1. READ and become familiar with the entire Instruction Manual. LEARN the tool’s application, limitations and possible hazards.

2. KEEP GUARDS IN PLACE and in working order.

3. REMOVE ADJUSTING KEYS AND WRENCHES.
   Form the habit of checking to see that keys and adjusting wrenches are removed from the tool before turning ON.

4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

5. DO NOT USE IN DANGEROUS ENVIRONMENTS. Do not use power tools in damp locations, or expose them to rain or snow. Keep work area well lit.

6. KEEP CHILDREN AWAY. All visitors and bystanders should be kept a safe distance from work area.

7. MAKE WORKSHOP CHILD PROOF with padlocks, master switches or by removing starter keys.

8. DO NOT FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed.

9. USE THE RIGHT TOOL. Do not force the tool or an attachment to do a job for which it was not designed.

10. USE PROPER EXTENSION CORDS. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will result in a drop in line voltage and in loss of power which will cause the tool to overheat. The table on page 7 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

11. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets or other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.

12. ALWAYS WEAR EYE PROTECTION. Any power tool can throw foreign objects into the eyes and could cause permanent eye damage. ALWAYS wear Safety Goggles (not glasses) that comply with ANSI Safety standard Z87.1. Everyday eyeglasses have only impact-resistant lenses. They ARE NOT safety glasses. NOTE: Glasses or goggles not in compliance with ANSI Z87.1 could seriously injure you when they break.

13. WEAR A FACE MASK OR DUST MASK.
    Sawing operation produces dust.

14. SECURE WORK. Use clamps or a vise to hold work when practical. It is safer than using your hand and it frees both hands to operate the tool.

    C. Do not overtighten the wheel nut.
    D. Use only flanges furnished with this grinder.

11. Always inspect grinding wheels prior to use for cracks, missing pieces, etc. Replace wheel immediately before use.

12. USE ONLY GRINDING WHEELS that comply with ANSI B7.1 and rated greater than 3450 RPM.

13. GUARD AGAINST ELECTRICAL SHOCK by preventing body contact with grounded surfaces.
    For example: pipes, radiators, ranges, refrigerator enclosures.

14. DO NOT use wheels with incorrect size holes.
    NEVER use wheel washers or wheel screws that are defective or incorrect, and NEVER touch a grinding wheel or other moving parts.

15. NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the grinding path of the wheel.

16. AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause your hand to move into the wheel. ALWAYS make sure you have good balance.

17. NEVER stand or have any part of your body in line with the path of the wheel.

18. DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches replaced by an authorized service center.

19. DO NOT TURN THE MOTOR SWITCH ON AND OFF RAPIDLY. This could cause the wheel to loosen and create a hazard. Should this ever occur, stand clear and allow the wheel to come to a complete stop. Disconnect your grinder from the power supply and retighten the wheel nut securely.

20. RISK OF INJURY DUE TO ACCIDENTAL STARTING. Do not use in an area where children may be present.

21. NEVER START THE GRINDER when the wheel is in contact with the work piece.

22. SECURE WORK. Always hold the work piece firmly against the work rest.

23. DO NOT USE THE BENCH GRINDER if the flange nut or clamp nut is missing or if the spindle shaft is bent.

24. FREQUENTLY clean grinding dust from beneath the grinder.

25. DO NOT OPERATE THIS TOOL WHILE UNDER THE INFLUENCE OF DRUGS, ALCOHOL OR ANY MEDICATION.

26. ALWAYS STAY ALERT. Do not allow familiarity (gained from frequent use of your grinder) to cause a careless mistake. ALWAYS REMEMBER that a careless fraction of a second is sufficient to inflict severe injury.

27. STAY ALERT AND EXERCISE CONTROL. Watch what you are doing and use common sense. Do not operate the tool when you are tired. Do not rush.

28. SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct other users. If you loan someone this tool, loan them these instructions also.

29. ALWAYS EASE THE WORKPIECE AGAINST THE ABRASIVE WHEEL when starting to grind. A harsh impact can break the wheel. Use light pressure when starting to grind. Too much pressure on a cold wheel can cause the wheel to crack.

