LOADING AND UNLOADING WITH TRAILER
PRECAUTIONS FOR LOADING AND UNLOADING WITH TRAILER
k k
WARNING
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 minimum, reduce the speed and
proceed slowly.
• In cold areas, perform the warming-up operation thor-
oughly and make sure that the engine speed is stable
before performing the loading or unloading the ma-
chine.
• Never correct your steering on the ramps. It is danger-
ous that the machine may tip over by the impact.
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 will change sud-
denly at the joint between the ramps and the loading
platform, and there is danger of the machine losing its
balance.
Accordingly, pass this point slowly.
• If it is necessary to swing the work equipment on the
trailer platform, the footing is unstable, so be extreme-
ly careful that the machine does not tip over.
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 the
ramps or trailer platform because the operating effort
may suddenly change.
