The following section is designed to give instructions on
the basic operations of this bench grinder. However, it
is in no way comprehensive of every grinder application.
It is strongly recommended that you read books, trade
magazines or get formal training to maximize the potential
of your bench grinder and to minimize the risks.
BASIC PRECAUTIONS
WARNING
• ALWAYS WEAR EYE PROTECTION! Hot sparks are
produced during grinding operations.
6
• Never sharpen or grind anything made of aluminum,
brass, or copper.
• To avoid serious injury, never grind on the sides of the
grinding wheels.
CAUTION
• Keep all bystanders a safe distance away from the tool
and not in direct line, front or back of the grinder.
• Prolonged grinding will cause most materials to become
hot. Use care when handling such materials.
STARTING AND STOPPING THE
GRINDER
The "ON / OFF" switch has a removable plastic switch
key. With the key removed from the switch, unauthorized
and hazardous use by children and others is minimized.
• To turn the grinder "ON", insert the plastic switch key
into the slot of the switch and move the switch to the
"ON" position.
• To turn the grinder "OFF", move the switch to the "OFF"
position.
• To lock the switch in the "OFF" position, grasp the end
of the switch key and pull it out.
• With the switch key removed the switch will not operate.
NOTE: If the switch key is removed while the grinder is
running, it can be turned "OFF" but cannot be restarted
without inserting the switch key.
CAUTION
Always lock the switch "OFF" when the grinder is not in
use. Remove the key and keep it in a safe place. In the
event of a power failure, blown fuse or tripped circuit
breaker, turn the switch "OFF" and remove the key,
preventing an accidental startup when the power comes
on.
OPERATION
BASIC OPERATION
The bench grinder is designed for hand held grinding,
sharpening, and cleaning operations.
Grinders remove material rapidly so pressure is the key to
efficient grinding.
• Plug the power cord to a suitable power source.
• Stand to the side of the bench grinder and turn it "ON"
by moving the "ON / OFF" switch to the "ON" position.
• Allow the grinding wheels to come up to a steady speed
for at least one minute before starting to grind.
• Place the workpiece on the appropriate tool rest for the
desired operation.
• Move the workpiece towards the grinding wheel until
it lightly touches. Move the workpiece back and forth
across the front surface of the grinding wheel removing
the desired amount of material.
IMPORTANT: Never force the workpiece against the
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.
• To turn off grinder, move the power switch to the "OFF"
position. Unplug the power cord from the power source.
SHARPENING DRILL BITS
• To use the drill bit sharpening tool rest, lay the drill
bit flat in the "V" groove. Firmly hold on to the drill bit
shank. Slide the drill bit towards the grinding wheel until
it lightly touches. Keep the drill bit flat to the grinding
wheel and rotate drill bit
• The operator may place the hot end of the workpiece
into water in a quench tray to cool it.
• After completing the grinding operations, move the
power switch to the "OFF" position.
CAUTION
It will take a few minutes for the grinding wheels to come
to a complete stop.
• Unplug the power cord from the power source.
