DeVilbiss JGA Decorator

Inside This Document

Service manual SB-2-582 for the DeVilbiss JGA-510-DEC decorator gun — a JGA configured to apply decorative spatter effects to wood furniture, metal panels, and similar surfaces. Finish texture changes from fine mist to large droplets simply by adjusting fluid and/or air pressure, and the gun ships with the flat-end AV-447 spatter air cap. The 8 pages cover setup, operation, and service parts (JGA-4040, MBC-231 components) for decorative finishing work.

DESCRIPTION The JGA-510-DEC is a gun that can ap - ply decorative spatter effects to wood furniture, metal panels, etc. Finish may be changed from a fine mist to larger droplet size particles. Simply adjust fluid pressure and/or air pressure The JGA-510-DEC comes with the flat- end AV-447 spatter cap assembly. Small spatter dots are the result of coarse atomization when using the standard spatter cap assembly (2). OPERATION NOTE This gun may be used with chlorinated solvents. Aluminum is not used in the fluid passage areas. Mix material according to manufacturer's instructions. It may be necessary to strain material. A greater than normal gun distance provides a more uniform particle size. Particle spacing is determined by speed of movement and degree of overlap. Particle size is dependent on the material consistency. Specially formulated spatter materials are available, although stan - dard paints may be used. Apply standard paints using very little or no reduction. Pressure on cup or tank controls material flow. Begin with the fluid needle adjusting screw (32) wide open. Use fluid needle adjusting screw (32) to regulate material flow under abnormally low material pressure or material viscosity conditions. Adjust atomization air to get desired particle size. It should be high enough to carry particles to surface. Spatter dot size increases with pressure reduction, and decreases with pressure…
