Snorkel AB46JE - Manual (Page 15)

AB46JE – 0260072 11
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 in-
spection.
A
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 push button (refer to Figure 4.1).
Figure 4.1 – Lower Controls
Push the emergency stop button inward to disconnect
power to all control circuits.
Pull the button outward to restore power.
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 push button (refer to Figure 4.2).

Emergency Power System
The emergency power system includes a back-up pump
and motor. Use this system to operate the boom and
turntable functions to lower the platform if the main power
system fails due to low battery power or pump failure.
A
Caution
The emergency power system is for emergency low-
ering and stowing only. The length of time the pump
can be operated depends on the capacity of the bat-
teries. Do not use this system for normal operation.
Hold the emergency power switch (refer to Figures 4.1
and 4.2) in the direction of the white arrow to activate
the emergency power system.
Release the switch to disengage the emergency
power system.
The length of time the pump can be operated depends
on the capacity of the batteries.
Ground Operation Switch
The ground operation switch (refer to Figure 4.1) prevents
boom and platform movement if a control switch on the
lower control panel is accidentally moved.
Hold the switch up to operate the machine from the lower
controls.
Platform Foot Switch
Step down on the platform foot switch (refer to Figure
4.3) to activate the upper controls.
