6Hold the ring and turn the sleeve counterclockwise toopen the chuck jaws. Place the bit in the chuck as far asit will go. Hold the ring firmly and turn the sleeve clock-wise to tighten the chuck.To remove the bit, hold the ring and turn the sleeve coun-terclockwise.For 6041DTo install the bit, place it in the chuck as far as it will go.Tighten the chuck by hand. Place the chuck key in eachof the three holes and tighten clockwise. Be sure totighten all three chuck holes evenly.To remove the bit, turn the chuck key counterclockwise injust one hole, then loosen the chuck by hand.OPERATIONScrewdriving operationPlace the point of the driver bit in the screw head andapply pressure to the tool. Start the tool slowly and thenincrease the speed gradually. Release the trigger just asthe screw bottoms out. If the trigger is not released, thescrew may strip out the hole or the screw and/or bit maybe damaged.CAUTION:• Make sure that the driver bit is inserted straight inthe screw head, or the screw and/or bit may bedamaged.NOTE:• When driving wood screws, predrill pilot holes tomake driving easier and to prevent splitting of theworkpiece. See the chart.Drilling operationDrilling 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 hammer atthe point to be drilled. Place the point of the bit in theindentation and start drilling.Use a cutting lubricant when drilling metals. The excep-tions are iron and brass which should be drilled dry.CAUTION:• Pressing excessively on the tool will not speed upthe drilling. In fact, this excessive pressure will onlyserve to damage the tip of your bit, decrease thetool performance and shorten the service life of thetool.• 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 to backout. However, the tool may back out abruptly if youdo not hold it firmly.• Always secure small workpieces in a vise or similarhold-down device.MAINTENANCECAUTION:• Always be sure that the tool is switched off beforeattempting to perform inspection or maintenance.To maintain product SAFETY and RELIABILITY, repairs,any other maintenance or adjustment should be per-formed by Makita Authorized or Factory Service Centers,always using Makita replacement parts.DISPOSING OF TOOLA Ni-Cd battery is built into the handle of the tool. Alwaysremove it before disposing of the tool.1.
