chuck. The chuck included with this lathe has reversible jaws, which means the lower jaw or master jaw do not need to be removed to reverse the jaw position. Instead, the top jaw is fastened to the master jaw with cap screws that when removed allow for top jaw reversal. It is a good practice to keep the top jaws matched with their original master jaw, to ensure maximum quality of alignment and exact fit.

2. Remove the cap screws that retain the top portion of one of the jaws (see Figure 26), and remove the jaw.

Figure 26. Reversing the chuck jaws.

3. Making sure the longer cap screw remains in the thicker part of the jaw, rotate the jaw 180˚ and re-install it to the lower jaw (see Figure

26).

4. Repeat Steps 2–3 on the remaining jaws

Always securely tighten jaws and remove all tools from the lathe before starting spindle! Thrown objects from a lathe can cause serious injury or death to the operator and to bystanders.

Model G0709 (Mfg. Since 5/11)

Four-Jaw Chuck

To use the 4-jaw chuck:

1. DISCONNECT LATHE FROM POWER!

This section outlines basic operation safety related to using the 4-jaw chuck included with your lathe. Use knowledge of safety and common sense when applying the steps on how to use this chuck. If you have any questions, feel free to contact our Technical Support Department.

Select this chuck for low-speed lathe operations only. The 4-Jaw chuck uses independently adjustable jaws, meaning each is adjusted by an individual worm gear. Non-cylindrical parts can be held and brought into the spindle centerline for facing or boring. The other benefit is that the majority of a workpieces can be positioned out of the spindle rotation axis if a bore or step needs to be cut into a workpiece on an outlying edge.

For the best grip possible on odd-shaped workpieces, one or more jaws can also be rotated

180° to grab more surface area for clamping.

If all four jaws cannot be used to hold the workpiece, you must use the faceplate for improved clamping options. Otherwise, a severe out-of-balance condition will be created. If spun even at an average speed, this chuck will almost always be out of balance, and the machinist and bystanders will be at risk of being hit with a thrown workpiece. Being hit by an ejected workpiece can be fatal.

2. Install a center in the tailstock.

3. Open each jaw with the chuck wrench and

place the workpiece flat against the chuck face.

4. Support the workpiece and slide the tailstock forward so the tip of the dead center presses against the workpiece. Next, lock the tailstock in position. For more information, refer to the tailstock controls on Page 67 and Centers on

Page 33.

5. Turn the tailstock quill so the dead center

applies enough pressure to the center point of your workpiece to hold it in place (see Figure 28), then lock the tailstock quill.

6. Turn each jaw until it just makes contact with the workpiece.

7. Tighten each jaw in small increments. After adjusting the first jaw, continue tightening in opposing sequence (see Figure 28). Check frequently to make sure the required point on the workpiece has not wandered away from the spindle centerline due to applying too much pressure to a single jaw.

-31-

8. After the workpiece is held in place, back the tailstock away and rotate the chuck by hand. The center point will move if the workpiece is out of center (see Figure 29).

Figure 29. Properly held workpiece for low

speed offset boring or machining.

9. Make fine adjustments by slightly loosening one jaw and tightening the opposing jaw until the workpiece is held securely and precisely aligned with the spindle centerline.

Faceplate

This section outlines basic operation safety related to using the faceplate included with your lathe. Use knowledge of safety and common sense when applying the steps on how to use this faceplate. If you have any questions, feel free to contact our Technical Support Department.

The faceplate is cast-iron and has multiple slots for T-bolts that hold clamping hardware. If you suspect that any of the chuck or jaw combinations may not hold a workpiece safely, remove the chuck and install the faceplate as outlined for special clamping options.

However, just as with the 4-Jaw chuck, not all workpieces can be safely held. Holding a workpiece off center or holding an irregular-

shaped workpiece will cause the entire assembly to rotate out of balance. If spun at any speed higher than low, the workpiece can eject hitting the lathe operator or bystanders causing a severe or fatal injury.

Figure 30 shows an example of a workpiece being improperly held with the 4-jaw chuck. One jaw of the chuck interfered with the workpiece edge, and removing the jaw creates an extreme workpiece ejection hazard. The workpiece holding solution shown in Figure 30 is to use the faceplate with a minimum of three clamps that are spaced as equally apart as possible for full support.

3. Place the workpiece against the faceplate and turn the tailstock quill so the point of the dead center touches and applies enough pressure to hold the workpiece in place.

4. Lock the quill when sufficient pressure is applied to hold the workpiece. Additional support may be needed, depending on the workpiece.

5. Clamp the workpiece at a minimum of three locations that are as close to being evenly spaced apart as possible as shown in Figure

31.

The Model G0709 lathe is supplied with two MT#3 dead centers, an MT#3 live center, and a MT#5– MT#3 adapter sleeve (see Figure 32) to adapt the centers into spindle bore. When installing centers verify that all mating surfaces are clean and free of nicks and burrs.

