Chapter 4 – Safety Devices
This aerial work platform is manufactured with safety de-
vices, placards, and decals to reduce the likelihood of an
accident. For the safety of all personnel, do not disable,
modify, or ignore any safety device. Safety devices are
included in the daily prestart inspection.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
If any safety devices are defective, remove the aerial plat-
form from service until qualified maintenance personnel
can make repairs.
Emergency Stop Controls
There is an emergency stop control at the lower and
upper controls.
At the lower controls, the emergency stop is a two-position
push button (refer to Figure 4.1). Push the emergency
stop button in to disconnect power to all control circuits.
Pull the button out to restore power.

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.

tion push button (refer to Figure 4.2).
