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-

-11-

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 Milling Machines

You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter/spindle. You can be severely cut or have fingers amputated from contact with rotating cutters. You can be blinded or struck by broken cutting tools, metal chips, workpieces, or adjustment tools thrown from the rotating spindle with great force. To reduce your risk of serious injury when operating this machine, completely heed and understand the following:

UNDERSTAND ALL CONTROLS. Make sure

you understand the function and proper use of all controls before starting. This will help you avoid making mistakes that result in serious injury.

AVOIDING ENTANGLEMENT. DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place and secure. Always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

WEAR FACE SHIELD. Always wear a face shield in addition to safety glasses. This provides more complete protection for your face than safety glasses alone.

USE CORRECT SPINDLE SPEED. Follow recommended speeds and feeds for each size and type of cutting tool. This helps avoid tool breakage during operation and ensures best cutting results.

INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately.

PROPERLY SECURE CUTTER. Firmly secure cutting tool or drill bit so it does not fly out of spindle during operation.

POWER DISRUPTION. In the event of a local power outage during operation, turn spindle switch OFF to avoid a possible sudden startup once power is restored.

CLEAN MACHINE SAFELY. Metal chips or shavings can be razor sharp. DO NOT clear chips by hand or compressed air that can force chips farther into machine—use a brush or vacuum instead. Never clear chips while spindle is turning.

SECURE WORKPIECE TO TABLE. Clamp workpiece to table or secure in a vise mounted to table, so workpiece cannot unexpectedly shift or spin during operation. NEVER hold workpiece by hand during operation.

PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other components work as intended. Perform routine inspections and all necessary maintenance. Never operate machine with damaged or worn parts that can break or result in unexpected movement during operation.

DISCONNECT POWER FIRST. To reduce risk of electrocution or injury from unexpected startup, make sure mill/drill is turned OFF, disconnected from power, and all moving parts have come to a complete stop before changing cutting tools or starting any inspection, adjustment, or maintenance procedure.

REMOVE CHUCK KEY & SPINDLE TOOLS. Always remove chuck key, drawbar wrench, and other tools used on the spindle immediately after use. This will prevent them from being thrown by the spindle upon startup.

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.

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following 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.)

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).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

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.

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

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.

Model G0827 (Mfd. Since 11/17)

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.

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.

Leveling Anchoring to Floor

Leveling machinery helps precision components, such as dovetail ways, remain straight and flat during the lifespan of the machine. Components on an unleveled machine 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.

See Figure 16 for an example of a high precision level available from Grizzly.

Serious injury or death can result from

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

Before the machine can be connected to the power supply, there must be an electrical circuit that meets the Circuit Requirements on Page 14, and the correct plug must be installed according to the instructions and wiring diagrams provided by the plug manufacturer.

If the plug manufacturer did not include instructions, the wiring of a generic NEMA 15 -15 plug is illustrated in the Wiring section on Page 64.

Test Run

Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components function properly.

If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again. The Troubleshooting table in the

Spindle Speed

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 mill controls to match the closest spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the cutting tool, as noted in Figure 43:

Recommended

Cutting Speed (FPM) x 12

Tool Diameter (in inches) x 3.14

= RPM

Cutting Speeds for High Speed Steel (HSS)

Cutting Tools

Workpiece Material Cutting Speed (sfm)

Copper 100

Cast Iron, soft 80

Mild Steel 90

Cast Steel 80

Alloy Steel, hard 40

Tool Steel 50

Stainless Steel 60

Titanium 50

Plastics 300-800

Wood 300-500

Note: For carbide cutting tools, double the cut-

ting speed. These values are a guideline only. Refer to the MACHINERY'S HANDBOOK for more detailed information.

Figure 44. Cutting speed table.

Double if using carbide cutting tool

Figure 43. Spindle speed formula for milling.

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 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. These sources will help you take into account all applicable variables to determine the best spindle speed for the operation.

To avoid damaging spindle, gears, or cutting tools when setting spindle speed range:

• Spindle rotation must be turned OFF and spindle must be at complete stop BEFORE you change spindle speed range.

• To avoid damaging moving parts inside headstock, never start spindle rotation without speed selector detent pins firmly seated in correct position.

-36-

Model G0827 (Mfd. Since 11/17)

Setting Vertical Spindle Speed

Use the charts below (see Figure 45) or those on the headstock when setting the spindle speed. With the spindle completely stopped, position the high/low range selector (see Figure 46) and spindle speed selectors (see Figure 47) as indicated by the spindle speed chart to set the desired spindle RPM. Position I on the range selector is low speed range; position II is high speed range.

Note: If necessary, rotate the spindle a little by hand to mesh the gears when changing speeds.

Low Range (I)

Setting Horizontal Spindle Speed

Use the chart below (see Figure 48) or the one on the rear column cover when setting the spindle speed. With the spindle completely stopped, position the range knob and spindle speed knobs (see Figure 49), as indicated by the spindle speed chart, to set the desired spindle RPM.

Note: If necessary, rotate the spindle a little by hand to mesh the gears when changing speeds.

Use Figure 50 and the descriptions below to understand the downfeed components that control the spindle downfeed travel.

