Hydraulic Maintenance
IMPORTANT
Lower the unit to the ground, and relieve hydraulic
pressure before attempting to service any hydraulic
component.
WARNING
Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands (See
Figure 4-5.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.

1. Check the tractor hydraulic fluid level per tractor
owner's manual and after any leakage. Check fluid
level with the cylinders in the retracted position.
2. If a cylinder or valve leaks, disassemble the parts to
determine the cause of the leak. Any time a cylinder
is opened up, or whenever any seal replacement is
necessary, it is advisable to clean all parts and
replace all seals. Seal kits are available from your
Brillion dealer.
3. Check all hydraulic hoses weekly. Look for binding or
cracking. Replace all worn or defective parts
immediately.
4. Transport locks are provided to hold the implement in
a raised position. See Figure 3-4. Do not attempt to
perform any service work under the implement
without first installing the transport locks. Before
servicing any hydraulic component, lower the
implement to the ground and relieve all system
pressure. If a hydraulic component is disconnected,
repaired, or replaced, it will be necessary to purge the
system of air before operation. See "Hydraulic Lift
System" on page 3-6.

Firming Roller
IMPORTANT
Always replace worn or damaged Firming Roller
Rubber Press Wheels.
The Firming Roller rotates as one roller. The individual
Rubber Press Wheel typically don't rotate independently.
After an initial run of 5-10 hours, check Firming Roller to
ensure that on each end of the Firming Roller the Bolts are
tight at a full torque of 55 Ft-Lbs. If not tighten the Bolts
evenly on both ends to a final torque of 55 Ft-Lbs.
Thereafter check Firming Roller annually. See
Figure 4-6.
Check Firming Roller for worn or damaged Rubber Press
Wheels and replace. When replacing the Rubber Press
Wheels, the distance on both ends from the Firming Roller
End Plate to the end of the Firming Roller Shaft should be
equal. See Figure 4-7.
