CHECK POINTS WHEN USING BREAKER
• Is the stop valve in FREE position?
• Is the working mode set to B mode?
For the oil passage route, see “METHOD FOR CHANGE-OVER AND CONNECT HYDRAULIC CIRCUIT
FOR MACHINE READY FOR INSTALLATION OF ATTACHMENT (6-18)”.
• 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 SCHEDULE (4-12)”.
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.
