Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed. Only allow trained/supervised people to use this machine. When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make your workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use machinery in areas that are wet, cluttered, or have poor lighting. Operating machinery in these areas greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental alertness is required for safe operation of machinery. Never operate under the influence of drugs or alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You can be shocked, burned, or killed by touching live electrical components or improperly grounded machinery. To reduce this risk, only allow qualified service personnel to do electrical installation or repair work, and always disconnect power before accessing or exposing electrical equipment.

DISCONNECT POWER FIRST. nect machine from power supply BEFORE making adjustments, changing tooling, or servicing machine. This prevents an injury risk from unintended startup or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved safety glasses or a face shield when operating or observing machinery to reduce the risk of eye injury or blindness from flying particles. Everyday eyeglasses are NOT approved safety glasses.

Always discon-

Page 14

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine for damaged, loose, or mis-adjusted parts—or any condition that could affect safe operation. Immediately repair/replace BEFORE operating machine. For your own safety, DO NOT operate machine with damaged parts!

MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab and pull the plug—NOT the cord. Pulling the cord may damage the wires inside. Do not handle cord/plug with wet hands. Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-9663.

Additional Safety for Metal Lathes

Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects can also strike nearby operators with deadly force. To minimize the risk of getting hurt or killed, anyone operating this machine MUST completely heed the hazards and warnings below.

CLOTHING, JEWELRY & LONG HAIR. Tie back

long hair, remove jewelry, and do not wear loose clothing or gloves. These can easily get caught on rotating parts and pull you into lathe.

ROTAT ING PARTS. Always keep hands and body at a safe distance from rotating parts—especially those with projecting surfaces. Never hold anything against rotating workpiece, such as emery cloth, that can pull you into lathe.

GUARDING. Guards and covers protect against entanglement or flying objects. Always ensure they are properly installed while machine is running.

ADJUSTMENT TOOLS. Remove all chuck keys, wrenches, and adjustment tools before turning lathe ON. A tool left on the lathe can become a deadly projectile when spindle is started.

SAFE CLEARANCES. Before starting spindle, verify workpiece has adequate clearance by handrotating it through its entire range of motion.

NEW SETUPS. Test each new setup by starting spindle rotation at the lowest speed and standing to the side of the lathe until workpiece reaches full speed and you can verify safe rotation.

SPINDLE SPEEDS. Using spindle speeds that are too fast for the workpiece or clamping equipment can cause rotating parts to come loose and strike nearby people with deadly force. Always use slow spindle speeds with large or non-concentric workpieces. Never exceed rated RPM of the chuck.

LONG STOCK SAFETY. Long stock can whip violently if not properly supported. Always support any stock that extends from the chuck/headstock more than three times its own diameter.

CLEARING CHIPS. Metal chips can be razor sharp. Avoid clearing them by hand or with a rag. Use a brush or vacuum instead.

SECURE WORKPIECE. An improperly secured workpiece can fly off spindle with deadly force. Make sure workpiece is properly secured before starting the lathe.

CHUCKS. Chucks can be heavy and difficult to hold. During installation and removal, protect your hands and precision bed ways by using a chuck cradle or piece of plywood over the bed ways. Use lifting equipment, as necessary, for large chucks.

STOPPING SPINDLE. Always allow spindle to completely stop on its own, or use a brake, if provided. Never put hands or another object on a spinning workpiece to make it stop faster.

CRASHING. A serious explosion of metal parts can occur if cutting tool or other lathe component hits rotating chuck or a projecting part of workpiece. Resulting metal fragments can strike nearby people and lathe will be seriously damaged. To reduce risk of crashing, ALWAYS release automatic feeds after use, NEVER leave lathe unattended, and CHECK all clearances before starting lathe.

COOLANT SAFETY. Coolant can become very toxic through prolonged use and aging. To minimize toxicity, change coolant regularly. When using, position nozzle properly to avoid splashing operator or causing a slipping hazard on floor.

TOOL SELECTION. Cutting with incorrect or dull tooling increases risk of injury from broken or dislodged components, or as a result of extra force required for operation. Always use sharp tooling that is right for the job.

SANDING/POLISHING. To reduce risk of entanglement, never wrap emery cloth around rotating workpiece. Instead, use emery cloth with the aid of a tool or backing board.

