Operation
Preliminary Safety Check:
Before starting the grinder, with the power cord unplugged, and the Power Switch turned to the OFF
(“O”) position, check to ensure:
a) The safety shield is in place and properly adjusted.
b) The grinding stone can be revolved freely by hand.
c) The Tool Rest is in place, adjusted to within 3mm of the face of the grinding stone, and firmly
tightened in place.
Basic Operation:
1) With the power cord unplugged, and the Power Switch (6) turned OFF,
fill the water container 1/2 full.
2) Adjust the Tool Rest (31) to the desired angle. (See Tool Rest
Adjustment section on next page.)
3) Plug into an appropriate, circuit breaker protected 110/120 volt DC power outlet.
4) Press the Power Switch (6) to either “ 1” (forward) or ” 1” (reverse) positions, as required.
5) Allow the machine to run up to speed, and stay there for at least 30 seconds before beginning work.
If the grinder does not run smoothly, refer to the section on page 8 on Grinding Wheel care. Be sure
the Grinding Wheel is properly dressed and balanced before beginning work. Be sure the Grinding
Wheel is running at full speed before beginning work.
6) Feed the workpiece smoothly into the Grinding Wheel (22). Do not apply heavy pressure or bump
the workpiece against the Grinding Wheel. Apply light pressure on the work piece. Try to allow the
Grinding Wheel to continue to turn at full speed as you work.
WARNING: Do not use this grinder over 30 minutes each hour, or longer than 20 minutes
continuously. This will help prevent overheating of the grinder, and extend grinder life.
7) When done sharpening, move the Power Switch (6) to the OFF position. Allow the Grinding Wheel
to come to a stop on its own. Do not manually stop the Grinding Wheel by grabbing it or holding an
object against it. Stopping the Grinding Wheel causes stress and possible damage to the gears and
belts.
