OPERATION

TRANSPORTATION

When transporting the machine, observe all related laws and regulations, and be careful to assure safety.

LOADING, UNLOADING WORK

Make sure the ramp has sufficient width, length and thickness to enable the machine to be safely loaded and unloaded.
If the ramp sags appreciably, reinforce it with blocks, etc.
When loading and unloading the machine, park the trailer on a flat firm roadbed. Keep a fairly long distance between the road
shoulder and the machine.
Remove the mud from the undercarriage to prevent the machine from slipping to the side on slopes.
Be sure the ramp surface is clean and free of grease, oil, ice and loose materials.
Never change the direction of travel when on the ramps. If it is necessary to change direction, drive off the ramps and correct
the direction, then drive on to the ramps again.
When loading or unloading, always use ramps or a platform. Proceed as follows.
LOADING
1. Load and unload on firm level ground only.
Maintain a safe distance from the edge of a road.
2. Apply the trailer brakes securely, then put blocks (1) under the
tires to prevent the trailer from moving.
Set left and right ramps (2) parallel to each other and
equally spaced to the left and right of center (3) of the trailer.
Make angle of installation (4) a maximum of 15°. If the
ramps bend a large amount under the weight of the
machine, put blocks under the ramps to prevent them from
bending.
3. Set parking brake lever to the FREE position (F).
4. Set the transmission in the 1st gear and run the engine at low
idle.
5. Set the travel direction toward the ramps and drive slowly.
6. 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
border slowly.
7. Stop the machine at the specified position on the trailer.
