Movement of the joystick in a given direction produces
a corresponding movement of the aerial platform. The
steering and drive functions may be operated separately
or simultaneously.
Interlock Switch
The joystick has an interlock switch in the handle (refer
to Figure 6.2).
Engage the interlock by grasping the joystick and
pulling the switch toward the handle.
Engage the interlock to activate the steering, drive,
lift or speed level functions.
Steer Switch
The steer switch (refer to Figure 6.2) 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, engage the interlock switch on
the joystick and hold down the right side of the steer
switch.
To steer to the left, engage the interlock switch on
the joystick and hold down the left side of the steer
switch.
Note
The steering wheels are not self-centering. Set the steer-
ing wheels straight ahead after completing a turn.
High Speed Drive
The high speed drive button (refer to Figure 6.2) is used
to set the drive speed to high (3.1 mph [5.0 km/h]) while
the platform is in the stowed position.
Select the high speed drive button to double the top
speed of the machine.
To drive the platform forward at high speed, press the
high speed drive button and then push the joystick
forward, the direction of the red arrow.
To drive the platform in reverse at high speed, press
the high speed drive button and then pull the joystick
backward, the direction of the yellow arrow.
Low Speed Drive
The low speed drive button (refer to Figure 6.2) is used
to set the drive speed to low (0.45 mph [0.8 km/h]).
Select the low drive speed button when working in
close quarters, climbing grades, or when unfamiliar
with the machine operation.
To drive the platform forward at low speed, press the
low speed drive button and then push the joystick
forward, the direction of the red arrow.

To drive the platform in reverse at low speed, press
the low speed drive button and then pull the joystick
backward, the direction of the yellow arrow.
Note
The drive range operates in low when the platform is
out of the stowed position, regardless of the drive speed
button selected.
Platform Raise/Lower Button
The platform raise/lower button (refer to Figure 6.2) is
used with the joystick to raise and lower the platform.
To raise the platform press the platform raise/lower
button and then push the joystick forward, the direc-
tion of the red arrow.
To lower the platform press the platform raise/lower
button and then pull the joystick backward, the direc-
tion of the yellow arrow. The lowering alarm will sound
as the platform lowers.
Note
The platform will not raise or lower while driving.
Speed Level Button
The speed level button (refer to Figure 6.2) may be used
to level the platform when the aerial platform chassis is
out of level more than four degrees side-to-side or front-
to-rear. The speed level cannot be set if the aerial platform
chassis is out of level more than 13 degrees side-to-side
and 9 degrees front-to-rear.
A
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive or position the aerial platform for
elevated use near any drop-off, hole, slope, soft or
uneven ground, or other tip-over hazard.
The aerial platform must be on a fi rm, fl at surface capable
of withstanding the load forces imposed by the aerial
platform in all operating conditions before the speed
level is used.
To operate the speed level:
1. Press the platform raise/lower button and use the
joystick to raise or lower the platform to approximately
2 ′ (600 mm).
The tilt alarm will sound if the aerial platform
chassis is out of level more than four degrees
side-to-side or front-to-rear when the platform
is raised.
2. Press and hold the speed level button and the inter-
lock switch until the platform is level.
The tilt alarm will continue to sound until the
platform is level.
