ADDITIONAL SAFETY RULES FOR
GRINDERS
1 . DO NOT OPERATE THIS MACHINE until it is
assembled and installed according to the
instructions.
2. OBTAIN ADVICE FROM YOUR SUPERVISOR,
instructor, or another qualified person
if you are
not familiar with the operation of this machine.
3. FOLLOW ALL WIRING CODES and recommended
electrical connections.
4. USE THE GUARDS WHENEVER POSSIBLE.
Check to see that they are in place, secured, and
working correctly.
5. ALWAYS USE THE BLOTTER (furnished) and wheel
flanges to mount the grinding wheels on the grinder
shaft.
6. USE ONLY GRINDING WHEELS suitable for the
speed of the machine.
7. USE ONLY GRINDING WHEELS that have a bore
exactly equal to the arbors of the machine. Never
attempt to machine an undersized wheel to fit an
arbor.
8. DO NOT USE A GRINDING WHEEL THAT
VIBRATES.
Dress the grinding wheel, replace it, or
replace the bearings of the shaft.
9. INSPECT GRINDING WHEELS BEFORE START-
ING THE MACHINE
for cracks or chips. REPLACE
DAMAGED GRINDING WHEELS immediately.
10. ADJUST SPARK GUARDS close to the grinding
wheel, and re-adjust as the wheel wears down.
11. ADJUST TOOL RESTS close to the grinding wheel
(1/8" (3.8mm) separation or less). Tighten the tool
rest securely to prevent shifting positions.
12. STAND TO ONE SIDE before turning the machine
“ON”.
13. NEVER GRIND ON A COLD GRINDING WHEEL.
Run the grinder at idle speed for one full minute
before applying the workpiece.
14. NEVER START THE MACHINE with the workpiece
against the grinding wheel.
15. NEVER GRIND NEAR FLAMMABLE GAS OR
LIQUIDS.
Sparks can create a fire or an explosion.
16. AVOID AWKWARD OPERATIONS AND HAND
POSITIONS
where a sudden slip could cause a
hand to move into the grinding wheel.
17. KEEP ARMS, HANDS, AND FINGERS away from
the grinding wheel.
18. HOLD WORK FIRMLY against the tool rests.
19. DRESS THE GRINDING WHEEL on the face only.
Dressing the side of the grinding wheel could cause
it to become too thin for safe use.
20. GRIND A WORKPIECE using the face of the
grinding wheel only.
21. 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.
22. DO NOT TOUCH the ground portion of a workpiece
until it has cooled sufficiently. Grinding creates heat.
23. TURN THE MACHINE “OFF” AND DISCONNECT
THE MACHINE
from the power source before
installing or removing accessories, before adjusting
or changing set-ups, or when making repairs.
24.. TURN THE MACHINE “OFF”, disconnect the
machine from the power source, and clean the
table/work area before leaving the machine. If your
machine has a switch lock-out feature, LOCK THE
SWITCH IN THE “OFF” POSITION to prevent
unauthorized use.
