Lift legs, general
4 1 1
The lift legs are designed to lift objects at the lower edge by gripping
around the object with four legs. To facilitate loading and transport
the front and rear legs can be controlled separately.
The lift legs are controlled with three switches on the instrument
panel.
The lift legs are raised and lowered in a pre-set sequence that is con-
trolled by the machine's control system (sequence is reversed when
3 2 3
raising). The legs' position (step in sequence) can be checked from
the diagnostic menu, see section 8 Control system, group 8.4.11.1
Combi, menu 14.
Operating position
Operating position is a predefined position of the rear lift legs that
gives the load correct centre of gravity if the machine is driven up to
the load with the rear legs lowered until alignment is obtained on the
rear legs. If the front legs are lowered and clamped around the load
in this position, the load's centre of gravity is centred so that the load
is not tilted when lifting. On the condition that the load has an even
weight distribution.
The function lift legs includes the following components.
