Adjusting inner shut-off point (MIN):
Move the boom upwards.
Retract the industrial stick all the way to the desired shut-off point (MIN).
Switch off the diesel engine and push the safety lever upwards.
Loosen the screws 1
Move the connecting link 2 until the outer edge enters the stress field of the limit switch 3
Tighten the screws 1
Check the stick cylinder shut-off function.
If necessary, repeat the adjustment and check the settings again.
Adjusting outer shut-off point (MAX):
To adjust the settings for a limited forward working range, lower the boom so that the attachment is positioned close to the ground.
Extend the industrial stick all the way to the desired shut-off point (MAX).
Switch off the diesel engine and push the safety lever upwards.
Loosen the screws 1.
Move the connecting link 2 until the outer edge enters the stress field of the limit switch 3
Tighten the screws 1
Check the stick cylinder shut-off function. If necessary, repeat the adjustment and check the settings again.

Danger!
Risk of injury!
Never let anybody move the attachment (e.g. grapple) by hand.
Installation and removal of attachment parts
Press the switch S19. Auxiliary function is activated. The LED in the switch is on. Press and hold the button L The attachment turns (swivels) to the left. The locking bolts are extended. Press and hold the button R The attachment turns (swivels) to the right. The locking bolts are retracted.

3.5.2Attachment of grapple to industrial stick
Danger! Risk of injury!
Ensure that the machine operator follows the hand signal instructions of the instructor when moving the equipment.
Two workers are required to attach or remove the grapple.
3.5.2.1Attaching grapple
Before attaching a clamshell grab or multiple grab, ensure that the necessary hydraulic lines for grapple operation are mounted on the stick.
The grapple must be in a stable position (grabs fully opened).
Move the attachment in order to position the industrial stick between the bearing points of the grapple suspension 1
Insert the bolts 2 and secure them with the plate 3
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 and press the buttons of the "Rotate grapple" function).
Move the safety lever up.
Connect the hydraulic hoses 4 and 5 (for the supply of the grab cylinders) to the pipelines.
For grapples with hydraulic rotator, also connect the hydraulic hoses 6 and 7 to the pipelines for this auxiliary equipment.
Complete all working movements several times without load (opening and closing grapple, moving grapple to the right and left) in order to let any trapped air escape from the hydraulic circuits.
3.5.2.2Removing grapple
Fully open the grabs and place the grapple in a vertical position on level ground.
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 and press the buttons of the "Rotate grapple" function).
Move the safety lever up.
Disconnect the hydraulic hoses from the pipelines on the stick. Immediately seal open lines to prevent dirt from entering the system.
Prop up the grapple to ensure that it cannot topple over.
Unscrew the plate 3 and carefully drive out the bolt 2. To do this, you might have to start the diesel engine and lift the attachment slightly from the ground.
3.5.3Industrial stick with hydraulic quick-change adapter (optional equipment)
The industrial stick with hydraulic quick-change adapter allows for the fast and easy exchange of working tools.
3.5.3.1Safety information

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 locking 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.

3.5.3.2Positioning option
Working tools that are prone to tilting or cannot be placed on the ground must be secured. For attachment and removal use suitable equipment (e.g. frames, etc.).
