AUTO-DIGGING SWITCH
Keep the auto-digging switch off when other attachments than a bucket are installed.
If you perform the operation without turning off the auto-digging switch, the work equipment may move
unexpectedly, and this may lead to serious personal injury or death.
• Keep the auto-digging switch off during other works than digging work.
• If the kickdown switch is pressed and the gear is shifted to FORWARD 1st while the auto-digging
switch is set to ON, the mode becomes the auto-digging mode, and the boom may rise automatical-
ly or the bucket may tilt automatically.
• Keep the auto-digging switch off during dozing work. If the auto-digging switch has been set to ON
before the work, the auto-digging may start.
The auto-digging switch is used to turn on and off the auto-dig-
ging.
Each time position (A) of the switch is pressed, the function
switches between ON and OFF.
If you release your hand from the switch, it automatically re-
turns to its original position.
