LUBRICATION
All motor bearings are permanently lubricated at the
factory and require no additional lubrication.
CLEANING
WARNING:
For your own safety, turn the switch "OFF"
and remove the plug from the power source outlet before doing
any maintenance.
1. Brush all shavings from the motor housing, tool
rests, and wheel guards.
2. Check grinding wheels for cracks and chips,
replace if damaged.
CAUTION:
Metal shavings may still be hot from recent
grinding operations. Make sure shavings and debris are cold
before cleaning the grinder.
3. Use liquid dishwashing detergent and water to
clean the eye shields.
Note: Certain cleaning chemicals can damage plastic parts.
4. Avoid the use of the following cleaning chemicals
or solvents: gasoline, carbon tetrachloride,
chlorinated solvents, ammonia and household
detergents containing ammonia.
WARNING:
All electrical or mechanical repairs should
be attempted only a trained repair technician. Use only identical
replacement parts. Any other parts may create a hazard.
USING DRESSING WHEEL (NOT SUPPLIED)
(Figure 10)
Grinding wheels tend to fill up (with the material you
are grinding), get dull, and lose their shape. The
dressing wheel is the one remedy for all three of
these conditions.
1. Adjust the tool rests (1) to a horizontal position.
2. Turn on the grinder, making sure to follow all
safety precautions.
3. Firmly place fingers in the recessed gripping slots
and support the dressing wheel on the tool rest,
making sure that the dressing tool (2) makes
contact with the grinding wheel at a position just
below the center point of the grinding wheel
surface.
4. Move the dressing wheel across the wheel face
to remove material and restore the wheel surface.
