Adjust the Actuator Arm

NOTE: The seat housing (4) must be in place when
removing or installing the jam nut and actuator arm.
See F 34.
IGURE
1. Install the adjustment nut (16b), actuator arm (15),
and jam nut (16a) onto the piston rod (11b).
2. Position the parts so there is a 0.125 in. (3 mm) gap
between the actuator arm (15) and the fluid packing
rod nut (E). This allows the atomizing air to actuate
before the fluid.
3. Tighten the adjustment nut (16b) against the actua-
tor arm (15). Check that the 0.125 in. (3 mm) gap
has been maintained. Tighten the jam nut (16a)
4. Test gun resistance, page.
5. Install the gun shroud (26) and air cap/tip guard
assembly (25), page 39.
6. Install the gun onto the manifold. See page 38.
