2 Assembly
Your Chipper may arrive totally or partially assembled. If
your machine arrives partially assembled, perform the steps
in this section.
2.1 ADDING MOTOR OIL TO ENGINE
(ALL MODELS)
IMPORTANT
Check motor oil before
starting the chipper. Add
if necessary.
1. The machine’s engine ships filled with oil from factory
testing.
2. Refer to the engine owners manual to determine oil type
used.
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 drives the feed roller. The hydraulic pump is
attached to the motor (diesel models) or connected to the
motor with a belt (gasoline models).
The hydraulic pump requires premium hydraulic fluids
containing high quality rust, oxidation, and foam inhibitors.
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. Clean all system components (reservoir, fittings, etc.)
before starting the hydraulic pump.
2. After filtering the hydraulic fluid, fill the hydraulic reser-
voir.
3. Fill the inlet line leading from the reservoir to the pump 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 lowest possible RPM.
5. As you purge air from the unit, the oil level in the reservoir
will drop and bubbles may appear in the fluid. Refill the
reservoir as necessary.
6. Run the feed roller in both directions for several minutes
until any remaining air purges from the unit. Refill the reser-
voir as necessary.
7. Shut down the engine, check for and correct any fluid leaks,
and check the reservoir level. Add fluid if necessary. The
hydraulic gear pump is now ready for operation.
