Figure 8.2 – Lower Controls
Axle Controls
To raise the boom above horizontal and to extend the
boom fully, while operating from either the lower or upper
controls, the rear axles must be extended and properly
locked into position.
The machine can be driven from the upper controls with
the axles extended or retracted. The boom must be low-
ered and retracted before beginning this procedure.
Extending The Rear Axles
1. With the machine set up for operation from the lower
controls, place the boom/axle switch (refer to Figure
8.2) in the axle position.
Danger
Make sure the area under the jack shoe is unob-
structed and can support the weight of the axles.
Use support such as an outrigger pad under the jack
shoe if necessary to increase the support area.
2. Hold the jack lever (refer to Figure 8.3) in the raise
position until the rear wheels are off the ground and
the jack has stopped lifting the chassis.

Note
It may be necessary to cycle the axle lever back and
forth, to relieve pressure on the pin, while twisting the
pin to remove it.
4. Hold the axle lever (refer to Figure 8.3) in the extend
position until the axles stop extending.
Note
Only one axle will extend at a time. They do not both
extend at the same time.
5. Fully install the pin in the lower hole in the chassis
(refer to Figure 8.5) and install the pin lock through
the pin and the lip around the hole.
Note
It may be necessary to cycle the axle lever back and
forth, to align the holes inside the chassis, while pushing
the pin into position.
