OPERATION

LOADING AND UNLOADING WITH TRAILER

When loading or unloading on to a trailer, set to low
speed, and do not operate the travel speed selector
switch during the operation.
Run the engine at low idling, set to low speed, and
operate the machine slowly when loading or unload-
ing.
Select firm, level ground when loading or unloading
the machine.
Maintain a safe distance from the edge of the road.
Use ramps with ample width, length, thickness, and
strength and install them at a maximum slope of 15º.
When using piled soil, compact the piled soil fully and
take action to prevent the slope face from collapsing.
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, ice, grease, or oil.
Never correct your steering on the ramps. There is
danger that the machine may turn over.
If necessary, drive off the ramps, correct the direction,
then enter the ramps again.
Do not use use the work equipment for loading and
unloading operations. It is dangerous.
When on the ramps, do not operate any lever except
the travel lever.
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 danger of the machine losing its
balance. Travel slowly over this point.
When swinging the upper structure on the trailer, the
trailer is unstable, so pull in the work equipment and
swing slowly.
Extend the variable gauge before starting the opera-
tion.
When loading or unloading, always use ramps or a platform and carry out the operation as follows.
