or lay on your skin may promote absorption
of harmful material. Always use properly
fitting
NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure,
and wash exposed areas with soap and water.
26.
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 on page 8 shows the correct size to use
depending on cord length and nameplate
amperage rating. If in doubt, use the next
heavier gauge.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
resulting in a loss of power and overheating.

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 permanent eye
damage.
ALWAYS WEAR EYE PROTECTION. Everyday
eyeglasses 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 EYE SHIELDS 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 WORK PIECE AGAINST
A GRINDING WHEEL,
especially if the wheel
is cold. Apply the work piece 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.
SAFETY GUIDELINES
