HYDRAULIC BREAKER, HYDRAULIC CRUSHER AND QUICK COUPLER
OPTIONAL ATTACHMENTS AND DEVICES
Change Hydraulic Oil and Replace Full-Flow Filter
Element
Hydraulic breaker operation results in faster contamination of
the hydraulic system, and faster deterioration of hydraulic oil.
Failure to comply with proper maintenance intervals may
result in damage to the base machine and the breaker.
Change the hydraulic oil and the full-flow filter element in
order to extend the service life particularly of the hydraulic
pump. (Refer to the section “Hydraulic System” in the
“MAINTENANCE” chapter.)
Change 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.

NOTE: Hydraulic oil filter restriction alam indicator is
optional. If a filter-paper element is used, this indicator does
not operate. (Refer to the section "Hydraulic System" in the
"MAINTENANCE" chapter.)
