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.
