Piston Throw Adjustment

The P2 gun piston throw is factory set and as a rule, should
not require adjustment. The piston throw refers to how far
back the air piston will travel when the gun is triggered.
Proper throw adjustment will align the mixing chamber side
ports with the side block seal thru port. There is a set screw
that determines how far the piston will travel before it stops.
To determine if the Throw is correct:
.
Turn the material ball valves, p/n PG-15-01 to the OFF
position.