Tip: Hand-held tapered bore wipers make this task very time efficient, and offer consistently clean bores.

7. Slide the tailstock away from the workpiece and install the required tailstock tooling for drilling or boring, or position the tool bit for facing.

Model G0709 (Mfg. Since 5/11)

Solid Dead Center

Dead centers are typically used in low speed turning operations to increase rigidity for close tolerances. The solid dead center is installed at the spindle end of the lathe because the workpiece, center, and spindle all turn together by the use of a lathe dog. One end of the lathe dog is clamped to the workpiece, and the other end the tail, is inserted into a faceplate slot shown in Figure 33).

Tip: If the tail is too large for a slot, install the 3-jaw chuck, open the jaws so the workpiece can be supported by the center and the tail of the dog can rest against a jaw.

Carbide-Tipped Dead Center

When the workpiece is supported at the tailstock end of the lathe, the workpiece will spin on the tip of the fixed center. To eliminate the tip of the center from wearing out at this point of contact, the carbide-tipped center is used. Nevertheless, during turning operations this tip must still be lubricated vigilantly, or the workpiece will wear, resulting in increased end play and poor turning results. Typically, when using centers, the tailstock quill should be locked and protrude at least more than 3".

⁄2 ", but not

Live Center

If the workpiece must be spun at higher speeds, the live center is inserted into the tailstock (see Figure 34). Unlike a dead center, the tip of the live center is supported with precision bearings that allow it to support and spin with the workpiece. As a result, virtually no wear occurs, and the workpiece can be turned with less concern about developing end play from tip wear. However, when using live centers, accuracy can suffer as a result of having bearings support the end of the workpiece.

3. Position the tailstock so the center presses against the workpiece, then lock the tailstock in place.

4. Preload the quill into the workpiece. The force against the workpiece will fully seat the tapered center.

5. Lock the quill into place. However, keep in mind that the quill may need to be adjusted during operation to remove any play that develops between the center and the workpiece.

To install a center into the tailstock:

Quill Lock Lever

The quill lock lever (see Figure 36) secures the quill in its current position. When drilling, or when tapping operations need to be done deep into a part, the quill can also be stabilized by slightly applying the lever to add drag and preload to the quill.

By offsetting the tailstock, the dead center can hold a workpiece at a particular away from the spindle centerline so tapers and pipe threads can be cut. For a quick visual tool in keeping track of tailstock movement, an offset scale (see Figure

37) with arbitrary increments is located at the rear

of the tailstock. However, to achieve exact taper angles, or to adjust the tailstock back into the spindle centerline, angle gauges and a test indicator must be used.

To offset the tailstock:

1. Loosen the tailstock lock lever.

2. Using a 4mm hex wrench, loosen one of the

front or rear adjustment screws shown in Figure 37.

Tailstock Lock Lever

When clamped in place, the forces draw a tailstock down into alignment with the spindle centerline. This distance is usually a few thousandths of an inch. When a tailstock lock lever is tightened by hand, the clamping pressure and tailstock alignment can be inconsistent. To eliminate this situation, a inserted into the lock lever drive hub (see Figure

Aligning Tailstock

The tailstock alignment was set at the factory with the headstock. However, we recommend that you take the time to ensure that the tailstock is aligned to your own desired tolerances.

When clamped in place, a tailstock experiences compression that draws its centerline downward into alignment with the spindle centerline. This distance is usually a few thousandths of an inch. When a tailstock lock lever is used by feel, or when used by different machinists, this alignment can be inconsistent.

To eliminate this variable, a wrench can be inserted into the lock lever drive hub. The tailstock can then be clamped in place at a pre-determined torque setting. All operators can then rely on the same amount of draw-down alignment that is based on the same torque setting.

3. Place the live center in your tailstock.

4. Attach a lathe dog at the spindle end to the

bar stock from Step 1, and mount it between the centers as shown in Figure 39.

Figure 39. Bar stock mounted between centers.

To align the tailstock:

1. Center drill a 6'' long piece of bar stock on both ends. Set it aside for use in Step 4.

2. Make a dead center by turning a shoulder

to make a shank. Flip the piece over in the chuck and turn a 60° point (see Figure 38). As long as it remains in the chuck, the point of your center will be accurate to the spindle axis.

Note: Keep in mind that the point will have

to be refinished whenever it is removed and returned to the chuck.

5. Turn approximately 0.010" off the diameter.

6. Mount a dial indicator so that the plunger is

on the tailstock quill (see Figure 40).

Looking down from above.

Figure 40. Adjusting for headstock end taper.

7. Measure the stock with a micrometer. If

the stock is wider at the tailstock end, the tailstock needs to be moved toward the front of the lathe the amount of the taper (see Figure 40).

— If the stock is thinner at the tailstock end,

the tailstock needs to be moved toward the rear of the lathe by at least the amount of the taper (see Figure 41).

