Become familiar with this tool, its safety instructions, and its operation before beginning any work. Minor or moderate personal injury may result if safety information is not understood or followed. OPERATION INSTRUCTIONS Starting Sander Plug the cord into a 110V outlet. Move the black switch (located at the front of the sander) to the “–” position to turn the sander ON, and move the switch to the “O” position to turn the sander OFF. The sander should run smoothly. Strange or unnatural noises should be investigated and corrected before operating further. If you cannot easily locate the source of an unusual noise or vibration, contact our service department for help. Selecting Abrasive Types ALUMINUM OXIDE abrasives are an excellent choice because they last longer and are sharper than natural abrasives. Selecting Grit Sizes As a general rule, start with a coarse grit size and move through finer grit sizes until you achieve your desired results. Use the list below to define paper grit sizes: • Extra Coarse..............................12-20 • Very Coarse ..............................24-36 • Coarse ......................................40-50 • Medium....................................60-100 • Fine........................................120-180 • Very Fine ..............................220-280 • Extra Fine ..............................320-400 -4 Attaching Abrasives Abrasive sheets can be easily attached with the hook-and-loop system on the pad of your Model H3120 sander. Fit the sheet over the pad so that it covers the entire area, push and slightly twist to make sure the coated abrasive sheet is snug on the pad. Make sure you don’t cover the suction holes. Using the Sander Determine the appropriate grit size for your project and sand the work evenly in the same direction as the grain of the wood. Always keep the sander moving so the finish of your work stays consistent. If you stay in one place too long, then the sander may produce a depression in the wood that will compromise your finish. Sanding across the grain of the wood may be necessary in some cases to remove rough defects. This should be done with caution, however, because it can produce cross-grain scratching that will require further sanding to remove. Change abrasive sheets as soon as the grit becomes dull. You will recognize this when the sander seems to slide across the work without any “bite.” Never apply excessive force while sanding. Your sander will last longer if you let “it” do the work. Using a slight pressure barely greater than the weight of the machine is ideal because you can still maintain control while obtaining a fine finish. H3120 Palm Sander MAINTENANCE General Regular periodic maintenance on your Model H3120 Palm Sander will ensure its optimum performance. Make a habit of inspecting your sander each time you use it. Check for the following conditions and repair or replace when necessary: 1. Loose fasteners. 2. Worn switch. 3. Worn or damaged cords and plugs. 4. Worn or damaged sanding pad. 5. Any other condition that could hamper the safe operation of this machine. Keeping Tool Clean Your Model H3120 Palm Sander will give you years of trouble free service if you keep it clean and free of built-up dust or grime. Ensure that no air passages get blocked. If they do, blow them out with compressed air. WARNING: Wear safety glasses when cleaning tool with compressed air. Plastic parts can easily be cleaned with a damp cloth, but never use water to clean any electrical parts. Solvents should also be avoided on plastic because of the possibility of damage. If possible, use a scraper to remove glue or sap from your work; these elements may hinder the effectivene...
