Control and operation
Installation and removal of attachment parts
To lock 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).
Detaching a work tool
To move the equipment into position:
Caution!
Hydraulic lines are pressurized!
Remove the pressure using the joystick before removing the hydraulic lines (switch off the engine, turn the ignition key into the contact position, operate the joystick).
Disconnect hydraulic lines or electrical lines, if necessary (eg. when dismounting a grab).
Extend the shovel tilting cylinder fully.
To unlock the quick-change adapter:
Danger!
Risk of injury.
Once unlocked, there is no fixed connection between the adapter and the work tool. The work tool could work itself out independently.
Ensure that the work equipment cannot be moved by others when this action is being carried out.
Always keep the work tool as close to the ground as possible when unlocking to avoid creating conditions which may lead to danger.
Approach the quick-change adapter from the side and unscrew the locking screw 2 using the crank 3 from the locking pin 1
Insert the crank 3 in the locking pin 1 and turn to the left (anti-clockwise), until both locking pins 1 are inserted as far at the stop.
To put down the work tool:
Installation and removal of attachment parts
Slowly insert the shovel tilting cylinder and lay the work tool on the ground. The new work tool can be taken up.
Using the quick-change adapter for hoisting work
The quick-change adapter has two integrated lifting hooks. The machine may only be used for hoisting work if the safety devices required for the purpose are present and functioning correctly (see chapter "Hoi
The maximum load carrying capacity of each individual lifting hook is given on the quick-change adapter. The load carrying capacity of the quick-change adapter or the integrated lifting hook can exceed or fall short of the load carrying capacity of the carrier device.
When operating, it should be ensured that the values for the carrier device / quickchange adapter given in the load chart and the technical data are adhered to.
Load hoisting work can be carried out with attached or dismounted work tools. With dismounted work tools, it is sensible to fully insert the locking pins when carrying out hoisting work. This prevents the load take-up device being turned round too strongly by the locking pins and damaged.
Danger!
Never use the take-up hook 6 to fasten a load because there is no secure hold for the load take-up device, eg. rope or chains, in the take-up hook.
Fasten the load on the lifting hook as

Safety information
the working area of the equipment when attaching or dismounting work tools. Move the work equipment as slowly as possible when attaching and dismounting a work tool.
Familiarize yourself with the mode of operation of the quick-change adapter without attached work tools if possible.
adapter is monitored by a visual and acoustic warning device (buzzer and telltale light). The function of the warning device should be checked daily by operating the quick-change adapter.
tivated without a deliberate locking or unlocking procedure being carried out, stop all work at once. If the buzzer and telltale light are not activated while a deliberate locking or unlocking procedure is being carried out, stop all work at once.
This could be caused by an unmonitored position change of the locking pins due to mechanical or hydraulic damage. A defect may also be present in the electrical system (eg. proximity switch or buzzer).
Only resume working once defective parts have been repaired or replaced.
purpose is pressed.
Always keep the work tool as close to the ground as possible when unlocking to avoid creating conditions which may lead to danger. Only activate the quickchange adapter to carry out a deliberate locking or unlocking procedure.
locking pins for the quick-change adapter insert in the bore holes on the work tool which are designed for the purpose and that the work tool raises correctly. A direct visual check must be made to ensure that the work tool is correctly positioned. with the work tool ,where the work tool is only raised to the point where the correct position of, for example, the pin in the pin eye can be tested by tilting in and out.
hook can exceed or fall short of the load carrying capacity of the carrier device. When operating, it should be ensured that the values provided in the load chart and the technical data for the carrier device are adhered to.
