Warning
mounted bearings are pre-lubricated at our factory and are
ready for operation.
relubricaTion: Relubrication of bearings is determined
by operating conditions and environment. Relubricate
standard bearings with a lithium based grease.
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 operating conditions. The
quantities shown in the pictures are recommended
amounts. In most cases, it is best to lube 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
overfilling. Overfilling can lead to excessive heat and or
unseating of the seals. Grease should be introduced in
small increments and under light pressure. Whenever
possible, the bearing should be rotated slowly while grease
is being added to ensure equal distribution throughout the
raceways.
Check wheel bolt torque every 8 hours of towing
use.
Check air pressure in tire every 8 hours. Fill to the
recommended pSI located on the tire sidewall.
Check and repack wheel bearings with grease every
year.

Warning
Before inspecting or servicing any part of this machine,
shut off power source, disconnect spark plug wire from
spark plug and make sure all moving parts have come
to a complete stop.
The chipper models described in this manual have several
bearings and pivots that require greasing. Refer to Figures
31 and 32 for greasing intervals and quantities.
