BSC 41 _ 3 SEARS TOWER CHICAGO, 1L 60684 gNTRODUCTION DOUBLE INSULATION is a concept in safety, in etectric power tools, which eliminates the need for the usual three wire grounded power cord and grounded supply system. Wherever there is electric current in the tool there are two complete sets of insulation to protect the user_ All exposed metal parts are isolated from the internal metal motor components with protecting insulation.. IMPORl'ANT_Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician.. For service we suggest you return the tool to your nearest Sears Store for repair. Always use original factory replacement parts when servicing. RULES FOR SAFE OPERATION Your Craftsman 4-inch Dustless Belt Sander is suitable for coarse, medium and fine sanding of wood, metals, plastics and other materials. It is ideal when used for smoothing rough boards, chamfering, rounding edges and many other general sanding applications. It is ideal for refinishing large pieces of furniture, stairs and other large surfaces. Its balanced design makes it easy to use. The built-in dust collection system will remove most of the sanding dust from the work and eliminate the dust in the air -- usually associated with power sanding° SWITCH A trigger switch controls operation of the Sander', The trigger switch can be locked on for continuous operatiom To lock, pull trigger, press lock button inward, and release trigger, Pull trigger and release to stop° 1. KNOW YOUR POWER TOOL _ Read owner's manual carefulty,_ Learn its applications and limitations as well as the specific potential hazards peculiar to this tool. 2, GROUND ALL TOOLS -- UNLESS DOUBLE-INSULATED. If tool is equipped with three-prong plug, it should be plugged into a three-hole electrical receptacle, tf adapter is used to accommodate two-prong receptacle, the adapter wire must be attached to a known ground. (Usually the screw securing receptacle cover plate)_ Never remove third prong. 3. KEEP GUARDS IN PLACE and in working order. 4 KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents. 5.

USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavy duty toot.. 10 WEAR PROPER APPAREL. No loose clothing or jewetry to get caught in moving parts_ Rubber gloves and footwear are recommended when working outdoors, 11 USE SAFETY GLASSES with most tools. Also face or dust mask if cutting operation is dusty_ 12 DON'T ABUSE CORD. Never carry toot by cord or yank it to disconnect from receptacle. Keep cord from heat, oil and sharp edges° !3. SECURE WORK. Use clamps or a vise to hold work it's safer than using your hand and it frees both hands to operate tool 14 DON'T OVERREACH.

Don't carry plugged-in tools with finger on switch Be sure switch is off when plugging in. 19 OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords suitable for use outdoors and so marked Page 2 OPERATION PREPARING FOR OPERATION Your Sander is equipped with its own built-in auxiliary handle located at the front of the unit, This handle allows for twohand use which wilt aid in maintaining complete control and keeping sanding area level with work piece (See Fig, 1), Selecting the correct size and type sanding belt is an extremely important step in achieving a high quality sanded finish,. Aluminum oxide silicone carbide and other synthetic abrasives are best for power sanding. In general, coarse grit will remove the most material and finer grit will produce best 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 finer grit belt used for finishing of the surface. Always continue sanding with each grit belt until surface is uniform° ,\ Fig, I Fig, 2 INSTALLING AND ADJUSTING SANDING BELT Be sure power cord is disconnected from power supply. 1. Release tension on belt by pushing the front pulley squarely against the top or edge of workbench (See Fig. 2). When the pulley is pushed back it will lock in that position, allowing slack in the belt so it can be removed. NOTE: Idler pulley rubbing housing when in the released position, without sandpaper, does not damage toot operation. The sanding belt, when assembled, will not allow pulley to project as far. 2, To install new belt, place belt over both pulleys, making sure that arrow on inside of belt is pointing in the direction of rotation which is clockwise when looking into open side of sander. 3,. Make sure fingers are not in a position to get mashed. Pull hard on lever (A) until pulley is released and tension is applied to bett. The lever will move freely at first and then become harder to pull 4,, To adjust belt, connect sander to power supply,, Stand sander on end as illustrated (See Fig,, 3), Pull switch trigger and release immediately while observing tracking of belt. 5o tf belt runs outward, turn tracking screw (B) clockwise and counterclockwise if belt runs inward. This should be done until you are sure belt will not come in contact with rub strip, 6 Start sander and fine adjust the tracking screw (B) until belt stabilizes. When correctly adjusted, the outer edge of the belt will be even with outer edge of wear plate, Note: Belt life will be increased if a few seconds are spent adjusting the belt tracking properly° TO OPERATE Clamp or otherwise secure the work to prevent it moving under the Sander., With Sander off work, press the trigger switch and when the motor reaches its maximum speed, lower the Sander on the work with a slight forward motion Using the main handle to control the Sander and the front handle only to guide it, move it slowly over the work, Allowing the Sander to remain in one place will result in an uneven surface, The Sander was designed to provide the proper weight on the sand belt and extra pressure wil! only result in uneven work, stow cutting from slow belt speed, clogged belts and possible motor burnouL Use the proper belt when heavy cutting is desired, not heavy pressure. The importance of this cannot be over-emphasized, the weight has been built into the tool to give the most efficient pressure at the proper location. Poge 3 MAgNTENANCE WHEN SERVICING USE ONLY IDENTICAL BRUSH PARTS. REPLACEMENT Disconnect 1 REPLACEMENT sander trom power supply. Remove brush caps (A) with screwdriver. See Fig 4 2.

The operation of any Power Tool can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields before commencing power tool operation° We recommend Wide Vision Safety Mask for use over spectacles or standard safety glasses, available at Sears Retail or Catalog Stores, Page 4 GENERAL DUST PICK-UP The dust bag assembly is slipped with a twisting motion over the blower exhaust.. The bag may be turned toward the side as required for the operator's convenience Although the bag is of ample size it should be emptied frequently to maintain the pick-up efficiency. The bag is emptied by grasping the fitting and twisting it off the blower exhaust. Opening the zipper at the bottom of the bag will allow complete cleaning.. When sanding, some dust, paper, belt threads and etc. may collect on the blower and reduce the efficiency of the blower.. To clean blower (See Fig. 5) remove screws (A) and blower housing coupling (B)_. Replace blower housing coupling (B) and screws (A).. Do not over tighten screws (A)o All 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 Only the parts shown outside Section A on page six are intended to be replaced by the customer,. Parts listed in Section A represent an important part of the double insulation system and should be serviced only by a qualified service technician° Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc. When electric tools are used on fiberglass boats, sports cars, etc., it has been found that they are subject to accelerated wear and possible premature failure, as the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutator,etc. Consequently it is not recommended that this tool be used for continuous production work on any fiberglass material. During any use on fiberglass it is extremely important that the tool is cleaned frequently by blowing with an air jet° CORDS The use of any extension cord wil! cause some loss of power° To keep the toss to a minimum and to prevent tool overheating, follow the recommended cord sizes on the chart at right.
