Sawdust or foreign objects being thrown into your face and eyes could result in possible serious injury. Do not connect sander to power supply before installing dust bag. SANDING TO INSTALL DUST BAG • ,_, Selecting the correct size and type of sanding belt is an important step in achieving a high quality sanded finish. Standard 4 in. x 21 in. sanding belts made of aluminum oxide, silicone carbide, and other synthetic abrasives are best for power sanding. In general, coarse grit will remove the most material and fine grit will produce the smoothest finish in all sanding operations. The condition of the surface to be sanded will determine which grit belt will do the job. If the surface is rough, start with a coarse grit belt sanding until surface is uniform. Medium grit belt may then be used to remove scratches left by the coarser belt and fine grit belt used for finishing of the surface. Always continue sanding with each grit belt until the surface is uniform. Unplug your sander. WARNING: Failure to unplug your sander could result in accidental starting causing possible serious personal injury. • Fit opening in dust bag retainer over exhaust hole on blower cover. • Slide dust bag retainer in the direction of the arrow as shown in figure 2. • BELT SELECTION Dust bag is secure when it fits snugly on blower cover.

Failure to do so could result in loss of control leading to possible serious injury. Your sander was designed to provide the proper weight on the sanding belt. Excessive pressure will result In the following: ___._..._.,,,------- Fig, Uneven work. • Clogged sanding belts. • Premature sanding belt wear. Removal rate will not increase. • Possible motor burnout. • Irregular sanding belt tracking. Note: If the sanding belt moves while sanding, you may be applying too much pressure. When this occurs remove sander from workpiece. If belt tracking is properly adjusted, sanding belt will return to its normal and correct position on the drive roller and front roller. 10 Clamp or otherwise secure the work to prevent it from moving under your sander. ,_ • Use a coarser belt when heavy sanding is desired, not heavy pressure. The importance of this cannot be overemphasized. Weight has been built into the tool to give the most efficient pressure at the proper location. WARNING: Unsecured work could be thrown back toward operator causing injury. Before placing sander on work surface, squeeze the switch trigger and let the motor reach its maximum speed, then lower your sander to the work surface with a slight forward motion. Using the rear handle to control your sander and the front handle only to guide it, move it slowly over the work. Allowing your sander to remain in one place will result in an uneven surface. Note: The front roller of your sander was not designed for contour sanding. Sanding on the front roller could cause irregularity in sanding belt tracking. 11 H _lh WARNING: When servicing, use only identical Craftsman replacement parts.

LUBRICATION Avoid using solvents when cleaning plastic pads. Most plastics are susceptible to damage from various types of commemial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc. ,_ WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required. EXTENSION CORDS The use of any extension cord will cause some loss of power. To keep the loss to a minimum and to prevent tool overheating, use an extension cord that is heavy enough to carry the current the tool will draw. WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc. come in contact with plastic pads. They contain chemicals that can damage, weaken or destroy plastic. A wire gage size (A.W.G.) of at least 14 is recommended for an extension cord 100 feet or less in length. When working outdoors, use an extension cord that is suitable for outdoor use. The cord's jacket will be marked WA, It has been found that electric tools are subject to accelerated wear and possible premature failure when they are used on fiberglass boats, sports cars, wallboard, spackling compounds, or plaster. The chips and gdndings from these materials are highly abrasive to electric tool parts such as bearings, brushes, commutators, etc. Consequently, it is not recommended that this tool be used for extended work on any fiberglass material, wallboard, spackling compounds, or plaster. During any use on these materials it is extremely important that the tool is cleaned frequently by blowing with an air jet. _1= CAUTION; Keep extension cords away from the sanding area and position the cord so that it will not get caught on lumber, tools, etc., during sanding operation. A 15 WARNING: Check extension cords before each use. If damaged replace immediately.
