The replacement interval with

is applied for the excavators on which the hammer breaker is used
continuously for a long time. For the excavators on which the hammer breaker is relatively less, the
replacement interval can be prolonged as following chart.
(2) The filter element should be replaced when the hammer breaker is operated continuously for more than
100 hours.
7.4.6 KEY POINTS FOR HYDRAULIC CLAMP BREAKER
Consult your designated distributor to select a clamp
breaker with correct size and weight for the excavator.
Clamp breaker is much heavier than the bucket, thus, the
excavator should be operated slowly to avoid tipping. Following
notes should be observed.
(1) Don’t operate the clamp breaker when the bucket cylinder is fully extended or retracted to
avoid the damage of the excavator.
(2) Don’t rotate upper-structure to one side of the excavator to operate the clamp breaker. To
avoid tipping, always crush in the front or rear of the machine.
(3) Always operate the clamp breaker on flat ground and never on slopes.
(4) It’s forbidden to transport fragments with the clamp breaker.
(5) The hydraulic system may be polluted and go bad quicker if installing the clamp breaker instead
of the bucket too frequently. Thus, the replacement for hydraulic filters and hydraulic oil should be
more frequently than the usual excavation to avoid the damage of hydraulic pump and other
hydraulic components. The replacement interval, please refer to the “Key Points of Hydraulic
Hammer Breaker Operation”.
(6) When transporting the excavator, the clamp breaker should be dismantled and hydraulic pipes
should be capped and plugged.
