WORKING MODE

Working Mode
The mode selector switch can be used to switch the mode to match the operating conditions and purpose, thereby
enabling work to be carried out efficiently.
Make effective use of each mode as follows.
When the starting switch is turned ON, the working mode is set to the most commonly used general operation mode,
so normal operations can be carried out without setting the mode.
Use the working mode switch to set the mode to the most efficient
mode to match the type of work.
Working mode
DH mode Powerful digging and loading for short time in quarry
H mode Normal digging and loading operations
G mode Leveling, finishing operations, hauling operations
NOTICE
Do not carry out breaker operations in the DH mode. There is danger
that the hydraulic equipment may be damaged.
One-touch power max.
The digging power can be increased by operating the one-touch power
max. switch during operation. Make effective use of this function by
combining it with the working mode as necessary.
If the left knob switch is pressed once (single click) and kept pressed,
it is actuated as long as the switch is being pressed. The increase in
power is automatically stopped after 8.5 seconds.
