. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 4.
Tool Use and Care 1. Use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. 2. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. 3. Do not use the power tool if the Power Switch does not turn it on or off.
3. Maintain a safe working environment. Keep the work area well lit. Make sure there is adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris. Do not use a power tool in areas near flammable chemicals, dusts, and vapors. Do not use this product in a damp or wet location. 4. Avoid unintentional starting. Make sure you are prepared to begin work before turning on the Belt Sander. 5. Do not force the Belt Sander.
GROUNDING WARNING! Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use.
2. Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See Figure B.) Extension Cords 1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.
