regularly replace the hydraulic
oil
When a hydraulic breaker is used, the oil
deteriorates more quickly than that used for
a usual excavation operation. Be sure to
replace the hydraulic oil and the return filter
elements.
• Failure to replace these in time can lead to
damage to the machine and the breaker
hydraulic system. To prolong the service life
of the hydraulic devices, properly replace
the hydraulic oil and the return filter
elements according to the table below.
• When replacing the hydraulic oil, clean the
suction strainer.
