OUTRIGGER REMOVAL AND
INSTALLATION
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.
1. Shut off the engine.
2. Turn the handle counterclockwise to open the bleed
valve.
3. Wait approximately 20 to 30 seconds.
4. As necessary, separate or connect the quick
disconnects.
5. Immediately close the bleed valve.
6. Restart the engine if necessary.
Outrigger Box Removal
1. Remove the quick release pins (1) Figure 4-20 from the
ends of each of the pinning cylinder rod ends.
2. Using the crane boom for the lifting operation, fasten
lifting slings to the lifting lugs provided on each end of
the outrigger box.
3. Lift the outrigger box enough to remove the pressure off
of the ends of the pinning cylinder rod ends.
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.
