Avoid using solvents when cleaning plastic pads. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc. ,_ 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. 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 grindings frem these materials are highly abrasive to electric tool pads, such as bearings, brushes, commutators, etc. Consequently, it is not recommended that this toot be used for extended work on any fiberglass material, wallboard, spackling compounds, or piaster. During any use on these materials, it is extremely important that the tool is cleaned frequently by blowing with an air jet. LUBRICATION 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. ,_ 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. DOUBLEINSULATION Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. IMPORTANT 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 Service Center for repair. Always use original factory replacement parts when servicing. 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. A wire gage size (A.W.G.) of at least 16 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. ,_IL CAUTION: Keep extension cords away from the drilling area and position the cord so that it will not get caught on lumber, tools, etc., during drilling operation. _ll WARNING: Check extension cords before each use. If damaged replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury. Extension cords suitable for use with your drill are available at your nearest Sears Retail Store. 12 ThefollowingrecommendedaccessoriesarecurrentlyavailableatSearsretailstores. • HighSpeedBits(Forwoodor metal).........1/2in.Max. • DowelingJig (ItemNo.9-4186) Bits............................................... • Masonry3/4in.Max. • Drill Stand (Item No. _-25989) • WoodBoringBits...........................................• Wire Brushes, All 1in.Max. • HoleSaws..................................................... 2 in.Max.
