Boom self-levelling
Self-levelling is a system that
keeps the attachment tilted in
same position when lifting or
lowering the boom.
Self-levelling is an automatic
hydraulic system. There is a
levelling cylinder on the left side
of the boom which follows the
movements of the loader boom
and keeps the attachment level.
NOTE: Self-levelling is disabled
when the boom floating is
switched on.
When the attachment tilt is turned
to either extreme position, the
boom lift cylinder will have to work
against the pressure of the self
levelling cylinder.
To prevent extreme stresses to the
loader boom, operate the bucket
tilt control to move out from
extreme tilt before lifting or
lowering the boom.
Self levelling is disabled when the
boom floating is switched on.
Boom can't be pushed down with
hydraulic force, when floating is on.
Use boom floating only when
necessary.
.
Boom floating (option)
The boom floating is a system that allows an
attachment to follow the surface of the ground. The
floating system releases the lift cylinder and allows it
to float upwards from the position where it is when
boom floating is switched on. When boom floating is
switched on, it is not possible to push down with the
boom.
To switch on the boom floating:
1.
Lower the attachment
on the ground to the
position where it will be
used
2.
Switch on the floating
with a switch on the
dashboard, see page
49.
Boom floating indicator light on the dashboard is lit
when the system is switched on.
If the loader is also equipped with
the Smooth drive option, the
floating function will be activated
whenever the smooth drive is
activated.
Some attachments have a floating
linkage built in the attachment
coupling, making use of the
floating on the loader unnecessary.
Refer to the operator’s manual of
the attachment for more
information.
