Make sure that the ring (44) of the arbor nut (39) is against the
outer flange (fig. E1).
• Tighten the arbor nut (39) by turning counterclockwise.
Checking that the arm is parallel to the table top (fig. A2, D3 & E2)
• 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. E2).
• Release the levers (9) and (10) (fig. A1).
• Swing the arm so that the blade skims the table top (4) across its width.
• If required, adjust the front adjusting bolt (34) (fig. D3).
• 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 & E3)
• Bring the arm back to central position and tighten the riplock (15) (fig. A2).
• Place a steel square (45) against the blade body (fig. F3).
• If adjustment is required, proceed as follows:
• Remove the bevel pointer disk (46) by loosening the two screws (47).
• Loosen all three Allen screws that will be exposed in this way.
• 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 (46).
Checking that the crosscut travel is perpendicular to the fence
(fig. E4 & E5)
• Lock the blade in front of the fence (fig. E4).
• 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:
• With the mitre latch lever (9) engaged in 0° position, release the mitre
clamp lever (10) (fig. E5).
• Loosen the locknuts (48) on each side of the arm (fig. E5).
• To adjust the arm to the left, loosen the stud on the righthand side of
the arm and tighten the opposite stud.
• To adjust the arm to the right, loosen the stud 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).
Checking that the blade is perpendicular to the fence (fig. E6)
• Unlock the yoke clamp lever (49) press the yoke latch (50).
• Rotate the motor through 90° as shown.
• If the motor shows a certain play, tighten the nut (51).
• 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 (52) installed crosswise under the yoke.
• Insert the Allen key into the motor arbor.
• Adjust the blade position and tighten the bolts (52).
Mounting and adjusting the blade guard assembly (fig. F1 - F5)
The blade guard (3) is a multifunctional assembly which offers the following
safety features (fig. F1):
en - 5
- Upper guard (53) (fig. G1) and spring held rear guard (54) (fig. F2) for
full blade protection.
- Dust extraction adapter (55) for cross and rip cutting.
- Anti-kickback fingers (56) for use in ripping mode.
- Adjustable finger guard (57) for use when cross-cutting.
- Riving knife (58) to prevent the workpiece binding on the blade when
ripping.
• Release the bevel clamp lever (19) and pull out the bevel latch (21) (fig. D2)
to tilt the motor as shown for optimum access (fig. F3).
• Remove the guard retaining wing nut (59) and washer (60) (fig. F3).
• Loosen the locking screw (61) and turn the retaining bracket (62) anti-
clockwise until the spring held rear guard (54) can be lifted off its
support lug (63) (fig. F2).
• Unhook the two springs (64) at the top only.
• Rotate the unhooked rear blade guard (54) as shown (fig. F2).
• Lower the guard assembly over the blade (fig. F3).
• Secure the guard assembly using the wing nut (59) and washer (60)
(fig. F3).
• Bring the spring held rear blade guard (54) and the retaining bracket (62)
into their original position (fig. F2).
• 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. F2 - F5)
Adjusting the riving knife for ripping
• Loosen the two knobs (65) and slide the riving knife (58) down until the
tip is approximately 10 mm from the table top (fig. F2 & F4).
The riving knife should be correctly set; the distance between the
toothed rim and the riving knife (58) should be 1-3 mm (fig. F4).
Adjusting the anti-kickback fingers for (bevel) ripping (fig. F5)
• Loosen the knob (66) and lower the bracket (67) until the hold down
spring (68) just touches the surface of the workpiece.
• The tips of the anti-kickback fingers (56) should now be 3 mm below
the surface of the workpiece and the angle should now be as shown in
figure F5.
• For bevel ripping, loosen the Allen screw (69) and set the anti-kickback
fingers to the required angle.
Adjusting the riving knife, finger guard and anti-kickback fingers for
cross-cutting (fig. F2)
• For cross-cutting, adjust the riving knife and anti-kickback fingers up
and out of the way.
• Loosen the lever (70) to position the finger guard (57) just above the
workpiece and lock the lever (70).
Scale adjustments (fig. G1 - G5)
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. G1)
- Out-rip from left to right (fig. G2)
The pointer (71) indicating the ripping width on the rip scale (72) is
adjustable (fig. G3):
• Place the fence in rearmost position.
• Place a board of 24 mm against the fence.
• Unlock the yoke clamp lever (49), press the yoke latch (50) (fig. H1) and
position the motor in out-rip position (fig. G1).
• Move the yoke assembly along the radial arm until the blade just
touches the edge of the material.
