A wrench or a key left attached to   a rotating part of the power tool may result in personal   injury.    Do not overreach. keep proper footing and balance   at all times. This enables better control of the power tool   in unexpected situations.    Dress properly. Do not wear loose clothing or jewelry.   keep your hair, clothing and gloves away from moving   parts. Loose clothes, jewelry, or long hair can be caught   in moving parts.    If devices are provided for the connection of dust   extraction and collection facilities, ensure these are   connected and properly used. Use of these devices can   reduce dust-related hazards.   WARNING:   Read all instructions Failure to follow all   instructions listed below may result in electric   shock, fire and/or serious injury. The term “power   tool” in all of the warnings listed below refers   to your mains-operated (corded) power tool or   battery-operated (cordless) power tool.   SAVE THESE INSTRUCTIONS   WORk AREA SAFETY    keep work area clean and well lit. Cluttered or dark   areas invite accidents.    Do not operate power tools in explosive   atmospheres, such as in the presence of flammable   liquids, gases or dust. Power tools create sparks which   may ignite the dust or fumes.    Do not wear loose clothing or jewelry. Contain long   hair. Loose clothes, jewelry, or long hair can be drawn   into air vents.    Do not use on a ladder or unstable support. Stable   footing on a solid surface enables better control of the   tool in unexpected situations.    keep children and bystanders away while operating a   power tool. Distractions can cause you to lose control.   ELECTRICAL SAFETY   POWER TOOL USE AND CARE    Power tool plugs must match the outlet. Never modify   the plug in any way. Do not use any adapter plugs with   earthed (grounded) power tools. Unmodified plugs and   matching outlets will reduce risk of electric shock.    Do not force the power tool. Use the correct power   tool for your application. The correct power tool will   do the job better and safer at the rate for which it was   designed.    Avoid body contact with earthed or grounded surfaces   such as pipes, radiators, ranges and refrigerators.   There is an increased risk of electric shock if your body   is earthed or grounded.    Do not expose power tools to rain or wet conditions.   Water entering a power tool will increase the risk of   electric shock.    Do not use the power tool if the switch does not turn   it on and off. Any power tool that cannot be controlled   with the switch is dangerous and must be repaired.    Disconnect the plug from the power source and/or   the battery pack from the power tool before making   any adjustments, changing accessories, or storing   power tools. Such preventive safety measures reduce   the risk of starting the power tool accidentally.    Store idle power tools out of the reach of children and   do not allow persons unfamiliar with the power tool   or these instructions to operate the power tool. Power   tools are dangerous in the hands of untrained users.    Maintain power tools. Check for misalignment or   binding of moving parts, breakage of parts and any   other condition that may affect the power tool’s   operation. If damaged, have the power tool repaired   before use. Many accidents are caused by poorly   maintained power tools.    Do not abuse the cord. Never use the cord for carrying,   pulling or unplugging the power tool. keep cord away   from heat, oil, sharp edges or moving parts. Damaged   or entangled cords increase the risk of electric shock.    When operating a power tool outdoors, use an   extension cord suitable for outdoor use. Use of a   cord suitable for outdoor use reduces the risk of electric   shock.   PERSONAL SAFETY    Stay alert, watch what you are doing and use   common sense when operating a power tool. Do   not use a power tool while you are tired or under the   influence of drugs, alcohol or medication. A moment   of inattention while operating power tools may result in   serious personal injury.    Use safety equipment. Always wear eye protection.   Safety equipment such as dust mask, non-skid safety   shoes, hard hat, or hearing protection used for appropriate   conditions will reduce personal injuries.    keep cutting tools sharp and clean. Properly maintained   cutting tools with sharp cutting edges are less likely to   bind and are easier to control.    Use the power tool, accessories and tool bits etc., in   accordance with these instructions and in the manner   intended for the particular type of power tool, taking   into account the working conditions and the work   to be performed. Use of the power tool for operations   different from those intended could result in a hazardous   situation.    Avoid accidental starting. Ensure the switch is in the   off-position before plugging in. Carrying power tools   with your finger on the switch or plugging in power tools   that have the switch on invites accidents.   3 Download from Www.Somanuals.com.

All exposed metal parts are isolated   from the internal metal motor components with protecting   insulation. Double insulated tools do not need to be   grounded.   When using a power tool at a considerable distance from   a power source, be sure to use an extension cord that has   the capacity to handle the current the tool will draw. An   undersized cord will cause a drop in line voltage, resulting in   overheating and loss of power. Use the chart to determine   the minimum wire size required in an extension cord. Only   round jacketed cords listed by Underwriter’s Laboratories   (UL) should be used.   WARNING:   When working outdoors with a tool, use an extension   cord that is designed for outside use. This type of cord is   designated with “WA” on the cord’s jacket.   The double insulated system is intended to protect   the user from shock resulting from a break in the   tool’s internal wiring. Observe all normal safety   precautions to avoid electrical shock.   Before using any extension cord, inspect it for loose or   exposed wires and cut or worn insulation.   NOTE: 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   authorized service center for repair. Always use original   factory replacement parts when servicing.   **Ampere rating (on tool data plate)   0-ꢀ.0   ꢀ.1-3.4 3.5-5.0 5.1-7.0 7.1-1ꢀ.0 1ꢀ.1-16.0   Cord Length   Wire Size (A.W.G.)   ꢀ5'   50'   16   16   16   16   16   16   16   16   14   16   14   1ꢀ   14   14   10   14   1ꢀ   — ELECTRICAL CONNECTION   100'   This product has a precision-built electric motor.

Remember that a careless fraction of a   second is sufficient to inflict serious injury.    Sanding wood, metals, and plastics    Smoothing rough boards, chamfering, rounding edges    Removing rust, paint, varnishes, and stains   WARNING:   WARNING:   If your sanding job becomes dusty or if you have a   breathing condition, wear a dust mask or respirator   to prevent damage to your health.   Always wear safety goggles or safety glasses with   side shields when operating power tools. Failure   to do so could result in objects being thrown into   your eyes resulting in possible serious injury.   SELECTING SANDING BELTS   Selecting the correct size and type of sanding belt is an   important step in achieving a high quality sanded finish. Alu-   minum oxide, silicon carbide, and other synthetic abrasives   are best for power sanding.   WARNING:   Do not use any attachments or accessories   not recommended by the manufacturer of this   product. The use of attachments or accessories   not recommended can result in serious personal   injury.   In general, when sanding, coarse grit removes the most ma-   terial and fine grit produces the best finish. The condition of   the surface to be sanded determines which grit will do the   best job. If the surface is rough, start with a coarse grit and   sand until the surface is uniform. Then use medium grit to   remove scratches left by the coarser grit. Finally, use finer   grit for finishing the surface. Always continue sanding with   each grit until the surface is uniform.   WARNING:   Before connecting the sander to a power supply,   make sure it is not in the locked-on position. Failure   to do so could result in accidental starting of the   tool resulting in serious injury.   SETTING THE BELT SANDER SPEED   Refer to the chart below for belt sander speed selections.   SPEED   BELT GRIT   MATERIAL   A B C D E F 40   60   80   100   150   240   UNDRESSED   LUMBER         SOFTWOOD   CHIPBOARD                LUMBER        RUST REMOVAL   PAINTED SURFACE                  NON-FERROUS   METAL       10   Download from Www.Somanuals.com.