30. USE ONLY FLANGES furnished with this bench grinder.

31. IF ANY PART OF THIS GRINDER IS MISSING or should break, bend, fail in any way, or should any electrical component fail to perform properly, shut off the power switch, remove the machine plug from the power surce and have damaged, missing, or failed parts replaced before resuming operation.

32. SAFETY SHIELD AND SPARK DEFLECTOR. The safety shields and spark deflectors are adjustable for operator convenience. Operating the grinder without these features attached could result in serious injury. Do not grind with the safety shield raised. Always wear safety glasses for personal protection.

33. WORK REST. The work rests are independently adjustable to compensate for wheel wear. Before grinding, make certain the work rests are adjusted properly. Generally, the object being ground is done slightly above the center of the grinding wheel.

34. Lawn mower blades are usually sharpened on only one edge and dressed up slightly on the other. Perform this sharpening process on both cutting ends of the blade. After sharpening, balance the blade by removing additional material.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS

WARNING
To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Use a separate electrical circuit for your tool. Your grinder is wired at the factory for 120 V operation. Connect to a 120 V, 5 Amp circuit and use a 5 Amp time delay fuse or circuit breaker. To avoid shock or fire, if power cord is worn, cut, or damaged in any way, have it replaced immediately.

GROUNDING INSTRUCTIONS
WARNING
This tool must be grounded while in use to protect the operator from electrical shock.
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN , grounding provides a path of least resistance for electric currents and reduces the risk of electric shock. This tool is equipped with an electrical cord that has an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching receptacle that is properly installed and grounded in accordance with all local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the receptacle, have the proper receptacle installed by a qualified electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in risk of electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electrical cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.
CHECK with a qualified electrician or service person if you do not completely understand the grounding instructions, or if you are not certain the tool is properly grounded.
USE only 3-wire extension cords that have three-pronged grounding plugs with three-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cords immediately.
Use a separate electrical circuit for your tool. This circuit must not be less than #18 wire and should be protected with a 5 Amp time lag fuse. Before connecting the motor to the power line, make sure the switch is in the off position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

GUIDELINES FOR EXTENSION CORDS
USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Use an extension cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power, overheating and burning out of the motor. The table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified technician before using it. Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

MINIMUM GAUGE FOR EXTENSION CORDS (AWG)

WARNING
This tool is for indoor use only. Do not expose to rain or use in damp locations.
This tool is intended for use on a circuit that has a receptacle like the one illustrated in Fig. 1. Fig. 1 shows a three-pronged electrical plug and receptacle that has a grounding conductor. If a properly grounded receptacle is not available, an adapter (Fig. 2) can be used to temporarily connect this plug to a two-contact grounded receptacle. The adapter (Fig. 2) has a rigid lug extending from it that MUST be connected to a permanent earth ground, such as a properly grounded receptacle box.

CAUTION
In all cases, make certain the receptacle is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

OPERATION

STARTING AND STOPPING THE GRINDER (FIG. M)
The “ON / OFF” switch has a removable, black plastic key. With the key removed from the switch, unauthorized and hazardous use by children and others is minimized.

1. To turn the grinder “ON”, insert key (1) into the slot of the switch (2), and move the switch to the “ON” position.
2. To turn the grinder “OFF”, move the switch to the “OFF” position.
3. To lock the switch in the “OFF” position, grasp the end, of the switch key, and pull it out.
4. With the switch key removed, the switch will not operate.
5. If the switch key is removed while the grinder is running, it can be turned “OFF” but cannot be restarted without inserting the switch key.

CAUTION
Always lock the switch “OFF” when the grinder is not in use. Remove the key and keep it in a safe place. In the event of a power failure, blown fuse, or tripped circuit breaker, turn the switch “OFF” and remove the key, preventing an accidental startup when the power comes on.

ADJUSTING THE SPEED OF GRINDER (FIG. N)
Your grinder is equipped with a variable speed control knob. The speed of the grinder may be adjusted by simply rotating the variable speed control knob (1).

