OPERATION

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 if the button (2) is
depressed, the breaker is actuated.
1. Set the working mode to B mode.
2. When menu select switch (5) 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 (12).
3. The monitor screen changes to screen (B), so if it is neces-
sary to make fine adjustment, press up switch (14) or down
switch (13) to move the bar graph showing the oil flow up or
down, then press input confirmation switch (12).
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 (12).
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.
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.

(240)".
