Chapter 9 – Operation
40 S1930E/S1932E/S2632E – 1360460
Note
To make an emergency stop push the emergency stop
inward button 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 – S2632E Only
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
8 ′ (2.4 m). 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
6 ′ (1.8 m) the aerial platform may be driven with the
full range of drive speeds.
When the platform is elevated above 6 ′ (1.8 m) only
the slowest drive speed will work.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could 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 7 ′ 7 ″ (5.3 m) in 30 seconds,
when elevated above 6 ′ (1.8 m).
Drive/Lift Level Sensor Interlock
When the platform is elevated above 6′ (1.8 m), lift and
drive functions are interlocked through a level sensor
system. If the chassis is tilted more than two degrees
side-to-side or front-to-rear, platform 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 platform
raise and drive functions, lower the platform and drive to
a level surface.
Fold Down Guardrails
The platform guardrails may be folded down to pass the
machine under low height obstructions, if the machine
is so equipped.
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
retract the extension deck.
2. Remove the upper control panel from the side guard-
rail and place it on the floor of the platform.
3. Remove the pins (refer to Figure 9.6) that connect
the front panel to the guardrails on the right side of
the platform extension. Fasten the front panel to the
mid rail on the left side of the platform.
