OUTRIGGER REMOVAL AND
INSTALLATION
DANGER!
Tipping Hazard
When lifting the outrigger box on rubber the machine may
tip over. The boom must be fully retracted and limited to a
6 m (20 ft) maximum radius.
With one outrigger box installed the machine may become
unstable. Do not swing over the end with the outrigger box
already installed while installing the other outrigger box.
The boom angle must not be less than 35° when over
sides of the machine; loss of stability will occur causing a
tipping condition. To lower boom below 35° boom angle,
boom must be swung over front or rear and RCL bypass
activated.

Bleed Valve Operation

The manual pressure bleed-off valve (1) (Figure 4-19) is
located on the back of the right rear fender. The purpose of
the valve is to reduce the effort required to separate and
connect the hydraulic quick disconnect couplers when
removing or installing the front and rear outrigger boxes.
