17 Using the Sander CAUTION: Always wear ANSI approved safety goggles and full face shield, with dust mask or respirator while sanding. 1. Be sure all safety precautions are being followed. 2. Tighten workpieces to your workbench or other fixed base so that both of your hands are free to hold the Sander. 3. Set the air compressor regulator to 90 psi. Connect the Air Sander to the air compressor hose at the Air Inlet (2C). Use the Air Regulator (19C) to adjust the air pressure as required. 4. Check to be sure all attachments are secure before turning on the tool. 5. Grip the handle with one hand, and the Housing (1C) with the other. Depress the Trigger (16C) to turn the tool on. Allow the motor to reach its full speed before sanding. Be sure the tool is operating properly, and running smoothly before proceeding. 6. Apply the sanding pad to the work material at a slight angle. Move the sanding pad around the surface of the work material as needed. Do not allow the pad to remain in one place as this may burn the work material. If the sander slows down appreciably, you are applying too much pressure. Always keep your body and clothing away from the moving sanding pad. 7. When you are done sanding, remove the tool from the work material, and release pressure from the Trigger (16C). Allow the tool to come to a complete stop before setting it down. Disconnect the air pressure hose when the tool is not in use. Some Tips About Sand Paper 1. When sanding, start with a relatively coarse grit paper, and work up to a finer grit to complete the job. The grit selected depends on the job at hand. With bare metal finishing, you may start at 100 and work up to 600 grit. With paint finishing, you may start with 400 and work up to 2000 grit, for example. Your choice of grit depends on the job and your preferred method of working. NOTE: Harbor Freight Tools cannot be responsible for damage to property due to incorrect selection of sanding disc or grit size. Always practice on scrap material before using the tool on your workpiece. 2. Sand paper works by moving a large number of sand grains in an arbitrary pattern over the work surface. Because of the Backing Pad, these will produce a relatively uniform series of hills and valleys at the grain size of the grit used. Using the first grit selected, sand out any scratches or blemishes in the finish. You want to produce an even finish at the grain size of the grit being used. NOTE: Your Sander features an Air Regulator (19D), allowing you to vary the amount of air pressure to the tool. Turn the regulator knob clockwise to increase the air flow, counterclockwise to restrict it. SKU For technical questions and replacement parts, please call Page 17 REV 02/07
