You can then release the button S47, and continue to operate the lock pin with the buttons L or R (holding function).

* Standard equipment; with other options of the "Rotate grapple" function (optional equipment), the operation can be carried out by means of the left or right joystick.

Releasing and locking:

The auxiliary function must be activated (switch 19, LED on).

Press and hold the button S47

The quick-coupling system is activated.

Press and hold the right button R

This symbol, together with a buzzer warning sound, indicates that the quick-coupling system is not properly locked.

3.5.3.5Attaching working tool

The working tool must be securely positioned on the ground or secured in a frame.

The working tool must be in such a position that the openings of the half shells face upwards or away from the machine. Switch off the magnet system (if installed).

Releasing and attaching working tool

Release the quick-change adapter. Release all buttons.

Move the industrial stick in such a way that the front side is inserted between the half shells of the suspension tackle.

If positioned correctly, the lock bolts are aligned with the bores of the grapple suspension.

Fig. 3-82 Locking

Lock the quick-change adapter. Release all buttons.

If in place: Loosen the locking screw 1 (optional equipment) at the suspension (unless the locking screw is loosened, the working tool cannot be moved freely).

Caution!

The hydraulic lines are under pressure.

Before connecting the hydraulic lines, depressurise them using the joystick (switch off diesel engine, turn ignition key to contact position, operate the joystick).

Connect the hydraulic or electrical lines as required (e.g. for the attachment of a grapple).

The safe mounting of the working tool must be checked with a proper visual inspection.

3.5.3.6Dismantling working tool

The working tool must be in a stable position.

If required, a support structure (frame) must be in place.

Danger!

After the working tool is released, it is fully disconnected from the machine. The working tool might become dislodged and cause serious injury.

Before releasing the quick-coupling system, place the working tool on the ground.

Switch off the magnet system (if installed).

Fully open the jaws of grapples.

Place the working tool without load on the ground, or on a suitable frame.

Fig. 3-83 Tightening the locking screw, disconnecting the lines and releasing

If in place: Tighten the locking screw 1 (optional equipment) at the suspension (without tightening the screw, the suspension would tilt to the side during removal, so that it would be difficult to ta ke it up at the next attachment).

Caution!

The hydraulic lines are under pressure.

Before disconnecting the hydraulic lines, depressurise them using the joystick (switch off diesel engine, turn ignition key to contact position, operate the joystick).

Disconnect all hydraulic or electrical lines to the working tool (e.g. for dismantling of grapple).

Release the quick-change adapter.

Release all buttons.

Move the industrial stick in such a way that the front side is removed from the half shells.

Attach the other working tool. - alternativelyTo switch off the buzzer, lock the quick-change adapter without attaching a working tool.

Installation and removal of attachment parts

3.5.3.7Acknowledging buzzer signal (warning signal)

After the working tool has been removed, the buzzer (warning signal) sounds as long as the system is not locked.

If the overload warning system is switched on, the warning buzzer can be acknowledged.

If no working tool is to be mounted, it is useful to deactivate the warning signal. This is also recommended to ensure that another buzzer sound (i.e. from the overload warning system) is actually audible.

Press the switch S349

The buzzer is switched off. The "quick-change adapter" icon remains displayed.

Note!

The acoustic warning signal is automatically reactivated when the system is locked again.

In order to activate the warning buzzer, lock the system once. The "quick-change adapter" icon on the screen disappears. The buzzer and warning sound are on at the next release process.

3.5.4LIKUFIX MH 110 quick-coupling system (optional equipment)

The LIKUFIX MH 110 quick-coupling system allows for the fast and efficient exchange of working tools without having to leave the operator's cab. Hydraulic and electrical connections are thereby automatically disconnected and connected.

carrying out an intended locking or release procedure, immediately shut down the machine. If these indicating elements are not on when you are carrying out an intended locking or release procedure, immediately stop the procedure. The alarm signals can be triggered if a lock pin has inadvertently become dislodged, or if a mechanical, hydraulic or electrical fault occurs. Only resume operation after the defective part has been repaired or replaced. stem is equipped with an integrated safety load hook for the safe attachment of lifting tackle, such as cables or chains. To use lifting tackle, you must use a suspension system with a safety load hook.

3.6General working methods

3.6.1Tips for the proper operation of the machine preventing damage and wear

In order to prolong the service life of the machine and to prevent avoidable damage, observe the following instructions: attachment is used to hammer against a hard material to remove it. Repeated impact of the working attachment against hard materials results in damage to the steel structure and the machine components.

tool are combined, there is a risk that the tool collides with the operator's cab. This can result in damage to the operator's cab, and the operator might suffer injury. r drilling material is not permitted.

with the attachment. If this happens by accident, slowly lower the machine back onto the ground. Do not lower the machine quickly onto the ground, and do not attempt to dampen this movement with the hydraulics, as this can damage the machine.

Caution!

Incorrect operation of the attachment (e.g. backhoe bucket, concrete crusher, scrap shear, hydraulic hammer, swivelling rotator, stick extension) might result in an excessive load of the attachment.

The load on the attachment is greatest fully retracted (in end position)

There is a risk of damage to parts of the equipment, to the hydraulic cylinders and to the machine.

Do not fully extend or retract the hydraulic cylinders.

When the hydraulic cylinders are near the end positions (limit range), move them only slowly and with great caution.

When swivelling the attachment, maintain a minimum distance of 10° to the end position to the tilt cylinder.
