5.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 FIG. 13..

6.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.
