WARNING:
TheuseofHSSsawbladesisprohibited;useonlycarbidetipped
sawblades.
Thesawbladeteethmustpointincuttingdirection(down)
Alwayswearsuitablegloveswhenhandlingsawblades.
Wheninstallingorchangingsawblade,alwaysdisconnectsaw
frompowersource,unplug!
Pushtheslidingtabletothefrontandopenthelowersawblade

Theravingknifehastobeadjustedinsuchawaythatoverits
entirelengththegapbetweensawbladeandravingknifedoesnot
exceedmin.3mmandmax.8mm(Fig25).



Theheightsettinghastobeadjustedinsuchawaythatthe
sawguardbottomneverexceedsmorethan3mmabovethe
highestplacedsawbladetooth.
Afterheightadjustmentalwayslocksthecentralbolt(Q).
Theravingknifeissideadjustedexworks.
The4littleadjustmentscrewsareusedfortheexactsettingofthe
ravingknifeinlinewiththesawblade.

Forslottingorgroovingaspecialravingknifeisneeded.
Theravingknifehastobeadjustedinsuchawaythattheupper
partoftheravingknifeisneversetlowerthanthehighestsaw
toothinuse.
Neverremovethisravingknife.
Kickbacksaresevereandverydangerous.
Nosubmergedcutsbyremovingtheravingknifeand/orsawguard
maybeperformed.

7.3Mountingthesawguard

Eachtimethemainsawbladeisreplacedbyanewone,orevena
newlysharpenedsawblade,thescorerhastobeadjustedto
matchthemainsawbladeteethwidth.
Itisveryimportantthatthisisdoneinthecorrectwaytoensurea
cleancut,freeofsplintering.
Thesuppliedscoringsawbladehastaperedteeth.Cuttingdepth
alsoadjustscuttingwidth.
Beforeanylateraladjustmentcanbedonethelaterallock(R)has
tobeloosened.
Thelateralmovementofthescorersawbladeisachievedby
turningtheexcenter(S),lockagainafteradjustment(R).

7.6Slidingtablesetup
Whenloadingpanelsandwhencuttingusingtheparallelfencethe
slidingtableshouldbelocked.
Tolockthetableengagetheindexpinonthefrontendofthe
slidingtable.
Ifoveralongperiodoftimemanyshortmovementsofthesliding
tablearemadebye.g.crosscuttingsolidwood,thenitispossible
thattheballcarrierbetweentheupperandlowerpartofthe
slidingtablewillmove.
Thismeansitwillnolongerbecorrectlypositionedtoallowthe
slidingtabletoslidethroughitsfullcourse.
Theoperatorwillfeelresistanceintheslidingtablemotionand
thefullstrokewillnotbeachieved.
Thiseffectcanbecorrectedsimplybypushingthetablewithafew
short,lightpushesagainstthebufferstopattheend,untilthe
positionoftheballcarrierisadjustedandthetablecanbemoved
againalongitsfullstroke.
Itisrecommendedtocleantheslidingtableonceaweek,andto
removeallsawdustandchipswhichgraduallyslowdownthe
slidingtable.
Afteralldusthasbeenblownoff,thinoil,suchasWD‐40,should
besprayedontothesteelguiderodsonboththeupperandlower
partoftheslidingtable.
Neveruseathickoilorgrease!

7.7Crosscuttablesetup

adjustments.
Tocheckthesettings,putthestopatacertainmeasureandcutoff
asample.
Measuretheexactlengthofthesample,unlockthescrewwhich
holdsthefencepivotingT‐nutandmovethefenceuntilthe
measurementcorrespondstothelengthofthepreviouslycut
length.
Whenusingthetelescopicextension,thematerialstophastobe
settotheveryendtomakethedifferentscalescorrespondwith
