7Adjusting the fastening torqueFig.9The fastening torque can be adjusted in 16 steps by turningthe adjusting ring so that the graduations are aligned withthe arrow on the tool body. The fastening torque isminimum when the number 1 is aligned with the arrow, andmaximum when the number 16 is aligned with the arrow.Before the actual operation, drive a trial screw into yourmaterial or a piece of duplicate material to determinewhich torque level is required for a particular application.ASSEMBLYCAUTION:• Always be sure that the tool is switched off and thebattery cartridge is removed before carrying outany work on the tool.Installing or removing the driver bit or drill bitFig.10Turn the sleeve counterclockwise to open the chuck jaws.Place the bit in the chuck as far as it will go. Turn thesleeve clockwise to tighten the chuck.To remove the bit, turn the sleeve counterclockwise.Installing the hookFig.11The 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 toolhousing on either side and then secure it with a screw. Toremove, loosen the screw and then take it out.Installing the bit holder (Optional accessory)Fig.12Fit the bit holder into the protrusion at the tool foot oneither right or left side and secure it with a screw.When not using the driver bit, keep it in the bit holders.Bits 45 mm long can be kept there.OPERATIONCAUTION:• Always insert the battery cartridge all the way until itlocks in place. If you can see the red part on theupper side of the button, it is not locked completely.Insert it fully until the red part cannot be seen. If not,it may accidentally fall out of the tool, causing injuryto you or someone around you.Hold the tool firmly with one hand on the grip and theother hand on the bottom of the battery cartridge tocontrol the twisting action.CAUTION:• Do not cover vents, or it may cause overheatingand damage to the tool.Fig.13Hammer drilling operationCAUTION:• There is a tremendous and sudden twisting forceexerted on the tool/bit at the time of holebreak-through, when the hole becomes cloggedwith chips and particles, or when striking reinforcingrods embedded in the concrete.First, turn the action mode changing ring so that thearrow on the tool body points to the marking. Theadjusting ring can be aligned in any torque levels for thisoperation.Be sure to use a tungsten-carbide tipped bit.Position the bit at the desired location for the hole, thenpull the switch trigger. Do not force the tool. Lightpressure gives best results. Keep the tool in position andprevent it from slipping away from the hole.Do not apply more pressure when the hole becomesclogged with chips or particles. Instead, run the tool at anidle, then remove the bit partially from the hole. Byrepeating this several times, the hole will be cleaned outand normal drilling may be resumed.Blow-out bulb (optional accessory)Fig.14After drilling the hole, use the blow-out bulb to clean thedust out of the hole.Screwdriving operationFig.15First, turn the action mode changing ring so that thearrow on the tool body points to the marking. Adjustthe adjusting ring to the proper torque level for your work.Then proceed as follows.Place the point of the driver bit in the screw head andapply pressure to the tool. Start the tool slowly and thenincrease the speed gradually. Release the switch triggeras soon as the clutch cuts in.CAUTION:• Make sure that the driver bit is inserted straight inthe screw head, or the screw and/or bit may bedamaged.NOTE:• When driving wood screw, predrill a pilot hole 2/3the diameter of the screw. It makes driving easierand prevents splitting of the workpiece.Drilling operationFirst, turn the adjusting ring so that the pointer points tothe marking. Then proceed as follows.CAUTION:• Pressing excessively on the tool will not speed upthe drilling. In fact, this excessive pressure will onlyserve to damage the tip of your bit, decrease thetool performance and shorten the service life of thetool.
