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, grasp the platform
extension handles, raise them and pull the extension
deck backward to retract the deck. Fully lower the han-
dles at the stowed position and ensure they are locked
in the lowered 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.

Fold Down Guardrails

The platform may have fold down guardrails to pass the
machine under low height obstructions.
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 lower the platform guard-
rails.
1. Remove all materials from the platform floor and
slightly extend the extension deck.
2. Remove the pin from the hinged top rail on the exten-
sion deck. Fold the hinged rail in as far as it will go.
3. Lift the left hand extension deck rail up and fold it
down inwards.
4. Remove the pin from the hinged top rail on the main
deck. Fold the hinged rail in as far as it will go.
5. Lift the left hand main deck rail up and fold it inwards.
6. Lift the right hand extension deck rail up and fold it
down inwards.
7. Lift the right hand main deck rail up and fold it inwards.
8. Reverse this procedure to reposition the rails.

Driving and Steering

Danger
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury will result from a tip-over
accident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive on
grades that exceed 25 percent.
S3215L/S3215E/S3219E/S3220E/S3226E/S4726E/S4732E – 1500834
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
y
the steer switch.
To steer to the left, hold down the left side of the
y
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

The drive range switch has two positions to select drive
wheel operation:
High (Rabbit) – for normal driving conditions.
y
Low (Turtle) – for driving on grades up to 25 percent
y
that require low speed and high torque operation,
where high range is not sufficient to climb the grade.
