MACHINE READY FOR ATTACHMENT
ATTACHMENT OPERATIONS
WARNING
If the pedal is operated when the auto-deceleration is being actuated and the engine speed has dropped, the engine speed will
suddenly rise, so be careful when operating.
If you leave your foot resting on the pedal and depress the pedal by mistake, there is danger that the attachment may suddenly
move and cause serious personal injury. If you do not need to operate the pedal, do not rest your foot on the pedal.
When the attachment is not being used, set the lock pin of the pedal to the LOCK position to prevent the pedal from being
operated.
The method of operating the attachment is as follows.
When Using Breaker
NOTICE
When carrying out breaker operations, use the breaker mode. If the breaker mode is not used, the breaker may be damaged.
With the working mode set to B mode, insert the lock pin in
front-only FREE position (b). Press the front of the pedal to
operate the breaker.
1. Set the working mode to B mode.
When switching the working mode, see "Working Mode Selector Switch (PAGE 3-26)".
2.
When it is required to change the setting like a flow rate, see "Changing Breaker Mode Setting (PAGE 3-47)".
Precautions when using
Check that the stop valve is at the FREE position.
Check that the working mode is B mode.
For details of the path of the oil, see "HYDRAULIC CIRCUIT (PAGE 6-8)".
When considering whether it is necessary to install an accumulator for the attachment circuit, contact the
attachment manufacturer and then decide.
For other precautions when handling the breaker, follow the instruction manual from the breaker manufacturer
and use the breaker correctly.
The deterioration of the hydraulic oil when using the breaker is much faster than for normal operations, so reduce
the maintenance interval for the hydraulic oil and element.
For details, see "MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER (PAGE 4-17)".
