User manual MAKITA GA7910

[. . . ] When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric shock. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. [. . . ] Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut. Make sure the abrasive disc or the wheel is not contacting the workpiece before the switch is turned on. 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. Ventilate your work area adequately when you perform sanding operations. 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. When using depressed center grinding wheels, be sure to use only fiberglass-reinforced wheels. Run the tool (with guard) at no load for about a minute, holding tool away from others. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel. 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. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. Switch can be locked in "ON" position for ease of operator comfort during extended use. For continuous operation, pull the trigger and then push in the lock button. To stop the tool from the locked position, pull the trigger fully, then release it. To tighten the lock nut, press the shaft lock firmly so that the spindle cannot revolve, then use the lock nut wrench and securely tighten clockwise. 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. Fit the disc on the rubber pad and screw the lock nut onto the spindle. WARNING: Always use guard assembly or accessory kit, noted below, for type 27 depressed center grinding wheel/Multi-disc. [. . . ] Use of damaged brush could increase potential for injury from contact with broken brush wires. Mount urethane washer then thread wire cup brush onto spindle and tighten with supplied wrench. When using brush, avoid applying too much pressure which causes over bending of wires, leading to premature breakage. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. [. . . ]
