Hydraulic fluid drives the feed roller. The hydraulic pump
is direct or belt driven from the engine or disk rotor.
The hydraulic pump requires premium hydraulic fluids
containing high quality rust, oxidation, and foam inhibi-
tors. 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:
Clean all system components (reservoir, fittings, etc.)
before starting the hydraulic pump.
after filtering the hydraulic fluid, fill the hydraulic res-
ervoir.
Fill the inlet line leading from the reservoir to the pump
before start-up. loosen the fitting at the pump on this
inlet line until oil bleeds out.
Start the engine and run at the lowest possible RPM.
as you purge air from the unit, the oil level in the res-
ervoir will drop and bubbles may appear in the fluid.
Refill the reservoir as necessary.
Run the feed roller in both directions for several min-
utes until any remaining air purges from the unit. Refill
the reservoir as necessary.
Shut down the engine, check for and correct any fluid
leaks, and check the reservoir level. add fluid if neces-
sary. the hydraulic pump is now ready for operation.
