8extent that the bit will not slip off the screw and turn thetool on to start operation.NOTE:• Use the proper bit for the head of the screw/boltthat you wish to use.• When fastening screw M8 or smaller, choose aproper hammer force and carefully adjust pressureon the switch trigger so that the screw is notdamaged.• Hold the tool pointed straight at the screw.• If the hammering force is too strong you tighten thescrew for a time longer than shown in the figures,the screw or the point of the driver bit may beoverstressed, stripped, damaged, etc. Beforestarting your job, always perform a test operationto determine the proper fastening time for yourscrew.The fastening torque is affected by a wide variety offactors including the following. After fastening, alwayscheck the 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 socketbit will cause a reduction in the fastening torque.3. Bolt• Even though the torque coefficient and theclass of bolt are the same, the proper fasteningtorque will differ according to the diameter ofbolt.• Even though the diameters of bolts are thesame, the proper fastening torque will differaccording to the torque coefficient, the class ofbolt and the bolt length.4. The manner of holding the tool or the material ofdriving position to be fastened will affect thetorque.5. Operating the tool at low speed will cause areduction in the fastening torque.MAINTENANCECAUTION:• Always be sure that the tool is switched off and thebattery cartridge is removed before attempting toperform inspection or maintenance except for thefollowing troubleshooting related to the light.CleaningFrom time to time wipe off the outside (tool body) of thetool using a cloth dampened in soapy water.CAUTION:• Never use gasoline, benzine, thinner, alcohol or thelike. Discoloration, deformation or cracks mayresult.TroubleshootingTrouble Light status/LED indicator status/tool status Steps to be takenThe tool stopsduring operation.LED indicator for empty signal forremaining battery capacity lights up.Light flickers once per second.Light flickers five times per second.Switch trigger has been pulledcontinuously for more than 130 seconds.Other SymptomsWhen the status is still unchanged, stopusing and have the tool repaired by aMakita local service center.Cool down it fully. The tool restarts after itstemperature becomes low.Remaining battery capacity level is low.Charge the battery cartridge.When the LED indicator still lights upeven after charging the battery cartridge,the tool temperature is high.The tool temperature is high. Cool downit fully. The tool restarts after its temperaturebecomes low.If the motor still remains locked, stop usingand have the tool repaired by a Makitalocal service center.(When the tool has stopped due to themotor locking, withdraw the batterycartridge one time and then insert it againor release the switch trigger for more than60 seconds to restart the tool.)Use the tool with the motor not locked.Release the switch trigger.Stop using and have the tool repaired bya Makita local service center.011187