MEASURING WORKPIECE. To reduce risk of entanglement, never measure rotating workpieces.

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.

Like all machines there is danger associated with Model G0949G. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

-14-

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results.

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 electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage may occur if machine is not properly grounded and connected to 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 specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure 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.)

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.

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 can 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).

Cleanup

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)

Site Considerations

Weight Load

Refer to the 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.

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that 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.

Anchoring to Floor

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.

Number of Mounting Holes ............................ 8

Diameter of Mounting Hardware

Anchoring to Concrete Floors

.................1⁄2"

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.

Recheck 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.

If needed, use metal shims between the lathe bed and chip pan when leveling the machine.

Spindle Break-In

Before subjecting the spindle to operational loads, it is essential to complete the break-in process. This helps maximize the 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 Ru n 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.

To perform spindle break-in:

Run lathe at spindle speeds of 500, 1300,

and 1800 RPM. Run for a minimum of 5 minutes at each speed in each direction of rotation.

Chuck & Faceplate

This lathe is equipped with a D1-type spindle nose. This type of spindle uses camlocks that are adjusted with a chuck key to securely mount a chuck or faceplate with repeatable precision and ease.

This lathe ships with the 3-jaw chuck installed. This is a scroll-type chuck where all three jaws move in unison when the chuck key is used.

The included 4-jaw chuck features independent jaws, which are used for square or unevenlyshaped stock, and to mount work that needs to be adjusted to near-zero total indicated runout.

The included faceplate has slots for T-bolts that hold standard or custom clamping hardware. With the correct clamping hardware, a faceplate offers a wide range of uses, including machining nonconcentric workpieces, straight turning between centers, off-center turning, and boring.

Tailstock

The tailstock is typically used to support long workpieces at the side opposite the spindle, using a live or dead center. It can also hold a tapered drill bit (or a drill chuck with a regular drill bit) for boring holes. Unlike boring done with a drill press where the workpiece is fixed and the drill bit rotates, the drill bit in a tailstock remains stationary while the workpiece is rotated by the spindle.

The entire tailstock can be repositioned and locked in place along the length of the bed. An independently controlled offset adjustment allows the upper part of the tailstock to move perpendicular to the bedways so it can be aligned with the spindle center (for concentric turning) or offset from the spindle center (for tapered turning).

The tailstock quill also features independent adjustment controls that allow it to be advanced toward the spindle or locked firmly in position.

Installing Tooling

Note: If the tooling has an open hole in the end,

then a screw can be threaded into the end of the tool to provide a solid surface for the quill pin to push against when the quill is retracted for tool removal. Otherwise, removal of such tooling may be difficult.

forced out of quill.

The tailstock quill can be offset from the spindle centerline for turning tapers. Offsetting the quill toward the front of the lathe results in a taper at the tailstock end. Conversely, offsetting the quill toward the back of the lathe results in a taper at the spindle end.

This tailstock uses a quill with an MT#3 taper that accepts tapered arbors and drill bits (see Figure 39).

With tailstock locked in place, unlock quill,

To offset tailstock:

This is an essential adjustment that should be verified or performed each time the tailstock is used to turn concentric workpieces between centers or immediately after offsetting the tailstock when turning a taper. If the tailstock is not aligned with the spindle centerline when it is supposed to be, turning results will be inaccurate along the length of the workpiece.

To align tailstock to spindle centerline:

Note: As long as this dead center remains

unmoved in the chuck, its point will remain true to the spindle centerline. However, if the center is removed and later returned to the chuck, the point must be re-turned to once again be true with the spindle centerline.

To remove the sleeve and center from the spindle, insert a piece of round bar stock (or similar) through the outside end of the spindle. Have another person hold onto the sleeve and center with a gloved hand or shop rag, then tap the bar stock to knock the sleeve loose.

Either a carbide-tipped dead center or live center can be used in the tailstock. Mounting instructions are the same for both. The

A dead center is a one-piece center that does not rotate with the workpiece and is used to support long, slender workpieces.

Use the dead center in the spindle for operations where the workpiece rotates with the center and does not generate friction.

The tip of the center must be generously lubricated during the operation to avoid premature wear and maximize smooth operation. Using low spindle speeds will also reduce the heat and wear from friction.