Drilling with

Tailstock

The tailstock quill has an MT#3 taper with a lock slot at the bottom to accept tang-style tooling. If the tooling will experience high torque loads during operation, it is critical to use tanged-style to prevent the drill bit or arbor from spinning and galling the quill bore. Restoring a galled bore and taper can be time consuming or require quill replacement.

However, tooling without tang-styled arbors can be used if they meet the following criteria.

Looking down from above.

Figure 41. Adjusting for tailstock end taper.

NOTICE

DO NOT forget to lock the tailstock to the ways after each adjustment.

8. Loosen the tailstock lock lever and adjust the

tailstock offset by the amount of the taper.

9. Turn another 0.010'' off of the stock and check for any taper.

10. Repeat as necessary until the desired level of accuracy is achieved.

• Very little torque loads will be applied to the tooling such as with centers.

• The tap or drill bit is not larger than diameter.

• The end of the arbor is solid, or has a screw threaded into the hole making the end of the arbor solid. Installing an arbor with a solid end is important to avoid the arbor from becoming stuck in the quill. Some arbors equipped with the hole are too short to be exposed in the drift slot for removal, and the tailstock pin has no surface to push against when using the handwheel to remove the arbor. As a result, the arbor becomes stuck requiring the quill to be removed and the arbor driven out with a punch.

Tip: When drilling or when tapping operations need to be done deep into a part, the quill can also be stabilized by slightly applying the lever to add drag and preload to the quill.

To install a tanged drill or chuck:

1. Lock the tailstock in position, then unlock the

quill.

2. Use the quill feed handwheel to extend the quill about 1" out of the tailstock.

3. Insert an MT#3 chuck arbor or drill bit into the quill just until the tang drops into the slot and the tapers just touch.

Tip: For maximum locking of large diameter drill

bits, push and seat the drill bit into the quill with a clockwise rotation as to load the tang against its slot.

4. Tap the end of the tooling or drill bit with a wooden block or mallet to seat the tool.

To remove a tapered drill or chuck:

1. Turn the handwheel counterclockwise until

the arbor or drill bit is pushed out from the tailstock taper.

—If the tool is stuck in the bore and cannot

be removed by turning the handwheel with moderate force, extend the quill to expose the drift key slot, and use any standard drift key to remove the stuck tooling.

5. Lock the quill.

NOTICE

Running the pump without adequate cutting fluid in the reservoir may permanently damage it. This type of damage is not covered by the warranty.

The steady rest is clamped to the ways and supports the workpiece with three fingers at a single point between the chuck and the tailstock.

The follow rest is bolted to the carriage and travels with it during turning or threading operations. Two fingers support the workpiece while the tool tip acts as the third support during cutting.

Both the steady rest and the follow rest use ball bearing-tipped fingers instead of solid brass tips. The fingers have a guide slot where the tip of an adjustable set screw rides. These screws are held in place with jam nuts. The set screws must be tightened inward far enough so they bottom slightly, providing preload and keeping the finger in alignment with only slight rocking in its bore.

When using either of these rests, keep in mind that most machining operations must be done at low spindle speeds to prevent a workpiece ejection hazard.

Always use high quality cutting fluid and follow the manufacturer's instructions for diluting. Frequently check the cutting fluid condition and change it promptly when it becomes overly dirty or rancid. Refer to Cutting Fluid on Page 58 for changing the fluid or filling for the first time.

To use the cutting fluid system:

1. Make sure the cutting fluid tank is properly

serviced and filled.

2. Position the cutting fluid nozzle as desired for your operation.

3. Use the control panel switch to turn the cutting fluid pump ON.

4. Adjust the flow of cutting fluid by using the valve lever at the base of the nozzle hose.

Spider

Spindle Speed

Your lathe is equipped with a set of outboard spindle supports known as a "spider," shown in Figure 46.

Spider

Figure 46. Spider assembly located on the out-

board spindle.

Use the spider when a long workpiece has the potential to wobble or vibrate when it extends through the outboard side of the spindle.

Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life.

To set the spindle speed for your operation, you will need to: (1) Determine the best spindle speed for the cutting task, and (2) configure the lathe controls to produce the required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operations, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown in Figure 47.

*Recommended

Cutting Speed (FPM) x 12

Dia. of Cut (in inches) x 3.14

Spindle

Speed (RPM)

*Double if using carbide cutting tool

The tips of the spider screws have brass wear pads that hold the workpiece without causing indents or marring.

When the spider screws are installed, and regardless if they are used to hold a workpiece or not, always lock each spider screw in place by tightening the jam nuts. If a workpiece is installed, merely tightening the spider screws against the workpiece and leaving the jam nuts loose is not safe. Spider screws that loosen during operation can crash into the lathe end cover.

To avoid creating an entanglement hazard, remove the spider screws when not in use, and always disconnect the lathe from power when installing, removing, or adjusting the spider screws. Ignoring this warning can lead to personal injury or machine damage.

Figure 47. Spindle speed formula for lathes.

Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface.

