Do not over grease bearings. Overfilling 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.
NoTE
Polyurea and lithium-based greases are not compatible.
Mixing the two grease types may lead to premature failure.
ImpoRTaNT
lubricate the machine periodically with a lithium-based
grease. Extreme working conditions will require more
frequent greasing.
grease the following points every 50 hours of operating
time: Two are located on the bearing assembly (one on
each side of the chipper). Two are accessed by opening
the hood of the chipper. One zerk is on the discharge chute
base (see pictures below).
