Axle Controls
To raise the boom above horizontal and to extend the

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.
Extending The Rear Axles

controls, place the boom/axle switch (refer to Figure

structed and can support the weight of the axles.

shoe if necessary to increase the support area.

position until the rear wheels are off the ground and
