Lubrication
The machine is completely lubricated. The bearings and gears in the gear
unit have enough lubricant for approximately six months of normal operation.
All other bearings are sealed and have enough lubricant for the life of the
machine. No lubricant is needed for the rotating disc guard.
How To Change The Lubricant In The Gearbox
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 disc guard.
3. Align both holes with one of the three screws in the gear housing
cover. Remove the screw from the gear housing cover. See figure
12.
4. Align the holes with each of the other two screws, then remove
screws.
CAUTION!
Make sure no dust enters the gear box. Damage could occur to
the gear box.
5. Remove the cover from the gear housing.
6. Remove the old lubricant from the gearbox.
7. Add ten ounces of American Sanders lubricant to the gearbox.
CAUTION!
To prevent damage to the motor, do not add more than ten
ounces of lubricant to the gearbox.
8. Using the three screws removed above, install the cover on the
gear housing.
9. Start the machine and let it run for 15 minutes. A small amount of
excess lubricant should flow out the vent hole. If none appears it
may be necessary to add additional lubricant.
10. Wipe off excess lubricant and clear vent hole.
How To Check The Carbon Brushes
Depending on use, a set of brushes can be expected to last 250 hours
and should be inspected sometime prior to that time.
To check the brushes, follow this procedure:
1. Remove the motor cover. See figure 13.
2. Inspect the carbon brushes. Replace both brushes if either brush
has worn to 3/8" in length, or is worn to the wear indicator. See
figure 14.
3. To replace the brushes, disconnect the field wire (A) from the
brush holder (B). Then remove the two screws and washers (C)
securing the holder to the motor housing. See figure 15.
