Hold the sander firmly with one hand, engage trigger switch to turn the tool "ON", and note the tracking of the sanding belt. If the belt runs outward (towards the open side of the sander) turn tracking adjustment knob counter-clockwise. If the belt runs inward, turn the knob clockwise. Adjust the belt in this manner until the edge of the belt runs flush with the outer edge of both pulleys and covers the platen protector. Your sander is now ready for use. In some cases, the belt will require a slight readjustment after it is applied to the work surface, so note the tracking carefully during the first minutes of operation and readjust as required. TRACKING ADJUSTMENT KNOB ADJUSTABLE TOP HANDLE The top handle provided should always be used to guide and balance the tool. Grip the tool by the multi-position top handle, and the rear handle, for safe control and ease of operation. To adjust the top handle, loosen wing knob at least two full turns, position handle and retighten knob firmly. DUST EXTRACTION Proper dust removal will extend abrasive life and produce more consistent results. The integral dust extraction system collects sanding dust in the dust bag assembly. Bag should be emptied when it is no more than half full, and should be replaced when the surface becomes clogged with dust or efficiency will be reduced. To empty or replace bag, pull the bag free of dust port. Open the zipper on the rear of the bag, and empty contents into suitable receptacle. To install bag, firmly push the bag into place on the dust port so that it covers the "O" ring to create a seal and the metal flange on dust bag makes contact with the static clip as shown. The static clip is provided to dissipate static electricity that accumulates in the bag and can cause annoying shock to the user. For added efficiency, a vacuum hose and adaptor (optional accessories) are also available which will allow your sander to be connected to a shop vacuum system. See your Bosch catalog for optional Bosch Airsweep accessories. METAL FLANGE DUST BAG STATIC CLIP Sanding Tips SELECTING THE SANDING BELT It is very important that you select the proper belt for each particular application. To do this you should understand the method of marking or coding on the back of most belts. "CLOSED COAT" means the surface is densely covered with as much grit as the adhesive will hold. "OPEN COAT" means the grit has been applied evenly, but openly to the surface. An "open coat" will not clog or fill as readily as "closed coat". In general, aluminum oxide abrasive belts are best for woodworking because they are tougher and last longer. Sanding belts should be stored in a cool, dry place. Do not store near heat or near a window where the sun can reach them. TECHNIQUE Grasp the handles firmly. Start the sander with the belt off the work (NOTE: never start or stop -8-
