2.24 OUTRIGGER STOWING OPERATION
• Do not let people approach toward the machine when stowing the outriggers.
Staying around the machine may result in serious accidents such as getting caught between
an outrigger and the main unit of the machine.
• Verify that there is nothing under the rubber tracks when stowing the outriggers.
If there is any object under the rubber tracks, the machine may overturn and serious accidents
may occur when stowing the outriggers.
• Stop the engine for operation except for extending/setting the outrigger cylinders.
The third person touching an outrigger may result in sudden movement of the outrigger
cylinder, which may lead to serious accidents.
• When the position pin is removed, the outrigger loses the support and rotates. Always hold the
outrigger with one hand when removing the position pin.
• Do not put your hands or fingers around the gaps of movable areas when stowing the
outriggers. Your hands or fingers may get caught, and it may lead to serious accidents.
• Insert the position pin to the end when stowing the outriggers.
• There are four outriggers. Be careful not to mistake 8 outrigger switches for the others. Check
the numbers shown on the “operation plate” at the switch section and the location of the
“number plate” affixed to the outriggers. Wrong operation can lead to serious accidents.
• When operating two outrigger setting 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.
• Reduce the engine speed to low speed when operating the outrigger switches.
At the high engine speed, the outriggers operate suddenly, leading to serious accidents such
as overturning of the machine.
• When lowering the raised machine, operate the eight outrigger switches so that the four
outriggers are lowered little by little. Suddenly retracting two outriggers just on the right side
or left side will cause instability in the machine and it can overturn the machine.
• Do not perform the outrigger extending operation after they are set on the ground. Doing so
applies unreasonable force on the outriggers, resulting in the outrigger breakage.
• Always set the traveling lock lever to the “LOCK” position when operating the outriggers.
CAUTION
• Always keep the boom at the “lowest position and slew and stow position” when operating the
outriggers. The outriggers cannot be operated if the boom is not stowed completely. (Verify
that the boom stowing lamp (green) on the outrigger display is ON.)
• Operate the work selector switch on the outrigger operation panel to the “OUTRIGGER”
position.
[1] TASKS TO BE PERFORMED AFTER STARTING ENGINE
Although the stowing method is described for just one outrigger
(outrigger (4)), stow the other three outriggers in the same way.
1. Operate the traveling lock lever (8) to the “LOCK” position.
