[. . . ] 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 1. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Unmodified plugs and matching outlets will reduce risk of electric shock. [. . . ] Do not damage the spindle, the flange (especially the installing surface) or the lock nut. For tools intended to be fitted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length. Before using the tool on an actual workpiece, test run the tool at the highest no load speed for at least 30 seconds in a safe position. Stop immediately if there is any vibration or wobbling that could indicate poor installation or a poorly balanced wheel. Make sure 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. Pay attention that the wheel continues to rotate after the tool is switched off. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. 2. When use cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation. Cutting discs must not be subjected to any lateral pressure. 2. 3. Always stop tool operation and charge the battery cartridge when you notice less tool power. Charge the battery cartridge with room temperature at 10°C - 40°C (50°F - 104°F). Let a hot battery cartridge cool down before charging it. SAVE THESE INSTRUCTIONS. ENC007-2 IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY CARTRIDGE 1.
