AIR SUPPLY 4.1. Ensure that the air valve is in the "off" position before connecting to the air supply. 4.2. The spray gun will require an air pressure of approximately 60psi and an air volume of more than 12cfm. WARNING! Ensure the air supply is clean does not exceed 90psi. Too high an air pressure and unclean air will shorten the life of the gun due to excessive wear and may be dangerous, causing damage and/or personal injury. 4.3. Drain the air supply tank daily. Water in the air line will damage the gun and contaminate the paint. 4.4. Clean the compressor air inlet filter weekly. For recommended hook-up, see diagram. 4.5. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose bore should be 10mm and fittings must have the same inside dimensions. 4.6. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure. 5. PREPERATION 5.1. The gun was treated with an anti-corrosion agent to protect it prior to first use. Before first use make sure that the gun is flushed with paint solvent to remove the agent. WARNING! Solvents and cleaning agents based on halogenated hydrocarbons, e.g. 1.1.1-trichlorethylene and methylene chloride, may have a chemical reaction with the aluminium components of the gun. In extreme cases the reaction can be explosive. Therefore, use only solvents/cleaning agents which DO NOT contain these substances. 6. OPERATION Ensure that you have read and understood the safety instructions in Section 1 and the warning in Section 4. 6.1. For best results the gun must be handled and operated correctly. It should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke before squeezing the trigger and release the trigger before finishing the stroke. This will enable you to accurately control the gun and paint (fig.1). 6.2. Spray from a distance of about 6 to 10 inches depending on the material and the atomizing pressure. The paint deposited should always be even and wet. Each stroke must overlap the preceding stroke to obtain a uniform finish. To reduce over-spray and obtain maximum efficiency, spray with the lowest effective atomizing air pressure. 6.3 Controlling the fan spray and the paint: a) Use the paint control knob (fig.2.B) to increase or decrease the paint flow. b) The air input control (fig.2.C) should be set to the lowest effective flow. c) Turn the air cap (fig.3.1) to achieve a horizontal or vertical fan spray. Lock the cap with retaining ring (fig.3.2). d) The spray pattern is variable from round to flat with all patterns in between, controlled by the pattern knob (fig.2.A). e) In normal operation, the wings on the cap are horizontal as (fig.3). This provides a vertical fan-shaped pattern (fig.4) which gives optimum coverage when moving the gun back and forth, parallel to the work surface. fig.2 fig.1 fig.3 fig.4 © Jack Sealey Limited Original Language Version S775 | Issue 3 (H,F) 27/11/18 7. MAINTENANCE 7.1 7.1.1. 7.1.2. 7.1.3. 8 7.1.4. 7.1.5. 7.2 7.2.1. 7.2.2. CLEANING IT IS VERY IMPORTANT TO ENSURE THAT THE GUN IS CORRECTLY CLEANED AFTER EACH USE Disconnect from the air supply before attempting any cleaning, other than flushing, or maintenance. Flush the gun thoroughly with solvent and clean the nozzle with solvent and a brush. DO NOT immerse/soak the nozzle in solvent. DO NOT immerse the entire gun in solvent. This will cause lubricants to dissolve and packing to dissolve or dry out. Wipe the outside of the gun with a solvent-dampened rag. If you need to clear blocked orifices, be sure to use a probe that is softer than brass. Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check that you have the correct part, or unscrew, realign and try again. DO NOT use excessive force when re-assembling. Lubricate the gun daily with a light machine oil. Be sure to lubricate the fluid needle packing, air valve packing and trigger pivot point. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in. 8. TROUBLESHOOTING A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air cup - use a brush and solvent to remove. Never use metal instruments to clean the air cup or paint nozzle. These parts are carefully machined and any damage to them will cause a faulty spray. If either the air cup or paint nozzle is damaged, the part must be replaced before a perfect spay can be obtained. PROBLEM POSSIBLE CAUSES Dried material in a side port restricts passage of air. Greater flow of air from the clean side port forces a fan pattern in the direction of the clogged side. SOLUTION Dissolve material in the side ports with solvent, then blow the gun clean. Do not poke into the nozzles with metal instruments. Paint spray `flutters' Material bubbles or "boils" in paint cup. Dried material around the outside of the fluid nozzle tip restricts the passage of atomizing air at one point through the centre opening of the air cup and results in the pattern shown. This pattern can also be caused by a loose air cup. A split spray or one that is heavy at each end of the fan pattern and weak in the middle is usually caused by too high an atomization air pressure or by attempting to get too wide a spray with thin paint. Remove the air cup and wipe off fluid tip using a rag dampened with solvent. Tighten the air cup. Dried material in a dirty side port restricts passage of air. Greater flow of air from the cleaner side port forces a fan pattern in the direction of the clogged side. 1. Worn needle packing permits air to get into the fluid passageway. This results in spitting. 2. Dirt between the paint nozzle seat and body or a loose paint nozzle will cause the gun to spit. 3. A loose or defective joint between the pot and gun can cause spitting. 1. Tighten the packing screw or, in severe cases, replace the packing. 2. Remove the fluid nozzle, clean the back of the nozzle and the nozzle seat in the gun body using a rag dampened with solvent. 3. Tighten or replace. Atomised air flowing through the paint channel to the bottle. The paint nozzle is not sufficiently tight. Air nozzle is not completely screwed on. Tighten, clean or replace parts accordingly.
