SAVE THESE INSTRUCTIONS.
Refer to them often and use them to instruct others.
ADDITIONAL SAFETY RULES
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
accidental 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.

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.
