FOR
CORDS

22. CHILDPROOF THE WORKSHOP AREA by
removing switch keys, unpluggingtools from the
electrical receptacles, and using padlocks.

If you are using an extension cord outdoors, be sure
it is marked with the suffix "W-A" ("W" in Canada) to
indicate that it is acceptable for outdoor use.

23. DO NOT OPERATE TOOL IF UNDER THE
INFLUENCE OF DRUGS OR ALCOHOL.

Be sure your extension cord is properly sized, and in
good electricalcondition.Always replace a damaged
extension cord or have it repaired by a qualified person
before using it.

24. SECURE ALL WORK. When it is possible, use clamps
or jigs to secure the workpiece. This is safer than
attempting to hold the workpiece with your hands.

Protect your extension cords from sharp objects,
excessive heat, and damp or wet areas.

25. USE A PROPER EXTENSION CORD IN GOOD
CONDITION. When using an extension cord, be sure
to use one heavy enough to carry the current your
product will draw. The table below shows the correct
size to use depending on cord length and nameplate
amperage rating. If in doubt, use the next heavier
gauge.

120 VOLT OPERATION ONLY

The smaller the gauge number, the larger diameter of
the extension cord. If in doubt of the proper size of an
extension cord, use a shorter and thicker cord. An
undersized cord will cause a drop in line voltage result-

This tool is equipped with an electric cord that has an
equipment grounding conductor and a grounding plug.
The plug MUST be plugged into a matching electrical
receptacle that is properly installed and grounded in
accordance with ALL local codes and ordinances.

SPECIFIC SAFETY INSTRUCTIONS
FOR BENCH GRINDERS
The operation of any grinder can result in debris being
thrown into your eyes, which can result in severe eye
damage. ALWAYS Wear Safety Goggles (that comply
with ANSI standard Z87.1) when operating the grinder,
Safety Goggles are available at Sears Retail Stores. Keep
your thumbs and fingers away from the grinding wheels.

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 the both sides of the gdnding
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, verify that the grinding
wheel has a higher R.P.M. rating than the maximum
R.P.M. of the Bench Grinder.

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 untilthe grinder comes up to full
speed. There is always a possibility that debris from
a damaged grindingwheel may be discharged
towards the operator.
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.
NEVER

FORCE THE WORKPIECE

AGAINST

GRINDING WHEEL, especially if the wheel is cold.
Apply the workpieca slowly, allowing the grinding
wheel an opportunity to warm up. This will minimize
the chance of wheel breakage. DO NOT gdnd 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.
