Dumping load

VARNING!
If visibility is limited by
the load or
attachment great care
must be taken. Walk
around the machine
before starting and make
sure no persons enter the
working area of
machine. If you
uncertain, raise the load
and check the conditions
In the operation area by
looking under the load
and operate at low speed.
If necessary, arrange for
a signalling person to
take charge and to help
the operator under
"tricky" circumstances.
Great care must be taken
to prevent injuries and
damage to property.
• If you are working on an incline, try to arrange so that the load can
be dumped uphill. This affects the stability of the machine in a
positive way.
• Keep the bucket as close to the platform or bin as possible to
achieve a smooth dumping and better control of the positioning of
the load.
• When loading rock, try to fill the first bucket with as fine material
as possible in order to soften the impact of subsequent larger
pieces.

Positioning of transporting vehicle

• The positioning of the hauler (transporting vehicle) is of great
importance for making the loading operation efficient.
• The operator should indicate where the transporting vehicle is to
stand, suitably by "pointing" with the bucket. Having done so the
operator is then responsible for that the place is safe.

Levelling

• The bucket should lie flat against the ground. To be able to fill any
hollows you should have material in and in front of the bucket when
operating forwards.
• To finish off the levelling operation, keep the edge of the bucket
slightly downward and reverse while pressing the bucket lightly
against the ground.
• The final touch can be done by reversing with the bucket flat
against the ground and with the lifting/lowering lever in floating
position. A straight bucket with a long bottom is recommended to
produce a neat job.
• If a dozer blade, snow plough or sweeper etc. is used, it may
advantageous to have the single-acting lifting function engaged.
This allows the attachment to follow any unevenness in the ground
by "floating". This also helps to maintain the steering ability and the
tractive force of the machine. The attachment always returns to the
preset position, see page 20.
Suitable bucket: Straight without teeth (alt levelling
bucket)
