ADDITIONAL SAFETY RULES FOR GRINDERS

1.

DO NOT OPERATE

your tool until it is completely assem-

bled and installed according to the instructions.

2.

IF YOU ARE NOT

thoroughly familiar with the oper-

ation of grinders, obtain advice from your supervisor,
instructor or other qualified person.

3.

USE

only grinding wheels rated for 3600 RPM with a

1/2" arbor hole. 

NEVER

use a wheel rated lower than

3600 RPM or 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 IMMEDIATE-

LY

.

5.

DO NOT

overtighten wheel nut.

6.

ALWAYS

maintain a distance of 1/8" or less between

the grinding wheel and the tool rest. Adjust the tool rests
as the grinding wheels decrease in size with use.

7.

SECURELY

tighten tool rests so they cannot shift

position while in use.

8.

NEVER

grind on a cold wheel. The grinder should

always be started and run at idle speed for one full
minute before applying work.

9.

NEVER 

grind on the side of the wheel. 

ALWAYS

grind on the face of the wheel only.

10.

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.

11.

SPARKS ARE A HAZARD! NEVER

grind near flam-

mable gas or liquids.

12.

ALWAYS MAKE SURE

the wheel guards and eye

shields are in place, properly adjusted and secured.

13.

KEEP

the spark guards close to the wheel and re-

adjust them as the wheel wears.

14.

MAKE CERTAIN

the blotter and wheel flanges furn-

ished are used to mount the grinding wheels onto the
grinder shaft.

15.

STAND

to one side of the wheel when turning on the

power.

16.

AVOID

awkward hand positions where a sudden slip

could cause a hand to move into the grinding wheel.

17.

ALWAYS

keep hands and fingers away from the

grinding wheel.

18.

NEVER

start the grinder with the workpiece pressed

against the grinding wheel.

19.

DRESS

the wheel on the face only. Dressing the side

of the wheel can cause it to become too thin for safe use.

20. 

DO NOT

use a wheel that vibrates. Dress the wheel,

replace the wheel, or replace the shaft bearings, if worn.

21.

GRINDING CREATES HEAT

. Do not touch the

workpiece until you are sure it has cooled sufficiently.

22.

REDUCE THE RISK

of unintentional starting. Move

switch to the 

“OFF”

position in the event of a power 

failure.

23.

ALWAYS

keep guards in place when using a wire

brush or buffing wheel in place of the standard grinding
wheel.

24.

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.

25.
