Type HP – 68 spray guns are easier to use than most spray guns. These lightweight gravity feed spray guns are suitable for production work on articles of medium or large sizes. They are ideal for spray-painting motorcar bodies, refrigerators, machinery, etc. Perfect balance, comfortable handle and trigger action makes them easy and non-tiring to operate. A knob on the left can easily control round to fan spray of pattern. These gravity feed spray guns are supplied with a 0.15 lit. gravity cup.<\/p>\n
INSTALLATION of Pilot Spray Gun Type 68s
\nIMPORTANT: To ensure that this equipment reaches you in first class condition, protective coatings, rust inhibitors, etc. have been used. Flush all equipment through with a suitable solvent before use to remove these agents from the material passages. Attach the air supply line to the air intake connector (26). An air transformer installed as close as possible to the gun will provide filtered and regulated air. Recommended air hose sizes:
\nAttached air hose connector from a filtered regulated air supply. Recommended air supply hose size up to 10meters long (1\/4\u201d) bore. Attach the gravity feed cup to the material inlet and ensure that the sealing washer is compressed.<\/p>\n
OPERATION for Pilot Spray Gun Type 68s
\nMix, prepare and strain the coating material to be sprayed according to the paint manufacturers instructions. Use a lint free mesh to strain the material. Fill the gravity feed cup with the material. Do not overfill. Ensure that the vent hole in the cup lid is clear. Adjust the atomizing air pressure to 1-2.5 kgs\/sq.cm. (14 to 36 p.s.i.). It requires air about (2 – 4 c.f.m.) 55 – 115 liter per minute depending on the liquid to be sprayed.
\nClose the fluid needle adjusting screw by turning clockwise. Turn on the air at the source of supply and spray test area by turning the fluid needle adjusting screw counter-clockwise until a full coat is obtained.<\/p>\n
In the finish is too sandy and dry, reduce the viscosity of the coating material supply by turning the adjusting screw counter-clockwise. Increasing or decreasing the atomizing air pressure can also correct both the above. The most efficient atomizing air pressure is the lowest possible air pressure that will give the desired effect. The gun should be held perpendicular to the spray surface at all times. Do not arc the gun as this produces and uneven coat of paint. The recommended spraying distance is between 230mm (9\u201d).<\/p>\n

\nRemove air cap and clean by immersing in solvent, brush or wipe clean. If any holes in the air cap
\nare blocked use a toothpick or broom straw to remove the obstruction. Never use a steel wire or
\nhard implement which will damage the air cap and result in a distorted pattern.<\/p>\n
Lubrication of Pilot Spray Gun Type 68s
\nLubricate all moving parts daily with a few drops of light oil and occasionally place a light coating of
\nVaseline on the needle spring. The packing may need to be oiled occasionally to keep them pliable.<\/p>\n
NOISE LEVELS
\nThe continuous A-weighted sound pressure level of this spray gun may exceed 85 dB (A) depending on the air cap\/nozzle set-up being used. Sound levels are measured using an impulse sound level meter and analyzer, when the gun is being used in a normal spraying application. Details of actual noise levels produced by the various air cap\/nozzle set-ups are available on request.<\/p>\n
