Overload Circuit Breaker

(E 160, E 180 C)
The overload circuit breaker
interrupts the power supply to
protect the motor in the event of
mechanical overload (e.g. cutting
for extended period with excessive
feed force, suddenly stopping the
chain by pinching it in the cut).
Warning: The overload circuit
breaker and chain brake switch
must never be bypassed.
