SERVICE & MAINTENANCE
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.
WARNING
5.10 GREASING THE BEARINGS AND
PIVOTS
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.
The chipper models described in this manual have several
bearings and pivots that require greasing. Refer to pictures for
greasing intervals and quantities.
NOTE
Polyuria and lithium based greases are not compatible.
Mixing the two grease types may lead to premature failure.
The use of pneumatic grease equipment is not recommended
unless low pressure is assured.
NOTE
5.8 TRAILER SERVICE TIPS
Check wheel bolt torque every 8 hours of towing use.
Check air pressure in tire every 8 hours. Fill to the recom-
mended PSI located on the tire sidewall.
Check and repack wheel bearings with grease every year.
