Chapter 4 – Safety Devices
This aerial work platform is manufactured with safety
devices, 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 could result from such accidents. Do not alter,
disable, or override any safety device.
If any safety devices are defective, remove the aerial
platform from service until qualified maintenance person-
nel 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-posi-
tion red push button (refer to Figure 4.1).

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.
At the upper controls, the emergency stop is a two-posi-
tion red push button (refer to Figure 4.2).
