Using an ohmmeter (AA), measure the resistance
between the gun handle (BB) and a true earth
ground (CC). The resistance should not exceed 100
ohms. See F

If the resistance is greater than 100 ohms, check the
tightness of the ground connections and be sure the
air hose ground wire is connected to a true earth
ground. If the resistance is still too high, replace the
air hose.
