3. Try to move the rails back and forth to make sure the
platform extension deck is locked in position.
Use the following procedure to retract the platform:
1. Enter the platform and secure the doors.
Caution
The extension deck is free to move when the exten-
sion handle locks are disengaged. Personal injury may
result from accidentally extending or retracting the
deck. Make certain both extension handle locks are
fully engaged when the deck is extended in the work-
ing position and when it is stowed. Do not attempt to
extend or retract the platform unless the aerial platform
is on a level surface.
2. While facing the front of the platform, firmly grasp each
of the latch handles and squeeze firmly to unlock the
extension deck. Pull backward to retract the extension
deck to the stowed position. Release the handles to
lock the platform in position (refer to Figure 9.3).
3. Try to move the rails back and forth to make sure the
platform extension deck is locked in position.
Driving and Steering
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 an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive on
grades that exceed 25 percent.
A fully stowed machine may be operated on grades up
to 25 percent. A grade of 25 percent is a 30″ (0.76 m)
vertical rise in 10′ (3.05 m) horizontal length.
Warning
Death or serious injury could 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 operating
the aerial platform on the job.
Use the following procedure to operate the drive and
steer functions.
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.
3. Push the drive joystick forward to move the chassis
forward. Pull the joystick backward to move the chas-
sis 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
button inward to apply the parking brakes.
5. 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.
6. Set the steer wheels straight ahead after completing
a turn. The steering wheels are not self-centering.
Drive Range Switch – S4732E
The drive range switch has two positions to select drive
wheel operation:
High (Rabbit) – for normal driving conditions.
Low (Turtle) – for driving on grades up to 25 percent
that require low speed and high torque operation,
where high range is not sufficient to climb the grade.
In high the machine will travel up to 2 mph (3.2 km/h)
when the platform is raised less than 8′ (2.4 m) and up
to 0.5 mph (0.8 km/h) when the platform is raised above
