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.
(Refer to the “Hydraulic System” in the “MAINTENANCE”
Chapter.)
Replacement intervals differ depending on the brand of
hydraulic oil used. Refer to the Hydraulic System in the
MAINTENANCE Chapter.
Use the high performance element (micro-glass) on excavators
engaged in demolition and logging work.
f
NOTE: Full-flow filter restriction indicator is optional. If a
filter-paper element is used, this indicator does not operate.
(Refer to the "Hydraulic System" in the "MAINTENANCE"
Section.)
