SKU For technical questions, please call Page 8

9 Grounded Tools: Tools with Three Prong Plugs Double Insulated Tools: Tools with Two Prong Plugs Tools marked with Grounding Required have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock. (See 3-Prong Plug and Outlet.) The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool s grounding system and must never be attached to an electrically live terminal. (See 3-Prong Plug and Outlet.) The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong Plug and Outlet.) Tools marked Double Insulated do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Outlets for 2-Prong Plug.) Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See Outlets for 2-Prong Plug.) Extension Cords Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.) SKU For technical questions, please call Page 9

10 The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.) When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Table A.) If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.) If you are using an extension cord outdoors, make sure it is marked with the suffix W-A ( W in Canada) to indicate it is acceptable for outdoor use. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.

Loosen the Guard (24B) on the Spray Gun. Align the Guard horizontally to obtain a horizontal spray pattern. Align the Guard vertically to obtained a vertical spray pattern. NOTE: MUST BE METAL BUCKET OR CONTAINER. FIGURE B Spray the paint into the container to relieve the system pressure. Lock the Spray Gun by turning the Safety Lock to the locked position. Turn the Prime/Spray Knob (39A) to its PRIME position. 1. 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 scrap material before beginning to paint your workpiece. SKU For technical questions, please call Page 14

15 2. 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. Properly mask your paint surface from any adjacent areas you do not want to paint. Use drop cloths or other covers to protect adjacent objects from paint dust or overspray. In most cases, it is best to move the paint spray from side to side, overlapping the previous paint. 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 Spray Gun away from the workpiece, squeeze the Trigger to start the spray. Then move the Spray Gun in to within inches of the workpiece. Move the Spray Gun smoothly across the workpiece, keeping a consistent distance. At the end of each stroke, pull the Spray Gun away from the workpiece as you release the Trigger. As you work, 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 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 scrap material before resuming work. Maintenance And Servicing Procedures not specifically explained in this manual must be performed only by a qualified technician. To prevent serious injury from accidental operation: Prior to cleaning, lock the Trigger. Turn the Pressure Adjust Knob (69A) to OFF. Then open the Prime/ Spray Knob (39A) to release all pressure. Prior to storing or performing service and repairs, turn the Power Switch (33A) of the Sprayer to its OFF position, unplug the Sprayer from its electrical outlet, and relieve pressure from the system. To prevent serious injury from tool failure: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use. BEFORE EACH USE 1., inspect the general condition of the Airless Sprayer. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, damaged hoses, and any other condition that may affect its safe operation.
