Safety Device Information
For emergency operation controls and procedures,
see the “Emergency Operation” chapter 9.
The devices listed in this chapter are safety
devices.
They are on the ATB 42/50 to increase safety in
the work place for both the operator and other
people near the ATB 42/50.
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, remove the ATB 42/50 from service
immediately until a qualified service technician
can make repairs.

Alarms
There are two buzzers on the ATB 42/50. One is
located on the ground control box,
the other is located on the platform control box.
The buzzers are connected in parallel, they both
emit the same pattern of sound at the same time.
The tilt alarm is also located on the platform
control box.
The different alarm sound patterns these three
devices make are shown in the table immediately
below and discussed below the table.

Start-Up Alarm
When the Master Key Switch or Anti-Restart
switch is turned ON, just prior to starting, the
buzzers emit a loud continuous tone to alert
others in the area that the ATB 42/50 is about to
start. The tone will continue until the ATB 42/50
starts or the switch is turned OFF.
