Cabin tilt (RRE Ergo) during servicing
During servicing, the cabin must always be tilted so that its centre of
gravity passes the centre of rotation; the cabin will then drop gently into
its end position, which is the service position.
Warning!
Risk for personnel injuries, crushing.
The hydraulics does not stop the tilt motion beyond the balancing
point.
Make sure that the area that will house a tilted cab is free from person-
nel and objects prior to the commencement of tilt motion.
To raise the the cabin up out of the service position, the pump is started
and Q21 is activated.
Cabin tilt in the event of hydraulic or electrical pow-
er loss
If required, the cabin can be tilted up with a traverse, without the valve
being activated. However, in such a case Q21 must be activated, once
the cabin is to be tilted back. On the magnetic tube to Q21 there is an
allen screw, the emergency lowering screw, which allows opening of
Q21 in the event of the electronics being out of action.
