3. or servicing A ball valve installed near the spray gun is recommended to stop air supply in case of an emergency and to prevent unintended operation Hazard created while coating materials are atomized and sprayed 1 Toxic vapors produced by spraying certain materials can create intoxication amp serious damage to health Always use the gun in well ventilated areas amp wear protective eyewear gloves respirator etc to prevent toxic vapors solvents amp paint from coming into contact with your eyes amp skin 2 Depending on the noise level due to operation wear ear plugs if necessary Other Hazards 1 NEVER modify this product for any applications 2 NEVER spray foods or chemicals through the spray gun 3 If something goes wrong immediately stop operation and find the cause Do not use spray gun until all problems have been found and solved GENERAL OPERATION Important 1 This gun should only be operated by adequately trained operators 2 Ensure that the spray gun has not been damaged 3 Only clean and dry air should be supplied to the spray gun 4 When using the spray gun for the first time adjust the fluid needle packing set for smooth movement Compressors and Air Pressures Choosing an appropriate air compressor that can supply sufficient pressure for your X1000 spray gun insures optimal operation and performance Working pressures vary from 30 to 50 psi depending on the type of work being done and what textures are
4. desired In general higher pressures are needed to take full advantage of the versatile spray characteristics of the spray gun Viscosity of the paint also effects which pressures are ideal In general larger volumes and or thicker paints require higher pressures Assembling Spray Gun for Use Attach an air hose to the compressor and spray gun Adjust the air pressure according to type of paint used and desired spray characteristics Check for any air leaks from the compressor and or air hose Fill the container with some cleaning solvent and securely attach the container to the spray gun Pointing the spray gun away from you pull back on the trigger to open the nozzle of the airbrush allowing cleaner to spray out Caution The fluid nozzle and needle are very delicate parts Even the slightest physical damage can adversely affect the spray pattern Paint Preparation Proper preparation and filtering of paint through a nylon mesh is recommended for best performance Paint should always be thinned with its proper solvent It is best to prepare the paint relatively thin and make repeated passes across the work to achieve the desired shade This will also improve the quality of your work and decrease the cleaning time of your spray gun Pattern Width Adjustments Pattern widths produced by the spray gun are controlled by adjusting the distance the gun is held from the work surface and adjusting the Fluid Adjustment Knob on the rear of the spray
