ADDITIONAL SAFETY RULES FOR GRINDERS
1.
DO NOT OPERATE
your tool until it is completely
assembled 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 attachments rated for 3600 RPM or higher
with a 1/2" arbor hole.
NEVER
use an attachment rated
lower than 3600 RPM or attempt to machine an
undersized attachment to fit an arbor.
4.
NEVER
use a chipped or cracked wheel.
ALWAYS
inspect each wheel before mounting on the grinder.
REPLACE A CRACKED WHEEL IMMEDIATELY
.
5.
DO NOT
overtighten wheel nut.
6.
ALWAYS
maintain a distance of 1/8" or less between
the wheel and the tool rest. Adjust the tool rests as the
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
operate tool near
flammable 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 flanges furn-
ished with the grinder are used to mount the
attachments (grinding wheels, wire brushes, buffing
wheels, etc.) onto the shaft.
15.
STAND
to one side of the grinder when turning on
the power.
16.
AVOID
awkward hand positions where a sudden slip
could cause a hand to move into the attachment
(grinding wheel, wire brush, buffing wheel, etc.).
17.
ALWAYS
keep hands and fingers away from the
attachments (grinding wheel, wire brush, buffing wheel,
etc.).
18.
NEVER
start the grinder with the workpiece pressed
against the attachment (grinding wheel, wire brush,
buffing wheel, etc.).
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 an attachment that causes vibration.
Dress the grinding wheel, replace the wheel or other
attachment, or replace the shaft bearings, if worn.
21.
GRINDING CREATES HEAT
. Do not touch the
work-piece until you are sure it has cooled sufficiently.
22.
SHOULD
any part of your tool be missing, damaged,
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.
23.
