[. . . ] Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. unmodified plugs and matching outlets will reduce risk of electric shock. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and This enables better control of the power tool in unexpected situations. [. . . ] Have your power tool serviced by a qualified repair person using only identical replacement parts. DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to drill safety rules. If you use this power 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. Do not touch the drill bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin. Ensure the switch is in the off position before inserting battery pack. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. Always stop tool operation and charge the battery cartridge when you notice less tool power. 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. When not operating the tool, always set the reversing switch lever to the neutral position. Place the chuck key in each Be sure to tighten all three chuck holes evenly. To remove the bit, turn the chuck key counterclockwise in just one hole, then loosen the chuck by hand. Drilling in wood When drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece. Drilling in metal To prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. cAUTION: Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. There is a tremendous force exerted on the tool/bit at the time of hole break through.
