FLUSH SANDING

Your sander has been designed to allow convenient flush sanding on the right side of the sander.

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.
