OPERATION
The motor is designed for operation within 10 percent above or below the voltage specified on the
nameplate. Running the unit on voltages outside that range may cause the motor to overheat and
burn out. Heavy loads require a voltage at the motor terminals equal to the voltage specified on
the nameplate.
ON/OFF ROCKER SWITCH
A single rocker switch controls the power supply to the grinder. Push the switch up to turn on the
grinder. The switch will lock in place. Push it down to turn off the power.
The rocker switch has a removable yellow key. Remove the key from the switch to prevent power
from reaching the motor. The rocker switch won't function or lock into place without the key.
VARIABLE SPEED SWITCH
The bench grinder has an infinite variable speed from a low of 2,000 RPM to a top speed of 3,450
RPM. The speed is controlled by a knob on the front of the bench grinder.
1. Turn the control knob counterclockwise to increase speed.
2. Turn the control knob clockwise to decrease speed.
GRINDING
WARNING! Never start the tool with the operator or bystander in line with the grinding wheel. A
damaged grinding wheel could shatter and the debris may cause an injury.
•
Sharpening and grinding operations can be done with the two grinding wheels.
•
Use the tool rest to support the workpiece during grinding when possible.
•
Keep a steady, moderate pressure on the workpiece and keep it moving at an even pace for
smooth grinding.
•
Do not force the tool. It will work most efficiently at the rate for which it was designed.
Pressing too hard overheats the motor and prematurely wears down the grinding wheel.
•
The grinding wheel should rotate into the object being sharpened.
•
As wheels wear, the tool rests should be positioned closer to the face of the wheels. The gap
between the wheel and the tool rest should not be greater than 1/16 in. When the wheels are
worn to the extent that the 1/16 in. maximum gap cannot be maintained. The wheels should
be replaced.
•
Note the original beveled angle on the item to be sharpened. Try to maintain that angle.
Sharpening a cutting edge requires removing burrs from the edge.
•
Deburring the edge is done best by using the grinder to pull burrs from the edge across the
bevel angle.
•
Use a slower wheel speed when sharpening tempered tools. Overheating will destroy
the temper.
•
Dip the workpiece into a coolant regularly to prevent overheating. Overheating can
weaken metals.
•
Do not grind using the sides of a grinding wheel unless it is specifically designed for
that purpose.
