Use the following procedure to operate the drive and
steer functions.
1. Place the lift/drive handle (refer to Figure 8.6) in the
drive position.
2. Step down on the platform foot valve.
3. Push the drive joystick forward to move the chassis
forward. Pull the joystick backward to move the
chassis backward. The drive speed is proportional
to the joystick position.
4. 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.
5. The steer handle controls the two front wheels to
steer the aerial platform.
y
To steer to the right, hold the handle in the steer
right position.
y
To steer to the left, hold the handle in the steer
left position.
Note
The steering wheels are not self-centering. Set the steer-
ing wheels straight ahead after completing a turn.
6. After driving to the desired location, release the foot
valve, or push the emergency stop button inward to
apply the parking brakes.
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.
y
When the platform is elevated, only the slowest
drive speed will work regardless of the drive speed
selected.
y
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
0.64 mph (1 km/h) when the platform is out of the stowed
position.
Fold Down Guardrails
The platform guardrails may be folded down to pass the
machine under low height obstructions.
A ½″ wrench and socket will be needed to remove the
hardware from the guardrail.
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 guard-
rails:
1. From the lower controls, fully lower the platform and
turn the machine off.
2. Enter the platform and close the gate.
3. Remove the upper control panel from the side guard-
rail and place it on the floor of the platform.
A
Caution
The rails are free to move downward after removing
the hardware. Improper lifting can cause personal
injury. Be prepared to hold the weight of the rails
before beginning to lower them onto the platform.
4. At the front of the platform, remove the snapper pins
from the corners of the front guardrail. Refer to Figure
8.8.
Figure 8.8 – Platform
5. Fold the front guardrail inward so it rests on the plat-
form.
