5. Make sure the red-colored grounded air hose
(HG) is connected and the hose ground wire is
connected to a true earth ground.

Hose
6. Use an ohmmeter (or megohmmeter in the ohm
range) to measure the resistance between the
gun handle (BB) and a true earth ground (CC).
The resistance should not exceed 100 ohms.
7. 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.

8. Use an ohmmeter (or megohmmeter in the ohm
range) to measure the resistance between the
cabinet ground lug (214) and a true earth ground
(CC). The resistance must be less than 100
ohms.
