MAINTENANCE
7-33
Change Hydraulic Oil and Replace Full-Flow Filter
Element
Hydraulic breaker operation subjects the hydraulic system
to become contaminated faster and to quickly deteriorate
the hydraulic oil.
Failure to adhere to proper maintenance intervals may
result in damage to the base machine and the breaker.
In order to extend the service life particularly of the
hydraulic pump, change the hydraulic oil and the full-flow
filter element at the specified frequency given below.
(Refer to the "Hydraulic System" in the "MAINTEMANCE"
chapter.)
Changing intervals differ depending on the brand. (Refer to
the "Hydraulic System")
