Important: The spray gun must be earthed to dissipate any electrostatic charges which may be 
created by fluid or air flows.  This can be achieved through the spray gun mounting, or conductive 
air/fluid hoses.  Electrical bond from the spray gun to earth should be checked with an Ohm meter.  
A resistance of less than 10

Ohms is recommended
