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 un-
stable. 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 el-
evated.
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 plat-
form 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 but-
ton 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.
4. Pull the emergency stop outward (refer to Figure 8.6).

5. Turn the anti-restart master switch to on and pause
a few seconds while the alarm sounds to alert others
that the machine is about to start. Turn the switch to
start, then release it to on. The engine will not start if
the switch is left in the on position for 30 seconds or
longer before turning it to start. The switch must be
turned back to off before the engine will start.
6. Let the engine warm to operating temperature.

boom, or platform functions.
1. Turn the boom speed knob to slow.
