6. Press the GFCI RESET button. The RESET button should stay in,
flush with its base plate.
With the RESET button in and engine running, turn the circuit
breaker to the ON position. The circuit breaker should remain in the
ON position.. The circuit breaker will not remain in the ON position if
the RESET button is extended.
If the GFCI and circuit breaker do not function as described, take the
generator to an authorized Honda generator dealer for repair.
GFCI RESET BUll-ON CIRCUIT BREAKER
During generator use, if the GFCI RESET button extends and the
circuit breaker trips, this usually indicates a faulty power tool,
appliance, or cord.
If that occurs, perform test steps 1 through 6 to verify that the GFCI
and circuit breaker are in proper working order. If the GFCI and
circuit breaker test correctly, then you will know that the fault is in
the power tool, appliance, or cord. Repair or replace the faulty
power tool, appliance, or cord before further use.
