3.4.2 Loading, unloading work with trailers
WARNING
!
When loading or unloading the machine, run the engine at
low speed, travel at low speed, and operate slowly.
!
When loading or unloading the machine, stop the trailer on
firm level ground.
In addition, keep well away from the road shoulder.
!
Use ramps of ample width, length, thickness, and strength,
and install them securely at an angle of less than 15°.
When using an embankment, compact the fill soil thoroughly
and make sure that the slope face does not collapse.
!
Remove the mud stuck to the undercarriage to prevent the
machine from slipping to the side on the ramps.
In addition, remove any water, snow, ice, grease, or oil from
the ramps.
!
Never change direction on the ramps. There is danger that
the machine may tip over.
If it is necessary to change direction, return to the ground
surface or the trailer platform, correct the direction, and start
again.
!
The position of the center of gravity of the machine will
change suddenly at the connection of the ramp and trailer,
and there is danger of the machine losing its balance.
Always drive slowly over this point.
When loading or unloading, always use ramps or a platform and
carry out the operation as follows.
