Maintenance
CAUTION : Maintenance and repairs performed
by unauthorized personnel could result in damage
or injury. Maintenance and repairs performed by
unauthorized personnel will void your warranty.
Failure to perform maintenance at recommended
intervals may void warranty.
Carbon Brushes
Inspect all four brushes every 6 months or 250 hours.
Access to the brushes is gained through the front and
back motor vent plugs and under both motor covers
(Figure 7). Press tab (A) on spring clip assembly in,
rotate, then remove (Figure 8).Use needle-nose pliers to
disconnect the shunt wire. If any brush has worn to 3/8”
in length or shorter, replace the entire set.
CAUTION : Use only motor brush PN 40818A or PN
40055A with shunt wire or motor failure will occur.
When replacing the brushes make sure that the brush
seats against the commutator, the spring rest in the
recess of the brush, and the brush is free to travel.
When returning the switch cover, keep any wires clear of
the commutator and any pinch site.
Gearbox Lubricant
To change the lubricant in the gearbox, follow this
procedure:
1. Put the machine upside down on a bench.
2. Align one of the two holes in the rubber pad with
one of the three holes in the rotating wall guard.
3. Align both holes with one of the three screws in the
gear housing cover. Remove the screw from the
gear housing cover. (Figure 9)
4. Align the holes with each of the other two screws,
then remove screws.
CAUTION : Make sure no dust enters the gear box.
Damage will occur to the gear box.
5. Remove the cover from the gear housing.
6. Remove the old lubricant from the gearbox.
7. Add six ounces of American Sanders Technology

CAUTION : To prevent damage to the motor, do not
add more than six ounces of lubricant to the gearbox.
8. Using the three screws removed above, install the
cover on the gear housing.

small amount of excess lubricant should flow out
the vent hole. If none appears it may be necessary
to add additional lubricant.
