The blade has been set at the factory to be at an angle of
90° to the table.To check the angle elevate the bladeto its
highest position and using an engineers square or a set square
positioned against the table and the blade, check that the angle
isat90°(Pic. 6).Ifadjustmentisrequiredcarefullyturnthetable
sawover andremove thebottom coverplate.Identifythetilt
angle operating screw (Pic. 7).Theoperatingscrew hastwo
setsof adjustmentandlocking nutsfitted.Thesetof nutsat
themotorendofthescrew,areforsettingthebladeat90°to

SETTING THE BLADE AT 90° TO THE TABLE (PICS.
7 TO 9).
Loosen the lock nut (Pic. 8.1) using two wrenches, one for the
lock nut and one for the adjustment nut (Pic. 8.2) on the motor
end of the operating screw (Pic. 7) and turn the adjustment
nut until the blade is at the 90° to the table. Then turn the
lock nut (while holding the adjustment nut in position) to fix
the adjustmentnut in place. Check the position of the angle
indicatorpointer against the angle scale and adjust to 0° by
looseningthecrossheadscrewandsettingthepointeron0°on
the angle scale (Pic. 9).
SETTING THE BLADE AT 45° TO THE TABLE (PICS.

To check the angle, elevate the blade to its highest position and
usingthetilthandletiltthebladeasfaras itwillgo.Usinga
suitable set square, check the angle of the blade to the table
is at 45°(Pic. 10).If adjustmentis required,locatethe set of
adjustment and locking nuts on the tilt angle operating screw
furthest away from the motor (Pic. 7).Loosenthelocknut(Pic.
11.1) using two wrenches, one for the lock nut and one for the
adjustment nut (Pic. 11.2) and turn the adjustment nut until the
bladeisat45°tothetable.Thenturnthelocknut(whileholding
theadjustmentnutinposition)tofixtheadjustmentnutinplace.
Check the position of the angle indicator pointer against the
anglescaleitshouldnowalignwiththe45°mark.
CHECKING THE BLADE ALIGNMENT (PICS. 12 TO
15)
To check that the blade is set parallel to the two mitre gauge
guidegroovesmachinedinthetable(oneoneithersideofthe
blade).Elevatethebladetoitshighestpointandmarkan“X”on
oneoftheteethwhichisset(Bent)totheleftandtothefront
of the blade slot in the table insert (Pic. 12).Positionthehead
of the combination square in the groove and adjust the blade
of the square so that it just contacts the tip of the marked tooth
(Pic. 13).Slidethecombinationsquaretowardstherearofthe
