Page 12: Setup
Setup Setup Close fluid valves A and B. Connect A (ISO) and B (RESIN) fluid hoses to fluid manifold. B (RESIN) Engage piston safety lock, page 10. Connect gun air whip hose (V) and air valve (W*) to main air hose. Attach fluid manifold (M) to gun. To change position of fluid manifold or use optional fluid inlets, see pages 16 and 17. - Page 13 Open cleanoff air valve (K) 1/4-1/2 turn and trigger gun to check that cleanoff air is flowing. Adjust as desired.This step does not apply with spatter spray gun 248408. Engage piston safety lock, page 10. Turn on proportioner. Open B (RESIN) fluid valve (about three half turns).

Page 14: Shutdown
Grease gun daily to prevent 2 component curing and keep fluid passages clean. Purge air carries grease mist through air chamber (AC), impinge- ment ports (IP), and out mix chamber nozzle (N), coating all surfaces. Use Graco 117773 Grease, see page 43. Purge Air Fluid... -
Page 15: Pressure Relief Procedure
Pressure Relief Procedure WARNING Read warnings, page 7. Relieve pressure before cleaning or repairing gun. Engage piston safety lock, page 10. CAUTION Air supply is required for gun actuation. Do not dis- connect gun air supply until fluid pressure is relieved. Close fluid valves A and B. -
Page 16: Optional Configurations
Optional Configurations Optional Configurations Optional Fluid Manifold Position Fluid manifold is mounted to bottom of gun, with A side on left, viewed from operator’s position at back of gun. If desired, manifold may be moved to top of gun. Doing this will reposition A side parts (fluid inlet swivel, check valve, side seal cartridge, and mix chamber) to right. -
Page 17: Optional Hose Position
Optional Hose Position Fluid inlet swivels and air quick disconnect fitting point to rear. If desired, these positions can be changed so hoses travel downward. CAUTION To prevent cross-contamination of gun’s wetted parts, do not interchange A component (isocyanate) and B component (resin) parts. -
Page 18: Flat Spray Tips
Flat Spray Tips Flat Spray Tips Follow Pressure Relief Procedure, page 15. Remove air cap (10) and flat spray tip (39). Inspect o-ring (40). If tip is stuck, pry off with small screwdriver or pull off with pliers. Tip is hardened to resist damage. To clean, soak tip in compatible solvent, see page 20. -

Clean Mix Chamber Nozzle Engage piston safety lock, page 10. Refer to T 1. Also see identification chart ABLE under Drill Bit Kits, page 39. Use the appropriate size drill bit to clean mix chamber nozzle (N). If necessary, clean air cap (C) gently with stiff brush. Table 1: Nozzle Drill Bit Sizes Round Spray Mix Chamber... - Page 22 Maintenance Push mix chamber forward until impingement ports (IP) are visible. See T 3 for appropriate size ABLE drill to clean ports. Also see identification chart under Drill Bit Kits, page 39. Some mix chambers have counterbored holes (CB) and require two drill sizes to clean impingement ports completely.

Page 23: Troubleshooting
Troubleshooting Follow Pressure Relief Procedure, page 15, before checking or repairing gun. PROBLEM Gun does not fully actuate when trig- gered. Fluid does not spray when gun is fully actuated. Gun actuates slowly. Gun delays, then actuates abruptly. Loss of round pattern. Loss of flat pattern. - Page 24 Troubleshooting PROBLEM A and/or B fluid in gun air section. Fluid mist from mix chamber or air cap. Excessive overspray. Rapid buildup of material on air cap. Reduced cleanoff air. Excessive cleanoff air when fluid valves are closed and gun is trig- gered.
