[. . . ] 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. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. [. . . ] DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to recipro saw safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury. Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. Check the socket carefully for wear, cracks or damage before installation. The proper fastening torque may differ depending upon the kind or size of the bolt. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. Number of blow CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. To change the speed, first switch off the tool and then slide the speed change lever fully to the "H" side (lower side) for high speed or to the "L" side (upper side) for low speed. Before starting operation, ensure that the speed Select the speed optimum for your job. The proper fastening torque may differ depending upon the kind or size of the bolt, the material of the workpiece to be fastened, etc. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
