Use the following procedure.
1.
Chock the trailer tires to prevent the trailer from moving.
A
2.
Use ramps with sufficient length, width, strength and
gradient. Attach the ramps so its angle (A) to the
ground is 15 degrees or less.
3.
Remove chains or wire ropes that have been fixing
the machine.
4.
Start the engine, and move down the pilot control
shut-off lever to the "UNLOCKED" position.
5.
On the switch box, press the travel speed select
switch to set it to the LOW (1st) speed.
6.
Raise the boom slowly.
7.
Raise the attachment. With the arm retracted to
under the boom, raise the dozer (if equipped) and
travel slowly.
8.
Level the machine at the rear end of the trailer and
stop temporarily.
9.
Make sure the machine position is alighted parallel
to the ramps, and adjust the angle between the arm
and boom to 80 to 100 degrees.
When this machine is traveling up or down the ramp, fold the arm and attachment and raise the boom to avoid
interference with the ramp or trailer bed, as shown in the figure.
When the clearance between the ramp or the trailer bed is insufficient, the machine may abruptly lean to one side
when it goes over the ramp top, and strike its arm or bucket cylinder against the trailer bed, ramp, or ground,
resulting in damage to the cylinder.
10. Until the machine completely passes through the
ramps, travel down the ramps slowly with moving
the boom and the arm slowly to keep the bucket
close to the ground so that it can be lowered to the
ground in an emergency.
11. Slowly swing the upper structure 180 degrees to
take the front traveling position (so the travel
reduction unit comes to the rear).
