12.Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you are tired.

13.Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if the trigger does not operate properly.

14.Replacement parts and accessories. When servicing, use only identical replacement parts. Use of any other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories are available from Harbor Freight Tools.

Assembly

First, prepare your air supply.

1.This tool operates within a pressure range of 20 - 45 psi, and consumes 5.5 CFM of air at 45 psi. Provide yourself with a compressed air supply which will meet these requirements. Air compressors and related supplies are available from Harbor Freight Tools.

2.For best results, arrange your compressed air supply to include a filter and regulator as indicated in the schematic diagram above. The addition of quick connect air valves, reel and other features will enhance

Operation

1.Prepare the work piece to be painted according to paint manufacturer???s directions. Prepare your paint mixture according to paint manufacturer???s directions. NOTE: In most cases, paint must be thinned for proper spraying. Be sure to use a thinner recommended by the paint manufacturer.

2.Fill the Paint Cup (35) no more than 2/3 full with your paint mixture. Screw the Reservoir into the Reservoir Cap (32) being sure the Reservoir Seal (33) is in place.

3.Turn on your air compressor, and adjust the regulator to the recommended pressure (20 - 45 PSI).

4.IMPORTANT: Before applying paint to your work piece, test spray a piece of scrap material. In most cases both the paint mixture and spray pattern will have to be adjusted for best results.

5.To spray, squeeze the Trigger (26), as you move the Sprayer past the work material. Release the Trigger (26) at the end of each pass. Repeat until you have proper paint coverage of the work piece.

6.When you have completed painting your project, disconnect the Sprayer from its air pressure source and immediately clean following the directions in the Maintenance section on page 8.

Painting Tips

Successful spray painting is a skill which requires knowledge of your equipment, familiarity with your paint materials and experience. Differences in paints, work materials and environmental conditions make every painting task unique. For best results, practice with your painting mixture on a scrap piece before beginning to paint your work material.

It is critical that the surface be properly prepared before painting. It will be difficult to achieve a satisfactory painted surface if the original surface is dirty, rough or wet.

Paint Mixture:

Each paint mixture will vary. You may use solvent or water based paints. Each of these causes a different paint viscosity, and has a different flow rate and drying time. High viscosity is thick, like syrup. Low viscosity is thin, like water.

The purpose of the solvent is to make the paint liquid so it can be applied. Once applied, the solvent evaporates, leaving the pigment and its binders in place. The solvent is also used as a clean up medium. Paint mixtures which are to be sprayed are generally less viscous (thinner) than mixtures which are to be applied with a brush. Thus you will most often have to add extra solvent to a paint which is to be sprayed.

When paint is sprayed, it is broken into tiny droplets, then blown by high- pressure air onto the surface. During this spraying process, the surface of each paint droplet will begin to dry. When it hits the work material, the droplet must liquefy again, and mix with the droplets hitting alongside it. Ideally, these droplets will mix evenly forming a smooth surface.

If the paint mixture is too thick, the droplets will not form a smooth layer, and the resulting surface can be described as ???pebbly??? or ???orange peel???. If the paint mixture is too thin, the paint will run, forming long drips before they are thick enough to form a satisfactory coat. Vertical surfaces are more prone to ???run??? than horizontal surfaces due to the effect of gravity.

Applying the Paint:

In most cases, it is best to move the paint spray from side to side, over- lapping the previous paint. In this way you will gradually build up the paint layer without leaving any obvious edges.

To paint in this way, the spray pattern should be set to vertical.

It is important to prevent excess paint at the beginning and end of each stroke. Holding the sprayer away from the work piece, squeeze the trigger to start the spray. Then move the spray gun in to within 14-16 inches of the work piece. Move the sprayer smoothly across the work piece, keeping a consistent distance. At the end of each stroke, pull the sprayer away from the work piece as you release the trigger.

As you work, carefully observe the way the paint accumulates on the work surface. It is more important to maintain a good paint surface than to form an opaque (thick) paint coat.You can always apply a second coat to get the coverage you want. If the surface is ruined, however, you will have to start over with surface preparation.

If the surface does not smooth out in a few seconds after applying the paint, your paint mixture is probably too thick. Thin your paint slightly and test on a piece of scrap material. If the paint goes on very thin and threatens to run, stop spraying immediately. Add more paint to your mixture to thicken the paint. Test on a piece of scrap material before resuming work.

HOW TO ADJUST PAINT FLOW AND AIR PRESSURE

To adjust the spray pattern, loosen the Nozzle Lock Ring (1) by turning it counterclockwise, then rotate the Air Nozzle (2), then retighten the Nozzle Lock Ring (1). For a vertical spray pattern, the ???ears??? of the Air Nozzle (2) should be horizontal. For a horizontal pattern, the ???ears??? should be vertical. In other words, the position of the Air Nozzle and the spray pattern are opposite.

Further adjustment of the spray pattern may be made by adjusting the Spray Control Knob (27).

Maintenance

After each use, thoroughly clean the spray gun.

1.Empty the Paint Reservoir of paint, and wipe it out with a clean rag.

2.Fill the Paint Reservoir about half way with the solvent which is appropriate for the paint you have sprayed.

3.Spray the solvent into an appropriate receptacle for proper disposal. Continue to spray until paint in the interior of the Spray Gun is ejected and the solvent spray is clear.

4.Using a clean rag wetted with solvent, wipe off the Spray Gun to remove paint from the exterior.

5.Store your paint sprayer in a clean dry place.
