Drive Range Switch
The drive range switch (refer to Figure 4) has two posi-
tions to select drive wheel operation when the booms are
in the stowed position; tip boom fully retracted and main
boom fully lowered.
• High range (rabbit) – high speed drive 6.1 km/h (3.8
mph) with booms in the stowed position.
• Low range (turtle) – creep speed 1.2 km/h (0.75 mph)
with high torque drive operation with booms in any
position.
The drive range operates in low when the booms are out
of the stowed position, regardless of the position of the
drive range switch.
Boom Speed Knob
Use the boom speed control knob (refer to Figure 4) to
control the speed of the following boom functions:
• Main boom raise/lower
• Main boom extend/retract
• Turntable rotation clockwise/counterclockwise
Set the knob to slow (turtle) when beginning a boom
movement. The speed may be increased by slowly rotat-
ing the knob toward fast (rabbit). For smooth operation,
rotate the knob to slow when ending boom movement.
Riser Switch
The riser switch (refer to Figure 4) is used to raise or
lower the riser booms. The switch is spring returned to
the center off position.
• Hold the switch upward to raise the riser booms.
• Hold the switch downward to lower the riser booms.
Boom Extension Switch
The boom extension switch (refer to Figure 4) is used to
extend or retract the booms. The switch is spring returned
to the center off position.
• Hold the switch downward to extend the booms.

• Hold the switch downward to lower the jib.
Platform Level Switch
The platform level switch (refer to Figure 4) is used to
level the platform floor with respect to the ground. The
switch is spring returned to the center off position.
• Hold the switch up to tilt the platform floor upward or
away from the ground.
• Hold the switch downward to tilt the platform floor
downward or toward the ground.
Platform Rotation Switch
The platform rotation switch (refer to Figure 4) is used to
rotate the platform relative to the end of the tip boom. The
switch is spring returned to the center off position.
• Hold the switch to the right to rotate the platform
counterclockwise.
• Hold the switch to the left to rotate the platform clock-
wise.
Engine/Emergency Power Switch
The engine/emergency power switch (refer to Figure 4)
is used to operate turntable, boom, and platform func-
tions using the emergency power system. The switch is
spring returned to the engine position for aerial platform
engine operation.
Caution
The emergency power system is for emergency low-
ering and stowing only. The length of time the pump
can be operated depends on the capacity of the bat-
tery. Do not use this system for normal operation.
• Hold the engine/emergency power switch downward
in the direction of the white arrow to activate the
emergency power system.
• Release the switch to disengage the emergency power
system.
If the engine is running, it will stop when the switch is
placed in the emergency power position.
Horn Switch
The horn switch is to the right of the emergency stop but-
ton on the upper control panel (refer to Figure 4). Hold
the switch upward to sound the horn.
Platform Foot Switch
The upper controls are interlocked through the platform
foot switch.
Step down on and hold the platform foot switch to activate
the drive and boom functions from the upper controls.