Fine

Downfeed

Handwheel

Lock

Coarse

Downfeed

Lever

Selection

Lever

Coarse Downfeed

When the coarse downfeed is engaged, pull the coarse downfeed levers down to lower the spindle. An internal coil spring helps raise the spindle up when you stop applying downward pressure on the lever.

Note: To maintain control of the upward spindle travel and the rotating bit in your workpiece, always continue holding the lever until the spindle returns to the top position. Letting go of the coarse downfeed levers when the spindle is in the lowered position will cause the spindle to retract too quickly and slam up into the headstock or lift the workpiece and cause it to spin out of control.

The coarse downfeed hub features a graduated dial that measures spindle movement in 1" increments, with one full revolution equaling 5" of spindle travel. The dial has a thumbscrew that is used to adjust the dial to "0".

Figure 50. Spindle downfeed controls.

Coarse Downfeed Levers: Allow you to manu-

ally control downfeed travel of spindle in a rapid manner. The spindle automatically returns to the top position when pressure is released from the handle, making this ideal for drilling operations.

Fine Downfeed Handwheel: Manually controls downfeed travel in a slow, precise manner. Unlike coarse downfeed, the spindle does not automatically retract, which makes this ideal for fine positioning of the spindle/cutter for miling operations. The attached graduated dial has increments of

0.001" with one full revolution representing 0.100" of travel.

Selection Lever: When tightened, enables the fine downfeed handwheel; conversely, when loosened enables the coarse downfeed levers.

Quill Lock: Secures the quill in place for increased

stability during milling operations. Typically only used after first positioning spindle/cutter with fine downfeed handwheel.

-38-

Model G0827 (Mfd. Since 11/17)

Fine Downfeed

When the fine downfeed is engaged, the spindle only moves up or down when the handwheel (see Figure 51) is rotated (there is no automatic spindle return to the top position, as with the coarse downfeed controls). This level of control allows the spindle height to be locked in place with the quill lock when milling a flat surface across the face of a workpiece.

Note: The graduated dial on the fine downfeed handle measures spindle movement in 0.001" increments, with one full revolution equaling 0.100" of spindle travel. The dial has a thumbscrew that is used to adjust the dial to "0".

Using Fine Downfeed Controls

In the following example, the fine downfeed controls are used to mill 0.010" off a workpiece:

Use Z-axis crank to adjust workpiece surface

just below cutting tool, then secure the headstock with Z-axis lock lever.

Tighten selection lever (see Figure 51) to

engage fine downfeed handwheel.

Loosen quill lock.

Oil Amount Lubrication Frequency

Proper lubrication of ball oilers is done with a pump-type oil can that has a cone tip (see Page 40 for offerings from Grizzly). 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.

Push the 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, continue pumping the oil can until the oil runs clear. Move the components through the entire path of travel a few times to distribute the oil. When finished, wipe away the excess oil.

Hazards

As some coolant ages, dangerous microbes can proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by replacing the old coolant on a regular basis, as indicated in the maintenance schedule.

The important thing to keep in mind when working with the coolant is to minimize exposure to your skin, eyes, and respiratory system by wearing the proper PPE (personal protective equipment), such as splash-resistant safety glasses, longsleeve gloves, protective clothing, and a NIOSHapproved respirator.

Replace leadscrew alignment key, then align

bevel gear keyway with key as you slide gear onto leadscrew and mesh its teeth with drive gear.

Replace graduated dial ring and secure it with

knurled retaining ring—do not overtighten.

Slide handwheel onto leadscrew, align key-

way with leadscrew alignment key, then secure it with acorn nut removed in Step 2.

Move table with handwheel to check gear

movement and distribute grease on gears. If movement is not smooth, repeat Steps 2–8 until it is.

Repeat Steps 1–9 for Y-axis power feed.

BIOLOGICAL & POISON

HAZARD! Use the correct personal protection equipment when handling coolant. Follow federal, state, and fluid manufacturer requirements for proper disposal.

A small amount of coolant is lost during normal operation. Check the coolant reservoir regularly and fill it if necessary. We recommend changing the coolant every three months or sooner if it develops an unpleasant odor. However, be sure to follow the coolant manufacturer's instructions when checking, adding, or changing coolant.

Coolant Reservoir Capacity ..... 4.75 Gal. (18L)

ing operations.

Tip: As an alternate method, leave return

screen in place. For a dip stick, use a clean, metal tool that is narrow enough to fit through screen hole and long enough to measure coolant depth.

Tip: Alternately, slide rubber hose onto cool-

ant nozzle and point it into 5-gallon bucket.

Thoroughly clean out reservoir. Make sure

interior is dry before adding new coolant.

Note: Use a shop vacuum and a cleaning

solution that is compatible with type of coolant. For instance, if you are using a waterbase coolant, then use a water-base cleaning solvent. Also, use magnets to remove any metal chips left behind.

When reservoir is clean and dry, fill reservoir

with new coolant through hole under return screen.

Tip: Place a couple of magnets inside res-

ervoir under return screen to collect metal particles and keep them out of coolant pump.

