Hydraulic Oil and Filter Service Intervals
When using a hydraulic breaker, the viscosity breakdown and
contamination of hydraulic oil is faster because the work
condition is more severe than during normal digging work. To
prevent the hydraulic components (especially pump) from
having a shortened life cycle, replace the hydraulic oil and main
hydraulic oil return filter using the following schedule.
NOTE:
The replacement intervals of hydraulic oil and filter
depend upon the amount of time the hydraulic
breaker is being used. These intervals should be
followed as opposed to regularly scheduled
maintenance.

oil and filter are used. If any other
brands are used, the guaranteed changed interval should be reduced in half.
