The circuit breakers protect the electrical wiring and com-
ponents from electrical overload in case of a short circuit
or other fault.
A
Caution
A tripped circuit breaker indicates a malfunction in
the electrical system. Component damage can re-
sult if the cause of the malfunction is not corrected.
Do not operate the aerial platform if the circuit
breaker trips repeatedly.
Push the button to reset the circuit breaker.

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 re-
lease 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 6.6).
Push the button in to disconnect power to all control cir-
cuits at the upper controls. Pull the button out 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 in when the upper con-
trols are not in use to protect against unintentional op-
eration.
Drive/Boom Selector Switch
Place the drive/boom selector switch (refer to Figure 6.7)
in the drive position to drive the aerial platform.
Place the drive/boom selector switch in the boom posi-
tion to operate the boom functions.
Note
Boom and drive functions can not be operated at the
same time.
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 coun-
terclockwise and to the left to rotate the turntable clock-
wise.
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 oper-
ated simultaneously.
