Chapter 6 – Controls

ADanger

Pinch points may exist between moving compo-

nents. Death or serious injury can result from being

trapped between components, buildings, structures,

or other obstacles. Make sure all personnel stand

clear while operating the aerial platform.

Controls to position the platform are located on the lower

control panel on the turntable and on the upper control

panel in the platform. Drive controls are located on the

upper control panel only.

Battery Disconnect Switch

The battery disconnect is located behind the door on the

left side of the turntable above the batteries (refer to Fig-

ure 6.1).

Figure 6.1 – Battery Disconnect Switch

The battery disconnect removes electrical power from all

electrically controlled functions when in the off position.

Place the switch in the on position to electrically con-

nect the battery to the electrical system.

ACaution

Only authorized personnel should operate the aerial

platform. Unqualified personnel may cause injury

to coworkers or property damage. Lock the battery

disconnect switch in the off position before leaving

the aerial platform unattended.

Turn the battery disconnect switch off to prevent unau-

thorized use of the aerial platform.

Lower Controls

right side of the turntable. Boom and platform functions

can be operated from the lower controls. The following

Emergency Stop Button

The emergency stop is a two-position, red push button.

Push the button in to disconnect power to all control cir-

cuits. Pull the button out to restore power.

Control Selector Switch

Use the control switch to select between off, lower con-

trol, and upper control operation. Insert the key in the

switch and turn the switch to the upper controls position

to operate the aerial platform from the upper controls and

in the lower controls position for lower controls operation.

Start Switch

The start switch works like an automobile ignition switch.

Push the start button until the engine starts, then re-

lease it to on. If the engine dies, the control switch must

be turned to off before the engine can be restarted.

An alarm sounds when the switch is turned on to warn

others that the machine engine is being started.
