Test new wheels for cracks and maintain the
existing sequence of retaining hardware. Be sure
the grinder is unplugged before attempting repairs.
To change a wheel (refer to Figure 5):
1. Disconnect grinder from power source.
2. Move spark guard and tool rest away from the
wheel.
3. Remove the guard cover using a Phillips or
flathead screwdriver.
4. Stabilize the wheel by holding the opposite
wheel firmly.
5. Unscrew the arbor nut with a 1" wrench.
Note
: Turn the locking nut on the right-hand
wheel counterclockwise to loosen. Turn the
locking nut on the left-hand wheel clockwise to
loosen.
6. Remove the outer flange and wheel.
7. Clean flanges. Check the flanges to make sure
they are flat. Wheel flanges that are not flat will
cause the wheel to wobble.
8. Install the inner flange, wheel, outer flange,
and nut on the arbor. Tighten the nut.
Do not
over tighten
– this may cause the wheel to
crack, or the flanges to bend.
9. Replace the guard cover. Adjust spark guards
and tool rests to 1/16" clearance from wheel.

Cleaning
Metal shavings may still be hot
from recent grinding operations. Make sure
shavings and debris are cold before cleaning
the grinder.
Brush all shavings from the motor housing, tool
rests, and wheel guards.
Check grinding wheels for cracks and chips.
Replace if damaged.
Avoid the use of the following
cleaning chemicals or solvents: gasoline,
carbon tetrachloride, chlorinated solvents,
ammonia and household detergents containing
ammonia.

Lubrication
All motor bearings are permanently lubricated by
the manufacturer and require no additional
lubrication.
