AVANT 423 - Loader Boom Operation and Floating

30
400 SeriesOperating instructions
Loader control
The loader boom and bucket are controlled with the multi-
function lever sideways (tilt) and back & forward (boom up
& down).
• Pull backward to lift the boom
• Push forward to lower the boom
• Push left to raise the tip of the
bucket (lling)
• Push right to lower the tip of
the bucket (emptying)
For details about how to operate the loader with different
attachments, refer to the Operator’s manual of each
attachment. For example, instructions regarding the use
of a bucket are shown in the operator’s manual of bucket.
Telescopic boom (option)
The telescopic boom makes many
tasks easier, also those that do
not involve lifting. You can, for
example, push material further with
a bucket, reach into difcult areas,
and improve visibility to the work
area with some attachments.
Telescopic boom is operated with
the control lever on the control
panel (see page 25). Turn the
control lever of the telescopic boom
to the right to extend the boom, and
turn to the left to retract it.
Length of the telescope is 600 mm
and additional lifting height is 485 mm.
Risk of tipping over - Extended
boom can cause the loader to
tip over. Use telescopic boom with
caution. The stability of the loader
depends on the distance of the load
from the front of the loader. When you
extend the boom, you increase the
effect of the weight and reduce safe
handling capacity. See pages 22 and
50 for further instructions about tipping
load and safe material handling.
Boom floating (option)
The oating system releases the lift cylinder to allow it to
move upwards. This will allow the attachment to follow the
contours of the terrain, making grading and leveling work
easier. The boom can move upwards from the position
where the boom oating is switched on.
1. Lower the boom down. With some attachments and work
tasks, it may be useful to press down the attachment
before you switch on the oating.
2. Switch on the oating with the
switch on the dashboard, see
page 24
3. Boom oating indicator on the
dashboard lights up
NOTE: The switch is installed on the dashboard, also
in cases the boom oating option is not installed on the
loader. The presence of the switch does not mean the
boom oating is tted.
The oating releases the boom to
move up from the position from where
it is switched on. Lower the attachment
rmly on the ground before you switch
on the oating. In some tasks, it may
be useful to press the attachment
down so, that the front wheels of the
loader lift off from the ground.
Some attachment have a oating
linkage built in the attachment coupling,
making use of the oating on the loader
unnecessary. Refer to the operator’s
manual of the attachment for more
information.
Risk of lowering of the boom when
switching on boom oating - Lower
boom to close to the ground before
switching on boom oating. Switch
on the boom oating only when
stationary and when the load is close
to the ground. Boom can move down
when you switch on the boom oating.
Keep the boom oating switched
off during normal use of the loader,
especially when lifting loads with the
loader.
