2. Safety Devices
■
Safety device information
For emergency operation controls and
procedures, see the “Emergency Operation”
chapter 9, in this manual.
The devices listed in this chapter are safety
devices. They are on an AB46J to increase safety
in the work place for both the operator and other
people near an AB46J. DO NOT by-pass, disable,
modify, or ignore any of these devices. Check
them carefully at the start of each work shift to
see that they are in working order (see “Daily
Inspection and Maintenance” chapter 7).
If any is found to be defective, immediately
remove the AB46J from service until a qualified
service technician can make repairs.
❑
Emergency Power Battery
The emergency power battery powers the
emergency operating circuits. If the platform is
aloft when regular power fails, emergency battery
power is the only way to lower the platform, there
is no manual bleed down procedure.
Thus, maintenance of the emergency power
battery is very important. The emergency power
battery should always be kept at full charge and
the battery terminals kept free of corrosion.

Emergency stop switches
At the ground control box: Press the large red
Emergency Stop button in, at any time, under
any conditions, and the entire machine stops, the
drive motors and pump turn off, the brakes
automatically set, and nothing moves. This switch
must be pulled out (on) for anything to work.
At the platform control box: Press the large red
Emergency Stop button down (off) and the
entire machine stops, the drive motors and pump
turn off, the brakes automatically set, and nothing
moves. This switch must be pulled to its up (on)
position to control the AB46J from the platform.
The ground control box will override the
platform control box. If the platform control box
Emergency Stop button is down (off) the
ground control box can still be used to start
and operate the AB46J.
