What to do if Stanley Power Tool shows NOK, even if it sets rivet correctly?

If your Stanley Power Tool shows 'NOK' even when it sets a rivet correctly, it might be due to an incorrect judgement range setting. Try setting the judgement range correctly or setting an appropriate range. Ensure you fasten 5 rivets in average mode; if there's an error, try again. Jaw slippage can also cause this, so perform maintenance around the jaw area. Check that the tool is at the home position, and reset it if necessary. If the issue persists, there may be a problem with the tool, so remove the cause of the issue or contact a local service center. A defective trigger module may also be the cause, requiring replacement of the motor and module assembly or contact a local service center.
