1 2008815NOTE:• If the bit is not inserted deep enough into the sleeve,the sleeve will not return to its original position andthe bit will not be secured. In this case, tryre-inserting the bit according to the instructionsabove.• After inserting the bit, make sure that it is firmlysecured. If it comes out, do not use it.OPERATION008819The proper fastening torque may differ depending uponthe kind or size of the screw/bolt, the material of theworkpiece to be fastened, etc. The relation betweenfastening torque and fastening time is shown in thefigures.M12M10M8806040200(14)(29)(58)(43)1.0 2.0 3.0Standard boltN.m(ft.lbs)M12(1/2”)M10(3/8”)M8(5/16”)(S)Fastening timeFastening torqueProper fastening torque0088240 1.0 2.0 3.080604020(14)(29)(58)(43)N.m(ft.lbs)High tensile boltM10(3/8”)M8(5/16”)(S)Fastening timeFastening torqueProper fastening torqueM10(3/8”)M8(5/16”)008822Hold 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.NOTE:• Use the proper bit for the head of the screw/boltthat you wish to use.• When fastening screw M8 or smaller, carefullyadjust pressure on the switch trigger so that thescrew is not damaged.• Hold the tool pointed straight at the screw.• If you tighten the screw for a time longer thanshown in the figures, the screw or the point of thedriver bit may be overstressed, stripped, damaged,etc. Before starting your job, always perform a testoperation to determine the proper fastening time foryour 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 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.1.
