Fastening time (second) 2. Fastening torqueHold the tool firmly and place the point of the driver bitin the screw head. Apply forward pressure to the tool tothe extent that the bit will not slip off the screw and turnthe tool on to start operation.NOTICE: If you use a spare battery to continuethe operation, rest the tool at least 15 min.NOTE: Use the proper bit for the head of the screw/bolt that you wish to use.NOTE: When fastening M8 or smaller screw, choosea proper impact force and carefully adjust pressure onthe switch trigger so that the screw is not damaged.NOTE: Hold the tool pointed straight at the screw.NOTE: If the impact force is too strong or you tightenthe screw for a time longer than shown in the figures,the screw or the point of the driver bit may be over-stressed, stripped, damaged, etc. Before starting yourjob, always perform a test operation to determine theproper fastening time for your screw.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 the classof bolt are the same, the proper fastening torquewill differ according to the diameter of bolt.• Even though the diameters of bolts are the same, theproper fastening torque will differ according to thetorque coefficient, the class of bolt and the bolt length.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.MAINTENANCECAUTION: Always be sure that the tool isswitched off and the battery cartridge is removedbefore attempting to perform inspection ormaintenance.NOTICE: Never use gasoline, benzine, thinner,alcohol or the like. Discoloration, deformation orcracks may result.To maintain product SAFETY and RELIABILITY,repairs, any other maintenance or adjustment shouldbe performed by Makita Authorized or Factory ServiceCenters, always using Makita replacement parts.OPTIONALACCESSORIESCAUTION: These accessories or attachmentsare recommended for use with your Makita toolspecified in this manual.
