OPERATION
WARNING
●
Be careful when pressing the switch in the deceleration
range. The engine speed will rise suddenly.
●
Do not press the switch except when operating the
attachment. If the switch is depressed by accident, the
attachment may move suddenly and cause serious dam-
age or injury.
The operation of the attachment is as follows.
When the B mode control switch is ON and the lock pin position
makes only the front of the pedal free, if the front of the pedal is
depressed, the breaker is actuated.
1. Set the working mode to B mode.
2. When select switch (1) on the monitor is pressed, the screen
changes to screen (A). Select a suitable oil flow for the
breaker from among 140 litres/min, 100 litres/min, and 60
litres/min, then press input confirmation switch (2).
3. The monitor screen changes to screen (B), so if it is neces-
sary to make fine adjustment, press up switch (3) or down
switch (4) to move the bar graph showing the oil flow up or
down, then press input confirmation switch (2).
●
It is possible to change the oil flow in segments of approx. 10
litres/min.
●
If fine adjustment is not necessary, simply press input confir-
mation switch (2).
●
The default setting is 140 litres/min.
●
Even if the starting switch is turned OFF, the set oil flow when
the engine is next started will be the value set by the above
procedure.
Precautions when using
● Check that the stop valve is at the FREE position.
●
Check that the selector valve is in the position for using the
breaker and check that working mode is in B mode.
●
When considering whether it is necessary to install an accu-
mulator 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.
