Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedurespecific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. • See Important Safety Information - MEKP, Polyester Resins and Gel-Coats and Spraying and Lamination Operations section of this manual.
Skin Injection Hazard Use with high pressure equipment, generally equipment with pressure rating of 900 psi or higher. There sions of this section. 1) manual guns, 2) UL-1450 compliant equipment 3) automatic guns,/dispense val tion valves, 4) heated hoses. Since the text contains mostly “Do not” statements, the symbols have lines them. Warnings WARNING WARNING SKIN HAZARD SKININJECTION INJECTION HAZARD - Basic High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin.
Important Safety Information Methyl Ethyl Ketone Peroxide (MEKP) MEKP is among the more hazardous materials found in commercial channels. Proper handling of the “unstable (reactive)” chemicals presents a definite challenge to the plastics industry.
Grounding Some materials may become self-igniting if applied too thickly. Read material manufacturer’s warnings and material MSDS. Moisture Sensitivity of This equipment needs to be grounded. Isocyanites Ground the(ISO) dispense through connection to a Isocyanites are gun catalysts used in two component GlasCraft approvedcoatings. groundedISO fluidwill supply hose.
Set-Up Hose Attachment 1. Push in and rotate the trigger lock to stop the trigger from being activated. 5. Attach the (Clear) trigger air tubing to the trigger air inlet fitting on the back of the gun. Isocyanate Conditions • • Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates. • 6. Attach the (black) AAC air tubing to the AAC Read material manufacturer’s warnings andair material inletto fitting on specific the side of the gun.

Pressure Relief Procedure 4. Verify the trigger lock is engaged. To relieve fluid and air pressures: 1. Push down Yellow slide valve, P/N 21402-00 to bleed off air to system. Daily Maintenance It is recommended that the following service be performed on a daily basis. 2. Open P/N 21228-00 on catalyst pump to recirculation position. 1. Remove gear cover, p/n: 23798-00, and inspect valves to see if there is any leakage, on the top or bottom side of the valves.

Maintenance 1. Ensure bores are clean before building material valves. 2. Insert bearing, p/n: 23768-01 into gun body. 3. Insert seal, p/n: 23763-00 into gun body. (Ensure holes in seal are aligned with holes in gun body.) 4. Place PTFE washers, p/n: 23721-04 on top and bottom of fluid valve, p/n: 23743-00. 5. Lubricate outside of fluid valve, p/n: 23743-00 with a generous amount of Aqua lube (21266-00) and insert into seal with holes aligned with holes in the gun body. 6.
