Service Schedules
Service Intervals for Hydraulic Oil and Filters when using a Breaker
When using a breaker, contamination and degradation of the hydraulic oil occurs much more quickly than in normal excavating
use. If the machine is used with increasingly degrading oil it can cause problems in the control valve, premature wear of the
hydraulic pump and damage to the hydraulic system as a whole.
Servicing of the hydraulic oil and filters must be done more frequently according to the percentage of total operating hours
involving use of the breaker. When a breaker is fitted, ensure that the oil and filters are changed at the intervals shown in the
table below.
The hydraulic oil must be sampled and checked for contamination and degradation at the intervals shown.
