OPERATION

LOADING, UNLOADING WORK

Since loading and unloading of the machine is dangerous, be extremely careful.
When loading or unloading the machine, operate it slowly with the engine speed low and the trans-
mission in the 1st gear.
Use ramps having sufficient width, length, thickness, and strength. Install them securely and set their
angle to 15º or less. If the ramps are deflected largely, reinforce them with blocks.
Performthe loading work of the machine on a level and hard place. Secure sufficient distance between
the shoulder of the road and the trailer.
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 steer the machine on the ramps, since steering on the ramps can cause rolling of the machine.
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 border between the ramps and trailer, and
the machine is unbalanced and becomes dangerous. Accordingly, pass the boarder slowly.
When loading or unloading, always use ramps or a platform and carry out the operation as follows.
LOADING
1.
Perform loading and unloading on firm, level ground only.
Maintain a safe distance from the edge of a road.
2.
Properly apply the brakes on the trailer and put blocks
under the tires to ensure that the trailer does not move.
Then fix the ramps in line with the centers of the trailer
and the machine.
Be sure that the two sides are at the same level as one
another. Make the slope of the ramps a maximum of 15º.
Set the distance between the ramps to match the center
of the tracks.
3.
Set the transmission in the 1st gear and run the engine at
low idling speed.
4.
Set the travel direction toward the ramps and drive slowly.
5.
The center of gravity of the machine shifts suddenly at the border between the ramps and trailer, and the
machine is unbalanced and becomes dangerous. Accordingly, pass the boarder slowly.
6.
Stop the machine at the specified position on the trailer.
