WARNING
Always observe the following when loading or unloading
the machine from a trailer.
q
Select firm, level ground when loading or unloading the
machine.
Maintain a safe distance from the edge of a road.
q
Always turn the auto-deceleration switch OFF (cancel).
If the auto-deceleration switch is left ON, the machine
may suddenly start moving.
q
Always set the travel speed switch to low speed (Lo),
run the engine at low idling, and operate the machine
slowly when loading or unloading.
q
In cold areas, carry out the warming-up operation thor-
oughly and make sure that the engine speed is stable
before carrying out the loading or unloading operation.
q
Never correct your steering on the ramps. There is dan-
ger that the machine may tip over.
If necessary, drive off the ramps or back on to the trailer
and correct the direction.
q
It is dangerous to use the work equipment for loading
and unloading operations. Always use ramps.
q
On the ramps, do not operate any lever except the
travel lever.
q
The centre of gravity of the machine will change sud-
denly at the joint between the ramps and the trailer, and
there is danger of the machine losing its balance.
Travel slowly over this point.
q
If it is necessary to swing the work equipment on the
trailer platform, the footing is unstable, so be extremely
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.
q
Position a flagman to give guidance to prevent the
machine from coming off the ramps and to ensure
safety in the operation.
Always observe the following regarding the ramps and
trailer platform.
q
Use ramps with ample width, length, thickness, and
strength and install them with a maximum slope of 15°.
When using piled soil, compact the piled soil fully to
prevent the slope face from collapsing.
q
Clean the machine tracks and ramps before starting in
order to prevent the machine from slipping on the
ramps.
There is danger of the machine slipping if there is water,
snow, grease, oil, or ice on the ramp surface.
When loading or unloading, always use ramps or a platform. Proceed as follows.
