What to do if the pressure gauge drops when using an accessory with my DeWalt D55168 Air Compressor?

If the pressure reading on the regulated pressure gauge drops when an accessory is used with your DeWalt Air Compressor, it might be due to loose tube fittings. Tighten the fittings where you hear air escaping, and check them using a soapy water solution. Be careful not to overtighten the fittings.
