Connect the 3/8” ID Air Source Hose to the Spray Gun. 2. Set the air pressure on your compressor to 50 PSI. Do not exceed the maximum air pressure of 50 PSI. 3. Check the air connection for leaks and then disconnect the tool from the air source.

Operation (continued) Paint and Materials Preparation Verify with the paint or materials supplier the percentage of thinning required for use with these Sprayers. Try thinning a small amount and testing the spray action. Thoroughly mix material before testing. Viscosity is the technical term used to indicate the liquidity (thickness or thinness) of the material being sprayed. Viscosity is measured in the number of seconds required for the material to pass through the Viscosity Tester (see FIGURE 1). This sprayer can spray materials with a viscosity range of 10 to a maximum of 60 (DINS). Material with a higher viscosity can be used only with water soluble products (outdoor and indoor wall applications). Use high quality products. FIGURE 1 To test the viscosity of a material: Attach to wall here. 1. Place your finger over the output hole of the Viscosity Meter (4). See FIGURE 1. 2. Fill the Cup on the Viscosity Meter (4) to the top. See FIGURE 1. 3. While holding the Viscosity Meter (4) over the material source can, let go of the output hole and count the number of seconds it takes for it to empty completely. The number of seconds is the viscosity rating. Cup Place finger over hole in the bottom.

Preparing the area 1. Mask all objects you do not want sprayed. 2. Lay the appropriate size Tack Cloth (16) on the floor, and attach Tack Cloths (16) to the surrounding walls. Preparing and Operating the HVLP Gravity Spray Gun Refer to page 5 and the Assembly Drawing on pages 10 and 11. Note: We recommend you practice on scrap material to adjust and become familiar with the Gun. 1. Detach the Plastic Cup (2). Insert a Filter (14) into the bottom of the Plastic Cup (2) with the stem end pointing into the cup. This will prevent dirt and debris from entering the HVLP Gravity Feed Gun (1). 2. Mount the Plastic Cup (2) to the HVLP Gravity Feed Gun (1). Make sure that the Plastic Cup (2) is securely attached. Fill the cup with material that has already been checked for viscosity (see page 6). Close to Cup (2) tightly to avoid leakage. 3. Connect the air source hose to the Air Inlet (19a). Turn on your air compressor. Do not exceed the 50 PSI maximum. 4. Pull the Trigger (20a) slowly and move the Spray Gun in parallel strokes to the object being painted. Keep the distance from the object being painted at 4” to 12”. This may slightly differ depending on the flow adjustment and the material being sprayed. 5. Release the Trigger (20a) after each forward movement; pull the Trigger (20a) again on the return movement. 6. When using a vertical pattern, move the Spray Gun in a horizontal motion; with a horizontal pattern move the Spray Gun in a vertical motion. A round pattern requires a greater distance from the object being painted. 7. When finished, release the Trigger (20a) and disconnect from the air source. The Plastic Cup (2) and Spray Gun may still hold air pressure, fire the Spray Gun toward scrap material until all of the pressure is expended. Open the Cap on the Plastic Cup (2) before removing the Lid. Note: Gun adjustments on page 8. Page 7 SKU 90985 Operation (continued) Operation (continued) s Refer to page 5 and the Assembly Drawing on page 11. Note: We recommend you practice on scrap material to learn the fine tune adjustments. 1. To change the spray pattern, turn the Spray Pattern Adjust Knob (4a). 2. To regulate the amount of material entering the Spray Gun, adjust the Fluid Adjust Knob (11a). 3. To fine tune the air flow, adjust the Air Adjust Knob (17a). Preparing and Operating Touch-up Gun Refer to page 5 and the Assembly Drawing on pages 10 and 12. Note: We recommend you practice on scrap material to adjust and become familiar with the Gun. 1. Detach the Plastic Cup (6). Fill the cup with material that has already been checked for viscosity (see page 6...
