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.

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.

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.
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.
No adapter should be used with plug. If plug does not fit available receptacle, or if

Anchor studs and lag shield anchors with lag bolts (see Figure 6) are two popular methods for anchoring an object to a concrete floor. We sug­gest you research the many options and methods for mounting your machine and choose the best that fits your specific application.
Note: If necessary, use shims to make sure
there are no gaps between the base and the floor to avoid cracking or warping the cast iron.
NOTICE
We strongly recommend securing your machine to the floor if it is hardwired to the power source. Consult with your electrician to ensure compliance with local codes.
Mounting to Shop
Floor
Although not required, we recommend that you mount your new machine to the floor. Because this is an optional step and floor materials may vary, floor mounting hardware is not included. Generally, you can either bolt your machine to the floor or mount it on machine mounts. Both options are described below. Whichever option you choose, it is necessary to level your machine with a precision level.
Anchor Stud
Lag Shield Anchor & Bolt
Figure 6. Typical fasteners for mounting to
concrete floors.
Using Machine Mounts
Using machine mounts, shown in Figure 7, gives the advantage of fast leveling and vibration reduc­tion. The large size of the foot pads distributes the weight of the machine to reduce strain on the floor.
NOTICE
Anchor studs are stronger and more per­manent alternatives to lag shield anchors; however, they will stick out of the floor, which may cause a tripping hazard if you decide to move your machine.

3. Use one-shot oiler to lubricate ways (Page 27).
4. Adjust gibs properly (Page 31).
1. Use correct spindle RPM and feed rate (Page 21).
2. Sharpen/replace tooling; use correct tooling for operation.
3. Check for proper spindle rotation for tooling.
4. Check that clamping is tight and sufficient for the operation; make sure mill vise is tight to table.
5. Adjust gibs properly (Page 31).

Adjusting Gibs

Gibs control the accuracy of the table movements along the ways. Tight gibs make the movements more accurate, but harder to move. Loose gibs make the movements sloppy, but easier to move. The goal of gib adjustment is to remove unnec­essary sloppiness without causing the ways to bind.
NOTICE
Excessively loose gibs may cause poor workpiece finishes, and may cause undue wear of sliding surfaces and ways. Over­tightening the gibs may cause premature wear of these sliding devices.
Each sliding surface for the table, saddle, and knee has a tapered gib that is sandwiched between the stationary and moving surfaces. The saddle and knee have a gib on both sides. There are two adjustment screws, one on each end of each gib, that move the tapered gib back and forth increasing or decreasing friction of the slid­ing surfaces.

DISCONNECT THE MILL FROM POWER BEFORE ADJUSTING THE GIBS!
Loosen one adjustment screw and tighten the other the same amount to move the gib until you feel a slight drag in that path of movement.
Refer to Figures 41–43 for the locations of the table, saddle, and knee gib adjustment screws.

Leadscrew backlash is the amount of motion the leadscrew rotates before the device begins to move. Leadscrews always have a certain amount of backlash that will increase with wear. Generally,
0.005"–0.010" of backlash is acceptable.
The backlash of the longitudinal and cross leadscrew can be adjusted by changing the gap in the leadscrew nuts (see Figures 44–45).

Use a 5mm hex wrench to tighten or loosen the cap screws on the leadscrew nuts shown in Figures 44–45, then test the amount of backlash by slowly rocking the handwheels back-and-forth.

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.
The photos and diagrams included in this section are best viewed in color. You can view these pages in color at www.grizzly.com.
