500 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
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 23.6 in
(600 mm) and additional lifting height
is 19.1 in (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 or Smooth drive options are tted.
If the loader is also equipped with
the Smooth drive option, the oating
function will be activated whenever
the smooth drive is activated.
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, if the
loader is equipped with the Smooth
drive option.
Keep the boom oating switched
off during normal use of the loader,
when not workin or lifting with the
loader.
