WarninG
The hydraulic oil filter should be changed every 250 hours
of operation. To do this:
using an oil filter wrench turn the filter as indicated
below.
Once the filter becomes loose, turn it out the rest of
the way with your hand.
properly discard old filter.
Lube the rubber seal on the new filter with clean hy-
draulic oil.
Install the filter onto the threaded pipe. Turn by hand
until the filter is finger tight.
using an oil filter wrench, tighten the filter another
1/2 turn.
Check hydraulic oil level and fill if necessary.

Check wheel bolt torque every 8 hours of towing
use.
Check air pressure in tires every 50 hours. Fill to the
recommended pSI located on the tire sidewall.
Check and repack wheel bearings with grease every
year.

polyuria and lithium based greases are not compatible.
Mixing the two grease types may lead to premature
failure of the chipper.
The use of pneumatic grease equipment is not
recommended unless low pressure is assured.
Mounted bearings are lubricated at our factory and are
ready for operation.
relubriCation
Relubrication of bearings is determined by operating
conditions 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
The quantities shown on the next page are recommended
amounts. Experience will show correct fill amounts due
to wide variances in applications, greasing equipment and
operating conditions. 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
overfilling. Overfilling can lead to excessive heat and/or
unseating 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.