Aligning Cutting Tool with Spindle

There are a number of ways to check and align the cutting tool to the spindle centerline. If necessary, you can raise the cutting tool by placing steel shims underneath it. The shims should be as long and as wide as the cutting tool to properly support it.

Below are two common methods:

• Move the tailstock center over the cross slide

Manual FeedSpindle Spider

This lathe is equipped with a set of outboard spindle supports otherwise known as a "spider" (see Figure 58).

Spider

Figure 58. Spindle spider components.

Remove spider screws when not in use. Always DISCONNECT LATHE FROM POWER when installing, removing, or adjusting spider screws. Ignoring this warning can lead to personal injury or machine damage.

The spider is especially designed for supporting gun barrels during chambering operations; however, it is a great support option for almost any long workpiece that extends through the outboard side of the spindle.

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

When spider screws are installed, always use the jam nuts to lock each spider screw in position. Merely tightening the spider screws against the workpiece and leaving the jam nuts loose is not safe. Spiders screws that loosen during operation can crash into the lathe end cover.

The cutting tool can be manually fed into the workpiece using the carriage, cross slide, and compound rest handwheels shown below.

Carriage Handwheel

The carriage handwheel moves the carriage left or right along the bed. It has a graduated dial with

0.01" increments. One full revolution moves the carriage 1.2".

Cross Slide Handwheel

The cross slide handwheel moves the tool toward and away from the work. Adjust the position of the graduated scale by loosening the thumb knob, holding the handwheel with one hand and turning the dial with the other, then tightening the thumb knob. The cross slide handwheel has a direct-read graduated dial, which shows the total amount of material removed from the diameter of the workpiece. The dial has 0.002" increments, and one full revolution moves the slide 0.2". Rotate the dial collar 180° to read in metric units.

Cross Slide Handwheel

The compound rest handwheel moves the cutting tool linearly along the set angle of the compound rest. Adjust the position of the graduated scale in a similar manner with handwheel and dial. The compound rest angle is set by hand-rotating it and securing in place with four hex nuts. The compound rest has an indirect-read graduated dial with 0.001" (0.025mm) increments. One full revolution of the handwheel moves the slide 0.1".

Spindle Speed

Using the correct spindle speed is important for getting maximizing tool life.

To set the spindle speed for your operation, you will need to: 1) Determine the

spindle speed

for the cutting task, and 2)

lathe

controls to produce the required spindle speed.

Many variables affect the optimum spindle speed to use for any given operation important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown below.

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 the desired finish and optimize tool life.

Power Feed

Both the carriage and cross slide have power feed capability when the carriage is engaged with the feed rod. The rate that these components move per revolution of the feed rod is controlled by the quick-change gearbox levers and dial positions and the end gear configuration.

The feed per revolution and the spindle speed must be considered together—this is the feed rate. The sources you use to determine the optimum spindle speed for an operation will also provide the optimal feed to use with that spindle speed.

To avoid damaging the lathe, ALWAYS make sure the spindle is completely stopped BEFORE using the headstock controls to make changes.

Power Feed Controls

Use Figures 62–66 and the following descriptions to understand the power feed controls.

Note: Before using power feed, you may have to reconfigure the end gears, depending on how they are set up. Refer to End Gears on Page 51 for detailed instructions.

Often, the experienced machinist will use the feeds and speeds given in their reference charts or web calculators as a starting point, then make minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.

The carriage can alternately be driven by the leadscrew for threading operations. However, this section only covers the use of the power feed option for the carriage and cross slide components for non-threading operations. To learn how to power the carriage for threading operations, refer to Threading on Page 54.

If the feed selection lever and the half nut are engaged at the same time, machine damage could occur. Even though there is a lock-out device to prevent this, it could break if forced.

Before using any power feed or threading operations, make sure to loosen carriage lock first. Ignoring this warning can cause serious machine damage.

Figure 62. Power feed controls on the

headstock.

A. Feed Direction Selector: Selects direction

of carriage travel for power feed relative to the rotation direction of spindle. When lever is positioned as shown in Figure 62, carriage will move left (toward the spindle), or cross feed will travel toward rear of lathe when spindle is rotating counterclockwise (or toward front of lathe). When lever is positioned in opposite direction, carriage will move right (toward tailstock), or cross feed will travel toward front of lathe when spindle is rotating clockwise (or toward the rear of lathe).

