Hydraulic Breaker Maintenance
Interval
Hydraulic oil breaks down faster on machines equipped
with a hydraulic breaker than on machines equipped with
a bucket.
Change the hydraulic oil and filters every 400 hours on
breaker-equipped machines.
NOTICE!
The hydraulic oil filter must be replaced after 250
hours with a breaker operating rate above 50%.
See “Replace the Hydraulic Oil” on page 5-35.
After Maintenance is Completed
Record the completion of all of the maintenance tasks in
the Maintenance Log. If authorized, remove all
lockout/tagout warnings and machine-securing elements
and fully activate the machine. Return the machine to
operation.
