6Switch action (Fig. 4)CAUTION:• Before inserting the battery cartridge into the tool,always check to see that the switch trigger actuatesproperly and returns to the “OFF” position whenreleased.To start the tool, simply pull the switch trigger. Tool speedis increased by increasing pressure on the switch trigger.Release the switch trigger to stop.Lighting up the lamp (Fig. 5)CAUTION:• Do not look in the light or see the source of lightdirectly.Pull the switch trigger to light up the lamp. The lampkeeps on lighting while the switch trigger is being pulled.The lamp goes out just after the switch trigger isreleased.NOTE:• Use a dry cloth to wipe the dirt off the lens of lamp. Becareful not to scratch the lens of lamp, or it may lowerthe illumination.Reversing switch action (Fig. 6)This tool has a reversing switch to change the directionof rotation. Depress the reversing switch lever from the Aside for clockwise rotation or from the B side for counter-clockwise rotation.When the reversing switch lever is in the neutral position,the switch trigger cannot be pulled.CAUTION:• Always check the direction of rotation before operation.• Use the reversing switch only after the tool comes to acomplete stop. Changing the direction of rotationbefore the tool stops may damage the tool.• When not operating the tool, always set the reversingswitch lever to the neutral position.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 bit or socket bit(Fig. 7)Use only bits that has inserting portion shown in the fig-ure.For tool with shallow bit hole006348For tool with deep bit hole011405Procedure (1)To install the bit, pull the sleeve in the direction of thearrow and insert the bit into the sleeve as far as it will go.Then release the sleeve to secure the bit. (Fig. 8)Procedure (2)In addition to the procedure (1) above, insert the bit-piece into the sleeve with its pointed end facing in.To remove the bit, pull the sleeve in the direction of thearrow and pull the bit out. (Fig. 9)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 (Fig. 10)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.OPERATIONCAUTION:• Do not cover vents, or it may cause overheating anddamage to the tool. (Fig. 11 & 12)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.(Fig. 13 & 14)Hold 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/bolt thatyou wish to use.• When fastening M8 or smaller screw, choose a properimpact force and carefully adjust pressure on theswitch trigger so that the screw is not damaged.• Hold the tool pointed straight at the screw.• If the impact force is too strong you tighten the screwfor a time longer than shown in the figures, the screw orthe point of the driver bit may be overstressed,stripped, damaged, etc. Before starting your job,always perform a test operation to determine theproper 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.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.
