WORKING MODE 3
Working Mode
The mode selector switch can be used to switch the mode to match operating conditions and purpose, thereby
enabling work to be performed efficiently.
Make effective use of each mode as follows.
When the starting switch is turned to the ON position, the working mode is set to P mode (digging).
Use the working mode switch to set the mode to the most efficient mode to match the type of work.
Setting Economy Mode

sumption becomes, but the production is reduced accordingly.
