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.
9. When the machine is raised up to a height of about
50 mm from the ground, adjust the machine so that
the machine is in a horizontal position while
checking the position of the yellow bubble in the
leveling instrument. At this point, if “automatic” is
selected for the mode selection switch (3), the
machine is automatically leveled so that it is in
horizontal condition.
10. When you are finished setting all outriggers, set all
outrigger switches to the “NEUTRAL” position.
11. Make sure that all of the four outrigger grounding lamps
(3) on the monitor are lit in green.
NOTES
All of the crane stowage lamp (1), the four outrigger
extension lamps (2) and four outrigger grounding lamps
(3) are lit in green.
CAUTION
If any of the outrigger grounding lamps (3) are
blinking red, remove the cover (7) of the outrigger
adapters (6) part and check them for foreign materials
being caught in the bend sections.
