BREAKER MAINTENANCE
Change Hydraulic Oil and Replace Hydraulic Oil Tank Filter
Hydraulic breaker operation subjects the hydraulic system to
become contaminated faster and to deteriorate the hydraulic
oil quickly. For this reason, hydraulic oil must be changed and
the hydraulic oil tank filter and breaker-circuit oil filter must
be replaced more often than the machine attached with a
bucket. Failure to do so may result in damage to the breaker,
hydraulic oil pump, and other hydraulic system components.
Recommended changing intervals are shown below. (For
filter replacement and oil changing procedures, refer to the
“Hydraulic System” in the “MAINTENANCE” Section.)

NOTE: * The above figures are for 100% breaker time share.
When the breaker time share is less, changing
intervals can be extended as shown in the diagram
below.
Be sure to replace elements when breaker has been
operated for 100 hours continuously.
