the off position. Place the switch in the on
position to operate any electrically controlled
function.

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.

Emergency Stop Switch

The emergency stop is a two-position toggle
switch with a red safety guard. Push the red
safety guard down over the toggle switch to
disconnect power to all control circuits. Lift the
guard and push the toggle switch up to restore
