2. Push the drive joystick forward to move the chas-
sis forward, the direction of the red arrow. Pull the
joystick backward to move the chassis backward,
the direction of the yellow arrow. The drive speed is
proportional to the joystick position.
3. To stop drive motion, return the joystick to neutral.
Note
To make an emergency stop push the emergency stop
inward button to apply the parking brakes.
4. The steer switch is a momentary contact, rocker
switch on top of the drive joystick. This switch controls
the two front wheels to steer the aerial platform.
To steer to the right, hold down the right side of
the steer switch.
To steer to the left, hold down the left side of the
steer switch.
Note
Holding the steer switch down too long may result in
a sharp turn. This is especially true when driving and
steering at the same time. It may be easier to turn the
wheels in small increments using a series of quick taps
on the steer switch.
5. Set the steer wheels straight ahead after completing
a turn. The steering wheels are not self-centering.
Drive Speeds
The drive speed is proportional to the joystick position.
The farther the joystick is moved, the faster the travel
speed.
Always slow down and switch the drive system to low
range before traveling over rough terrain or any sloped
surface.
Drive speed ranges are interlocked through limit switches
that sense the platform position.
When the platform is elevated, only the slowest
drive speed will work regardless of the drive speed
selected.
To avoid a sudden speed change from high to low,
always bring the machine to a stop before raising the
platform from the stowed position.
A
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. Do not alter,
disable, or override any safety device.
Do not use the aerial platform if it drives faster than
0.50 mph (0.8 km/h) when the platform is out of the
stowed position.

Drive/Lift Level Sensor Interlock
When the platform is elevated above 6′ (1.8 m), lift and
drive functions are interlocked through a level sensor
system. If the chassis is tilted more than two degrees
side-to-side or front-to-rear, platform raise and drive
functions are disabled and an alarm sounds when those
controls are activated.
If the drive/lift level sensor interlock shuts off the platform
raise and drive functions, lower the platform and drive to
a level surface.
All Motion Alarm
The all motion alarm sounds loud intermittent beeps
anytime the machine functions are being operated.
Fold Down Guardrails
The platform guardrails may be folded down to pass the
machine under low height obstructions.
A
Danger
The potential for an accident increases when the fold
down rails are lowered. Death or serious injury can
result in such accidents. Do not elevate the platform
with the fold down rails lowered. Use extreme care
when moving the aerial platform while the fold down
rails are lowered.
Use the following procedure to fold down the guardrails:
1. Fully retract the platform extension deck and lower
the platform.
2. From the lower controls, turn the start switch to the
off position.
3. Enter the platform and close the gate.
4. Remove the upper control panel from the side guard-
rail and place it on the fl oor of the platform.
5. Remove the retaining pin on the wallboard loading
gate (refer to Figure 9.5) and the front guardrail (refer
to Figure 9.6).
