The discs vary as to size and spacing of the abrasive grits. OPEN COAT (type H) — used for soft materials and on paint or varnish. CLOSED COAT (type K) —used for metal, hardwood, stone, marble and other materials. Sanding discs range in grit from 16 (very coarse) to 180 (very fine). To obtain best results, select sanding discs carefully. Many SANDING TIPS jobs require the use of several grit sizes and For best results, tilt the Disc Sander at a 10° at times both “open coat and closed coat” to 15° angle while sanding so that only about discs are required to get the job done faster. 1" of the surface around the edge of the disc See chart for application examples. contacts the work. Operation: Refinishing painted wood or metal surfaces. REMARKS GRIT To remove paint and to smooth surface irregularities. Coarse 16-24-30 To smooth the rough sanding. Medium 36-50-80 To remove scratches left by previous discs. Fine 100-120 To smooth surfaces for painting, polishing or waxing.

If sander is tilted too much, sanding action will be too great and a rough cut surface or gouging and snagging will result. Guide the Disc Sander with crosswise strokes. Be careful not to hold the sander in one spot too long. Do not use a circular motion, as this makes swirl marks. Test before use on scrap stock. Do not force or apply pressure when sanding. Use only the weight of the tool for pressure. Excess pressure actually slows the tool down. If faster stock removal is desired, change to a coarser grit disc. Remove gummy paint from metal with an “open coat” disc. Sand until sparks start to appear, then stop and change to a “closed coat” disc to remove any remaining paint. SANDING WOOD When sanding wood the direction of the disc motion at the contact point should parallel the grain as much as possible. The rapid cut of discs and the swirl type scratch pattern they occasionally create generally prohibit their use for producing the final finish. Scratches and circular marks are usually the result of using too coarse a grit. When changing to a finer grit, move across the sanding lines that were made by a previous coarser disc. SANDING METAL When sanding automobiles or appliances, wipe the metal clean with a non-flammable solvent or commercial cleaner to remove all wax and grease. By doing this first, the sanding discs will sand better and last longer. For heavy duty work, use a coarse grit disc first. Follow-up with a medium grit to remove scratches. To produce smooth finish, use fine grit disc.

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. !WARNING To avoid accidents always disconnect the tool from the power supply before cleaning or performing any maintenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air. Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attemp...
