5.12 FILLING HYDRauLIC FLuID
5.13 aIR FILTER (DIESEL SHoWN)
Both the diesel and the gas engines used on the 6” chipper
have air filters. Refer to the engine owner's manual
included with your machine for specific instructions on
replacing and cleaning these filters.
Hydraulic fluid drives the feed roller. Check the fluid
level daily and fill as needed. The fluid and filter should
be changed and system cleaned if the fluid becomes
contaminated with foreign matter (water, dirt, grease, etc.)
or if the fluid has been subjected to temperatures greater
than the maximum recommended.
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.
In the unlikely event that the oil is completely drained
from the hydraulic system, oil must be added and any air
bubbles must be purged from the system. To do this:
Clean all system components (reservoir, fittings, 1.
etc.).
Fill the hydraulic reservoir.
2.
Start the engine and run at the lowest possible RPM. 3.
As you purge air from the unit, the oil level in the 4.
reservoir will drop and bubbles may appear in the fluid.
Refill the reservoir as necessary.
Run the feed roller in both directions for several minutes
5.
until any remaining air purges from the unit. Refill the
reservoir as necessary.
Shut down the engine, check for and correct any
6.
fluid leaks, and check the reservoir level. Add fluid
if necessary. The hydraulic pump is now ready for
operation.
5.11 aDJuSTING THE CHIppER aNvIL
lift rotor access cover and expose rotor. 1.
Measure the amount of clearance between chipping 2.
blade and chipper anvil from inside of housing.
Loosen the three 1/2 inch bolts that hold the chipper
3.
anvil to the frame (see below).
Adjust inward or outward to the desired measurement, 4.
using the adjustment nuts provided.
Tighten bolts on chipping block to 75 ft-lbs. and resume
5.
operation.
If chipper anvil edge is damaged or worn unevenly, remove
the three bolts holding the anvil and use one of the other
three edges. Replace as necessary.
Adjustment
Nuts
The chipping blades should clear the anvil by 1/16 inch to
1/8 inch. Check the clearance every 8 hours of operation
and adjust if needed. The chipping anvil is reversible. All
four sides of the anvil can be used for chipping.
To adjust the anvil:
