WHEN USING BREAKER
Depress the switch (2) of the right control lever to operate the
breaker.
Set the working mode to the B (breaker mode) mode.
NOTICE
Do not use the heavy-duty operation mode for breaker
operations. If the breaker is used in the heavy-duty operation
mode there is danger that the hydraulic equipment may be
damaged.
Precautions when using
Check that the stopper valve is in the OPEN position.
●
Consult with the attachment maker to decide whether it is
●
necessary to install an accumulator for the attachment circuit.
For details of other precautions when handling the breaker,
●
read and use correctly the instruction manual provided by the
breaker manufacturer.
The deterioration of the hydraulic oil when using the breaker
●
is much faster than normal operations, so reduce the mainte-
nance interval for the hydraulic oil and element.
