9NOTE:• When the LED display goes off, the tool is turned off tosave the battery power. To check the remaining batterycapacity, slightly pull the switch trigger.• The LED display goes off approximately one minuteafter releasing the switch trigger.• When the temperature of the tool gets high, the lightflashes once per second for one minute, and then theLED display goes off. In this case, cool down the toolbefore operation.ASSEMBLYCAUTION:• Always be sure that the tool is switched off and the bat-tery cartridge is removed before carrying out any workon the tool.Installing or removing driver/drill/socket bit(Fig. 11)Use only the driver/drill/socket bit shown in the figure. Donot use any other driver/drill/socket bit.For tool with shallow bit holeFor tool with deep bit hole1. To install the bit, pull the sleeve and insert the bit intothe sleeve as far as it will go. Then release thesleeve to secure the bit. (Fig. 12)2. To install the bit, insert the bit-piece and bit into thesleeve as far as it will go. The bit-piece should beinserted into the sleeve with its pointed end facingin. Then release the sleeve to secure the bit. (Fig.13)To remove the bit, pull the sleeve in the direction of thearrow and pull the bit out firmly.CAUTION:• Do not touch the drill bit shortly after operating as itgets hot. Replace the drill bit after cooling it down.NOTE:• If the bit is not inserted deep enough into the sleeve,the sleeve will not return to its original position and thebit will not be secured. In this case, try re-inserting thebit according to the instructions above.• After inserting the bit, make sure that it is firmlysecured. If it comes out, do not use it.Hook (optional accessory) (Fig. 14)CAUTION:• When installing the hook, tighten the screw firmly. Fail-ure to do so may cause the breakage of the tool or per-sonal injury.The hook is convenient for temporarily hanging the tool.This can be installed on either side of the tool.To install the hook, insert it into a groove in the tool hous-ing on either side and then secure it with a screw. Toremove, loosen the screw and then take it out.OPERATION (Fig. 15)CAUTION:• Always insert the battery cartridge all the way until itlocks in place with a little click. If you can see the redindicator on the upper side of the button, it is not lockedcompletely. Install it fully until the red indicator cannotbe seen. If not, it may accidentally fall out of the tool,causing injury to you or someone around you.• If the tool is operated continuously until the battery car-tridge has discharged, allow the tool to rest for 15 min-utes before proceeding with a fresh battery.Impact driver mode “ ”ScrewdrivingHold the tool firmly and place the point of the driver bit inthe screw head. Apply forward pressure to the tool to theextent that the bit will not slip off the screw and turn thetool on to start operation.Tightening bolts (Fig. 16 & 17)The proper fastening torque may differ depending uponthe kind or size of the screw/bolt, the material of theworkpiece to be fastened, etc. The relation between fas-tening torque and fastening time is shown in the figures.NOTE:• When the action mode is set to impact driver mode,make sure that the tool impacts properly by fastening awood screw before operation. If the tool does not workproperly, contact your nearest Makita service center.• Hold the tool pointed straight at the screw.• Use the proper bit for the head of the screw/bolt thatyou wish to use.• When fastening screw M8 or smaller, carefully adjustpressure on the switch trigger so that the screw is notdamaged.• If you tighten the screw for a time longer than shown inthe figures, the screw or the point of the driver bit maybe overstressed, stripped, damaged, etc. Before start-ing your job, always perform a test operation to deter-mine the proper fastening time for your screw.The fastening torque is affected by a wide variety of fac-tors including the following. After fastening, always checkthe torque with a torque wrench.1. When the battery cartridge is discharged almostcompletely, voltage will drop and the fasteningtorque will be reduced.2. Driver bit or socket bitFailure to use the correct size driver bit or socket bitwill cause a reduction in the fastening torque.3. Bolt• Even though the torque coefficient and the class ofbolt are the same, the proper fastening torque willdiffer according to the diameter of bolt.• Even though the diameters of bolts are the same,the proper fastening torque will differ according tothe torque coefficient, the class of bolt and the boltlength.4. The manner of holding the tool or the material ofdriving position to be fastened will affect the torque.5. Operating the tool at low speed will cause a reduc-tion in the fastening torque.A = 12 mmB = 9 mmUse only these type of bit. Follow theprocedure (1).(Note) Bit-piece is not necessary.A = 17 mmB = 14 mmTo install these types of bits, follow theprocedure (1).A = 12 mmB = 9 mmTo install these types of bits, follow theprocedure (2).(Note) Bit-piece is necessary for install-ing the bit.
