When using a hydraulic breaker, the oil
deteriorates quicker than during normal
digging. Be sure to replace the hydraulic oil
and return filter element.
¡Failure to replace these in time can lead
to damage to the machine and breaker’s
hydraulic systems. In order to improve the
service life of the hydraulic systems, be
sure to replace the hydraulic oil and return
filter element according to the following
chart of the replacement interval.
¡Clean the suction strainer when changing
the return filter element.
