7NOTE:• The depth gauge cannot be used at the positionwhere the depth gauge strikes against the tool body.OPERATIONHammer drilling operationCAUTION:• There is a tremendous and sudden twisting forceexerted 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 theconcrete. Always use the side grip (auxiliary handle) andfirmly hold the tool by both side grip and switch handleduring operations. Failure to do so may result in the lossof control of the tool and potentially severe injury.When drilling in concrete, granite, tile, etc., move theaction mode changing lever to the position of symbolto use "rotation with hammering" action.Be sure to use a tungsten-carbide tipped bit.Position the bit at the desired location for the hole, thenpull the switch trigger. Do not force the tool. Lightpressure gives best results. Keep the tool in positionand prevent it from slipping away from the hole.Do not apply more pressure when the hole becomesclogged with chips or particles. Instead, run the tool atan idle, then remove the bit partially from the hole. Byrepeating this several times, the hole will be cleaned outand normal drilling may be resumed.Blow-out bulb (optional accessory)1001302After drilling the hole, use the blow-out bulb to clean thedust out of the hole.Drilling operationCAUTION:• Pressing excessively on the tool will not speed up thedrilling. In fact, this excessive pressure will only serveto damage the tip of your bit, decrease the toolperformance and shorten the service life of the tool.• There is a tremendous force exerted on the tool/bitat the time of hole break through. Hold the toolfirmly and exert care when the bit begins to breakthrough the workpiece.• A stuck bit can be removed simply by setting thereversing switch to reverse rotation in order toback out. However, the tool may back out abruptlyif you do not hold it firmly.• Always secure small workpieces in a vise orsimilar hold-down device.When drilling in wood, metal or plastic materials, turnthe action mode changing lever to the positionof symbol to use "rotation only" action.Drilling in woodWhen drilling in wood, the best results are obtained withwood drills equipped with a guide screw. The guidescrew makes drilling easier by pulling the bit into theworkpiece.Drilling in metalTo prevent the bit from slipping when starting a hole,make an indentation with a center-punch and hammerat the point to be drilled. Place the point of the bit in theindentation and start drilling.Use a cutting lubricant when drilling metals. Theexceptions are iron and brass which should be drilleddry.MAINTENANCECAUTION:• Always be sure that the tool is switched off andunplugged before attempting to perform inspectionor maintenance.• Never use gasoline, benzine, thinner, alcohol orthe like. Discoloration, deformation or cracks mayresult.Cleaning vent holes1002697The tool and its air vents have to be kept clean.Regularly clean the tool's air vents or whenever thevents start to become obstructed.To maintain product SAFETY and RELIABILITY, repairs,carbon brush inspection and replacement, any othermaintenance or adjustment should be performed byMakita Authorized Service Centers, always using Makitareplacement parts.1.
