EN 77-3047-R1.2 ( 9 /2014) 1 / 8 SERVICE MANUAL MODEL 2100 GW PLURAL COMPONENT SPRAY GUN 2101-XXXX-XGW GENERAL The 2100 GW gun is a lightweight, hand-held, plural compo- nent spray gun for spraying limited applications of two-compo- nent materials, such as gel-coats or polyesters. The spray gun is operated in the conventional manner. The trigger action starts, and stops, the spray of both materials simultaneously. The two materials exit separately as an atomized spray from their respec- tive nozzles and impinge on each other approximately 6" in front of the gun (resin) nozzle. Here, the resulting turbulence insures intimate mixing. The “base” resin is “cured” by addition of a curative (catalyst) in a required ratio. In the 2100 GW gun, ratios of approximately 10:1 to perhaps 33:1 are possible by extending the curative with a compatible diluent. Preferably, the resin should be supplied from a pressure cup mounted either on the gun or located remotely from it. In some applications, a siphon cup may be acceptable. The curative is supplied from a siphon container assembly (57) mounted directly on the gun. Air, diverted from the gun handle, passes through the air adjusting valve (39) to the nozzle body (55) to provide the siphon action and to serve as atomizing air for the curative. The adjustable fluid control (44) meters the flow of curative. SINCE THE CURATIVE CONTAINER IS A SIPHON DEVICE ITS VENT HOLE MUST ALWAYS BE KEPT OPEN. THE VENT HOLE IS LOCATED IN THE COVER AT THE REAR (SEE ILLUSTRATION). NOZZLE CHARACTERISTICS AND SPRAY PATTERNS The 2100 GW gun uses external…
