CIRCUIT BREAKERS
The circuit breakers are resetable electrical circuit
protection devices. They stop the flow of current
in the event of a circuit overload. Once a circuit
breaker is tripped, reset it manually by pressing
the reset button after the breaker has cooled
down.
If the overload that caused the circuit breaker to
trip is still there, the circuit breaker will continue to
stop current flow until the problem is corrected.
The fuse is a one-time circuit protection device
designed to stop the flow of current in the event of
a circuit overload. Never substitute higher value
fuses than those specified in this manual.
The circuit breakers are located to the left of the
operator’s compartment near the machine and
battery connectors and on the control boxes. The
fuses are located in the main control box.
The chart shows the circuit breakers and fuses,
and the electrical components they protect.
