The saw blade (fig. G1 - G6)
Mounting the saw blade (fig. G1)
• The teeth of a new blade are very sharp and can be dangerous.
• The direction of rotation is indicated by the arrow on the motor.
• Hold the arbor using the Allen key (36) supplied with the machine and
remove the arbor nut (38) by turning clockwise with the open-ended
spanner (39).
• Mount the blade (43) between the outer flange (41) and the inner flange
(42) making sure that the lower teeth point to the rear of the machine.
Make sure that the ring (44) of the arbor nut (38) is against the
outer flange (fig. G1).
• Tighten the arbor nut (38) by turning counterclockwise.
Checking that the blade is perpendicular to the table top
(fig. A1 & G2 & G3)
• Bring the arm back to central position and tighten the riplock (15) (fig. A1).
• Place a steel square (45) against the blade body (fig. G2).
• If adjustment is required, proceed as follows:
• Remove the bevel pointer disk (46) by loosening the two screws (47).
• Slacken the Allen screw (48).
• Loosen the lock nuts (49) on either side of the bevel scale (21) (fig. G3).
• Adjust the unlocked screws (50) using an Allen key until the blade is flat
against the square.
• Firmly tighten all fasteners.
It is particularly important to tighten the central Allen screw.
• Replace the bevel pointer disk (46) (fig. G2).
Checking that the crosscut travel is perpendicular to the fence
(fig. G4 & G5)
• Lock the blade in front of the fence (fig. G4).
• Place a square (45) on a piece of board and against the fence and just
touching the blade as shown.
• Unlock the riplock, pull the blade towards you to check that the blade
traverses parallel to the square.
• If adjustment is required, proceed as follows:
• Loosen the mitre latch lever (9) and release the mitre clamp lever (10)
(fig. G5).
• Loosen the two adjustment screws (51).
• To adjust the arm to the left, loosen the stud on the righthand side of
the mitre latch lever and tighten the opposite stud.
• To adjust the arm to the right, loosen the stud on the lefthand side of
the mitre latch lever and tighten the opposite stud.
• Proceed in small steps and check the adjustment after each step with
the levers (9) and (10) engaged.
Do not overtighten the studs.
• Tighten the adjustment screws (51).
Checking that the blade is perpendicular to the fence (fig. G6 & G7)
• Loosen the yoke clamp lever (23) (fig. G6).
• Rotate the motor through 90° as shown (fig. G6). The yoke latch (52)
will automatically engage in this position (fig. G7).
• Place the blade against the fence and check that it is parallel to the fence.
• If adjustment is required, proceed as follows:
• Return the saw to 0° crosscut position.
• Loosen the two Allen screws (53) (fig. G7).
24
• Manipulate the screws (54) using an Allen key (55) to adjust the blade
position and check again.
• Tighten the Allen screws (53).
Mounting and adjusting the blade guard assembly (fig. H1 - H5)
The blade guard (5) is a multifunctional assembly which offers the following
safety features (fig. H1):
- Upper guard (56) (fig. H1) and spring held rear guard (57) (fig. H2) for
full blade protection.
- Dust extraction adapter (58) for cross and rip cutting.
- Anti-kickback fingers (59) for use in ripping mode.
- Adjustable finger guard (60) for use when cross-cutting.
- Riving knife (61) to prevent the workpiece binding on the blade when
ripping.
• Release the bevel clamp (20) and pull out the bevel latch (22) (fig. A2)
to tilt the motor as shown for optimum access (fig. H3).
• Remove the guard retaining wing nut (62) and washer (63).
• Loosen the locking screw (64) and turn the retaining bracket (65) anti-
clockwise until the spring held rear guard (57) can be lifted off its
support lug (66).
• Unhook the two springs (67) at the top only.
• Rotate the unhooked rear blade guard (57) as shown in figure H2.
• Lower the guard assembly over the blade (fig. H3).
• Secure the guard assembly using the wing nut (62) and washer (63).
• Bring the spring held rear blade guard (57) and the retaining bracket (65)
into their original position.
• To remove the guard assembly, proceed in reverse order.
The teeth of a new blade are very sharp and can be
dangerous.
Adjusting the guard assembly controls (fig. H2 - H5)
Adjusting the riving knife for ripping
• Loosen the two knobs (68) and slide the riving knife (61) down until the
tip is approximately 10 mm from the table top (fig. H2 & H4).
The riving knife should be correctly set; the distance between
the toothed rim and the riving knife should be 1-3 mm (fig. H4).
Adjusting the anti-kickback fingers for (bevel) ripping (fig. H5)
• Loosen the knob (69) and lower the bracket (70) until the hold down
spring (71) just touches the surface of the workpiece.
• The tips of the anti-kickback fingers (59) should now be 3 mm below
the surface of the workpiece and the angle should now be as shown in
figure H5.
• For bevel ripping, loosen the Allen screw (72) and set the anti-kickback
fingers to the required angle.
Adjusting the riving knife, finger guard and anti-kickback fingers for
cross-cutting (fig. H2)
• For cross-cutting, adjust the riving knife and anti-kickback fingers up
and out of the way.
• Loosen the lever (73) to position the finger guard (60) just above the
workpiece and lock the lever (73).
Scale adjustments (fig. G2, J1 - J4)
Rip scale
Ripping can be done with the motor in two positions. Each mode requires
its own direction of feed:
Position Direction of feed
- In-rip from right to left (fig. J1)
- Out-rip from left to right (fig. J2)
The pointer (74) indicating the ripping width on the rip scale is adjustable
(fig. J3):
