SAFETYGUIDELINES This manual contains informationthat is importantforyou to know and under_ar_d_ This inforrnation relates to YOU R SAFETY and PREVENTING EQUIPMENT PROBLEMS To help you recognize this information, we use the following symbols Please read the manual and pay attention to those sections, IMPORTANT SAFETY INFORMATION - A HAZARD THAT MIGHT CAUSE SERIOUS INJURY OR LOSS OF LIFE. Information ment. for preventing damage to equip- NOTE Information that you should pay special attention to. HAZARDS WHAT TO LOOK FOR Flammable Spray Materials CAN OCCUR DURING NORMAL USE OF THIS EQUIPMENT. PLEASE READ THE FOLLOWING CHART. WHAT COULD HAPPEN HOW TO PREVENT IT When paints or materials are sprayed, they are broken into very small particles and mixed with air. This will cause certain paints and materials to become extremely flammable Never spray near open flamesor pilot lightsin stoves or heaters. Never smoke while spraying Provide ample ventilation when spraying indoors. Toxic Vapors Some paints and coatings may be harmful if inhaled or allowed to come into contact with skin or eyes Use a mask or resp=rator =fthere =sa chance of inhaling toxic sprayed materials Masks and respirators have limits and will only provide protection against some kinds and limited amounts of toxic material Read mask and respirator instructions carefully. Consult with a safety expert or industdal hygienist if you are not sure about the use of a certain mask or respirator. Compressed Air Compressed air may propel dirt, metal shavings, etc. and possibly cause an injury Never point any nozzle or sprayer toward a person or part of the body_ Always wear safety goggles or glasses when spraying. Pressurized Parts Certain parts are under pressure whenever the gun is connected to a pressurized air line_ These parts may be propelled if the gun is disassembled. Disconnect the gun from the air line, or completely depressurize the air line whenever the gun is to be disassembled. Explosion Hazard Incompatible Materials The solvents 1,1,1-Tdchloroethane and Methylene Chlodde can chemically react with the aluminum used in most spray equipment, and this gun and cup, to produce an explosion hazard Read the label or data sheet for the material you intend to spray. 1 2. 3 Do not use any type of spray coating material containing these solvents Do not use these solvents for equipment cleaning or flushing If in doubt as to whether a material is compatible, contact your material supplier AIR REQUIREMENTS Minimum SCFM required @ 40 PSI 34 GENERAL INFORMATION DESCRIPTION The Craftsman Detail Touch-Up Gun is the only spray gun of its type that can be simply converted for use by a left or right handed sprayer, by simply unscrewing the trigger pin, turning the trigger over and re-inserting the trigger pin. The complete Craftsman Detail Touch-Up Gun consists of a detail touch-up gun and 8 oz. (240 cc) suction cup assembled. The detail touch-up gun is a non-bleeder, suction feed, external mix type. The cup has a one half pint capacity. NOTE: This spray gun is designed to spray stains, acrylics, lacquers, primers, automotive metallics and other light and medium viscosity finishes Most unreduced latex or other heavy bodied materials require the use of a pressure feed paint tank. If used with corrosive, rust-inducing, or highly abrasive materials, frequent and thorough cleaning will be reqt,ired and/or may increase the need for replacement parts. INSTALLATION (Figure 1) Attach nut of paint cup assembly to 1/4" NPT fluid inlet nipple on spray gun, Tighten only until snug, Position yoke at right angle to gun body with cam toward front of gun, Connect atomization air line to air compressor., PREPARING PAINT Be sure the surface to be sprayed is dry and free of all dirt, grease, oil and loose paint Mix and prepare paint in" accordance with the manufacturer's instructions. Strain material to be sprayed through a 60 to 90 mesh screen or VlSCOSIM_R f'_ 0 . ='_"_ equivalent OPERATION This Craftsman Detail Touch-up gun should be flushed with solvent prior to spraying with paint A. Adjust air pressure to approximately 30 P.SL The use of an air regulator assures clean, dry air. B. Turn needle adjustment screw (18) out until first thread shows This places the tip and needle in a full open position which gives maximt,m tip and needle life. Never turn all the way in, as triqqer cam will break. C. Turn fan adjusting screw (1) out until first thread shows