12.10 WORKING MODE SELECTION
WORKING MODE
The mode selector switches can be used to switch the mode to
match the conditions and purpose of work, thereby enabling efficient op-
eration.
Use the following procedures to make the most effective use of each
mode.
When the starting switch is turned ON, the working mode is set to
general operation mode (G.O.), so normal work can be carried out with-
out needing to set the mode.
Set the most effective mode according to the type of work using
working mode selector switch.
NOTICE
Never carry out breaker operation in heavy-duty operation
mode (H.O.) as this may result in breakage of hydraulic equipment.
