The hook is convenient for temporarily hanging the tool.This can be installed on either side of the tool. To installthe hook, insert it into a groove in the tool housing oneither side and then secure it with a screw. To remove,loosen the screw and then take it out.OPERATIONThe 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.12010080604020M14(9/16")M12(1/2")M10(3/8")M8(5/16")Standard boltN•mFastening torqueFastening time (S)Proper fastening torque(ft•lbs)(87)(72)(58)(43)(29)(14)0140(101)1.0 2.0 3.0M16(5/8")M16(5/8")M14(9/16")M12(1/2")M10(3/8")M8(6/16")High tensile boltFastening torqueFastening time (S)Proper fastening torqueN•m(ft•lbs)0 1.0 2.0 3.0M12(1/2")M10(3/8")160(116)140(101)120(87)100(72)80(58)60(43)40(29)20(14)M8(5/16")M12(1/2")M10(3/8")M8(5/16")Hold 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 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 theclass of bolt are the same, the proper fasten-ing torque will differ according to the diame-ter of bolt.•Even though the diameters of bolts are thesame, the proper fastening torque will differaccording to the torque coefficient, the classof bolt and the bolt length.4. The manner of holding the tool or the materialof driving position to be fastened will affect thetorque.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.
