User manual MAKITA HR3550C

[. . . ] Safety hints For your own safety, please refer to enclosed the safety instructions. Hold 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. [. . . ] 6 & 9) For drilling in wood, metal or plastic materials, rotate the shift lever so that the symbol is aligned with the pointer on the change lever. cAUTION: · Do not rotate the change lever and/or the shift lever when the tool is running under load. To avoid rapid wear on the mode change mechanism, be sure that the change lever and/or the shift lever is always positively located in one of the three action mode positions. The action mode cannot be changed directly from ``hammering only'' to ``rotation only'' or from ``rotation only'' to ``hammering only''. First set the change lever and the shift lever to ``rotation with hammering'' mode position shown in Fig. Then set them to the position for ``hammering only'' or ``rotation only''. CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the ``OFF'' position when released. The revolutions and blows per minute can be adjusted just by turning the adjusting dial. Refer to the table below for the relationship between the number settings on the adjusting dial and the revolutions/blows per minute. CAUTION: When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reaction. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. 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. Never use ``rotation with hammering'' when the drill chuck assembly is installed on the tool. NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing. The torque limiter will actuate when a certain torque level is reached. CAUTION: As soon as the torque limiter actuates, switch off the tool immediately. The green power-ON indicator lamp lights up when the tool is switched ON. If the indicator lamp is lit but the tool does not start, the carbon brushes may be worn out, or the electric circuit or the motor may be defective. [. . . ] Be careful not to damage the terminals or lead wires especially when wiping out the old grease or installing the handle. To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Center. Driftfunktionsläget kan inte ändras direkt från ``endast slag'' till ``endast rotation'', eller från ``endast rotation'' till ``endast slag''. CAUTION: These accessories or attachments are recommended for use with your Makita tool specified in this manual. [. . . ]