A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life.

The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.

Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. All of these sources will help you take into account all the applicable variables in order to determine the best spindle speed for the operation.

Changing Spindle Speed

To change the spindle speed:

This lathe is equipped with two levers shown in Figure 48 that are used to achieve eight spindle speeds. Never move either lever while the

spindle is rotating, or gear clash and tooth fracture may occur. When the lathe is stopped,

if the levers do not fully engage, the spindle must be slightly rotated by hand.

Cross Slide Handwheel

Moves the cross slide in or out perpendicular to carriage travel with a 10-TPI leadscrew. Movement is in increments of 0.001", where a total revolution of 0.100" equals 0.200" of cross slide movement. This micrometer scale is a "Standard Dial" that has a ratio of 1:2. For example, if the hand wheel is rotated clockwise 0.015" during a turning operation, 0.030" will be removed from the overall diameter of the workpiece, as the outside diameter is measured with a caliper.

Compound Slide Handwheel

Moves the compound and cutting tool relative to the workpiece at various angles with fine-depth control in inch calibrations. One full rotation equals 0.100" of compound movement or equates to a ratio of 1:1. The scale is broken down in increments of 0.001".

Sometimes it is necessary to rock the carriage handwheel or the cross feed handwheel to assist in fully engaging the chosen feed gears. To prevent inadvertent apron damage, the apron is equipped with an internal lockout system that prevents the feed selection lever and half-nut levers from being engaged at the same time. However, before engaging the apron for any longitudinal feed operations, make sure that the carriage lock is loose and the carriage is allowed to move freely, or the feed system may be damaged.

Moving the feed selection lever upwards from the central or disengaged position engages the cross slide for in-and-out facing operations.

Moving the feed selection lever downwards from the central disengaged position, engages the carriage for left-or-right longitudinal turning operations.

The speed at which the carriage travels is set with the feed speed dials (refer to Feed Settings on Page 44). The feed direction is changed by the feed direction lever on the headstock.

NOTICE

A high feed rate or threading at a high speed reduces your reaction time to disengage the apron or leadscrew to avoid a crash with the spinning chuck. When threading, making too deep of a cut can result in the half nut binding with the leadscrew causing an impaired ability to disengage the half nut to avoid a chuck crash. Pay close attention to the feed rate you have chosen and keep your foot poised over the brake pedal. Failure to fully understand this may cause the carriage to crash into the chuck.

Feed Settings

Various feed rates are achieved on this lathe by moving knobs, levers, and rearranging change gears according to the threading chart located on the headstock. All required change gears are

pre-installed on this lathe, and no external gears are required.

To set up for a power feed operation:

1. DISCONNECT LATHE FROM POWER!

2. Remove the cover on the left-hand side of the

headstock to expose the change gears.

3. Look at the lathe feed rate chart, and find the required feed rate for your turning or facing operation. In each box on the chart, two numbers are separated by a slash (see Figure

51). The top-right number is carriage feed, and the bottom-left number is cross feed. If for example, a carriage feed rate of 0.00168" is needed, the change gears and feed dials must be in the following positions FATX1.

—"F" is the first letter in the sequence and

indicates that the change gears must be rearranged in the "F" sequence as shown in Figure 52. The change gears are locat- ed on the left-hand side of the lathe, behind the headstock gear cover shown in.

—"ATX" is the second group of letters that

indicate which positions to turn the letteredfeed dials to.

—"1" is the last digit and indicates which posi-

tion to turn the numbered feed dial to.

6. Move the feed dials to the combination of FATX1, as shown in Figure 53.

Thread Settings

Regardless of the example given below, the setup procedure on this lathe is the same for metric, inch, module, or diametral pitch threads. These thread selections are indicated by a series of letters and numbers shown on the headstock threading charts. First, the change gear positions are checked and rearranged if indicated by the chart. Next, the quick change gearbox knobs and levers are moved to specific positions also indicated by the chart.

To set up for threading:

1. DISCONNECT LATHE FROM POWER!

2. Remove the cover on the left-hand side of the

headstock to expose the change gears.

3. Review the threading chart for the required thread to be cut (see Figure 54). The chart indicates that to cut a 0.75 metric thread, the change gears and feed dials must be in the following positions FBSW6.

—"F" is the first letter in the sequence and

indicates that the change gears must be rearranged in the "F" order (see Figure

55).

—"BSW" is the second group of letters that

indicate which position to turn the letteredfeed dials to.

—"6" is the last digit and indicates which

position to turn the numbered feed dial to.

4. Leaving 0.003"–0.005" backlash between gear teeth, arrange the change gears to match the order under "F" (see Figure 55).

Feed Direction Lever

When threading, the feed direction lever (see Figure 57) moves the carriage to the left toward the headstock (forward), and moves the carriage to the right toward the tailstock (reverse). The leadscrew will not turn when the feed direction lever is in the neutral position.

Figure 55. Change gear and chart relationship.

