Makita HR2475 Owners Manual - Page 8

CAUTION: • Never use "rotation with hammering" when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged. Also, the drill chuck will come off when reversing the tool. • 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 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. However, the tool may back out abruptly if you do not hold it firmly. • Always secure small workpieces in a vise or similar hold-down device. • When performing diamond core drilling operations, always set the change lever to the position to use "rotation only" action. If performing diamond core drilling operations using "rotation with hammering" action, the diamond core bit may be damaged.
