Figure 6.5 – 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 6.4).

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 6.5).

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.

Speed Knob

Use the boom speed control knob (refer to Figure 6.5) to

control the speed of the following boom functions.

• Boom extend/retract

• Jib up/down

• Platform rotate clockwise/counterclockwise

The upper control panel has a circuit breaker for the swing

(turntable rotation), lift, drive and main control circuits.

The circuit breakers are on the front of the upper control

panel (refer to Figure 6.4).

Figure 6.4 – Upper Control Panel Front

The circuit breakers protect the electrical wiring and com-

ponents from electrical overload in case of a short circuit

or other fault.

ACaution

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.
