DeVilbiss AGN-502 Operation Manual

Operation Manual: AGN-502 AUTOMATIC GUN

Important:

Read and follow all instructions and SAFETY PRECAUTIONS

before using this equipment

A lightweight diaphragm operated automatic spray gun for use with ceramic glaze, vitreous enamels, liquid polishing
compounds and similar materials. The standard gun fitted with a rubber diaphragm is not suitable for use with solvent based
coating materials, however it can be converted for use with solvent based coating materials by fitting a PTFE protective
diaphragm see Accessories. Nozzles are available in high grade stainless steel and case hardened Nitralloy steel.

Remotely positioned valves (supplied by user) control the air supplies for atomisation and diaphragm operation. Coating
material supply is by a pressure feed system.

IMPORTANT: These guns are not designed for use with highly corrosive or highly abrasive coating material and if used with
such materials it must be expected that the need for thorough cleaning and/or the necessity for replacement parts will be
increased. If there is any doubt regarding the suitability of a specific material, advise what material is to be used and/or submit
a sample for test.
