TILT-ALARM HORN, SIREN, & LIGHT
There is one tilt-alarm siren, one tilt-alarm horn,
and one tilt-alarm warning light on a TB120.
The siren (1) is located under the platform-
control box.

The horn (2) is located inside the left-rear of the
turntable, under the tilt alarm sensor (3).
The tilt-alarm warning light is on the platform-
control box.
The siren will emit a two-toned sound (high-low-
high-low...) if the TB120 is tilted more than 3.5
°
(7 inch rise in 10 foot run / 18 cm rise in 3 m
run) and the booms are above horizontal or
extended more than 7 feet (2 m). The warning
light will come on and the horn will emit a
continuous sound at the same time the siren
sounds.
NOTE: The platform siren will not sound if
the TB120 is being controlled from the
ground-control box.
After the siren and/or horn begins to sound, if
the tilt continues to increase, the TB120 can tip
over. When you are in control of a TB120 and
you hear either of these two warning sounds, or
see the warning light come on, you should
immediately:
1. Stop using the DRIVE/STEER controller stick
on the platform-control box.
2. Completely retract and completely lower the
booms.
3. Use the platform-control box DRIVE/STEER
controller to move the TB120 to a level surface
or more firm ground before extending or raising
the booms again.
