[. . . ] Do not operate power tools in explosive 2 Power tools create sparks which may ignite the dust or fumes. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. Never use the cord for carrying, pulling or unplugging the power tool. [. . . ] The correct power tool will do the job better and safer at the rate for which it was designed. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. In accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. Have your power tool serviced by a qualified repair person using only identical replacement parts. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to hammer 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. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. [. . . ] Extension cord CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance. To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts. When connecting the power supply cord to an extension cord, use the hook so that the plug of power supply cord cannot be disconnected from the connector of extension cord. CAUTION: These accessories or attachments are recommended for use with your Makita tool specified in this manual. [. . . ]