B. Feed Rate Selector: Sets desired feed/

thread rate. Refer to Setting Power Feed Rate subsection on Page 50 for detailed instructions.

When lever is in left and down position, cross

slide is selected. When lever is in right and up position, carriage is selected. In middle position, neither cross slide or carriage will move.

Note: When using this lever, you may need

to slightly rotate the handwheel of the component you are trying to engage, so that the apron gears can mesh.

faces with an oiled rag.

Every 50 Hours

• Lubricate end gears (Page 64).

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Guards or covers removed.

• E-Stop button not working correctly or not requiring you to reset it before starting the machine again.

• Oil level not visible in the sight glasses.

• Damaged or malfunctioning components.

Daily, Before Operations

• Check/add headstock oil (Page 60).

• Check/add gearbox oil (Page 61).

• Check/add apron oil (Page 62).

• Add oil to the ball oilers (Page 63).

• Clean/lubricate the leadscrew (Page 63).

• Disengage the feed lever and feed selection lever on the apron (to prevent crashes upon startup).

• Ensure carriage lock bolt is loose.

Every 1000 Operating Hours

• Change the headstock oil (Page 60).

• Change the gearbox oil (Page 61).

• Change the apron oil (Page 62).

Annually

• Check/level bedway (Page 24).

Cleaning/Protecting

Because of its importance, we recommend that the cleaning routine be planned into the workflow schedule.

Typically, the easiest way to clean swarf from the machine is to use a wet/dry shop vacuum that is dedicated for this purpose. The small chips left over after vacuuming can be wiped up with a slightly oiled rag. Avoid using compressed air to blow off chips, as this may drive them deeper into the moving surfaces or cause sharp chips to fly into your face or hands.

All unpainted and machined surfaces should be wiped down daily to keep them rust free and in top condition. This includes any surface that is vulnerable to rust if left unprotected (especially parts that are exposed to water soluble cutting fluid). Use a quality ISO 68 way oil (see Page 57 for offerings from Grizzly) to prevent corrosion.

Before lubricating the bedways (see Figure 99), clean them with mineral spirits. Apply a thin coat of oil along the length of the bedway. Move the steady rest, carriage, and tailstock to access the entire length of the bedways. If the lathe is in a moist or dirty environment, increase the lubrication frequency.

Bedways

Figure 99. Bedways.

This lathe has 16 ball oilers that should be oiled on a daily basis before beginning operation. Refer to Figures 100–103 for their locations.

Ball Oilers

Proper lubrication of ball oilers is done with a pump-type oil can that has a plastic or rubberized cone tip. We do not recommend using metal needle or lance tips, as they can push the ball too far into the oiler, break the spring seat, and lodge the ball in the oil galley.

Lubricate the ball oilers before and after machine use, and more frequently under heavy use. When lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the rubber or plastic tip of the oil can nozzle against the ball oiler to create a hydraulic seal, then pump the oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep pumping the oil can until the oil runs clear. When finished, wipe away any excess oil.

Longitudinal Leadscrew

Oil Type .... Grizzly T23962 or ISO 68 Equivalent

Oil Amount Lubrication Frequency

Before lubricating the leadscrew (see Figure 102 on Page 64), clean it first with mineral spirits. A stiff brush works well to help clean out the threads. Make sure to move the carriage out of the way, so you can clean the entire length of the leadscrew.

Apply a thin coat of oil along the length of the leadscrew. Use a stiff brush to make sure the oil is applied evenly and down into the threads.

Note: In some environments, abrasive material can become caught in the leadscrew lubricant and drawn into the half nut. In this case, lubricate the leadscrew with a quality dry lubricant.

Handling & Care

Make sure to clean and lubricate any gears you install or change. Be very careful during handling and storage—the grease coating on the gears will easily pickup dirt or debris, which can then spread to the other gears and increase the rate of wear.

Make sure the end-gear cover remains closed whenever possible to keep the gears free of dust or debris from the outside environment.

Lubricating

1. DISCONNECT MACHINE FROM POWER!

Remove end-gear cover and remove all end

gears shown in Figure 104 on Page 64.

Clean end gears thoroughly with mineral spir-

its to remove old grease. Use a small brush if necessary to clean between teeth.

