Prerequisites and information on tilting
Before tilting the driver's cab, the following requirements must be met:
– The truck crane must be level.
– All loose objects must be removed from the driver's cab.
– The main boom is raised to the extent (about 1.5 m (4.9 ft)) that the
driver's cab will not touch the main boom (nor the hose drum) when
tilting!
– Ensure that the hook block is outside the driver's cab slewing range and
the windscreen.
S Risk of damage to the steering's universal joint
The steering wheel may only be moved when the driver's cab is lowered
and locked. When moving the steering wheel into other driver's cab
positions, the steering's universal joint can be damaged.
