[. . . ] These cords are rated for outdoor use and reduce the risk of electric shock. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Use clamps or other practical way 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. [. . . ] Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. When using depressed center grinding wheels, be sure to use only fiberglassreinforced wheels. Run the tool (with guard) at no load for about a minute, holding tool away from others. Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury. If control of tool is lost, cord may become wrapped around you and cause personal injury. Make sure the wheel is not contacting the workpiece before the switch is turned on. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel. Hold the tool so that sparks fly away from you and other persons or flammable materials. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. ALWAYS wear proper apparel including long sleeve shirts, leather gloves and shop aprons to protect skin from contact with hot grindings. Use of this tool to grind or sand some products, paints and wood could expose user to dust containing hazardous substances. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Press the shaft lock to prevent spindle rotation when installing or removing accessories. CAUTION: Before plugging in the tool, always check to see that the slide switch actuates properly and returns to the "OFF" position when the rear of the slide switch is depressed. Switch can be locked in "ON" position for ease of operator comfort during extended use. For continuous operation, press the front of the slide switch to lock it. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. CAUTION: Always be sure that the side grip is installed securely before operation. CAUTION: When using a depressed center grinding wheel/Multidisc, flex wheel, wire wheel brush or cut-off wheel, the wheel guard must be fitted on the tool so that the closed side of the guard always points toward the operator. Mount the wheel guard with the protrusion on the wheel guard band aligned with the notch on the bearing box. [. . . ] Lock nut Abrasive cut-off wheel Inner flange Wheel guard for cut-off wheel During cutting operations, never change the angle of the wheel. Placing side pressure on the cut-off wheel (as in grinding) will cause the wheel to crack and break, causing serious personal injury. CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance. Regularly clean the tool's air vents or whenever the vents start to become obstructed. [. . . ]
