5.6       Overload Circuit Breaker
The overload circuit breaker interrupts the power
supply to the machine in the event of a mechanical
overload.                                                                                               5

Re-connect the hedge trimmer to the power supply.
If the motor does not restart, the overload circuit
breaker has not cooled down properly.                                                                           1.
