LOADING AND UNLOADING WITH TRAILER 3
WARNING
q Always turn the auto-deceleration switch OFF (cancel)
during loading and unloading operations.
If the auto-deceleration switch is left ON, the machine
may suddenly start moving.
q When loading or unloading the machine on a trailer,
always travel at low speed. Do not operate the travel
speed selector switch.
q Run the engine at low idling, set to low speed, and
operate the machine slowly when loading or unload-
ing.
q Do not carry out loading or unloading operations dur-
ing the automatic warming-up operation.
If the automatic warming-up operation is canceled
before completion, the travel speed may suddenly
change.
q Select firm, level ground when loading or unloading
the machine.
Maintain a safe distance from the edge of the road.
q Use ramps with ample width, length, thickness, and
strength and install them at a maximum slope of 15°.
When using piled soil, compact the piled soil fully and
prevent the slope face from collapsing.
q Remove all mud and dirt from the machine tracks
before starting in order to prevent the machine from
slipping on the ramps.
Be sure that the ramp surface is clean and free of
water, snow, grease, oil, or ice.
q Never correct your steering on the ramps. There is a
hazard that the machine may turn over.
If necessary, drive off the ramps, correct the direction,
then enter the ramps again.
q It is dangerous to use the work equipment for loading
and unloading operations.
q When on the ramps, do not operate any lever except
the travel lever.
q The center of gravity of the machine will change sud-
denly at the joint between the ramps and the track or
trailer, and there is a hazard of the machine losing its
balance. Travel slowly over this point.
q When swinging the upper structure on the trailer, the
trailer is unstable, so pull in the work equipment and
swing slowly.
When loading or unloading, always use ramps or a platform and carry out the operation as follows.
