The gun begins emitting air before the fluid is
discharged and the fluid stops before the air flow
stops. The packing rod assembly is pre-adjusted at
the factory for proper air lead and lag. Adjust only
if necessary, as follows.
1.
Remove the spring (17) from the nut (2k).
2.
Use a hex wrench to hold the end of the packing
rod. Turn both adjustment nuts (2j, 2k) out to
increase the lead/lag time for the air flow. The
recommended adjustment is one half turn and
not more than one full turn.
3.
Tighten the nuts together to fix them in the new
position.