D. Press trigger and adjust needle adjt, sting screw (18) for desired material flow. E. Press trigger and observe atomization of fluid If it is too great, decrease air pressure at regulator If it is not enough, increase air pressure at regulator F. Press trigger and adjust fan adjusting screw (I) until desired pattern is obtained A perfect pattern is a full, even coat from end to end Each time needle adjusting screw is adjusted Step E should be repeated CONTROLLING THE FAN SPRAY (Figure 2) The fan spray for an external mix nozzle set up is easily controlled by means of the fan adjusting screw (1) By turning to the right (clockwise) until it is closed will give a rounded spray; turning it to the left (counterclockwise) will widen the spray into a fan shape of any width desired The direction of the fan spray (horizontal or vertical) is obtained by turning the air nozzle to the desired position, then tightening the air cap/ retaining ring (24) Tighten only finger tighL Do not use pliers or wrench to tighten or loosen ® HORLZONTAL FAN ® 0 VERTICAL FAN FIGURE2 CONTROLLING THE FLUID If a fluid pressure tank is used, the amount of fluid can be controlled by regulating the pressure on the tank The amount of fluid can also be controlled by means of the fluid needle adjusting screw (18). By turning it clockwise (to the right), the amount of fluid is reduced Turning it counterclockwise (to the left) increases the amount of fluid. HINTS FOR GOOD SPRAYING TECHNIQUES At all times hold the spray gun perpendicular to the surface being sprayed. A spraying distance of 6-8 inches is recommended. This distance can be varied depending on the item being sprayed, the material or the air pressure used Release the trigger at the end of each lateral stroke while the gun isstill traveling Start the gun moving at the beginning of the next stroke so the gun is in motion when the trigger is pressed (see illustration) This action should be practiced until a smooth, steady, rhythmic stroke becomes natural sunt_,_£ kk\\\\\\\\\ \\\\\\ \\\\\\ \\\\\\_\_ Overlap each stroke 50%. This is done by aiming the gun at the edge of the last stroke. A short practice period will be necessary to achieve an even stroke. Avoid arching the gun as this will leave an uneven coat of paint (see illustration). DON'T ARC fSU _-,,,-, CLEANING R FAC_ o U * LD ta p AND PREVENTIVE MAINTENANCE Preventive maintenance should head off some problems commonly encountered. Remember your detail touchup gun is precision engineered and proper maintenance can help you get the fine quality results you desire To Clean Gun: Spray a small amount of clean solvent through the gun Never immerse the gun in solvents as this removes lubricants and dries out the packings A caustic solution should net be used to clean gun, as this will destroy the aluminum alloy Remove air nozzle (23) and wash it in solvent, If necessary to clean air nozzle holes, use a broom straw or toothpick.. Never use a steel wire or hard instrument as this A will result in distortion of spray pattern. Wipe exterior of gun with solvent soaked cloth Never soak gun in liquid detergent ROUND U To Lubricate gun: After each day's use place a drop of oil at trigger screw (9), fan control packing (3), and fluid needle packing (12), Occasionally remove fan control spring (5) and recoat with a light grease or Vaseline. I FAN MAINTENANCE Proper adjustment of your Craftsman Detail Touch-Up Gun will give you a normal spray pattern of this shape (see illustration) If not, consult service check list on next page, NOTE: If water is used as a solvent clean the gun, spray paint thinner or mineral spirits through the gun after cleaning to remove any excess moisture and protect parts TROUBLESHOOTING GUIDE PROBLEM CAUSE CORRECTION Heavy top or bottom Material build-up on air cap or fluid tip Partially plugged horn holes, center holes or fluid tip hole_ Determine where material build-up is by inverting cap and test spraying If pattern shape stays in same position, the condition is caused by material build-up on fluid tip_ If pattern changes with cap movement, the condition is in the air cap Pattern' _) i i Heavy right or left side Soak cap or tip in suitable solvent and wipe clean To clean orifices use a broom straw or )attern. ql i' Heavy center pattern, & toothpick. Never use a wire or hard instrument This damages holes and distorts its spray pat.tern. Too much material Reduce fluid flow or increase air pressure.