1. To increase speed, rotate the variable speed control knob (1) clockwise.
2. To reduce speed, rotate the variable speed control knob (1) counterclockwise.

GENERAL OPERATION
CAUTION
Keep all bystanders a safe distance away from the tool and not in direct line, front or back of the grinder.

1. Your bench grinder has a medium wheel (60 grit) for medium material removal and general purpose grinding, and a coarse wheel (36 grit) for fast material removal.
2. To operate the bench grinder, always wear safety glasses and turn the tool on while standing at the side and not in front of the grinder. Allow it to reach full speed before grinding.
3. Hold the work piece firmly against the tool rest. Hold very small pieces with pliers or other suitable clamps.
4. Feed the work piece smoothly and evenly into the grinding wheel.
5. Move the work piece slowly and avoid jamming the work piece against the wheel. If the wheel tends to slow down from excessive force, you should occasionally release the pressure to let the wheel return to full speed.
6. Grind only on the face of the grinding wheel and never the side of it. (Some wheels are designed for side grinding and will say so on their blotters/ cardboard disc.)

CAUTION
Prolonged grinding will cause most materials to become hot. Use care when handling such materials.
SCISSORS
If possible, take the scissors apart to make the sharpening operation easier and safer. Remove material only from the outside surface and work from the heavy end of the blade toward the tip.
KNIVES
Remove metal from both faces of most knives, working from the heavy end of the blade toward the tip.
SCREWDRIVERS
The end of a properly sharpened screwdriver will be a perfect rectangle, absolutely flat and perpendicular to the center line of the shank. The two sides and two faces will taper outward from the edge of the shoulder or shank. They should be flat with intersecting faces perpendicular. Hold each face of the screwdriver against the wheel to true it up, then ease the end straight into the stone to grind it true.
TWIST DRILL BITS (FIG. Q)
Drill bits are best sharpened on a sharpening jig, available at most hardware stores, but can be “dressed up” on your grinder. Begin on one side of the point at the existing angle, then twist the bit while maintaining a constant angle with grinding surface. Sharpen only the tip. This technique requires considerable practice, so take your time and make a few “dry runs” first with the grinder off. Be sure to maintain the original cutting edge angle as this is important to the efficiency of your bits. One tool rest has a V-groove that is correctly angled for most drill bits.

LAWN MOWER BLADES
Lawn mower blades are usually sharpened on only one side and dressed up slightly on the other. After sharpening, be sure to balance the blade by removing additional material from the heavy end. There are a number of inexpensive cone balancers on the market
for this purpose. Unbalanced blades can cause serious crank shaft damage to your lawn mower. Always remove spark plug wires from the mower before servicing the blades to prevent accidental starting.

CAUTION
For your own safety, turn switch “OFF” and remove plug from power source outlet before adjusting and maintaining your bench grinder. If power cord is worn, cut or damaged in any way, have it replaced immediately.

GENERAL

1. Regularly check the tool and use a soft brush to remove accumulated dust. Wear safety goggles to protect your eyes while cleaning.

2. If the body of the grinder needs cleaning, wipe it down with a soft, damp cloth. A mild detergent can be used. Do not use alcohol, petrol or other similar cleaning agents. Do not make contact with the grinding wheels with any damp cloth.

3. Always make sure the eyeshields are transparent and not blocking the view of the grinding wheel.

4. In normal use, grinding wheels may become cracked, grooved, rounded at the edges, chipped, out of true or loaded with foreign material. Cracked wheels should be replaced IMMEDIATELY. While any of the other conditions can be remedied with a  dressing tool (included), new wheels sometimes require dressing to make them round.
   MAINTENANCE

5. If you must replace a wheel be sure to obtain one with a safe rated speed at least as high as the “NO LOAD” RPM marked on your grinder’s nameplate.
   Replacement wheels must have a 5/8 in. (15.88 mm) center hole, 8 in. (200 mm) diameter and should be a maximum of 1 in. (25 mm) wide.

CAUTION

• Never use caustic agents to clean the plastic parts of the tool.
• Water must never come into contact with the grinder.
• The use of any other accessories is not recommended and may result in serious injury.
