I've looked and looked to see if I can find any information on this.
I'm wondering if anyone can tell me how air flows through the manifold/solenoid from the regulator, then back through the manifold to the bolt so that the marker can fire.
The three holes shown on the front face here (I know the larger 2 are screw holes)
I figure one is IN, one is OUT, one is possibly exhaust?
Also, is the #010 o-ring the both the input from the reg (assuming) and output the front portion of the bolt, while the #007 o-ring the input to the rear of the bolt that controls when the marker fires?
Thanks for any information you can give me.
