12 A62JRT – 104850-000
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 upward to retract the booms.
Jib Articulation Switch
The jib articulation switch (refer to Figure 4) is used to
raise or lower the jib. The switch is spring returned to the
center off position.
• Hold the switch upward to raise the jib.
• 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 functions
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
lowering and stowing only. The length of time the
pump can be operated depends on the capacity of the
battery. 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.
Snorkel Guard Override Switch
When the Snorkel Guard system is activated, the Snor-
kel Guard override switch (refer to Figure 4) is used to
override the system to operate main boom down, riser
boom down, or jib down functions. The switch is spring
returned to the normal operation position.
• Hold the switch upward to override the Snorkel Guard
system.
•
Release the switch to the downward position to re¬sume
normal machine operation.
