Service Intervals for Hydraulic Oil and Filters when using a Breaker or Crusher
When using a breaker or crusher, 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 or crusher. When a breaker or crusher 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.

number of hours the machine has worked.
