Before operating from the upper controls, properly set
up the aerial platform as described under Preparing for
Operation. Use the following procedure to operate the
aerial platform from the upper controls.

1. From the lower controls, place the control selector

switch in the upper position.

Note
The upper controls will not operate while the control
selector is in the lower position.

2. Enter the platform and secure the chain, or optional

swinging gate.

3. Pull the emergency stop button out.

4. The aerial platform may be driven and the platform

may be raised and lowered from the upper controls.

Driving

The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a
tip-over accident. Do not drive an elevated aerial
platform on soft, uneven, or sloping surfaces. Do
not drive a fully stowed machine on grades that ex-
ceed 20 percent.

A fully stowed machine may be operated on grades up
to 20 percent. A grade of 20 percent is a 24

(61 cm) ver-

tical rise in 10

(3.05 m) horizontal length.

Death or serious injury can result from improperly
driving or steering the aerial platform. Read and un-
derstand the information in this manual and on the
placards and decals on the machine before operat-
ing the aerial platform on the job.

Use the following procedure to operate the drive func-
tions.

1. Place the drive/lift selector switch (refer to Figure

9.2) in the drive position.

2. Squeeze and hold the interlock switch against the

joystick.

To move forward, slowly push the joystick
forward.

To move backward, slowly pull the joystick
backward.

Drive Speeds

The drive speed is proportional to the joystick position.
The farther the joystick is moved, the faster the travel
speed.

Drive speed ranges are interlocked through a limit
switch that senses scissors arm position. When the plat-
form is elevated below approximately seven feet, the ae-
rial platform may be driven within the full range of drive

speeds. Above 7

(2.1 m) of elevation, only the slowest

drive speed will work.

The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.

Do not use the aerial platform if it drives faster than 0.4
mph (0.6 km/h) which is 20

( 6 m) in 30 seconds when

elevated above 7

(2.1 m) even if the joystick is in the mid

or high speed position.

Drive/Lift Level Sensor Interlock

When the platform is elevated above 7

(2.1 m), lift and

drive functions are interlocked through a level sensor
system. If the chassis is tilted more than 2 degrees
side-to-side or more than 4 degrees front-to-rear, plat-
form 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 plat-
form raise and drive functions, lower the platform and
drive to a level surface.

Platform raise and drive functions may also be disabled
by the pothole protection interlock.

Steering

The steer control switch is located on the joystick (refer to
Figure 9.2). Use the following procedure to steer the aerial
platform using the upper controls.

1. Squeeze and hold the interlock switch against the

joystick.

To turn to the left, tap lightly on the left side of the
steer switch.

To turn to the right, tap lightly on the right 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.

2. Set the steer wheels straight ahead after complet-

i n g a t u r n . T h e s t e e r i n g w h e e l s a r e n o t
self-centering.

Platform

Use care when entering and exiting the platform to
avoid slipping and/or falling. Securely close the safety
chain or optional swinging gate when the platform is oc-
cupied.
