3. Try to move the rails back and forth to make sure the
platform extension deck is locked in position.
Wallboard Loading Gate
The wallboard loading gate is located at the rear of the
platform and can be used for loading work materials in
the platform.
The gate must be securely fastened closed except when
personnel are loading or unloading work materials in the
platform.
Use to following procedure to load work materials in the
platform using the wallboard loading gate:
1. Remove the retaining pin from the wallboard loading
gate.
2. Swing the gate open.
3. After loading the platform, swing the gate closed and
replace the pin.
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 0.76 m (30″)
vertical rise in 3.05 m (10′) 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 4)
in the drive position.
2. 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.
3. 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.
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 Range Switch
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 3.2 km/h (2 mph)
when the platform is raised less than 2.4 m (8′) and up
to 0.6 km/h (0.5 mph) when the platform is raised above
2.4 m (8′). Place the drive range switch in high for normal
machine operation.
Caution
The extension deck is free to move when the pin is
disengaged. Make certain the pin is engaged when
the deck is extended in the working position and
when it is stowed.
Place the drive range switch in low, with the platform fully
lowered and the extension deck securely pinned, before
driving up a ramp to load the machine for transport.
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 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 below approximately
2.1 to 2.4 m (7 to 8 feet) the aerial platform may be
driven with the full range of drive speeds.
When the platform is elevated above 2.1 to 2.4 m
(7 to 8 feet) only the slowest drive speed will work.
