MAINTENANCE

Lubrication

The machine is completely lubricated. The bearings and

gears in the gear unit have enough lubricant for approxi-

mately six months of normal operation. All other bearings

are sealed and have enough lubricant for the life of the ma-

chine. 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 ﬁ gure 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 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 Clarke 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 ﬂ ow out the vent

hole. If none appears it may be necessary to add ad-

ditional 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 ﬁ gure 10.

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 ﬁ gure 11.

3. To replace the brushes, disconnect the ﬁ eld wire

(A) from the brush holder (B). Then remove the two

screws and washers (C) securing the holder to the

motor housing. See ﬁ gure 12.
