Adjust the Air
Flow Lead and Lag
NOTE: The gun
begins emitting air before the fluid
is discharge
d and the fluid stops before the air flow
stops. The pa
cking rod assembly is pre-adjusted at
the factory
for proper air lead and lag. Adjust only
if necessar
y, 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.