5. Rotate the spindle by hand to verify no bind-

ing exists, and re-install the gear cover.

6. Move the threading dials to the combination of FBSW6, as shown in Figure 56.

Feed Selection Lever

To prevent apron and drive system damage, the apron is equipped with an internal lockout, meaning that in order to engage the half nut for threading, this lever (see Figure 57) must be moved to the central or the disengaged position. Also keep in mind that just as with longitudinal feed operations, before any threading operation. You must first verify the carriage lock (see Figure 57) is disengaged, or the feed system may be damaged.

Half-Nut Lever

When the feed selection lever and carriage lock are disengaged, the half-nut lever (Figure 59) can be moved downward from the disengaged upper position to clamp the half nut around the leadscrew for threading operations.

Thread Chart

The thread dial chart is located on the headstock cover, as shown in Figure 60 and 61.

Engaged

Figure 59. Half nut lever.

DO NOT engage the half nut if the leadscrew will rotate over 200 RPM, or if the carriage lock is applied. Disregarding this warning may cause damage to the bearings or the leadscrew shear pin to break.

Thread Dial

When cutting inch threads and the pass has been completed, the thread dial (see Figure 60) allows the machinist to disengage the carriage from the leadscrew, and quickly return the carriage for the next pass. Based on the thread TPI being cut, and what is indicated on the thread chart, the dial indicates where the machinist must re-clamp the half nut in order to resume the same thread to avoid cross-cutting threads.

locations.

Thread Dial

When cutting metric and other types of threads, the thread dial must be disengaged from the leadscrew, and the half nut clamped to the leadscrew until the threads are complete. Otherwise the path of the same thread will be lost. All carriage returns for non-inch threads are made by backing the tool point out of the thread, and reversing spindle rotation with the spindle ON/OFF lever.

To engage the thread dial, loosen the mounting cap screw, then pivot the dial into the leadscrew so the gear teeth mesh with the leadscrew. Retighten the cap screw to hold the thread dial in place.

Find the TPI (threads per inch) that you want to cut in the left columns (under TPI), then reference the dial number in the right columns (under Scale). The dial number indicates when to engage the halfnut for a specific thread pitch as indicated by the thread dial (see Figure 60).

The following examples explain how to use the thread dial and the thread dial chart.

TPI Divisible by 8: For threading a TPI divisible by eight, use any line on the thread dial (see the example in Figure 62).

Odd Numbered TPI: For odd numbered TPI, use only the number 1 on the thread dial (see the example in Figure 64).

SECTION 6: MAINTENANCE

Always disconnect power from the machine before performing maintenance. Ignoring this warning may result in serious personal injury.

Schedule

For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.

Cleaning

Cleaning the Model G0709 is relatively easy. Disconnect the lathe before cleaning it. Remove chips as they accumulate. Vacuum excess metal chips and wipe off the remaining cutting fluid with a dry cloth when finished for the day. Chips left on the machine soaked with water-based cutting fluid will invite oxidation and gummy residue to build up around moving parts. Preventative measures like these will help keep your lathe running smoothly. Always be safe and responsible with the use and disposal of cleaning products.

Every 6–8 Hours of Running Time:

• Clean/vacuum lathe.

• Wipe down unpainted cast iron, including leadscrew, with way oil or other quality metal protectant.

• Lubricate ball oilers (Page 54).

• Check oil reservoirs (Page 56).

Each Week:

• Check cutting fluid system (Page 58). Clean tank and replace cutting fluid as necessary.

Each Month:

• Check/adjust V-belt tension (Page 70).

Every Six Months:

• Change oil in headstock, gearbox, and apron (Page 57).

Unpainted Cast Iron

Protect the unpainted cast iron surfaces on the lathe by wiping them clean after every use—this ensures moisture does not remain on bare metal surfaces.

Keep ways rust-free with regular applications of H8257—Primrose Armor Plate with Moly-D Machine and Way Oil.

Model G0709 (Mfg. Since 5/11)

-53-

Ball Oiler Lubrication

When lubricating ball oilers, we recommend using an oil gun with a rubber tip wide enough to seal against the ball oiler inlet. A good seal allows the gun to build enough hydraulic pressure to flush out contaminants and deliver oil at the end of long passages. We do not recommend using oil guns with a steel lance tip, because they do not create a seal and the narrow tip can easily dislodge the ball—resulting in contamination, insufficient lubrication, and a damaged ball oiler.

Changing Oil

The oil in the reservoirs must be changed after the first three months of operation, then twice a year after that. If the lathe is under heavy use, more frequent oil changes will be required to keep the gearboxes clean and ensure long machine life. Some lathe owners believe that by using full synthetic oils in the gearboxes is a way to extend oil change intervals. We do not recommend this practice. While synthetic oils are superior this lathe does not use a filter to remove contaminants that are generated during normal use, such as when shifting gears. Changing the oils on a frequent basis to flush out moisture and contaminants is still the best option to ensure long gearbox life.

