User manual MAKITA HR3540C

[. . . ] 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. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. The speed adjusting dial can be turned only as far as 5 and back to 1. [. . . ] Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. If the tool is operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction. Always use the side grip to ensure operating safety when drilling in concrete, masonry, etc. The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. 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. 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. 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. 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. ⷠAlways secure small workpieces in a vise or similar hold-down device. Then make sure that the bit is securely held in place by turning it slightly. nOTE: · The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Keep the tool in position and prevent it from slipping away from the hole. [. . . ] Never remove it forcibly without aligning the change lever with the symbol . Wipe out the old grease inside and replace with a fresh grease (30 g). cAUTION: · Be careful not to damage the connector or lead wires especially when wiping out the old grease. Be careful not to damage the connector or lead wires especially when installing the handle. [. . . ]
