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.
Some materials may become self-igniting if applied Grounding too thickly. Read material manufacturer’s warnings and material MSDS. Moisture Sensitivity of Isocyanites This equipment needs to be grounded. Isocyanites (ISO) are catalysts used in two component Ground dispense gun through to a moisture foam andthe polyurea coatings. ISOconnection will react with GlasCraft approved grounded fluid supply hose. (such as humidity) to form small, hard, abrasive crystals, which become suspended in the fluid.
Set-Up Hose Attachment 4. Attach the (stainless steel p/n 20190-00) catalyst hose to the catalyst inlet fitting on the back of the gun. 1. Engage the trigger lock. 5. If the optional fiberglass roving chopper is being used, attach the “red” chopper air line to the chopper air inlet fitting on the back of the gun. Rotate trigger lock to stop the trigger from being activated. 2. Attach the (black p/n 21694-25) material hose to the material inlet fitting on the back of the gun. 3.

Pressure Relief Procedure 4. Verify the Trigger Lock is in the Locked position. To relieve fluid and air pressures: 1. Push down Yellow slide valve, P/N 21402-00 to bleed off air to system. Daily Maintenance 2. Open P/N 21228-00 on catalyst pump to recirculation position. It is recommended that the following service be performed on a daily basis. 1. The Gun is built at the factory with, P/N 21222-00 Lubricate. This is a water soluble lubricate, not affected by most solvents.

(such as humidity) to form small, hard, abrasive crystals, which become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity. If used, this partially cured ISO will reduce performance and the life of all wetted parts. Maintenance The amount of20507-00 film formation and rate of crystalli-6. a.
Maintenance Needle & Pin Reassemble Procedure 1. Reassemble the needle assemblies to the gun body. Lubricate the o-rings & use teflon tape on the threads. 2. Make sure the gun pins are lubricated and slide them into the gun block and can be seen between the gun block and the back side of the trigger and they both are exposed at the back of the gun block near the catalyst and resin needles. 3. Lock-tite both of the set screws, then assemble them to the needle guard using a 5/64in.
Maintenance Trigger & Needle Guard Readjustment Procedure If you trigger the gun and notice that one needle is activating before the other and not parallel, fine adjustment is needed. 1. Using a 5/64in. hex key adjust the Set Screw which is NOT making gun pin contact when the gun is triggered. Turn the set screw until both needles activate at the same time. Making the needle guard parallel is very important, to prevent LAG-LEAD in the catalyst & resin mix. Set Screws 5/64in.
Maintenance Packing Nut Adjustment Procedure 3 Adjust the packing nuts with a wrench. (3/8in. open end) 1 Remove the trigger from gun. Slide it down and to the side. 2 Slide the gun pins, p/n 23514-00 forward to allow access to the packing nuts.
