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 FIG.

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 FIG. 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 FIG. 32..

4. Test gun resistance, page 29.

5. Install the gun shroud (2) and air cap, page 37.

6. Install the gun onto the manifold and bracket. See

page 36.