Clean shafts, and wipe away any grease

splatters in the vicinity and on inside of the end-gear cover.

Using clean brush, apply thin layer of grease

on gears. Make sure to get grease between gear teeth, but do not fill teeth valleys.

Install end gears and mesh them together

with an approximate 0.002"–0.004" backlash. Once gears are meshed together, apply small dab of grease between them where they mesh together—this grease will be distributed when gears rotate and recoat any areas scraped off during installation.

3. Thoroughly clean all unpainted, bare metal

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

. Lubricate machine as outlined in the lubri-

cation section. Be sure to use an oil can to purge all ball oilers and oil passages with fresh oil.

Place a few moisture absorbing desiccant

packs inside of electrical box.

Loosen or remove V-belt so it does not

become stretched during the storage period. (Be sure to place a maintenance note near power button as a reminder that belt has been loosened or removed).

Cover lathe and place it 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.

7. Re-install end-gear cover before reconnecting lathe to power.

Machine Storage

To prevent the development of rust and corrosion, the lathe must be properly prepared if it will be stored for a long period of time. Doing this will ensure the lathe remains in good condition for later use.

Preparing Lathe for Storage

1. Run lathe and bring all reservoirs to operating

temperature, then drain and refill them with clean oil.

DISCONNECT MACHINE FROM POWER!

Every few months, rotate by hand all gear-

driven components a few times in several gear selections. This will keep bearings, bushings, gears, and shafts well lubricated and protected from corrosion—especially during the winter months.

Slide carriage, tailstock, and steady rest

down lathe bed to make sure that way spotting is not beginning to occur.

Bringing Lathe Out of Storage

1. Re-install V-belt and tension it (refer to Page

73) if you removed it for storage purposes.

Remove moisture-absorbing desiccant packs

from electrical box.

Repeat Test Run and Spindle Break-In pro-

Backlash Adjustment

3. Rotate cross slide handwheel clockwise to

feed leadscrew nut out from under cross slide, as shown in Figure 106.

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 graduated dial.

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.

Cross Slide Gib

Make sure the bedways and leadscrew have been cleaned and lubricated before any adjustments. Refer to Lubrication on Page 60 for instructions and lubricant specifications.

To adjust cross slide gib:

1. DISCONNECT MACHINE FROM POWER!

Loosen locking set screw (see Figure 108).

In general, loose gibs cause poor finishes and tool chatter; however, over-tightened gibs cause premature wear and make it difficult to turn the handwheels.

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, which moves and holds the gib. Depending upon which direction the gib moves, the space between the sliding ways increases or decreases to control the rigidity of the cross slide and compound slide.

Before adjusting the gibs, loosen the locks for the device so that the gibs can freely slide during adjustment, then lubricate the ways.

The gib adjustment process usually requires some trial-and-error. Repeat the adjustment process as necessary until you find the best balance between loose and stiff movement. Most machinists find that the ideal gib adjustment is one where a small amount of drag or resistance is present, yet the handwheels are still easy to move.

Saddle Gib

The saddle gib is located on the bottom of the back edge of the cross slide (see Figure 110). This gib is designed differently than the cross or compound slide gibs. Instead of being a wedgeshaped plate, it is a flat bar. The gib pressure is applied by four set screws. Jam nuts secure these set screws in place, so they will not loosen during operation.

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 two set screws.

Leadscrew Shear Pin

Replacement

To replace leadscrew shear pin:

DISCONNECT MACHINE FROM POWER!

2. Place quick-change gear levers in neutral.

A straight 5 x 20mm brass shear pin (see Figure

116) holds the leadscrew and the drive hub

together. The pin is designed to break and disengage the power transfer to the leadscrew to help protect more expensive lathe components in the case of a carriage crash or the lathe is overloaded.

Adjustment

This lathe is equipped with a feed rod clutch, shown in Figure 118, that connects the feed drive hub with the feed rod through a set of springloaded ball bearings. This clutch helps protect the apron feed system from overload. The feed rod clutch comes set from the factory, and unless there is a problem, it needs no adjustment.

Feed Rod

Drive Hub

Figure 118. Feed rod clutch.

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 incorrectly tightened 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.

To adjust feed rod clutch:

DISCONNECT MACHINE FROM POWER!

2. Move FWD/REV switch to "0" (see Figure

119) so feed rod can be rotated by hand.

