The saw blade (fig. G1 - G5)
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 supplied with the machine and remove
the arbor nut (38) by turning clockwise with the multifunctional spanner .
• Mount the blade (39) between the outer flange (40) and the inner flange
(41) making sure that the lower teeth point to the rear of the machine.
Make sure that the ring of the arbor nut (38) is against the
outer flange (fig. G1).
• Tighten the arbor nut (38) by turning counterclockwise.
Checking that the arm is parallel to the table top (fig. A1, A2 & G2)
• Tighten the riplock (15) with the blade in front position (fig. A2).
• Lower the blade until it only just touches the table top (4) (fig. G2).
• Release the levers (9) and (10) (fig. A1).
• Swing the arm so that the blade skims the table top across its width.
• Repeat this procedure with the blade in rear position and adjust the
rear bolt if required.
Checking that the blade is perpendicular to the table top (fig. A2 & G3 - G5)
• Bring the arm back to central position and tighten the riplock (15) (fig. A2).
• Place a steel square (42) against the blade body (fig. G3).
• If adjustment is required, proceed as follows:
• Remove the bevel pointer disk (43) by loosening the two screws (44)
(fig. G4).
• Loosen all three Allen screws that will be exposed in this way (fig. G5).
• Place an Allen key in the motor arbor and tap 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 (43) (fig. G4).
Checking that the crosscut travel is perpendicular to the fence (fig. G6 - G10)
• Lock the blade in front of the fence (fig. G6).
• Place a square (42) 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:
• With the mitre latch lever (9) engaged in 0° position, release the mitre
clamp lever (10) (fig. G7).
• Loosen the locknuts (45) on each side of the arm (fig. G7 & G8).
• To adjust the arm to the left, loosen the stud (46) on the righthand side
of the arm and tighten the opposite stud (fig. G9).
• To adjust the arm to the right, loosen the stud (47) on the lefthand side
of the arm 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 locknuts (48) (fig. G7 & G8).
• Adjust the pointer (48) on the mitre scale (49) so that it registers 0° (fig. G10).

Checking that the blade is perpendicular to the fence (fig. G11 - G13)
• Unlock the yoke clamp lever (50) press the yoke latch (51) (fig. G11).
• Rotate the motor through 90° as shown.
• If the motor shows a certain play, tighten the nut (52) (fig. G12).
• Place the blade against the fence and check that it is parallel to the fence.
• If adjustment is required, proceed as follows:
• Loosen the two bolts (53) installed crosswise under the yoke (fig. G13).
• Insert the Allen key into the motor arbor.
• Adjust the blade position and tighten the bolts (53).
Mounting and adjusting the blade guard assembly (fig. F1 & H1 - H3)
The blade guard (3) is a multifunctional assembly which offers the following
safety features (fig. H1):
- Front guard (54) (fig. H1) and spring held rear guard (55) (fig. H2) for full
blade protection.
- Dust extraction adapter (56) for cross and rip cutting.
- Anti-kickback fingers (57) for use in ripping mode.
- Adjustable finger guard (58) for use when cross-cutting.
- Riving knife (59) to prevent the workpiece binding on the blade when
ripping.
• Release the bevel clamp lever (34) and pull out the bevel latch (35)
(fig. F1) to tilt the motor as shown for optimum access (fig. H3).
• Remove the guard retaining wing nut (60) and washer (61).
• Loosen the locking screw (62) and turn the retaining bracket (63)
counterclockwise until the spring held rear guard (55) can be lifted off
its support lug (65) (fig. H2).
• Unhook the two springs (64) at the top only.
• Rotate the unhooked rear blade guard (58) as shown in figure H2.
• Lower the guard assembly over the blade (fig. H3).
• Secure the guard assembly using the wing nut (60) and washer (61).
• Bring the spring held rear blade guard (55) and the retaining bracket
(63) into their original position (fig. H2).
• 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. H4 & H5)
Adjusting the riving knife for ripping
• Loosen the two knobs (66) and slide the riving knife (59) down until the
tip is approximately 10 mm from the table top (fig. H4 & H5).
• Loosen the two screws (67) and set the riving knife to the correct
distance to the blade (fig. H4).
The riving knife should be correctly set; the distance between
the toothed rim and the riving knife should be 1-3 mm (fig. H5).
Adjusting the anti-kickback fingers for (bevel) ripping (fig. H4 & H6)
• Loosen the knob (68) and lower the bracket (69) until the hold down
spring (70) just touches the surface of the workpiece (fig. H4).
• The tips of the anti-kickback fingers (57) should now be 3 mm below
the surface of the workpiece and the angle should now be as shown in
figure H6.
• For bevel ripping, loosen the Allen screw (71) 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 (72) to position the finger guard (58) just above the
workpiece and lock the lever (72).
