SERVICE & MAINTENANCE

BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, REMOVE KEY,

DISCONNECT THE BATTERY CABLES AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

WARNING

5.7 HYDRAULIC FLUID RESERVOIR

The chipper is tested before shipping. In order to test the

equipment, the fluid levels are filled. However, before starting the
machine, check the hydraulic fluid level in the reserve tank.
Premium hydraulic fluids containing high quality rust, oxidation

and foam inhibitors are required. These include premium turbine

oils, API CD engine oils per SAE J183, M2C33F or G automatic

transmission fluids meeting Allison C-3 or Caterpillar TO-2, and

certain specialty agricultural tractor fluids.

5.8 CHANGING THE HYDRAULIC OIL

FILTER

Using an oil filter wrench turn the filter counterclockwise.
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 hydraulic

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.

5.9 TRAILER SERVICE TIPS

Check wheel bolt torque every 8 hours of towing use.
Check air pressure in tires every 50 hours. Fill to the recom-

mended PSI located on the tire sidewall.
Check and repack wheel bearings with grease every year.

5.6 REPLACE/CLEAN THE AIR FILTER

Refer to the engine owners manuals included with your machine

for specific instructions on replacing and cleaning the air filter.

NOTE

Polyuria and lithium based greases are not compatible.

Mixing the two grease types may lead to premature failure

of the chipper.

NOTE

The use of pneumatic grease equipment is not recommended

unless low pressure is assured.

5.10 GREASING BEARINGS

Mounted bearings are pre-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:

UANTITY

Frequency (50 hours)

Recommended

quantity of 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 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 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.
The chipper models described in this manual have several

bearings that require greasing. Refer to the next page for greasing

locations, intervals and quantities.
