Damage to switch bar.
► Protect the switch bar against impact stress.

Tools required:

•

Hex socket key

•

Open-ended wrench

•

Slotted screwdriver

Carry out the following steps:

Release the electrical connection (plug) from the proximity switch in the
lantern.

Undo screws (39) with the inner hex socket key.

Remove snap rings (15) from the control top (B).

Remove the compressed air connections (Y2+Y3) on the lifting actuator.

Pull the control top (B) upwards.
