• To remove, loosen the grommet with a screwdriver (52) and proceed in
reverse order.
Turning the sawhead and table over (fig. A2, E1 & E2)
• Withhold the saw table with one hand and push the table release lever (19)
to the left (fig. E1).
• Push the table downwards at the front and swing it over completely
until the motor assembly is uppermost and the indentation engages in
the retaining teeth of the table locking device (26).
• The head assembly is held down by a clamp strap at the front and a
height adjuster (22) at the rear (fig. A2).
• Remove the strap.
• Rotate the circular wheel (53) counterclockwise whilst holding down
the head until the "U"-shaped bracket (54) can be disengaged from its
seating (fig. E2).
• Swing the height adjuster up and push the rod (55) into the clip (56).
• Holding the head firmly, allow the spring pressure to take the head
upwards into its rest position.
Mounting the saw blade (fig. A1, F1 - F3)
• The teeth of a new blade are very sharp and can be dangerous.
• Always change blades with the machine in mitre saw mode.
• The maximum diameter blade that can be fitted is 250 mm.
The minimum diameter is 244 mm.
• Loosen the riving knife clamping knob (27) and allow the riving knife (30)
to swing downwards (fig. F1).
• Place the 6 mm Allen key into the end of the blade bolt (13) and the
two pins of the pin spanner (57) into the holes on the outer flange (14).
• The blade bolt has a left-handed thread, therefore holding the spanner
firmly, turn the Allen key clockwise to loosen.
• Remove the blade bolt (13) and remove the outer flange (14).
• If the blade bolt is too tight, turn the handle of the pin spanner (57) into
the guard and lock it there using a screwdriver (58) (fig. F2). This allows
to exert extra pressure on the Allen key.
• The blade (59) has a 30 mm bore, and is located on a step flange (60)
on the inner flange (61) (fig. F1).
• Press the guard retraction lever (12) and move the head down slightly
to release the lower guard (15) (fig. A1).
• Rotate the lower blade guard all the way up and hold it there.
• Make sure the inner flange and both faces of the blade are clean and
free of dust.
• Place the blade onto the step flange (60) on the inner flange (61),
ensuring that the teeth are pointing downwards (fig. F1).
• Carefully ease the blade into position and release the lower blade guard.
• Also ensure that the two projections (62) on the outer collar are seated
properly through the inner collar and onto the flats on the spindle.
• Tighten the blade bolt securely.
• Rotate the blade by hand to check that it rotates freely. If it fouls the
lower rear blade guard (9), retighten the crosshead screws (63) (fig. F3).
• Reposition the riving knife (30) in the upper rest position and tighten the
clamping knob (27) (fig. F1).
Adjusting the mitre saw mode depth limiter (fig. G)
The handle (64) is connected to a depth stop rod (21) which has an
eccentrically positioned adjustable bolt (65) with locknut (66). When the depth
limiter is engaged, the saw head cannot be pulled down completely (fig. G).
- Handle to the left = engaged, for use in mitre saw mode
(all angles except 0-45° mitre cross cut)
- Handle to the right = disengaged, for use in saw bench mode
• If the depth limiter needs adjustment, loosen the locknut (66)
and screw the bolt (65) in or out as required.

Adjusting the mitre angle in mitre saw mode (fig. A1, A2 & H)
The straight cross-cut and 45° mitre positions are pre-set.
• Lift the rotating table clamp (17), pull up the rotating table location
• Grip the control handle (20) (fig. A1), compress the guard retraction
• Turn the sawhead with its rotating table to the required position.
• Push down the rotating table clamp (17). The rotating table location
Using the red marks (67), the rotating table (16) can be set to any mitre
angle left or right between 0° and 45° (fig. H):
- angles between 0° and 30°: use the red marks nearest to the slot
- angles between 30° and 45°: use the outer red mark (68)
• Proceed as for pre-set positions. The rotating table location plunger
Adjusting the bevel position (fig. J)
The sawhead can be tilted from the vertical position to 45° left to enable
bevel cuts to be made at any angle between these two limits.
• Standing behind the machine, release the bevel clamp handle (24)
• Tilt the sawhead to the required angle on the bevel scale (69).
• Tighten the bevel clamp handle (24) and leave it in horizontal position.
Checking and adjusting the blade to the fence (fig. H2, K1 & K2)
• With the head in the vertical position and the bevel clamp handle (24)
• Place a set square (73) against the fence and along the blade as
• If adjustment is required, rotate the eccentric adjustment bush (74) until
• Tighten the locking screw (72).
• Check that the red marks (67) nearest the blade slot (50) are in line with
