User manual MAKITA HR2470F

[. . . ] 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. A moment of inattention while operating power tools may result in serious personal injury. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. [. . . ] DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to rotary hammer safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury. Volts amperes hertz alternating current no load speed Class II Construction revolutions or reciprocation per minute number of blow CAUTION: Do not look in the light or see the source of light directly. Be careful not to scratch the lens of lamp, or it may lower the illumination. CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on 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. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the switch trigger fully, then release it. 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. For model HR2470T/HR2470FT The quick change chuck for SDS-plus can be easily exchanged for the quick change drill chuck. CAUTION: Before removing the quick change chuck for SDS-plus, always remove the bit. Grasp the change cover of the quick change chuck for SDS-plus and turn in the direction of the arrow until the change cover line moves from the symbol to the symbol. For drilling in wood, metal or plastic materials, depress the lock button and rotate the action mode changing knob to the symbol. CAUTION: Do not rotate the action mode changing knob when the tool is running under load. To avoid rapid wear on the mode change mechanism, be sure that the action mode changing knob is always positively located in one of the three action mode positions. Grasp the change cover of the quick change drill chuck and set the line to the symbol. Grasp the change cover of the quick change drill chuck and turn the change cover line to the symbol until a click can clearly be heard. Action mode changing knob 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. Bits such as hole saw, which tend to pintch or catch easily in the hole, are not appropriate for this tool. This is because they will cause the torque limiter to actuate too frequently. [. . . ] 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 twisting force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece. A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out.
