Danger
Pinch points may exist between moving components.
Death or serious injury will result from becoming
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.
• Controls to drive the aerial platform are located on
the upper control panel only.
Battery Disconnect Switch
The battery disconnect is located at the left rear of the
chassis (refer to Figure 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
connect the battery to the electrical system.
Caution
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.
• Lock the battery disconnect switch in the off position
to prevent unauthorized use of the aerial platform.
Lower Controls
The lower controls (refer to Figure 6.2) are located on the
left side of the turntable. Boom and platform functions can

located on the lower control panel:
• Start button
• Emergency stop button
• Controls selector switch
• Ground operation switch
• Rotation switch
• Riser switch
• Boom elevation switch
• Boom extension switch
• Jib articulation switch
• Platform level switch
