5.14 REMOVING THE ROTOR
5.15 CHANGE OIL
Lubricate the machine periodically with a lithium-based
grease. Extreme working conditions will require more
frequent greasing.
Grease the following points every 50-100 hours of
operating time:
● Engine side bearing
● Chute side bearing
Polyurea and lithium-based greases are not
compatible. Mixing the two grease types may lead to
premature failure.
WARNING
Figure 5.13, Chute Side Bearing Zerk
Figure 5.12, Engine Side Bearing Zerk (Bottom of Bearing)
Do not over grease bearings. Overlling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.

rotor shaft end cap on chute side of the machine.
2. Loosen the set screws on the lock collar securing the
