2 Assembly
Your Chipper may arrive totally or partially assembled. If your machine arrives partially assembled, you may need to perform
the steps in this section.
2.1 ADDING MOTOR OIL TO ENGINE (ALL MODELS)
IMPORTANT
Motor oil should be
checked before the chip-
per is started. Add if
necessary.
1. The machine was shipped with oil
in the engine, as it was tested at
the factory.
2. To determine which type of oil to use,
refer to the engine owners manual
included in the owners kit of the
chipper.
3. Remove the oil fill plug.
4. Checking as necessary, add oil to
the motor until the dipstick shows
the correct reading.
2.2 ADDING HYDRAULIC FLUID
Hydraulic fluid is used to drive the feed
roller. The hydraulic pump is attached
to the motor (diesel models) or
connected to the motor with a belt
(gasoline models).
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.
If system has no oil, follow this startup
procedure:
1. Before starting the hydraulic pump,
make sure all system components
(reservoir, fittings, etc.) are clean.

2. Fill the reservoir with recommended
hydraulic fluid, which should be fil-
tered before entering the reservoir.
3. The inlet line leading from the reser-
voir to the pump must be filled be-
fore start-up. Loosen the fitting at
the pump on this inlet line until oil
bleeds out.
4. Start the engine and run at the low-
est possible RPM.
6. As air is purged from the unit, the
oil level in the reservoir will drop and
bubbles may appear in the fluid.
Refill the reservoir as necessary.
7. Run the feed roller in both directions
for several minutes until any remain-
ing air is purged from the unit. Refill
the reservoir as necessary.
8. Shut down the engine, check for and
correct any fluid leaks, and check
the reservoir level. Add fluid if nec-
essary. The hydraulic gear pump is
now ready for operation.
