6. Select the Ground mode with the mode selector switch
(2) (Extension/Ground) on the monitor or the left control
lever.
7.
Set two outrigger switches individually or
simultaneously to the “Extension” position.
When the adapters have touched the ground, with the
grounding cylinder extended, set the switch to the
“NEUTRAL” position temporarily.
Repeat the above steps for the other two switches to
allow all four outrigger adapters to come into contact
with the ground, and set the switches to the “NEUTRAL”
position.
When operating two outrigger switches at the same time, only two on the front side
(outriggers [(1)] and [(4)]) or two on the rear side (outriggers [(2)] and [(3)]) can be
operated at the same time. Simultaneous operation of the two switches for the
outriggers on either left or right side will cause the outriggers on one side to leave the
ground abruptly. This will result in overturning of the machine.
8. After all outrigger adapters have come into contact with
the ground, set two outrigger switches individually or
simultaneously to the “Extension” position.
When a grounding cylinder extends and the machine
slightly rises off the ground, set the switch to the
“NEUTRAL” position temporarily.
Repeat the above steps for the other two switches to
allow the four outriggers to raise the machine from the
ground at a constant height, and set the switches to the
“NEUTRAL” position temporarily.
Repeat the above steps to gradually raise the machine
from the ground so that the crawler belts can be
situated about 50 mm from the ground.
