23. Level sensor
Start the TB120 engine. Raise the platform
about three feet (1 m) then extend the main
boom as far as it will go (about six feet or 2 m)
with the rear axles retracted. Pull the level
sensor to the side as far as possible. The level
sensor alarm should sound. (The level sensor
is located inside the left-rear side of the
turntable, behind the rear cowling door.)
24. Platform-control box switches and
alarms
Check all of the platform-moving, drive, and
steering functions from the platform-control box
to see that they cause the TB120 to move the
way it should. (For correct operating
procedures see the ”OPERATION” chapter.)
Pay particular attention to the EMERGENCY
STOP switch (1) to see that it turns the TB120
engine off when struck.
Press the operator HORN (2) to see that it
works.
Listen for the motion alarm (if the TB120 has
that option) as you drive forward and backward.
Listen for the start-up alarm when the ANTI-
RESTART switch is first turned ON.
Pay particular attention to the foot switch to see
that it deactivates the platform-moving switches
when the foot switch is not stepped on.
25. GFCI (Ground Fault Circuit Interrupt)
If the TB120 has the ac generator option,
connect the power plug (inside the left-rear of
the turntable) to the ac generator then start the
TB120 engine. Set the
MACHINE/GENERATOR switch (on front of
platform-control box) to GENERATOR. If the
TB120 does not have the ac generator option,
connect a source of 125 V ac power to the
power plug inside the left-rear of the turntable.
Push the TEST button (1) in on the GFCI. The
RESET button (2) should pop out. Press the
RESET button (2) back in then set the
MACHINE/GENERATOR switch to MACHINE.