FWD/REV Switch

Figure 119. FWD/REV switch set to "0".

— If clutch slips during normal work loads,

increase clutch spring pressure by tightening each of four clutch drive set screws shown in Figure 118 one full turn, then recheck for slippage.

— If clutch does not slip when it should,

reduce clutch spring pressure by loosening each of four clutch set screws one full turn, then recheck for slippage.

Never completely tighten the feed clutch past its normal setting in an attempt to completely eliminate clutch slip. Doing so will void the warranty, and can lead to a nonslipping clutch, resulting in catastrophic gearbox damage.

Bearing Preload

4. Remove chuck (see Page 33), then shift spin-

dle to neutral by moving FWD/REV switch to "0" (see Figure 119 on Page 75).

This lathe is shipped from the factory with the spindle bearing preload adjusted. If the spindle ever develops a bit of end-play and the workpiece finish suffers, you can adjust the bearing preload to remove the end-play and improve the workpiece finish.

Adjusting the bearing preload requires using a spanner wrench or a punch and hammer. You can either purchase the spanner wrench at a tool store or fabricate one, using the diagram shown in Figure 120.

Fabricate from CRS or HRS bar stock

Using a spanner wrench, or hammer and

punch, rotate outer spanner nut (see Figure 121) counterclockwise and remove it.

bring lathe to normal operating temperature.

DISCONNECT MACHINE FROM POWER!

3. Remove end gear cover.

Loosen inner spanner nut one turn.

Note: You may have to tap on the outboard

end of the spindle as explained in Step 8 on Page 77, to help unload the spindle and break the spanner nut loose.

-76-

Model G0949G (Mfd. Since 01/22)

Page 79

Place a wooden block over outboard end

of spindle, and tap it a few times with a small sledge or heavy dead blow hammer (see Figure 122).

Insert chuck key into a cam socket to prevent

11.

spindle from turning, then tighten inner spanner nut until dial indicator needle just stops moving (see Figure 124).

Note: Your goal is to slide the spindle forward

just enough to introduce spindle end-play that you can feel by hand.

Figure 122. Introducing detectable end-play.

9. Place a dial indicator on cross slide and move

carriage toward headstock until contact point of indicator touches spindle face, as shown in Figure 123.

Note: For convenience and accuracy, we

recommend having another person watch the dial while you tighten the inner spanner nut.

Figure 124. Adjusting spindle bearings.

While tightening the inner spanner nut,

rock the spindle back and forth slightly with the chuck 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 no spindle end-play and no bearing preload. It is important that you find this point without tightening the spanner nut too much and inadvertently preloading the spindle bearings.

Figure 123. Example of dial indicator setup.

10.

Move carriage an additional 0.100" toward

headstock.

Model G0949G (Mfd. Since 01/22)

If you think you have gone past the zero end-

play point, unload the bearings by repeating Steps 8–9, then re-tighten the inner spanner nut until it has reached the zero end-play position.

-77-

Page 80

Tighten inner spanner nut an additional 1⁄16"

12.

along its circumference. See Figure 125 for an example of this measurement.

To confirm bearings are correctly preloaded:

Re-attach all removed lathe components and

prepare lathe for operation.

Figure 125. Final spanner nut rotation.

Without allowing inner spanner nut to tighten

13.

any further, install and tighten outer spanner nut against inner nut (see Figure 126).

IMPORTANT: DO NOT overtighten outer

spanner nut because additional preload can force bearings even tighter against races in the headstock and cause headstock to compress, crack, or cause bearing failure.

Install chuck and tighten jaws.

3. Set spindle speed to its highest setting.

4. Connect lathe to power and turn lathe spindle

ON.

Let lathe run for 20 minutes, periodically

shutting it down a few times and checking temperature.

IMPORTANT: Stop running lathe if the tem-

perature gets too hot. If you can not comfortably touch spindle nose immediately disconnect machine from power.

Turn spindle OFF, disconnect lathe from

power, and check temperature of spindle.

— If spindle nose is slightly warm to the

touch, you have correct bearing preload.

— If spindle nose is hotter than you can com-

fortably keep your hand on, preload is too tight and you must repeat bearing preload adjustment procedure. When repeating the procedure, rotate the inner spanner nut a little less during Step 12 in the preceding instructions.
