2. SAFETY DEVICES
2 - 1 P/N 0082168
For emergency-operation controls and
procedures, see the “EMERGENCY
OPERATION” chapter in this manual.
The devices listed in this chapter are safety
devices. They are on a TB 60 to increase safety
in the work place for both the operator and other
people near a TB 60. 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 & MAINTENANCE” chapter). If
any is found to be defective, remove the TB 60
from service immediately until a qualified service
technician can make repairs.

TILT ALARM & LEVEL SENSOR
There are two tilt alarm sirens on a TB 60.
One (1) is located under the platform-control box.
2
3
One (2) is located in the turntable next to the
level sensor (3).
The sirens will both, simultaneously, emit a two-
toned sound (high-low-high-low...) if the TB 60 is
tilted more than 5
°
and the booms are not
completely retracted and completely down. After
the sirens begin to sound, if the tilt continues to
increase, the TB 60 can turn over.
When you are in control of a TB 60 and you hear
its two-toned siren, you should immediately:
1. Stop using the DRIVE controller stick on
the platform-control box.
2. Completely retract and completely lower the
booms.
3. Use the platform-control box DRIVE
controller to move the TB 60 to a level surface
or more firm ground before extending or
raising the booms again.

EMERGENCY STOP SWITCHES
At the ground-control panel: Press the red
EMERGENCY STOP cover down, at any time,
under any conditions, and the entire machine
stops, the engine turns off, the brakes set, and
nothing moves. This switch must be up for
anything on the TB 60 to work.
The ground-control panel EMERGENCY STOP
switch (1) can also be used with the door (2)
closed.
