SAFETY INSTRUCTIONS
SPECIFIC SAFETY
INSTRUCTIONS FOR BENCH
GRINDERS
The operation of any grinder or power tool
can result in debris being thrown into your
eyes, which can result in severe and per-
manent eye damage. ALWAYS WEAR EYE
PROTECTION. Everyday eyeglasse are NOT
safety glasses. ALWAYS wear Safety Goggles
(that comply with ANSI standard Z87.1) when
operating power tools.
Basic precautions should always be followed
when using your bench grinder. To reduce the
risk of injury, electrical shock, or fire, comply
with the safety rules listed below:
1. ALWAYS USE THE EYESHIELDS AND
WHEEL GUARDS provided with the grinder.
2. REPLACE A CRACKED OR DAMAGED
GRINDING WHEEL IMMEDIATELY. A
damaged wheel can discharge debris at a
high velocity towards the operator. Carefully
handle the grinding wheels since they are
abrasive. Prior to replacing a grinding wheel,
check it for cracks. DO NOT remove the
blotter or label on both sides of the grinding
wheel. Tighten the spindle nut just enough to
hold the grinding wheel firmly to the Bench
Grinder. DO NOT over-tighten the nut.
Excessive clamping force can damage the
grinding wheel. Only use the wheel flanges
provided with the grinder. When selecting a
replacement grinding wheel use only properly
sized wheels, and verify that the grinding
wheel has a higher R.P.M. rating than the
maximum R.P.M. of the Bench Grinder.
3. THE DIAMETER OF THE GRINDING
WHEELS WILL DECREASE WITH USE.
Adjust the tool rests and spark arrestors to
maintain a distance of 1/16” from the wheel.
4. DO NOT STAND IN FRONT OF THE
BENCH GRINDER WHEN STARTING IT.
Stand to one side of the Bench Grinder and
turn it “ON”. Wait at the side for one minute
until the grinder comes up to full speed. There
is always a possibility that debris from a
damaged grinding wheel may be discharged
towards the operator.
5. THE BENCH GRINDER WILL PRODUCE
SPARKS AND DEBRIS DURING GRINDING
OPERATIONS. Be sure that there are not any
flammable materials in the vicinity. Frequently
clean grinding dust from the back of the
Bench Grinder.
6. NEVER FORCE THE WORKPIECE
AGAINST A GRINDING WHEEL, especially
if the wheel is cold. Apply the workpiece
slowly, allowing the grinding wheel an
opportunity to warm up. This will minimize
the chance of wheel breakage. DO NOT grind
using the sides of the grinding wheels. DO
NOT apply coolant directly to the grinding
wheel.
7. KEEP ALL WHEEL GUARDS IN PLACE.
DO NOT USE THE BENCH GRINDER WITH
THE WHEEL GUARDS REMOVED.
8. KEEP THE TOOL RESTS FIRMLY IN
PLACE AND TIGHTENED. Use them to
safely position your material for grinding.
9. ALWAYS USE THE SUPPLIED WHEEL
DRESSER TO RESURFACE THE FACE OF
THE GRINDING WHEEL.
10. DRESS THE GRINDING WHEEL
OFTEN. This will keep the wheel surface flat
and free of nicks and residue/glaze.
11. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are
removed from grinder before turning it on.
12. ALLOW THE GRINDER TO ATTAIN
FULL SPEED BEFORE BEGINNING WORK.
13. NEVER STOP THE GRINDER BY
FORCING MATERIAL INTO THE WHEEL.
Let the grinder stop rotating on its own.
14. SECURE THE BENCH GRINDER to a
stand or workbench to prevent sliding or
tipping during use. See page 12.
15. FREQUENTLY clean grinding dust from
inside of the wheel guards and beneath
grinder.
16. NEVER GRIND SMALL STOCK without
it being properly supported on the tool rests,
and held by pliers or clamps.
