LOADING AND UNLOADING THE MACHINE 3
WARNING
q
During loading and unloading operations, make sure
that the low travel speed is selected (“Lo” warning
light on) and always travel at low speed.
q
During loading and unloading operations, let the
engine idle, reduce speed and operate the machine
slowly.
q
Always disable the autodeceleration function (cancel).
If this function is active, the machine may move
unexpectedly.
q
The machine must be loaded and unloaded on/from
the trailer on firm and level ground. Keep a safety
distance from the edge of the road.
q
Use sufficiently wide, long, thick and strong ramps,
and position them with a maximum inclination of 15°.
When using piled soil, compact the piled soil fully to
prevent the slope face from collapsing.
q
Before loading the machine, remove any trace of mud
and dirt from the tracks, in such a way as to prevent
the machine from slipping when it is on the ramps.
Make sure that the surface of the ramps is clean and
that there are no traces of water, snow, ice, grease or
oil.
q
Do not change direction when the machine is already
on the ramps, since it may overturn. If necessary,
move the machine down the ramps, find the correct
direction and go up again.
q
It is dangerous to use the work equipment for the
loading and unloading operations.
q
When the machine is on the ramps, do not operate any
lever apart from the travel levers.
q
The centre of gravity of the machine changes in the
point where the ramps reach the vehicle and this may
cause the machine to overturn. At this point proceed
very slowly.
q
If the turret is turned while the machine is on the truck
or on the trailer, the machine is not stable; therefore, it
is advisable to close the working equipment and
slowly rotate the turret.
q
Always make sure that the door of the cab is secured
firmly, no matter whether it is open or closed. If the
door is opened or closed on the ramps or on the
flatbed, the operating effort may change suddenly. Do
not open or close the door on the ramps or on the
flatbed.
