PRECAUTIONS TO BE TAKEN WHEN TRAVELLING ON SLOPES 3
WARNING
q
When travelling downhill on steep slopes, slow down using the travel levers and the hand accelerator.

Do not travel downhill on slopes whose inclination exceeds 15°.
q
Swinging or using the work equipment on slopes may
cause the machine to lose stability and overturn,
therefore it is advisable to avoid these operations. It is
particularly dangerous to swing the turret when the
machine is travelling downhill with full bucket. If these
operations cannot be avoided, create a sort of platform
by heaping some ground, so that the machine can
work in horizontal position.
q
Do not travel up or down steep slopes, since the
machine may overturn.
q
During travel, lift the machine at about 20-30 cm from
the ground. Do not travel downhill in reverse.
q
Do not change direction on slopes; side movements
must be carried out on level ground, or with inclination
not exceeding 10° .
q
Always operate the machine or travel in such a way as
to be able to stop it safely at any time if it slips or
becomes unstable.
q
When lifting, if the tracks slip or if it is not possible to
continue lifting using the track force only, do not use
the tractive force of the 2nd° boom to facilitate
machine movement. The machine runs the risk of
overturning.
1. When moving downhill, the driving wheel (1) must be
located downstream. If the machine is moving downhill
with the driving wheel (1) positioned upstream, the tracks
tend to loosen that can cause the slipping.
