Adjust the Actuator Arm
1. Install the adjustment nut (30), actuator arm (29),
and jam nut (28) onto the piston rod (34b). Note that
the jam nut (28) has a slightly larger hex and a thin-
ner profile than the adjustment nut (30). See F
IG .
30. on page 42.
2. Position the parts so there is a 0.125 in. (3 mm) gap
between the actuator arm (29) and the fluid packing
rod nut (U), which allows the atomizing air to actuate
before the fluid. See F
IG . 32..
3. Tighten the adjustment nut (30) against the actuator
arm (29). Check that the 0.125 in. (3 mm) gap has
been maintained. See F
IG . 32..
4. Test gun resistance, page 29.
5. Install the gun shroud (2) and air cap, page 37.