V-Belt Tension

After initial break in, the V-belts slightly stretch and seat into the pulley. It is important to check and adjust them to compensate for this initial wear. Check the tension thereafter on a monthly basis.

Cutting Fluid System

BIOLOGICAL AND POISON HAZARD! Use the correct personal protection equipment when handling cutting fluid and by follow federal, state, and fluid manufacturer requirements to properly dispose of cutting fluid.

3. Inspect the level of cutting fluid inside the

tank. The cutting fluid should be approximately an inch below the top of the tank.

4. Using a wooden stick, check the level of the metal chips in the first chamber (see Figure

96). If the chips are then remove the chips.

First Chamber

Full Level 1" From Tank Rim

Located at the tailstock end of the lathe is an access cover where the pump and a cutting fluid tank are located. A screen in the chip drawer prevents large metal chips from entering the tank. The small metal chips wash down into the cutting fluid tank that is split into two chambers by means of a baffle. The first chamber allows the small chips to settle to the bottom, and lets clean cutting fluid overflow the baffle and enter the second chamber where the pump draws clean fluid. Inspect the tank often to verify that metal chips are not overflowing into the second chamber where, if left for a period of time, pump damage may occur.

Tip: For speedy chip removal from the tank, a metal catch basket with handles can be made to lift out the metal chip buildup in the first chamber.

Gib Adjustments

The cross-slide and compound slide on this lathe each use a long steel wedge called a gib that is positioned between the component and its dovetailed-ways. At the end of each gib is a gib screw one of which is shown in Figure 97. The screws at each end of the gib oppose one another to move and hold the gib in a forward or aft position. Depending which direction the gib is moved and held, the space between the sliding ways is increased or decreased to control the rigidity of the cross slide and compound slide.

Cross Slide Gib

Make sure the ways and leadscrew have been cleaned and re-lubricated before beginning any adjustments. Refer to Ball Oiler Lubrication on Page 54 for instructions and lubricant specifications.

To adjust the cross slide gib:

1. DISCONNECT LATHE FROM POWER!

Before adjusting gibs, consider the lathe operation that you will perform because the cross slide and compound rest leadscrew nuts may also have to be adjusted.

• For heavy turning and facing loads, tighten gibs for maximum rigidity, and loosen the leadscrew nuts for shock loading protection.

• For high-tolerance turning and facing, and light-loads, loosen the gibs to allow for small slide movements without binding or tool bit leap, and tighten the leadscrew nuts for fine handwheel control.

Most lathe operations exist between the two examples above. Finding the optimum combination for your requirements may take practice, and trial and error before you are satisfied.

NOTICE

When adjusting gibs, keep in mind that the goal of gib adjustment is to remove unnecessary sloppiness from the slide without causing binding and excessive half nut wear.

Tip: The compound and cross slide gibs have a

gib lock screw that are shown in Figures 97 –98. This screw allows the machinist to quickly tighten the locks to hold a gib and slide in a rigid position without having to tighten the gibs. When finished with the need for increased rigidity, the gibs then are quickly unloaded back to their normal state by loosening the screw.

2. Loosen the gib lock shown in Figure 97.

Front Gib Screw

The saddle gib is located on the bottom of the back edge of the slide (Figure 100). This gib is designed differently than the cross or compound slide gibs. Instead of being a wedge-shaped plate, it is a flat bar. The gib pressure is applied by four set screws. Hex nuts secure these set screws in place, so they will not loosen during operation.

Saddle Gib

The saddle is supplied with a carriage lock on the front right-hand side of the slide (see Figure 99). This bolt locks the saddle in place for increased rigidity when making face cuts. Before making adjustments to the saddle gib, make sure that this lock is loose by turning it counterclockwise one full turn.

IMPORTANT: Do not loosen the carriage lock more than a couple of turns or the components inside will come apart. Re-installing these components is difficult and time consuming.

Backlash Adjustment

Backlash is the amount of play in a leadscrew and can be felt as the free play in a handwheel when changing direction of rotation. The amount of the backlash can be viewed on the handwheel micrometer-collar.

3. Rotate the cross slide handle clockwise to feed the leadscrew nut out from under the cross slide, as shown in Figure 102.

Leadscrew Nut

When adjusting backlash, tighten the components enough to remove backlash, but not so much that the components bind the leadscrew, making it hard to turn. Overtightening will cause excessive wear to the sliding block and leadscrew.

To adjust the cross slide backlash:

1. Feed the cross slide backwards (toward the

front of the machine) until it reaches the end of its travel.

2. Remove the cap screw that secures the cross slide leadscrew nut (see Figure 101).

Half Nut Adjustment

The half-nut mechanism can be adjusted if it becomes loose from wear. The half nut is mounted in ways with a gib exerting pressure between components to reduce sloppy movement. The half-nut gib is a flat bar-type gib, similar to the saddle gib, and is tensioned with three set screws.