Tensioning/

Replacing V-Belts

To ensure optimum power transmission from the horizontal spindle motor to the arbor, the V-belts must be in good condition (free from cracks, fraying, and wear) and properly tensioned. After the first 16 hours of belt life, re-tension the V-belts, as they will stretch and seat during this time.

All V-belts can be replaced by releasing the tension and rolling them off the pulleys, then rolling the new belts back onto the pulleys. Always replace V-belts with a matched set of three belts, or belt tension may not be even among the three belts and may cause premature belt failure.

Tramming Mill Head

After positioning the head at an angle and when your operation requires that the spindle axis be precisely perpendicular to the table, you must tram or align the spindle with the table to ensure the spindle is exactly 90° to the table.

Note: A precision-ground plate can be substituted for the parallel blocks. Keep in mind that the farther the indicator point can be placed from the spindle axis, the more accurate the alignment measurements will be.

To tram spindle to mill head:

DISCONNECT MACHINE FROM POWER!

This procedure involves mounting a dial test indicator to the quill or spindle, rotating it around the table, and adjusting the spindle axis (Z-axis) 90° to the table X- and Y-axes, as illustrated in Figure 94.

2. Prepare the mill for tramming by performing following tasks:

• Verify the table is clean by running your

hand over the top of it. If necessary, stone the table to remove all nicks and burrs, then clean off all debris.

• Position the table for the milling operation

you intend to perform after tramming— preferably centered with the saddle.

• Tighten any table, knee, quill, or ram locks

that should be tight during the intended milling operation.

Place parallel block underneath spindle.

4. Install indicator holder in spindle or on quill,

then mount indicator so that point is as parallel to the block as possible (see illustration in Figure 95).

We encourage you to research the many variations of spindle tramming to find the one that works best for you. If you do not already have a preference for performing this operation, use the following widely used procedure for accurately tramming the spindle to the table.

Keep in mind that all workpiece top surfaces are not exactly parallel with the table top. You may choose to tram the spindle to the top surface of the workpiece after it is mounted instead of that of the table.

5. To measure spindle alignment along X-axis, place parallel block directly under spindle and indicator across length of table, as illustrated in Figure 96.

Note: If you must position quill or knee to

accommodate above step, then review the tasks in Step 2 to make sure the mill is properly prepared for tramming.

Rotate spindle so that indicator point rests

in same manner on other end of block, then read dial.

— If indicator dial still reads zero or is within

the acceptable variance, continue on with Step 8.

— If indicator dial has moved from zero

beyond acceptable variance, you will need to compensate for that amount by rotating head left or right. Repeat Steps 6–7 until you are satisfied with the spindle axis alignment along table X-axis.

Note: Keep one of the rotation lock bolts

just snug so the head does not move loosely while you adjust it. Remember to tighten all the rotation lock bolts after adjusting the head.

Place parallel block directly under spindle

and across width of table, as illustrated in Figure 97.

Note: Your general goal in the next steps

should be to get the difference of the indicator readings between the ends of the parallel bar down to 0.0005". However, the acceptable variance will depend on the requirements for your operation.

Rotate spindle by hand so that indicator point

rests on one end of parallel block, as illustrated in Figures 95–96, then zero dial.

— If indicator dial still reads zero or is within

the acceptable variance, the spindle is precisely perpendicular to table in both X- and Y-axes, and tramming procedure is complete.

— If indicator dial has moved from zero

beyond acceptable variance, you will need to compensate for that amount by tilting head forward or backward. Repeat Steps 9–10 until you are satisfied with spindle axis alignment along table Y-axis.

Adjusting Leadscrew

Backlash

Leadscrew backlash is the amount of free play movement in the leadscrew (when the leadscrew moves but the table does not) after changing the direction of rotation.

A leadscrew must have a certain amount of backlash to rotate easily, but over time, it increases with wear. Generally, 0.005"–0.010" leadscrew backlash is acceptable to ensure smooth movement and reduce premature thread wear.

Adjusting Gibs

Gibs are tapered lengths of metal that are sandwiched between two moving surfaces. Gibs control the gap between these surfaces and how they slide past one another. Correctly adjusting the gibs is critical to producing good results.

Correctly positioning gibs is a matter of trial and error and patience. Tight gibs make table movement more accurate but stiff. Loose gibs make table movement sloppy but easier to do. The goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind.

Many experienced machinists adjust the gibs just to the point where they can feel a slight drag in table movement.

Screws on each end of the X- and Y-axis gibs allow gib adjustment to increase or decrease the friction between the sliding surfaces. The exception to this arrangement is the column dovetail way (Z-axis) gibs.

Adjusting X- & Y-Axis Gibs

1. Make sure all table locks are loose.

2. Loosen one gib adjustment screw

(see Figure 100) and tighten opposite screw same amount to move gib, while at same time rotating handwheel to move table until you feel slight drag in that path of movement.

2. Loosen four locking set screws.

Loosen four jam nuts on adjusting set screws,

and back out set screws two full turns. The gibs should now be free and loose.

Tighten adjusting set screws for each gib

alternately until both gibs are just touching dovetail way along their full length; then tighten locking set screws and jam nuts.

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected 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.
