u
Tilt Alarm
The tilt alarm warns the ATB 42/50 operator that
the ATB 42/50 is over 5° out of level. If the tilt
continues to increase, the ATB 42/50 will
eventually tip over.
A
DANGER
To prevent Death or Serious Injury, when you
hear the loud two toned (high-low-high-low...)
alarm, immediately retract and lower the
platform. When the platform is completely
down, determine and correct the cause of the
tilt before raising the platform again.
u
All Motion Alarm
The optional all motion alarm emits a loud
beeping sound anytime a platform moving switch
is used or anytime the DRIVE/STEER controller
is used. The alarm alerts people near the ATB
42/50 that some part of the ATB 42/50 is moving.
u
Descending Boom Alarm
The optional descending boom alarm emits a
loud beeping sound anytime the jib boom, main
boom, or riser booms come DOWN. The alarm
also sounds when the tip boom of the ATB 50
RETRACTS. The alarm alerts people near the
ATB 42/50 that a boom is lowering.
u
Drive Motion Alarm
The optional drive motion alarm emits a loud
beeping sound anytime the Drive/Steer controller
is in FORWARD or REVERSE. This alarm alerts
people on the ground that the ATB 42/50 is
traveling along the ground.

Other Safety Devices
u
Battery
The battery in the ATB 42/50 is a safety device
because it powers the emergency operating
circuits. If the platform is aloft and the engine
dies, battery power is the only way to lower the
platform, there is no manual bleed down
procedure. Thus, battery maintenance is very
important. The battery should always be kept at
full charge and the battery terminals kept free of
corrosion.
If an optional extra battery is installed, at rear of
turntable, it too is a safety device. The extra
battery is not connected to the standard battery.
The batteries alternate use: only one battery is
connected to the ATB electrical system at a time.
Each time the starter motor is activated the
battery used changes.
