Installation and removal of attachment parts

To lock the quick-change adapter:

Fig. 3-114 Locking the quick-change adapter Danger! Before locking, there is no fixed connection between the work tool and the quickchange adapter. The work tool could under certain circumstances fall out and injure people. Approach the quick-change adapter with the utmost care. Push the safety lever up to secure the work equipment against unintentional movement. No work movements can be carried out when pilot control devices, eg. the joystick or foot pedals, are operated. Insert the crank 3 in the locking pin 1 and turn to the right (clockwise), until both locking pins 1 are extended as far as the stop. The work tool is bolted on when taking up normally. Screw the locking screw 2 into the locking pin. Danger! An incorrectly locked quick-change adapter could open when operating! Ensure that the locking pins are always locked by the sealing plug 4 on the one side and by the locking screw 2 on the other side. Check daily to ensure that the locking screw 2 is correctly positioned.

Caution! Hydraulic lines are pressurized! Remove the pressure using the joystick before connecting the hydraulic lines (switch off the engine, turn the ignition key into the contact position, operate the joystick). Connect hydraulic lines or electrical lines, if necessary (eg. when attaching a grab).
