FILLING HYDRAULIC FLUID
Hydraulic fluid drives the feed roller. Check the fluid
level daily and fill as required. 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 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.
In the unlikely event that the oil is completely drained
from the hydraulic system, oil must be added and any
air must be purged from the system. To do this:
1. Clean all system components (reservoir, fittings,
etc.).

2. Fill the hydraulic reservoir.
3. 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.
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 is purged from the
unit. Refill reservoir 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 pump is now ready for
operation.
