Figure 6.7 – Upper Control Panel Top
Start Switch
The engine can be started from the platform using the
anti-restart master switch on the front of the upper con-
trol panel (refer to Figure 6.6).
This switch is similar to an automobile ignition switch.
Turn the switch to start until the engine starts, then
release it to on. If the engine dies, the switch must be
turned to off before it can be turned back to start.
An alarm sounds when the switch is turned on to warn
others that the machine engine is being started.
Note
On some machines it may be necessary to pause about
three seconds in the on position before going to start so
the starter can engage.
Turn the switch to off to turn the engine off and save
fuel if the platform is to stay in a particular position for
a long time.
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 in to disconnect power to all con-
trol circuits at the upper controls. Pull the button out to
restore power.
Note
The lower controls override the upper controls. If the
upper control emergency stop button is engaged the
lower controls can still be used to operate the aerial
platform.
Push the emergency stop button in when the upper
controls are not in use to protect against unintentional
operation.
Boom Joystick
The boom joystick is used to raise and lower the main
boom and to rotate the turntable. The boom and turn-
table 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.
Drive Joystick
The drive joystick 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.
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. The machine
must be driving to steer the wheels. Set the steering
wheels straight ahead after completing a turn.
Drive Range Switch
The drive range switch has two positions to select drive
wheel operation:
• HI – high speed and low torque operation.
• LO – low speed and high torque operation.
Jib Articulation Joystick
The jib joystick is used to raise or lower the jib. The
joystick is spring returned to the center off position.
Note
The distance the joystick is moved is proportional to the
speed of the function.
Hold the joystick up to raise the jib. Hold the joystick
down to lower the jib.
Platform Level Switch
The level switch 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 down to tilt the
platform floor downward or toward the ground.
