The light on the handle of my Cordless nailer is flashing red and green. What does that mean?
The nailer’s electrical system has gone into overload protection. There may be something wrong with the fan motor or the wires going to the fan motor. Remove the cap and grill to inspect the red and black fan motor wires. If the wires are pinched or broken, that may be the problem. It may also help to disconnect the small white connector on the wire assembly that goes to the motor and then reconnect it.
