8FUNCTIONAL DESCRIPTIONCAUTION:• Always be sure that the tool is switched off andunplugged before adjusting or checking function onthe tool.Adjusting the depth of cutFig.1Place the tool on a flat surface. Loosen the lock leverand lower the tool body until the bit just touches the flatsurface. Tighten the lock lever to lock the tool body.Turn the stopper pole setting nut counterclockwise.Lower the stopper pole until it makes contact with theadjusting bolt. Align the depth pointer with the "0"graduation. The depth of cut is indicated on the scale bythe depth pointer.While pressing the fast-feed button, raise the stopperpole until the desired depth of cut is obtained. Minutedepth adjustments can be obtained by turning theadjusting knob (1 mm per turn).By turning the stopper pole setting nut clockwise, youcan fasten the stopper pole firmly.Now, your predetermined depth of cut can be obtainedby loosening the lock lever and then lowering the toolbody until the stopper pole makes contact with theadjusting hex bolt of the stopper block.Nylon nutFig.2The upper limit of the tool body can be adjusted byturning the nylon nut.CAUTION:Do not lower the nylon nut too low. The bit will protrudedangerously.Stopper blockFig.3The 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 depth ofcut, 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 with ascrewdriver or wrench. The stopper block is alsoconvenient for making three passes with progressivelydeeper bit settings when cutting deep grooves.CAUTION:• Since excessive cutting may cause overload of themotor or difficulty in controlling the tool, the depthof cut should not be more than 15 mm at a passwhen cutting grooves with an 8 mm diameter bit.• When cutting grooves with a 20 mm diameter bit,the depth of cut should not be more than 5 mm at apass.• For extra-deep grooving operations, make two orthree passes with progressively deeper bitsettings.Switch actionFig.4CAUTION:• Before plugging in the tool, always check to seethat the switch trigger actuates properly andreturns to the "OFF" position when released.• Make sure that the shaft lock is released before theswitch is turned on.To prevent the switch trigger from being accidentallypulled, a lock button is provided.To start the tool, depress the lock button and pull theswitch trigger. Release the switch trigger to stop.For continuous operation, pull the switch trigger andthen depress the lock button further. To stop the tool, pullthe switch trigger so that the lock button returnsautomatically. Then release the switch trigger.After releasing the switch trigger, the lock-off functionworks to prevent the switch trigger from being pulled.CAUTION:• Hold the tool firmly when turning off the tool, toovercome the reaction.Electronic functionFor model RP2300FC,RP2301FC onlyConstant speed control• Possible to get fine finish, because the rotatingspeed is kept constantly even under the loadedcondition.• Additionally, when the load on the tool exceedsadmissible levels, power to the motor is reduced toprotect the motor from overheating. When the loadreturns to admissible levels, the tool will operate asnormal.Soft start feature• Soft start because of suppressed starting shock.Speed adjusting dialFor model RP2300FC,RP2301FC onlyFig.5The tool speed can be changed by turning the speedadjusting dial to a given number setting from 1 to 6.Higher speed is obtained when the dial is turned in thedirection of number 6. And lower speed is obtained whenit is turned in the direction of number 1.This allows the ideal speed to be selected for optimummaterial processing, i.e. the speed can be correctlyadjusted to suit the material and bit diameter.Refer to the table for the relationship between thenumber settings on the dial and the approximate toolspeed.
