spray pattern. Loosen (G) air cap and rotate horns to
achieve desired pattern. Tighten air cap.
2. Attach ma te ri al cup to the gun. NOTE: The (F) material filter
supplied is optional to protect against contaminants and
small particles. See parts list for material filter orientation.
3. Attach air supply line to 1/4 NPS air inlet.
NEVER point spray gun at self or any
oth er per son. Ac ci den tal discharge of
material may re sult in se ri ous injury.
4. Adjust air pres sure at air com pres sor.
DO NOT exceed 100 psi.
5. Depress spray gun trigger fully to spray ma te ri al. NOTE: Depressing trig ger partially will
cause only air to be re leased.
Adjust spray gun:
a. Amount of ma te ri al re leased (den si ty of “fan spray”) is con trolled by (D) fluid con trol knob.
Turn knob coun ter clock wise to in crease, or clock wise to de crease, the flu id flow.
b. Width of “fan spray” is gov erned by (B) pattern adjustment knob. Turn knob coun ter clock-
