Chapter 11 – Troubleshooting

TB42/TB50 – 0075251EE

Symptom

Booms drift down.

Drive functions do
not work.

Wheels will not turn when
winching.

Only slow drive speed works.

Steer wheels do not turn right or
left on machines with tow option.

Tilt alarm does not work.

Circuit breaker will not reset.

Electrical outlet does not work.

Improper AC generator output
voltage.

Possible Cause

The emergency lowering valve is
open.

Hydraulic system malfunction.

The drive/boom switch is in the boom
position.

Machine on too steep a grade.

Drive hubs are disengaged.

Low hydraulic system pressure.

Platform overload sensor is tripped.
The horn is sounding and red over-
load light is blinking.

Platform overload sensor is in error
mode. The horn is sounding and red
overload light is constantly on.

Drive hubs are engaged.

The booms are elevated. High range
not selected.

Tow kit steering float valve is open.

Booms are stowed.

Electrical circuit has not had time to
cool.

Electrical system malfunction.

Power supply not plugged in.

Machine/generator switch not in the
generator position.

Hydraulic oil is cold and thick.

Corrective Action

Turn the emergency lowering knob to
close the valve.

Stow the machine and do not oper-
ate until repairs are made.

Place the switch in the drive position.

Lower the booms and drive to a level
surface.

Turn drive wheel disconnect plates
around so nipples point outward.

Stow the machine and do not oper-
ate until repairs are made.

Remove weight from the platform un-
til the load is at or below rated ca-
pacity.

Remove weight from the platform un-
til the load is at or below rated ca-
pacity. Cycle machine power off, then
on. If alarm continues, system may
need recalibration.

Turn drive wheel disconnect plates
around so nipples point inward.

Completely lower the booms. Place
the drive range switch in the high po-
sition.

Close the steering float valve.

Normal operation. The tilt alarm is not
active until the booms are elevated.

Wait a minute or two for circuit to
cool, then push circuit breaker but-
ton in to reset.

Do not operate machine until repairs
are made.

Plug the power cord into the power-
input connector on the generator.

With engine running, place the ma-
chine/generator switch in the genera-
tor position.

Use cold weather hydraulic oil as rec-
ommended. Warm oil before operat-
ing the machine.
