back into the thinner container. Wipe off the exterior of the Spray Gun with thinner to remove paint. If the gun becomes clogged, disassemble 4. parts 1 - 7, 9 -12 and 26 - 30 and carefully clean all the parts. To clean, use the enclosed brush (33) 5. or a cleaning kit, such as SKU# 99634 available from Harbor Freight Tools. Never use a pin or metal scraper to 6. clean the delicate components of this sprayer. You will damage the sprayer. Carefully reassemble following the 7. Assembly diagram on page 17. Be sure all springs and seals are properly seated. Do not damage threads. Do not overtighten. Tool Troubleshooting Problem Possible Causes Likely Solutions Decreased output. Not enough air pressure 1. and/or air flow. Obstructed trigger. 2. Blocked air inlet screen (if 3. equipped). Air leaking from loose 4. housing. Air Regulator set too low.5. Check for loose connections and make sure 1. that air supply is providing enough air flow (CFM) at required pressure (PSI) to the tool’s air inlet. Do not exceed maximum air pressure. Clean around trigger to ensure free 2. movement. Clean air inlet screen of buildup. 3. Make sure housing is properly assembled and 4. tight. Adjust Air Regulator setting.5. Severe air leakage. (Slight air leakage is normal, especially on older tools.) Cross-threaded housing 1. components. Loose housing. 2. Damaged connectors or 3. housing. Check for incorrect alignment and uneven 1. gaps. If cross-threaded, disassemble and replace damaged parts before use. Tighten housing assembly. If housing cannot 2. tighten properly, internal parts may be misaligned. Replace damaged components.3. Inconsistent paint flow, blobs and splatters Clogged Air Cap (1) or 1. damaged Fluid Nozzle (2). Clogged Paint Filter (27).2. Damaged or dirty Paint 3. Needle (9). Contaminated paint.4. Clean , adjust or replace Air Cap or Fluid 1. Nozzle. Clean Paint Filter (27).2. Clean, repair or replace Paint Needle (9). 3. Remove paint and filter it.4. Paint blows out too hard Air pressure set too high.1. Adjust Air Regulator to no more than 45 PSI. 1. Fine tune air pressure using Air Adjustment Valve (31). Follow all safety precautions whenever diagnosing or servicing the tool. Disconnect air supply before service. Paint Application TroubleShooting Problem Possible Causes Likely Solutions Paint surface is bumpy or “orange peeled” Paint is applied too thick 1. Incorrect paint volume2. Insufficient air pressure 3. Paint gun too far from paint 4. surface during spraying Paint must be thinned properly 1. before spraying Adjust Fluid Control Knob (12)2. Adjust Air Regulator (37) and Air 3. Adjustment Valve (31) Hold spray gun closer to surface 4. during spraying. Paint sags or runs Excess thinning of paint 1. Paint applied too thick 2. Paint gun too close to work 3. surface Uneven or hesitant motion of 4. spray gun Excess overlapping of each 5. spray stroke Excessive paint fluid6. Recheck paint viscosity. Add 1. unmixed paint to thicken mixture. Apply thinner coats, allowing paint 2. to get tacky between coats. Move spray gun further back from 3. paint surface when applying paint. Keep spray gun moving during 4. painting. Hesitations can cause sags or runs. Overlap each stroke to keep the 5. coverage even, but be aware that you are adding coat thickness by overlapping. Adjust the Fluid Control Knob (12)6. Blotchy surface (blushing) or uneven color Paint dries too fast1. Uneven paint application 2. Work material absorbs paint 3. unevenly Use less thinner or add a drier.1. Start each stroke off the work 2. material and overlap each stroke consistently. Use a conditioner or sealer coat 3. before applying the finish coat. Spots on surface with light center (fish eyes) Paint mixture too thin 1. Improper primer or 2. incompatible surface Surface contamination3. Add undiluted paint to thicken 1. mixture Check manufacturer’s 2. recommendations for primer or compatible surfaces Clean surface thoroughly with 3. thinner before applying paint Spots on surface with dark center (contamination) Dust or dirt on surface 1. Insufficiently sanded 2. Raised grain3. Clean surface with compressed air 1. or tack cloth before painting Sand wood to a sufficiently fine grit 2. before painting. Wipe wood surface with thinner to 3. raise grain, then sand with fine grit to knock of “hairs” PARTS LIST Part Description Q’ty 1 Air Cap with Lock ring 1 2 Fluid Nozzle 1 3 Air Ring 1 4 Piston Pad 1 5 Compression Ring 1 6 Needle Seal Spring 1 7 Air Piston Seal 1 8 Gun Body 1 9 Paint Needle 1 10 Paint Piston Spring 1 11 Lock Nut 1 12 Fluid Control Knob 1 13 Air Piston Box 1 14 Air Piston Packing 1 15 Air Piston 1 16 Piston Ring 1 17 Air Piston 1 18 Air Piston Spring 1 19 Spray Regulator Screw 1 20 Spray Regulator Knob 1 21 Screw 1 22 Trigger Bolt 1 23 Locking Plate 1 24 Bolt 1 25 Bolt 1 26 Paint Connector 1 27 Filter 1 28 Cup 1 29 Lid 1 30 Vent 1 31 Air Adjustment Valve Assembly 1 32 Air Inlet 1 33 Brush 1 34 Hex Adapter 1 35 Wrench 1 36 Trigger 1 37 Air Regul...
