This air pressure usually falls between 40 - 60 psi. Adjust air pressure with trigger pulled and air control knob (if applicable) fully open. If reduced air pressure is desired for some areas of spray job, use air control knob to reduce pressure as necessary (See Figure 3). Before spraying the workpiece, practice a few minutes on a cardboard target to ensure the pattern size and consistency are set correctly. 2 Operating Instructions TL2402 Operation 1. Begin spraying. Always keep the gun at right angles to the work (See Figure 4). Keep the nozzle about 6 to 9 inches from the work surface throughout the stroke and always keep the gun in motion while spraying. Stopping gun movement in mid-stroke will cause a build up of paint and result in “runs.” Do not “fan” the gun from side to side while painting. This will cause a build-up of paint in the center of the stroke and an insufficient coating at each end (See Figure 5). 3. The amount of paint being applied can be varied by the speed of the stroke, distance from the surface and adjustment of the fluid control knob. 4. Overlap strokes just enough to obtain an even coat (See Figure 7). NOTE: Two thin coats of paint will yield better results and have less chance of runs than one heavy layer. 5. Use a piece of cardboard as a shield to catch overspray at the edges of NOTE: In the instructions below, the use of the word “solvent” refers to the specific solvent for the material used (eg: lacquer thinner for lacquer, etc ). 1. Spray guns with canister—Remove and empty the canister; then rinse with a solvent recommended for the paint or other material used. 2. Refill canister with clean solvent and attach to the gun. Spray solvent through the gun while shaking the gun vigorously. Wipe the gun exterior with a solvent soaked rag. Repeat until the gun is clean. 3. Remove the air cap and soak in solvent until clean. Use a small brush for stubborn stains if necessary. Toothpicks or small brushes may be used to clean air passages; however, NEVER USE METAL OBJECTS TO CLEAN PRECISELY DRILLED PASSAGES. DAMAGED PASSAGES WILL CAUSE IMPROPER SPRAYING. 4. Clean gaskets with a solvent soaked rag. To prevent equipment damage, Do not immerse gaskets or spray WATER/OIL IN COMPRESSED AIR All compressor pumps discharge some condensed water, oil or contaminates with the compressed air. IMPORTANT: This condensation will cause “fish eyes” to appear in the paint job. Install appropriate water/oil removal equipment and controls as necessary for the intended application. Failure to install appropriate water/oil removal equipment may result in damage to machinery or workpiece.

Start the gun moving at the beginning of the stroke BEFORE SQUEEZING THE TRIGGER and release the trigger BEFORE STOPPING GUN MOVEMENT at the end of the stroke. This procedure will “feather” (blend) each stroke with the next without showing overlap or unevenness (See Figure 6). the work to protect other surfaces. Use masking tape to cover other areas if needed. Maintenance DAILY CLEAN-UP Local codes may require specific cleaning methods and equipment. Follow local codes and manufacturer’s recommendations for the use and disposal of spray materials and solvent. Clean spray gun immediately after use. Paint and other material dry quickly in the small passages rendering gun useless due to the difficulty of removing hardened paint from the passages inside the gun. gun body in solvents. 5. After using water to clean out water based paints or materials, spray mineral spirits through the gun to prevent corrosion. 6. Use a non-silicone oil on all moving parts when reassembling. Use Vaseline® or light grease on all threaded connections prior to storage. 7. Clean and flush gun thoroughly to neutralize any contaminants corrosive to the spray gun. 3 Operating Instructions TL2402 Maintenance (Continued) CLEANING A GUN USED WITH A PAINT TANK Shut off the air supply to the tank and release the pressure in the tank. 1. Open the vent on the paint tank. If using an external mix air cap, loosen the cap slightly. 2. Reduce air pressure to 10-20 psi. Hold a piece of cloth, wadded in the hand, tightly around the air cap opening(s) and pull the trigger. The air will back up through the fluid tip and force the paint out of the hose and back into the tank. 3. Pour the paint from tank and use solvent and rags to clean. 4. Put enough solvent into the tank to wash the hose and gun thoroughly. Close the tank and spray from the gun until the solvent comes out clean. 5. Remove and blow out the material hose with compressed air to get rid of any trace of solvent in the hose. When blowing out the hose, the open end should be aimed away from any person...
