Mini-Crawler Crane M A E D A Section 4 – OUTRIGGER SETTING
1/2019 MC405C-3 4-47
WARNING!
• To lift the machine, use the four outrigger
grounding switches to evenly lift each of the
four outriggers little by little.
• When operating two outrigger grounding
switches at the same time, choose two
front switches (outrigger [1] and [4]) or two
rear switches (outrigger [2] and [3]).
Operating two left or right switches at the
same time will suddenly raise two
outriggers on one side, causing overturning
of the machine.
• Do not attempt to extend the outriggers
when they are in contact with the ground.
This will subject the outriggers to excessive
force and possibly damage them.
6. After all the trays were set, push down an
outrigger grounding switch or two of them at
the same time to the "OUT" (downward)
position.
Fig. 4-113
When the setting cylinder extends and the
machine is slightly raised, set the switch to
the "Neutral" position.
Operate the remaining switches in the same
way so that the four outriggers are raised to
the same height. Set the switch to the
"Neutral" position.
Repeat this operation to gradually raise the
machine until the rubber tracks will be at the
height of about 50 mm above the ground.

7. When the machine was raised to about 50
mm above the ground, operate the outrigger
operation switches while checking the
position of the bubble in the level to adjust
the machine to be levelled.

8. After setting the outriggers, operate all the
outrigger operation switches to the "Neutral"
position.
9. Verify that the four outrigger grounding
lamps (3) (green) on the outrigger display
are ON.
Fig. 4-116
NOTICE: On the outrigger display, all the boom
stowing lamp (1), four outrigger extension lamps
(2), and four outrigger grounding lamps (3) are
illuminated in green.
CAUTION: If any of the setting lamps (3) is
flashing in red, remove the cover (7) of the
outrigger tray (6) and check if there is any
foreign object pinched in the bending section.
