Danger! - Unexpected actions on the machine.
Effect: Danger to life or serious injuries.
• Only persons who are confident with the machine may perform emergency manual
activation.
• The person performing the activation must know which machine parts are affected by
controlling the valves.
• The manipulation of the valves must only be carried out from a safe position outside the
range of the machine parts which are moved by the actuators.
• Ensure that no persons, animals or objects are within this danger zone.

To perform a function (for example raising/lowering the roller chute) the correct valves
must be activated. For the valves to be switched, see diagram (Comfort hydraulic block).
The following section contains a description of an example based on the Comfort
version.
12.14.1 Raising / Lowering the roller chute
• Screw in the starwheel screw on valve (Y03, Y04) 'roller chute'.
To raise:
• Using a pointed object, press in the magnetic plunger of valve (Y1) 'Control valve' and
keep it pressed in.
To lower:
• Using a pointed object, press in the magnetic plunger of valve (Y2) 'Control valve' and
keep it pressed in.
Note
After emergency manual activation has been executed, the knurled head screws for emergency
manual activation must be completely screwed out again!
Note
For lifting operations (cutting system / parking jack / roller chute) the control valve must be kept
pressed in after the function is executed until the knurled head screws have been completely
screwed out to release the valves.
