[. . . ] b) 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. 5 b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. [. . . ] Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. This enables better control of the power tool in unexpected situations. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The correct power tool will do the job better and safer at the rate for which it was designed. b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. c) 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. d) 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.
