TRANSPORTATION PROCEDURE

When transporting the machine, choose the transportation method in reference to the weight and dimensions of
machine.
Note that the "SPECIFICATIONS" (weight and dimensions) vary depending on the type of tire and bucket.

LOADING AND UNLOADING WITH TRAILER

• When loading or unloading the machine, run the engine at a low speed and operate the machine
slowly in low travel speed.
• Select a flat and firm ground when loading or unloading the machine.
Maintain a safe distance from the road shoulder
• 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.
• Remove mud from the undercarriage of the machine so that the machine will not slip sideways on
the ramps.
In addition, remove water, snow, ice, grease, oil, etc. from the ramps.
• Never correct your steering on the ramps. There is danger that the machine may tip over.
If it is necessary to change the travel direction, return to the ground or to the bed of the trailer, then
change the travel direction.
• The center of gravity of the machine shifts suddenly at the joint of the ramps and the trailer, so
there is a danger of the machine losing its balance. Accordingly, pass this point slowly.
When loading or unloading, always use ramps or a platform. Proceed as follows.
PROCEDURES FOR LOADING MACHINE

If the ramps bend a large amount under the weight of the
machine, put blocks (5) under the ramps to prevent them
from bending.
