Circuit Breakers
In the event of a fault occurring, the circuit breaker will trip out,
this being indicated by the button protruding out beyond its
normal position. Should this occur, the reason for the overload
must be found and the components at fault replaced or repaired.
When the repair has been completed the circuit breaker should
be reset by pressing the button until it locks in position thus
restoring the electrical supply.
On machines with full lighting, there is an extra 30A circuit
breaker.
Audible Warnings
On machines fitted with belt driven alternators, a continuous
tone audible warning will sound when start switch is in the RUN
position, but the engine is not running. This is fitted to warn the
operator that they have left the start switch in the RUN position
which will result in battery drain.
To avoid the 5 and 6 tonne dumper being driven with the
handbrake still applied, a switch is built into the system which
gives both audible warble sound and illuminated warning under
these conditions.
Engines cooled by a 'V' belt driven blower, have a switch built
into the system which senses a 'V' belt breakage and operates a
warbler audible alarm.
On hearing audible warning, take immediate action to safely
park the vehicle and stop engine until a replacement 'V' belt is
fitted. Running the engine without a 'V' belt will DESTROY IT