Figure 105. Leadscrew shear pin.

For example, the pin may shear if the carriage path is obstructed during threading, the tool bit crashes into a workpiece shoulder, the carriage lock is left applied when the half nut is engaged, or too deep of a cut is taken, causing a sudden binding of the tool and workpiece.

It is imperative to recognize, however, that the shear pin is not a foolproof way of protecting your lathe from damage if an operational mistake is made, a chuck-carriage crash occurs, or general machine overloading occurs on a regular basis.

Always have a few extra pins on hand in case of an emergency. If a replacement is not on hand, do not improvise by inserting a roll pin, cotter pin, steel dowel, or nail. Doing so will void the warranty, and can lead to a non-shearing pin, resulting in catastrophic gearbox damage.

2. Unlock the half-nut lever and disengage the gearbox so the leadscrew can be rotated by hand.

3. Rotate the drive hub, and inspect it to see if the pin is still stuck in both sides of it.

—If one half of the shear pin has fallen out

and the leadscrew shaft can be seen through the pin hole, rotate the leadscrew and until the end of the inner sheared pin can be seen. Next, insert the punch into the hole and tap the pin out through the other side.

—If the shear pin halves are still stuck in both

sides of the drive hub, center punch one of pins and drill an mately screw into the hole until the screw begins to thread into the brass. Using pliers, pull the pin from the hole, and drive the rest of the pin out as outlined above.

4. Align the holes in the drive hub with the hole in the leadscrew, and tap the new shear pin into position until it is flush.

Tip: For easy shear pin replacement in the

future, use the center punch or a scribe and mark the end of the drive hub and the side of the leadscrew with a timing mark to indicate where true hole alignment is located. Next, scribe a line on the leadscrew just where it enters the drive hub, this line will indicate correct depth of leadscrew. Should the pin ever shear again, line-up the marks, and drive out the pin pieces, and tap in the new pin.

The clutch may slip if the path for the carriage or the cross feed is obstructed during turning or facing operations, the tool bit crashes into a workpiece shoulder, the carriage lock is left applied when the feed selection lever is engaged, or if too deep of a cut is taken, causing a sudden binding of the tool and workpiece.

It is imperative to recognize however, the clutch is not a foolproof way of protecting your lathe from damage if an operational mistake is made, a chuck-carriage crash occurs, or general machine overloading occur on a regular basis.

Never completely tighten the feed clutch spanner nut past its normal setting outlined in this procedure in an attempt to completely eliminate clutch slip. Doing so will void the warranty, and can lead to a non-slipping clutch, resulting in catastrophic gearbox damage.

—If the clutch was dissembled or replaced

for any reason, use the spanner wrench to tighten the spanner nut until a noticeable increase in torque is felt in the wrench. The increase will be quite abrupt. At this point, stop and install the lock screws.

NOTICE

For the next step, DO NOT strike the wooden block with excessive force. If you do, you can cause the tapered roller bearings to indent the mating races. If this damage occurs, one or more spindle bearings will have to be replaced, as this damage will generate vibration at higher spindle speeds.

6. Since the spindle bearings may unseat eas-

ily without great force, hold a wood block against the outboard end of the spindle, and tap the block a few times with a three or four pound hammer (see Figure 110). Your goal is to slide the spindle forward just enough to introduce spindle end-play that can be heard or felt by hand.

Figure 110. Un-seating spindle bearings to intro-

duce spindle end-play.

7. Place a dial indicator on the cross slide and move the carriage toward the headstock until the contact point of the indicator touches the spindle face (see Figure 111).

Figure 111. Dial indicator setup.

8. Move the carriage an additional 0.100" toward

the headstock, and zero the dial indicator.

-68-

Model G0709 (Mfg. Since 5/11)

9. Insert the chuck wrench into a cam socket to prevent the spindle from turning, then tighten the inner spanner nut until the dial indicator needle just stops moving (see Figure 112).

While tightening the spanner nuts, rock the

spindle back and forth slightly with the cam key to make sure the spindle tapered roller bearings seat properly in their races.

When the dial indicator needle stops mov-

ing, there will be zero spindle end-play and no bearing preload. It is essential that you find this point without tightening the spanner nut too much and inadvertently pre-load the spindle bearings.

11. Without allowing the inner spanner nut, to tighten any farther, tighten the outer spanner nut against the inner nut.

Do not overtighten the outer spanner nut

because additional preload can force the bearings even tighter against the races in the headstock and cause the headstock to compress or crack, or the bearing may quickly fail.

To confirm that the bearings are correctly preloaded:

1. Re-attach all removed lathe components and

prepare it for operation.

2. Install the chuck and tighten the jaws.

3. Set the spindle speed to its highest setting.

4. Connect the lathe to power and turn the lathe

spindle ON.

Figure 112. Adjusting spindle bearings.

