4. Continue this combination of flange movements
until the wobble is eliminated.
If required, a shim made of paper or card stock may
be placed between flange and wheel side.
Figure 10-3: wheel balancing
NOTE: Very slight wobble may still exist at spin-up
and spin-down, but will not affect normal speed
operation.
10.6 Dressing the wheel
Below is a general procedure for dressing a grinding
wheel.
Use safety glasses or face
shield during dressing operations.
1. Back off the tool rest enough to allow the
dresser to hook over its inside edge (Figure 10-
4). Tighten tool rest in position.
2. Turn on grinder and allow it to reach operating
speed.
3. Set the wheel dresser on the rest and bring it
into contact with the wheel by raising its handle.
Hold the dresser firmly.
Note: If sparks appear, increase the pressure
of the dresser discs against the wheel.
4. Move the dresser evenly left and right across
the wheel face until the wheel looks clean and
is square to the tool rest.
5. Remove the dresser, and adjust the tool rest to
1/16” away from the newly dressed wheel.

10.7 Wire wheel brushes
Wire brushing (not provided) is a fast way to remove
rust scale, burrs, and paint from metal. Use coarse
wire brushes for hard cleaning jobs. Use fine wire
brushes for polishing and finish work. When the
brush tips become dull, reverse the brush on the
grinder.
10.8 Cleaning
Metal shavings may still be hot
from recent grinding operations. Make sure
shavings and debris are cold before cleaning
the grinder. Use a brush or rag to clear shavings,
not bare hands.
Avoid use of the following
cleaning chemicals or solvents: gasoline,
carbon tetrachloride, chlorinated solvents,
ammonia and household detergents containing
ammonia.
Brush all shavings from the motor housing, tool rest,
wheel guards and sanding belt areas. Clean area
beneath grinder base.
Periodically use a cleaning stick (not provided)
against the abrasive belt to remove build-up.
If the abrasive belt becomes loaded, it can be
cleaned by soaking within a solvent. Allow to dry
completely before reinstalling.
10.9 Tension lever tightness
If sanding belt tension lever becomes loose, hold the
lock nut with an 11mm wrench, and tighten screw
with 5mm hex wrench (Figure 10-5). Lever should
be snug but still easily moved.

10.10 Lubrication
All motor and wheel bearings are permanently
lubricated and sealed at the factory and require no
additional lubrication.
10.11 Additional servicing
Any additional servicing on the grinder should be
performed by an authorized service representative.
