• Is the selector valve in the dirt cover set to the position for
the breaker?
• Is lock bar (2) for the selector valve in the dirt cover instal-
led to the position for the breaker?
• Do you replace the hydraulic oil and its filter element at intervals shorter than the standard?
The deterioration of the hydraulic oil when using the breaker is much faster than in the normal operations,
so check the maintenance time with “MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER (4-11)”.
When considering whether it is necessary to install an accumulator for the attachment circuit, contact the
attachment manufacturer and then decide.
When handling the breaker, follow the instruction manual from the breaker manufacturer and use the break-
er correctly.
