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)
