Thetiltinghandleisusedtotiltthebladeforbevelcutting.Turn
the handle clockwise to tilt toward the left, and counter clockwise
totilttowardtheright.
THE LOCKING KNOB. (PIC. 29)
The locking knob is used to lock the required blade height and tilt
positions.Toloosenthelockingknobturnitcounterclockwise.
Beforeturningthetablesaw“ON”,besurethatthelockingknob
is securely tightened so that the blade will not shift during the
tablesawoperation.
THE RIVING KNIFE. (SEE SPECIFIC SAFETY
INSTRUCTIONS FOR CORRECT SETTING)
The riving knife ensures that when a cut is made the two pieces
of timber on either side of the blade do not close up onto the
blade.Thispreventspossiblebindingandkickback.
THE RIP FENCE. (PIC. 30)
The rip fence is used to guide the material when making long
cuts,usuallycuttingalongthegrainNEVERripfreehandwithout
thefenceinplaceandsecurelylocked.
THE MITRE GAUGE. (PIC. 31)
The mitre gauge is typically used to guide the work piece when
crosscutting(acrossthegrain)andcanbesettocutatvarious
angles.Itcanbeusedineitherofthegroovesmachinedinthe
table.Alwaysensurethatitislockedsecurelywheninuse.
CROSS CUTTING (PIC. 32)
Crosscuttingiscuttingwoodacrossthegrainat90°orsquare
withboththeedgeandtheflatsideofthewood.
MITRE CROSS CUTTING (PIC. 33)
Mitre crosscutting is cutting the wood at an angle other than
90°withtheedgeofthewood.Followthesameproceduresas
youwouldforcrosscutting.Butadjustthemitregaugetothe
desiredangle.
BEVEL CROSS CUTTING (PIC. 34)
Bevel cross cutting is the same as cross cutting except that the
woodisalsocutatanangleotherthanat90°withtheflatside
ofthewood.Followthesameproceduresasyouwouldforcross
cutting.Butadjustthebladetothedesiredangle.Usethemitre
gauge in the groove to the right of the blade to avoid the blade
guardfrominterferingwiththecut.
WARNING!
When cross cutting, mitre cutting, bevel cutting and when
rabbeting across the end of a narrow work piece always use the
mitregauge.NEVERmakethesecutsfreehand(notusingthe
mitregaugeortheotherdevices)becausethebladecouldbind
causing a kickback or causing your hand or fingers to contact
theblade.
ALWAYS lock the mitre gauge when in use. Remove the rip
fence from the table when not in use. Make sure the blade
safetyguardismountedforallthroughsawingoperations(the
bladecutsthroughtheentirethicknessoftheworkpiece).The
bladeshouldextendapproximately3.5mm(1/8”)abovethetop
oftheworkpiece.
COMPOUND MITRE CUTTING (PIC. 35)
Compound mitre cutting is a combination of mitre cutting and
bevelcrosscutting.Thecutismadeatanangleotherthan90°
toboththeedgeandtheflatsideofthewood.Adjustthemitre
gauge and the blade to the desired angle and be sure that the
mitre gauge is locked
REPETITIVE CUTTING (PIC. 36)
Repetitivecuttingiscuttinganumberofpiecesthesamelength,
withouthavingto markeachpiece.The safeway toperform
repetitive cutting, is to set the rip fence to give the required
length, and to be clear of the front of the blade (Pic. 36).When
the cut is made, the end of the work piece is clear of the rip
fencebutattherequiredlength.
NEVERusetheripfenceasalengthstopbecausethecutoff
piece could bind between the fence and the blade causing a
kickback.
USING THE RIP FENCE (PIC. 37)
Ripping, bevel ripping, and rabbeting are done using the rip
fence.
RIPPING
Rippingiscuttingapieceofwoodwiththegrainorlengthwise
(Pic. 37).Thisisdoneusingtheripfence.Positiontheripfence
tothedesiredwidthoftheripandlockitinplace.Beforestarting
to rip be sure that the rip fence is parallel to the saw blade, and
thattherivingknifeisproperlyalignedwiththesawblade.When
rippinglongboardsorlargepanelsalwaysuseaworksupport.
Hold the piece against the fence and feed it through the blade
withasmooth,steadypressure.Whentherippingwidthiswider
than150mm(6”)useyourrighthandtofeedtheworkpieceuntil
itisclearofthetable.Useyourlefthandonlytoguide,notto
feedtheworkpiece.
BEVEL CUTTING. (PIC. 38)
Whenbevelrippingmaterial150mm(6”)ornarrowerusethe
fence on the right side of the blade only (Pic. 38).
BLADE REPLACEMENT (PIC. 39)
Removethebladeguardandthetableinsert(Pic. 39.1)After
fully releasing the lock handle, turn the elevating handle in
clockwise direction to raise the blade to its highest position.
Removethebladefixingnutandtheouterflangeandremove
the blade (Pic.39.2).Ensurethatthemotorshaft,blademounting
arbour, inner and outer flanges and the securing nut are clean
andfreefromsawdustbuildup.Fitthenewblade(Besurethat
the teeth are facing downwards when viewed from the front
ofthe machine).Ensurethatthe flangesareclean andfitted
thecorrectwayround.Securethebladeinplacebyusingthe
securing nut (Pic.39.3) Re-fitthetableinsertandsecureinplace
withthecrossheadscrews.Re-fitthebladeguardensuringthat
itoperatescorrectly.Checkthealignmentoftherivingknifeas
detailedinthespecificsafetyinstructions.Beforeswitchingthe
table saw ON, make sure the blade guard is correctly installed
