Warnings 313872B 9 Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama- tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings.
Warnings 10 313872B FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help pre- vent fire and explosion: • Use equipment only in well ventilated area.
Important Two-Component Material Information 313872B 11 Important Two-Component Material Information Isocyanate Conditions Material Self-ignition Keep Components A and B Separate Moisture Sensitivity of Isocyanates Isocyanates (ISO) are catalysts used in two component foam and polyurea coatings.
Important Two-Component Material Information 12 313872B Changing Materials • When changing materials, flush the equipment mul- tiple times to ensure it is thoroughly clean. • Always clean the fluid inlet strainers after flushing. • Check with your material manufacturer for chemical compatibility.
Throat Seal Liquid 313872B 13 Throat Seal Liquid Grounding Check your local electrical code and proportioner man- ual for detailed grounding instructions. Ground the pour gun through connection to a Graco-approved grounded fluid supply hose. Always ground the gun when flushing.
Loss of Air Pressure 14 313872B Loss of Air Pressure Purge rod actuation is controlled by air pressure. In event of loss of air pressure, the purge rod will remain retracted, the impingement ports will remain open, and the gun will continue to pour.

Theory of Operation 18 313872B Theory of Operation Gun Triggered (Fluid Pouring) Purge rod retracts, opening the impingement ports and allowing fluid to mix and flow through the nozzle. Throat Seal Liquid lubricates the purge rod. Gun Detriggered Purge rod extends, closing the impingement ports and stopping fluid flow.
Setup 313872B 19 Setup Perform this setup procedure to get the pour gun ready for operation. 1. Close fluid valves A and B. 2. Connect A and B fluid hoses to fluid manifold. 3. Engage piston safety lock. See page 13. 4. Connect gun air whip hose (AA) and air valve (AB) to main air hose.
Setup 20 313872B 11. Engage piston safety lock. See page 13. 12. Perform Bleed Throat Seal Liquid Cartridge pro- cedure. See page 24. 13. Turn on proportioner. See proportioner manual. 14. Open fluid valves A and B. 15. Disengage piston safety lock. See page 13.
Setup 313872B 21 Optional Hose Position As shipped, fluid inlet swivel fittings point to rear of the gun. If desired, use the following procedure to make the fluid inlet swivel fittings point downward. 1. Follow Pressure Relief Procedure , page 22. 2.
Pressure Relief Procedure 22 313872B Pressure Relief Procedure 1. Engage piston safety lock. See page 13. NOTE: Air supply is required for purge rod actuation. Do not disconnect gun air supply until fluid pressure is relieved. 2. Close fluid valves A and B.
Shutdown 313872B 23 Shutdown Short Term Shutdown Perform Short Term Shutdown procedure if gun will not be used for more than one hour. 1. Perform Pressure Relief Procedure on page 22. 2. Trigger gun 3-4 times with piston safety lock engaged in order to ensure material does not build up on the purge rod.
