Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Power tool plugs must match the outlet. Never modify the plug in any way.
Stay alert, watch what you are doing and use common sense when operating a power tool.
Use auxiliary handle(s), if supplied with the tool. Hold power tool by insulated gripping surfaces.
Tighten the chuck by hand. Place the chuck key in each of the three holes and tighten clockwise.
Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
