10 ENGLISHStopper block► Fig.4: 1. Depth pointer 2. Screw 3. Stopper pole4. Adjusting hex bolt 5. Stopper blockThe stopper block has three adjusting hex bolts whichraise or lower 0.8 mm per turn. You can easily obtainthree different depths of cut using these adjusting hexbolts without readjusting the stopper pole.Adjust the lowest hex bolt to obtain the deepest depthof cut, following the method of “Adjusting depth of cut”.Adjust the two remaining hex bolts to obtain shallowerdepths of cut. The differences in height of these hexbolts are equal to the differences in depths of cut.To adjust the hex bolts, turn the hex bolts. The stopperblock is also convenient for making three passes withprogressively deeper bit settings when cutting deepgrooves.CAUTION: When using a bit having total lengthof 60 mm or more, or edge length of 35 mm or more,the depth of cut cannot be adjusted as previouslymentioned. To adjust, proceed as follows:Loosen the lock lever and carefully adjust bit protru-sion below the tool base to the desired depth of cutby moving the tool body up or down. Then retightenthe lock lever to lock the tool body at that depth of cut.Keep the tool body locked at this position during use.Since the bit always protrudes from the tool base, becareful when handling the tool.Adjusting the lock lever► Fig.5: 1. Lock lever 2. ScrewThe locked position of the lock lever is adjustable. Toadjust it, remove the screw securing the lock lever. Thelock lever will come off. Set the lock lever at the desiredangle. After adjustment, tighten the lock lever clockwise.Switch action► Fig.6: 1. Switch triggerCAUTION:• Before plugging in the tool, always check to seethat the switch trigger actuates properly andreturns to the “OFF” position when released.To start the tool, simply pull the switch trigger. Releasethe switch trigger to stop.ASSEMBLYCAUTION:• Always be sure that the tool is switched off andunplugged before carrying out any work on thetool.Installing or removing the bit► Fig.7CAUTION:• Install the bit securely. Always use only thewrenches provided with the tool. A loose orovertightened bit can be dangerous.• Do not tighten the collet nut without inserting abit. It can lead to breakage of the collet cone.Insert the bit all the way into the collet cone and tightenthe collet nut securely with the two wrenches.Use the correct size collet cone for the bit which youintend to use.To remove the bit, follow the installation procedure inreverse.Changing the collet cone► Fig.8: 1. Collet nut 2. Collet coneCAUTION:• Use the correct size collet cone for the bit thatyou are going to use.• Do not tighten the collet nut without installing abit, or the collet cone may break.To change the collet cone, loosen the collet nut andremove. Replace the installed collet cone with desiredcollet cone. Reinstall collet nut.OPERATIONSet the tool base on the workpiece to be cut withoutthe bit making any contact. Then turn the tool on andwait until the bit attains full speed. Lower the tool bodyand move the tool forward over the workpiece surface,keeping the tool base flush and advancing smoothlyuntil the cutting is complete.When doing edge cutting, the workpiece surface shouldbe on the left side of the bit in the feed direction.► Fig.9: 1. Workpiece 2. Bit revolving direction3. View from the top of the tool 4. FeeddirectionNOTE:• Moving the tool forward too fast may causea poor quality of cut, or damage to the bit ormotor. Moving the tool forward too slowly mayburn and mar the cut. The proper feed rate willdepend on the bit size, the kind of workpieceand depth of cut. Before beginning the cut onthe actual workpiece, it is advisable to make asample cut on a piece of scrap lumber. This willshow exactly how the cut will look as well asenable you to check dimensions.• When using the straight guide, be sure to installit on the right side in the feed direction. Thiswill help to keep it flush with the side of theworkpiece.► Fig.10: 1. Feed direction 2. Bit revolving direction3. Workpiece 4. Straight guide
