SERVICE & MAINTENANCE
CAUTION
Handle pressurized hydraulic uid carefully. Escaping
pressurized hydraulic uid can have sufcient force to
penetrate your skin causing serious injury. This uid
may also be hot enough to burn. Serious infection or
reactions can develop if proper medical treatment is
not administered immediately.
5.12 FILLING HYDRAULIC FLUID
Hydraulic systems contain uid under high pressure.
Never check for leaks with your hands. Relieve
pressure before disconnecting any hydraulic lines.
CAUTION
5.13 CHANGING HYDRAULIC OIL FILTER
HYDRAULIC
FILTER
Hydraulic uid drives the feed roller. Check the uid
level daily and ll as needed. The uid and lter should
be changed and system cleaned if the uid becomes
contaminated with foreign matter (water, dirt, grease, etc.)
or if the uid has been subjected to temperatures greater
than the maximum recommended.
The hydraulic pump requires premium hydraulic uids
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
uids meeting Allison C-3 or Caterpillar TO-2, and certain
specialty agricultural tractor uids.
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 reservoir 4.
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.
Change the hydraulic oil lter after the rst 50 hours of
operation and every 200 hours thereafter.
To change the hydraulic oil lter:
U s i n g a n o i l fi l t er w re n c h , t u rn t h e f i l t er 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.7.
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
WARNING
5.14 CHANGE OIL
Check the oil level before each use. Change oil as directed
in the engine owner's manual.
