Hold the joystick to the right to steer the aerial platform
to the right and to the left to steer to the left as indicated
by the directional arrows on the chassis.
Note
The steering wheels are not self-centering. Set the steer-
ing wheels straight ahead after completing a turn.
Drive Range Switch
The drive range switch (refer to Figure 6.7) 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.
• HI – high speed drive (3 mph) with booms in the
stowed position.
• LO – creep speed (0.6 mph) with high torque four
wheel 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.
Jib Articulation Switch
The jib articulation switch (refer to Figure 6.7) 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 6.7) 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 6.7) 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.
If the platform is to stay in a particular position for a long
time, turn the start switch to off to shut off the engine and
save fuel.
Emergency Stop Button
The emergency stop is a two-position, red push button on
the top of the upper control panel (refer to Figure 6.7).
• Push the button inward to disconnect power from all
control circuits at the upper controls.
• Pull the button outward to restore power.
Note
The lower controls override the upper controls. If the up-
per control emergency stop button is engaged the lower
controls can still be used to operate the aerial platform.
• Push the emergency stop button inward when the
upper controls are not in use to protect against un-
intentional operation.
Boom Joystick
The boom joystick (refer to Figure 6.7) is used to raise
and lower the main boom and to rotate the turntable.
The boom and turntable functions may be operated
simultaneously.
Note
The distance the joystick is moved is proportional to the
speed of the function.
Hold the joystick forward to raise the main boom and
backward to lower the boom.
Hold the joystick to the right to rotate the turntable
counterclockwise and to the left to rotate the turntable
clockwise.
Boom Extension Switch
The boom extension switch (refer to Figure 6.7) 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.
Drive Joystick
The drive joystick (refer to Figure 6.7) is used to control
forward and reverse motion of the aerial platform. It is
also used to steer the machine. The steering and drive
functions may be operated simultaneously.
Note
The distance the joystick is moved is proportional to the
speed of the function.
Hold the joystick forward to move the aerial platform
forward and backward to move in reverse as indicated
by the directional arrows on the chassis.
