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.
A 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 8.2) in the raise
position until the rear wheels are off the ground and
the jack has stopped lifting the chassis.
Figure 8.2 – Top of Chassis
3. Remove the pin lock and pin (refer to Figure 8.3)
from the upper hole in the chassis.
Figure 8.3 – Rear of 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 8.4) 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.

6. Hold the jack lever in the lower position until the rear
wheels are on the ground and the jack has stopped
retracting.
Retracting The Rear Axles
The axles can be retracted by basically reversing the
above procedure.
A
Danger
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a tip-over
accident. In the event of a system malfunction, do
not retract the axles while the booms are elevated.
The booms must be completely retracted and lowered
before retracting the rear axles.
Upper Controls
The upper controls may be used for driving the aerial
platform and positioning the booms and platform while
on the job.
Use the following procedure to operate machine func-
tions using the upper controls.
1. At the lower controls, pull the emergency stop button
outward. Insert the key in the controls selector and
turn the switch to the upper control position.
2. Enter the platform and securely close the gate.
3. Attach the fall restraint lanyard to one of the anchor
points.
