REMARKS This is a “closed coat” belt and has a white colored backing for identification. The abrasive used is aluminum oxide. Similar to above belts but “open coat”. Aluminum oxide grits are wider apart.

Sanding Tips TECHNIQUE Grasp the handles firmly. Start the sander with the belt off the work (NOTE: never start or stop the tool with the belt in contact with the work surface). Place the heel of the sander on the work first. Then, with a forward motion, begin the sanding stroke as the machine is lowered onto the work surface. This will prevent gouging. Keep the sander moving so that your work will be smooth and even. The stroke is simply a back-and-forth movement with most of the sanding done on the pull movement. Use a light touch. The weight of the belt sander is the only pressure required. Too much pressure will slow the work by overloading the motor and reducing belt speed. The result will be decreased sanding efficiency. Sand slowly and systematically and, when you stop, lift the sander from the surface before stopping the tool. WOOD FINISHING Take care to select belts wisely. For initial smoothing of rough lumber, use coarse or very coarse grit and sand with the grain. On very uneven or hard wood, sand diagonally (across the grain). Be careful to avoid gouging. Now switch to medium grit belt and sand with the grain. This will provide a relatively level and smooth finish. Now insert a fine grit belt for final finishing. Always sand with the grain to remove scratches left by coarser belts. Keep the sander moving in long, light strokes during finishing operations. As a final touch, experienced sanders will often insert a “used” fine belt to provide a smooth surface for filling, sealing, brushing or spraying. REFINISHING COATED WOOD Your belt sander will also help remove old paint, varnish or lacquer; however, if the coating consists of several layers, remove as much as possible with a paint solvent or varnish remover before using the belt sander. Use a hand scraper to remove the residue left by the solvent and allow surface to dry completely before sanding. GUIDE FOR WOOD SANDING OPERATION SANDING OPERATION PURPOSE ABRASIVE TO USE METHOD OF SANDING ROUGH To level out uneven surfaces. Open Coat Coarse Grit Sanding diagonally to start and finish up sanding parallel with the grain. PREPARATORY To smooth the rough sanding preparatory to finish sanding. Open Coat Medium Grit Sanding parallel with the wood grain. FINISH The last sanding in preparing the bare wood for coating. Open or Closed Coat Fine Grit Sanding parallel with the wood grain. Remove all sanding dust thoroughly before coating. Use a soft brush or a vacuum cleaner and hose to remove all dust from seams or crevices. For fast removal, start with a coarse grit, open coat belt. Change to closed coat belts, using medium grits as the material shows through the coating. When the covering is thin, use medium grit to avoid scratching the material. Use short, light strokes, moving the sander rapidly. Excessive pressure or steady sanding in one place will burn the coating and load the belt. METAL FINISHING For ferrous metals such as steel, stainless steel, iron, etc., use coarse grit open coat belts or coarse to fine grit closed coat belts, depending on the finish desired. Non-ferrous metals such as aluminum, solder, brass, bronze, etc., can also be sanded. Beeswax or tallow are recommended as lubricants for metal sanding, polishing or satin finishing to minimize belt loading and to lengthen belt life. To use, simply rub the lubricant on the belt from time to time. SAE No. 10 or 20 lubricating oil can also be used to assure a smooth scratch free surface. Just wipe the oil on the surface prior to sanding. -9 SM 2610929106 3-05 3/15/05 10:33 PM Page 10 Maintenance Service Preventive maintenance performed by unauthorized !WARNING personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Skil Factory Service Center or Authorized Skil Service Station. TOOL LUBRICATION Your Skil tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change. CARBON BRUSHES The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brushes be examined. Only genuine Skil replacement brushes specially designed for your tool should be used. BEARINGS After about 300-400 hours of operation, or at every second brush change, the bearings...
