Chapter 4. Safety Devices
This aerial 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 dis
-
able, modify, or ignoreanysafety device.Safety devices
are included in the daily prestart inspection.
The potential foran accidentincreases whensafety
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
platform from service until qualified maintenance per-
sonnel can make repairs.
Emergency Stop Controls
There is an emergency stop control atthe lower and up-
per controls.
At the lower controls, the emergency stop is a
two-position push button (refer to Figure 4.1).
Push the emergency stop button into disconnect power
to all control circuits. Pull the button out to restore
power.

Note
The lower controls override the upper controls. If the
upper 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-position push button (refer to Figure 4.2).
Push the emergency stop button into disconnect power
to the upper control circuits. Pull the button out to re-

rial platform, the alarm emits a loud beeping sound to
warn personnel in the work area to stand clear.
Pothole Protector Skids
The pothole protector skids automatically lower when
the platform is elevated approximately 24″ (61 cm).
Ground clearance is reduced from 2

to

(1.9 cm) when the skids lock into position (refer to Fig-
ure 4.3).
Figure 4.3—Pothole Protector Skids
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a
tip-over accident. Do not drive or position the aerial
platform for elevated use within four feet of any
drop-off, hole, or other tip-over hazard.
This protection system limits the tilt angle if a wheel is
driven into a drop-off or hole. This greatly reduces the
likelihood of the aerial platform tipping over.
The pothole protection system is for added protection
and does not justify operating near drop-offs or holes.