Since it takes great effort to turn the inner

spanner nut, you may find it difficult to know if you have gone past the zero end-play point or not. It is easiest to have someone watch the dial while you tighten the inner spanner nut. If you think you may have gone past the zero end-play point, take the time to unload the bearings as described earlier, then re-tighten the inner spanner nut until it has reached the zero end play position.

10. Tighten the spanner nut an additional

⁄16-

turn.

5. Periodically shutting down the lathe a few times and checking temperature, let the lathe run for 20 minutes.

6. Turn the spindle OFF, disconnect lathe from power, and check the temperature of the spindle.

—If the spindle nose is slightly warm to the

touch, you have correct bearing preload.

—If the spindle nose is hotter than you

can comfortably keep your hand on, the preload is too tight and you must repeat the bearing preload adjustment procedure. When repeating the procedure, rotate the inner spanner nut a little less during Step 10 in the preceding instructions.

Gap Insert Removal

& Installation

This lathe is equipped with a removable gap insert that will allow for turning large diameter workpieces. The gap was seated, pre-loaded, and then ground for precise mating and alignment at the factory. Removing the gap can cause the lathe insert to slightly spring out of shape. When re-installed, there is no guarantee that original alignment and flush mating will be the same. For this reason, removing the gap is considered a permanent alteration to the lathe, even if it is later re-installed.

5. Tap the outside of the gap piece with a dead blow hammer to loosen it, and, with the help of another person, remove the gap piece.

To re-install the gap:

5. Install and lightly snug the four cap screws

in an order that will draw the gap closer into alignment. Using blocks of wood and clamps to get mating surfaces into alignment can also be helpful.

6. When alignment and flush mating is acceptable, tighten the four cap screws in a pattern that will maintain or improve the alignment.

1. Clean all mating surfaces completely with mineral spirits and inspect and remove any burrs. ALL MATING SURFACES MUST BE ABSOLUTELY CLEAN!

2. Lightly oil a lint-free cloth with way oil, and rub a thin film into the pores of the freshly cleaned gap surfaces. Next, place the gap in position on the lathe bed.

3. Back off the threaded dowel pin jam nuts until they are flush with the end of the pins, and drop the pins into the pin holes in the gap.

4. Jostle the gap closer to its final alignment until the pins seat naturally.

7. Wait 24 hours, and check for quality of mating. If unacceptable, use clamps and blocks of wood, and loosen and tighten the appropriate cap screws to draw-in and release certain areas of the gap to achieve the required alignment.

8. When satisfied with the alignment, tap the dowel pins the rest of the way into the gap until they are in a fully seated position, and thread the jack nuts down until they just contact the gap.

Machine Storage

To prepare your machine for long-term storage (a year or more):

If the machine is not properly prepared for storage, it may develop rust or corrosion. Use the recommendations in this section to ensure that the lathe remains in good condition for later use.

To prepare your machine for short-term storage (up to a year):

1. Pump out the old cutting fluid, and remove

and blow out lines with compressed air and a few drops of way oil.

2. DISCONNECT LATHE FROM POWER!

3. Thoroughly clean all unpainted, bare metal

surfaces, then apply a liberal coat of way oil.

4. Lubricate the machine as outlined in the lubrication section. Be sure to use the oil gun to purge all ball oilers and the oil passages with oil.

5. Cover and place the machine in a dry area that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make plastic guards cloudy.

6. Once or twice a month, depending on the ambient humidity levels in the storage environment, wipe down the machine as outlined in Step 3. Slide the carriage, tailstock, and steady rest down the lathe bed to make sure that way spotting is not beginning to occur.

7. Every few months, manually rotate all geardriven components a few times in several gear selections. This will keep the bearings, bushings, gears, and shafts well lubricated and protected from corrosion, especially during the winter months.

1. Run the lathe and bring all gearboxes to operating temperature, then drain and refill the all gearboxes with fresh oil.

2. Pump out the old cutting fluid, remove the lines, add a few drops of way oil into the lines, and blow out the lines with compressed air.

3. DISCONNECT LATHE FROM POWER!

4. Thoroughly clean all unpainted, bare metal

surfaces, then apply a liberal coat of way oil, a heavy grease, or rust preventative. Take care to ensure these surfaces are completely covered but that the rust preventative or grease is kept off of painted surfaces.

5. Lubricate the machine as outlined in the lubrication section. Be sure to use the oil gun to purge all ball oilers and the oil passages with oil.

6. Loosen or remove machine belts so they do not become stretched during the storage period. (Be sure to also affix a maintenance note near the power button as a reminder that the belts have been loosened or removed.)

7. Place a few moisture-absorbing desiccant bags inside of the electrical box.

8. Cover and place the machine in a dry area that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make plastic guards cloudy.

9. Slide the carriage, micrometer stop, tailstock, and steady rest down the lathe bed to make sure that way spotting is not beginning to occur.

SHOCK HAZARD. Working on wiring that is connected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts.

WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.

MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.

CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.

EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information included in this section, contact our Technical Support at (570) 546-9663.
