OPERATION AND MAINTENANCE
Hydraulic Maintenance
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
Landoll dealer.
3. Check all hydraulic hoses weekly. Look for binding or
cracking. Replace all worn or defective parts
immediately.
IMPORTANT
Lower the unit to the ground, and relieve hydraulic
pressure before attempting to service any hydraulic
component.
4. Transport locks are provided to hold the implement in
a raised position. 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 4-10 on how to purge the hydraulic systems.
