LOADING AND UNLOADING WITH TRAILER

PRECAUTIONS FOR LOADING AND UNLOADING WITH TRAILER
k k
Always observe the following when loading or unloading
the machine from a trailer.
• Select the firm, level ground when loading or unload-
ing the machine.
Maintain a safe distance from the road shoulder.
• Always turn the auto-deceleration switch OFF (cancel).
If the auto-deceleration switch is left ON, the machine
may suddenly start moving.
• Run the engine at idle, reduce speed and proceed
slowly.
• Perform the warming-up operation thoroughly and
make sure that the engine speed is stable before per-
forming the loading or unloading the machine.
• Never correct your steering on the ramps. There is
danger that the machine may tip over.
If necessary, drive off the ramps or back on to the trail-
er and correct the direction.
• When on the ramps, do not operate any lever except
for the travel lever.
• It is dangerous to use the work equipment for loading
and unloading operations. Always use ramps.
• The center of gravity of the machine shifts suddenly at
the joint between the ramps and the trailer, and it is
dangerous that the machine loses its balance.
Accordingly, pass this point slowly.
• If necessary, swing the work equipment on the trailer
platform, keeping in mind that the base is unstable.
Therefore pay particular attention to avoid the ma-
chine from overturning.
If the work equipment is installed to the machine, pull
the work equipment in, and operate slowly to prevent
the machine from losing its balance.
• Position a flagman to give guidance to prevent the ma-
chine from coming off the ramps and to ensure safety
in the operation.
• Always check that the sliding door of the cab is at
LOCK position, regardless of whether the door is open
or closed. Avoid opening or closing the door on a
slope, since there is a danger that the operating effort
may suddenly change.
