Operating Instructions General Safety Instructions METACAP Spray Gun D/A 5 General Safety Instructions 5.1 Risk of Fire and Explosions Caution! Solvents and coating materials may represent a potential risk of fire and explosions. — All dangerous zones must be equipped with an efficient ventilation or suction system to avoid a potentially dangerous accumulation of inflammable vapors. Please observe the respective rules for prevention of accidents "Processing of Coating Materials".
Operating Instructions General Safety Instructions METACAP Spray Gun D/A Caution! It is possible that static electricity may be produced during the spraying procedure. In case of high flow rates, it might be possible that an electrostatic spark is generated by friction. This spark may then ignite certain types of solvents and coating materials. To avoid fire and explosions, a continuous grounding of the spray system and of the object to be sprayed should be ensured.
Operating Instructions General Safety Instructions METACAP Spray Gun D/A 5.3 Noise Level The continuous noise level within the highest performance range of these spray guns may exceed 85 db(A) depending on the adjusted supply air pressure and on the nozzle cap settings. The noise levels are measured by using impulse noise meters under normal operating conditions of the spray gun.
Operating Instructions Description, Structure and Functioning METACAP Spray Gun D/A 6 Description, Structure and Functioning 6.1 Description The METACAP Spray Gun is a low pressure device. The spray material is atomized with low pressure while at the same time being encapsulated by a large volume of air; this air jacket presses the atomized spray material against the surface to be processed and prevents clouds of atomized spray material from escaping.

The METACAP Spray Gun D/A generates the necessary low pressure and the required high air volume from the compressed air produced by the compressor and from the ambient air. The air supply nozzle (1/26) supplies the compressed air into the spray gun, where it is reduced to approx. 0.
Operating Instructions Initial Operation METACAP Spray Gun D/A 7 Initial Operation Note: The position numbers refer to the figure 1, see chapter 6.2 Structure of the METACAP Spray Gun D/A, page 6-11. Important note: To ensure that no residual matters have a negative effect on the spray results, use an appropriate solvent to thoroughly rinse the METACAP Spray Gun D/A before initial operation.
Operating Instructions Operating Instructions METACAP Spray Gun D/A 8 Operating Instructions Note: The position numbers refer to the figure 1, see chapter 6.2 Structure of the METACAP Spray Gun D/A, page 6-11. 8.1 Attention! — Mix, condition and filter the coating material to be sprayed according to the instructions of the manufacturer. — Fill the material container with the coating material taking into account the maximum filling height indicated by the manufacturer.
Operating Instructions Operating Instructions METACAP Spray Gun D/A — 5. Turn the screw as long as the required coating material quantity becomes visible. Now move the spray gun to and fro in front of the work piece and ensure a vertical spray beam, if possible (see figure 2). Figure 2: Attention! Guiding of the METACAP Spray Gun D/A Intensive waving will cause the air jacket will become unstable, allowing clouds of atomized spray material to escape. 6.
Operating Instructions Operating Instructions METACAP Spray Gun D/A Figure 3: Attention! Spray Beam Shape Adjustment 7. Adjust the width of the spray beam by using the nozzle cap adjusting ring (1/1) to modify the distance between the nozzle cap (1/2) and the nozzle (1/4). — turn clockwise – wide spray beam — turn counterclockwise – narrow spray beam Never tighten the nozzle cap adjusting ring too firmly.
Operating Instructions Operating Instructions METACAP Spray Gun D/A An infinite number of variants are possible between the indicated settings 1, 2, and 3. The quantity of coating material coming out of the spray gun can be adjusted by turning the knurled screw (1/38). Attention! — counterclockwise: more material — clockwise: less material Please, take into account that you always adjust the material quantity simultaneously when modifying the width or shape of the spray beam.
