Motor Brush Inspection and
Replacement
Be sure tool is unplugged before inspecting brushes. Brushes should
be regularly inspected for wear. To inspect brushes, unscrew the two
end cap screws and remove end cap (see Figure 13). To remove each
brush, first unplug the shunt wire terminal connection. Then carefully
back the brush spring out of the brush box and remove brush (see
Figure 13). Brushes should slide freely in brush box. If brushes are
worn down to .3" (see Figure 14) they should be replaced. To reinstall
each brush carefully back the spring out of the brush box, insert the
brush and return the spring making sure it is pressing on the brush
and not touching the brush box. Then replace the end cap and two
screws.
Operation Tips for More Accurate Cuts
• Allow the wheel to do the cutting. Excessive force will cause the
wheel to glaze reducing cutting efficiency and/or to deflect caus-
ing inaccurate cuts.
• Adjust fence angle (Figure 7).
• Make sure material is laying flat across base.
• Properly clamp material to avoid movement and vibration.
Cleaning
Blowing dust and grit out of the main housing by means of an air hose
is recommended and may be done as often as dirt is seen collecting in
and around the air vents.

Gears should be relubricated every 60 to 90 days, depending upon
use. This lubrication should only be attempted by experienced power
tool repair persons like the mechanics at GRABBER service centers.
The gear case should be wiped clean and 1/2 oz. (16 grams) of
