1. DO NOT OPERATE THIS MACHINE until it is completely

assembled and installed according to the instructions. A

machine incorrectly assembled can cause serious injury.

2. OBTAIN ADVICE from your supervisor, instructor, or

another qualified person if you are not thoroughly familiar

with the operation of this machine. Knowledge is safety.

3. FOLLOW ALL WIRING CODES and recommended

electrical connections to prevent shock or electrocution.

4. ALWAYS USE THE PROVIDED BLOTTER AND WHEEL

FLANGES to mount the grinding wheels on the grinder

shaft to prevent wheel damage or acciden-tal separation.

Separation can result in fragments flying off the wheel at

high speeds.

5. USE ONLY WHEELS suitable for the speed of the

machine. Unsuitable grinding wheels can come apart,

throwing fragments out at high speeds.

6. USE ONLY WHEELS that have a bore exactly equal to

the arbors of the machine. Never attempt to machine

an undersized wheel to fit an arbor. Unsuitable grinding

wheels can come apart, throwing fragments out at high

speeds.

7. DO NOT OVERTIGHTEN WHEEL NUT.

8. DO NOT USE A WHEEL THAT VIBRATES. Dress the

grinding wheel, replace it, or replace the bearings of

the shaft. Unsuitable grinding wheels can come apart,

throwing fragments at high speeds.

9. INSPECT WHEELS before starting the machine for cracks

or fragments. REPLACE DAMAGED WHEELS immediately.

Parts of the wheel can be thrown at high speeds causing

serious injury.

10. ADJUST EYE SHIELDS close to the grinding wheel, and

re-adjust as the wheel wears down. Flying sparks are

dangerous and can cause fires or explosions.

11. ALWAYS MAKE SURE the eye shields are in place,

properly adjusted, and secured.

12. ADJUST TOOL RESTS close to the grinding wheel

(1/8" separation or less). Tighten the tool rest securely

to prevent shifting positions, and re-adjust as the wheel

wears down. The workpiece can be drawn into the wheel,

causing damage to the workpiece and/or serious injury.

13. STAND TO ONE SIDE before turning the machine "ON".

Loose fragments or wheel parts could fly from the wheel

at high speeds.

14. NEVER GRIND ON A COLD WHEEL. Run the grinder

for one full minute before applying the workpiece. A cold

wheel has a tendency to chip. Those fragments could fly

from the wheel at high speeds.

15. NEVER START THE MACHINE with the workpiece

against the grinding wheel. The workpiece can be drawn

into the wheel, causing damage to the machine and/or

serious injury.

16. CLEAN THE MACHINE thoroughly when processing

different types of workpieces (wood, steel, or aluminum).

Combining wood and metal dust can create an

explosion or fire hazard. DO NOT GRIND OR POLISH

MAGNESIUM. Fire will result.

17. NEVER GRIND NEAR FLAMMABLE GAS OR LIQUIDS.

Sparks can create a fire or an explosion.

18. AVOID AWKWARD OPERATIONS AND HAND

POSITIONS. A sudden slip could cause a hand to move

into the grinding wheel.

19. KEEP ARMS, HANDS, AND FINGERS away from the wheel.

The abrasive surfaces can cause serious injury.

20. HOLD THE WORKPIECE FIRMLY against the tool rest.

Loss of control of the workpiece can cause serious injury.

21. DRESS THE WHEEL on the face only. Dressing the side

of the wheel could cause it to become too thin for safe

use.

22. GRIND A WORKPIECE using the face of the grinding wheel

only. Loss of control of the workpiece can cause serious

injury.

23. NEVER APPLY COOLANT directly to the grinding wheel.

Coolant can weaken the bonding strength of the grinding

wheel and cause it to fail. Dip the workpiece in water to

cool it.

24. DO NOT TOUCH the ground portion of a workpiece until

it has cooled sufficiently. Grinding creates heat.

25. PROPERLY SUPPORT LONG OR WIDE WORK-

PIECES. Loss of control of the workpiece can cause

serious injury.

26. NEVER PERFORM LAYOUT, ASSEMBLY, or set-up work

on the table/work area when the machine is running. A

sudden slip could cause a hand to move into the wheel.

Severe injury can result.

27. TURN THE MACHINE "OFF", disconnect the machine

from the power source, and clean the table/work area

before leaving the machine. LOCK THE SWITCH IN THE

"OFF" POSITION to prevent unauthorized use. Someone

else might accidentally start the machine and cause

serious injury to themselves.

28. ADDITIONAL INFORMATION regarding the safe and

proper operation of power tools (i.e. a safety video)

is available from the Power Tool Institute, 1300

Sumner Avenue, Cleveland, OH 44115-2851 (www.

powertoolinstitute.com). Information is also available

from the National Safety Council, 1121 Spring Lake

Drive, Itasca, IL 60143-3201. Please refer to the

American National Standards Institute ANSI 01.1 Safety

Requirements for Woodworking Machines and the

U.S. Department of Labor OSHA 1910.213 Regulations.

Failure to follow these rules may result in serious personal injury.
