6.17 Hammer-Breaker Maintenance
Notice!
Hammer Breaker
– The operation of hydraulic hammer breaker will accelerate the pollution
and deterioration of hydraulic oil. Therefore, in comparison with the
machine with a bucket, require to replace the hydraulic oil and hydraulic
oil tank filter frequently, otherwise the hammer breaker, hydraulic oil
pump and other components of hydraulic system may be damaged, and
adopt the following recommended replacement intervals.

Notice
Change periods of hydraulic oil and filter element - Follow the advice:
– The change periods of the hydraulic oil and/or its filter element depend on the
hydraulic knapper’s duration and intensity of use. These change intervals
usually coincide with the regular maintenance intervals.
– When using the hydraulic knapper, the hydraulic oil will be contaminated
rapidly. Its viscosity will drop faster since the operating condition is more
stressful for the system than for digging.
– Refer to the table below to change hydraulic oil and replace the filter element.
It will help to avoid shortening the lifespan of hydraulic parts due to the
hydraulic oil contamination (especially in the main pump).
