SERVICE AND MAINTENANCE
NOTE
Polyuria and lithium based greases are not compatible.
Mixing the two grease types may lead to premature fail-
ure of the chipper.
NOTE
The use of pneumatic grease equipment is not recom-
mended unless low pressure is assured.
5.9 GREASEABLE BEARINGS
Mounted bearings are pre-lubricated at our factory and
are ready for operation.
RELUBRICATION:
Relubrication of bearings is determined by operating condi-
tions and environment. Lubricate standard bearings with a
LITHIUM based grease. Greasing intervals and quantities
are shown on the next page using the following symbol:
GREASING INTERVALS:
Bearings in extreme environments will require more frequent
greasing intervals.
GREASE FILL AMOUNTS:
It is preferred that experience dictate fill amounts due to
wide variances in applications, greasing equipment and op-
erating conditions. The quantities shown on the next page
are recommended amounts. In most cases, it is best to
lubricate in small amounts, under low pressure, until a thin
bead of fresh grease is visible at the seal lip area.
Care should be taken when greasing bearings to avoid over-
filling. Overfilling can lead to excessive heat and/or unseat-
ing of the seals. Grease should be introduced in small
amounts and under light pressure. Whenever possible, the
bearing should be rotated slowly while grease is added to
ensure equal distribution throughout the raceways.
The chipper models described in this manual have several
greaseable bearings that require greasing. Refer to the Fig-
ures 5.5 through 5.8 on the next page for greasing loca-
tions, intervals and quantities.
