5.12 HYDrauliC feeD mainTenanCe
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.
The diesel engine is tested before shipping. In order to test
the equipment the fluid levels are filled. However, before
starting the machine, and every time the engine is started
thereafter, be sure to check the coolant level. If the level
is low, add fluid.
Refer to the engine owner’s manual for coolant information
and maintenance.
Change the hydraulic oil filter after the first 50 hours of
operation and every 200 hours thereafter.
To change the hydraulic oil filter:
using an oil filter wrench, turn the filter 1.
counterclockwise.
Once the filter becomes loose, turn it out the rest of the
2.
way with your hand.
Properly discard old filter.
3.
lube the rubber seal on the new filter (PN 16922) with 4.
clean hydraulic oil.
Install the filter onto the threaded pipe. Turn with your
5.
hand until the filter is finger tight.
using an oil filter wrench, tighten the filter another ½
6.
turn.
Check hydraulic oil level and fill if necessary.

Check wheel bolt torque monthly. 1.
Check air pressure in tires monthly. 2.
Check and repack wheel bearings with grease every 3.
12 months.
When towing, always connect the safety chains. Make
4.
sure trailer hitch bolts are tight.
Check trailer lights periodically.
