[. . . ] Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. 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. Grasp the change cover of the quick change drill chuck and set the line to the symbol. [. . . ] ⷠBits such as hole saw, which tend to pinch 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. ⷠ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. Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. For Model HR2470T/HR2470FT The quick change chuck for SDS-plus can be easily exchanged for the quick change drill chuck. Install the side grip so that the teeth on the grip fit in between the protrusions on the tool barrel. Coat the bit shank head beforehand with a small amount of bit grease (about 0. 11) After installing, always make sure that the bit is securely held in place by trying to pull it out. To remove the bit, pull the chuck cover down all the way and pull the bit out. There is tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Eccentricity in the bit rotation may occur while operating the tool with no load. Then make sure that the bit is securely held in place by turning it slightly. After drilling the hole, use the blow-out bulb to clean the dust out of the hole. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing. When installing it, refer to "changing the quick change chuck for SDS-plus" described on the previous page. Never use "rotation with hammering" when the quick change drill chuck is installed on the tool. 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. 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. [. . . ] ⷠThe declared vibration emission value may also be used in a preliminary assessment of exposure. wARNING: · The vibration emission during actual use of the power tool can differ from the declared emission value depending on the ways in which the tool is used. ⷠBe sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time). These accessories or attachments are recommended for use with your Makita tool specified in this manual. [. . . ]
