1.
Take down the grabber completely by using the joystick.
2.
Turn off the engine.
3.
Unscrew the lever screws of the limit switch.
4.

stroke. The
chains shall not be loose.

that the arm is not fully retracted or that the gripper is open or closed. This may cause
accidents, injuries and/or property damage.
Caution!
This procedure must be done correctly before adjusting the gripper auto-closing system.
