This section shows how to use correctly and safely the options that are installed to your loader.
Most of the options can be installed to your loader by your Avant service point. Contact your dealer or service point
for more information and availability of the options.
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.
Boom floating
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 31.
Boom floating indicator light on the dashboard
is lit when the system is switched on.
During boom floating, some air may become sucked
into the lift cylinder. To avoid unexpected or
inaccurate movements of the boom, the air in
cylinders must be removed by moving the boom to
extreme lift positions after switching off the floating
system.
After use of boom floating
WARNING
Risk of unexpected movements -
Move the loader boom after you
have switched off the boom
floating to remove air from
cylinders. During the use of boom
floating air can get trapped in the
hydraulic system. This can cause
inaccurate movements of loader
boom and the boom can even
move down.
Therefore
the
boom
and
attachment coupling plate should
always be moved to extreme end
positions after switching off boom
floating.
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.
