ADDITIONAL SAFETY RULES FOR GRINDERS
1. WARNING: Do not operate your grinder until it is
completely assembled and installed according to the
instructions.
2. IF YOU ARE NOT thoroughly familiar with the
operation of grinders, obtain advice from your supervisor,
instructor or other qualified person.
3. ALWAYS use grinding wheels that have a bore
exactly equal to the arbor of the grinder. NEVER attempt
to machine an undersize wheel to fit an arbor.
4. NEVER use a chipped or cracked grinding wheel.
ALWAYS inspect each wheel before mounting on the
grinder. Replace a cracked wheel immediately.
5. ALWAYS maintain a distance of 1/8² or less
between the grinding wheel and the tool rest. Adjust the
tool rests as the grinding wheels decrease in size with
use.
6. SECURELY tighten tool rests so they cannot shift
position while in use.
7. NEVER grind on a cold wheel. The grinder should
always be started and run at idle speed for one full
minute before applying work.
8. NEVER grind on the side of the wheel. ALWAYS
grind on the face of the wheel only.
9. NEVER apply coolant directly to a grinding
wheel. Coolant can weaken the bonding strength of the
wheel and cause it to fail. Dip the workpiece into water to
cool it.
10. SPARKS ARE A HAZARD! NEVER grind near
flammable gas or liquids.
11. ALWAYS MAKE SURE the wheel guards and eye
shields are in place, properly adjusted and secured.
12. KEEP the spark guards close to the wheel and
re-adjust them as the wheel wears.
13. MAKE CERTAIN the blotter and wheel flanges
are used to mount the grinding wheels onto the grinder
shaft.
14. STAND to one side of the wheel when turning on
the power.
15. AVOID awkward hand positions where a sudden slip
could cause a hand to move into the grinding wheel.
16. ALWAYS keep hands and fingers away from the
grinding wheel.
17. NEVER start the grinder with the workpiece pressed
against the grinding wheel.
18. DRESS the wheel on the face only. Dressing the side
of the wheel can cause it to become too thin for safe use.
19. DO NOT use a wheel that vibrates. Dress the wheel,
replace the wheel, or replace the shaft bearings, if worn.
20. GRINDING CREATES HEAT. Do not touch the work-
piece until you are sure it has cooled sufficiently.
21. ALWAYS use grinding wheels that are suitable for
the speed of the grinder. NEVER use a wheel that is rated
lower than the grinder speed.
22. ALWAYS keep guards in place when using a wire
brush or buffing wheel in place of the standard grinding
wheel.
23. SHOULD any part of your grinder be missing, dam-
aged, or fail in any way, or any electrical component fail to
perform properly, shut off switch and remove plug from
power supply outlet. Replace missing, damaged or failed
parts before resuming operation.
24. THE USE of attachments and accessories not rec-
ommended by Delta may result in the risk of injuries.
25. ADDITIONAL information regarding the safe and
proper operation of this product is available from the
National Safety Council, 1121 Spring Lake Drive, Itasca, IL

26. SAVE THESE INSTRUCTIONS. Refer to them often
and use them to instruct others.
