- 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
cannot be used for intermediate angles.
Always make a trial cut in a piece of waste wood, to check for
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)
(it allows a ratchet-type action when full rotation of the handle is not
• Tilt the sawhead to the required angle on the bevel scale (69).
The pointer (70) is on the fixed cast part of the bevel bracket (71).
• 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)
released and raised, slacken the locking screw (72) in the rear of the
rotating table location plunger (8) (fig. K1).
• Place a set square (73) against the fence and along the blade as
shown in figure K2. The angle should be 90°.
• If adjustment is required, rotate the eccentric adjustment bush (74) until
the face of the saw blade is flat against the square (fig. K2).
• Tighten the locking screw (72).
• Check that the red marks (67) nearest the blade slot (50) are in line with
the 0° position (75) on the two scales (fig. H).
• If adjustment is required, loosen the screws (76) and bring the
indicators in line. The 45° position should now also be accurate.
If this is not the case, the blade is not perpendicular to the rotating
table (see below).
Adjusting the blade vertical to the rotating table (fig. L1 & L2)
• Ensure that the sawhead is to its extreme right-hand position with the
bevel clamp handle locked.
• Release and retract the lower guard.

engages behind the front edge of the table.
• Check that the fence is parallel to the blade. If not, then adjust as follows.
• Loosen the Allen screw (86).
• Adjust the fence so that it is parallel to the blade by checking the distance
between the blade and the fence at the front and rear of the blade.
• When the adjustment has been carried out, re-tighten the Allen screw
and check again that the fence is parallel to the blade.
• Tighten the knob (83).
• Use the 10 mm profile for ripping low workpieces to allow
access between the blade and the fence for the push stick.
• The rear end of the fence should be level with the front of the
riving knife.
Changing from saw bench to mitre saw mode (fig. D, E1 & E2)
• Remove the parallel fence (33).
• Turn the wheel (53) of the height adjuster (22) to provide maximum

Basic saw cuts
Sawing in mitre saw mode
It is dangerous to operate without guarding. Guards must be in position
when sawing. Always clamp the workpiece when cutting non-ferrous
metals. Use the DE3461 clamp.
General handling
- In the mitre saw mode, the sawhead is automatically locked in the
upper “park”-position.
- Squeezing the head lock release lever will unlock the sawhead.
- Never seek to prevent the lower guard returning to its park position
when the cut is completed.
- The minimum length of offcut material is 10 mm.
- When cutting short material (min. 190 mm to the left or the right of the
blade), the use of the optional material clamp is recommended.
- When cutting UPVC sections, a supporting piece made out of timber
with a complementary profile should be placed beneath the material
being cut to provide the correct level of support.
Vertical straight cross cut (fig. S)
• Set the rotating table to 0° and make sure that the locating plunger is
• Pull down the rotating table clamping knob.
• Place the wood to be cut against the fence. Take hold of the control
handle and press in the head lock release lever.
• Switch the machine on.
• Allow the blade to cut freely. Do not force.
• When the cut is completed, raise the sawhead to its rest position and
press the red stop button.
Do not allow the sawhead to jump back unaided to prevent
Mitre cuts (fig. T)
• Set the required mitre angle.
• Ensure that the rotating table clamp is tightly secured.
• Ensure that the depth stop limiter is correctly set to prevent the blade
cutting the table if the angle is not 45°.
• Proceed as for a vertical straight cross-cut.
Bevel cuts (fig. U)
• Release the bevel clamp handle (24) and tilt the head to the angle
• Tighten the bevel clamp handle.
• Proceed as for a vertical straight cross-cut.
Compound mitre
This cut is a combination of a mitre and a bevel cut.
The limitations are 45° mitre/30° bevel. Do not exceed these limits.
• Set the bevel angle and subsequently set the mitre angle.
Sawing in the bench mode
• Always ensure that the riving knife and blade guard are correctly aligned.
Ripping (fig. V)
• Set the blade to the correct height.
• The correct blade position is to have the tips of three teeth above the
top surface of the wood.
• Mount the parallel fence using either the 10 mm or the 62 mm profile.
The piece of wood between the fence and the blade is the retained piece.
• Switch the machine on.
• Slowly feed the timber underneath the front of the upper blade guard,
keeping it firmly pressed against the fence. Allow the teeth to cut and
do not force the timber through the blade. The blade speed should be
kept constant.
Always use a push stick.
• When the cut is finished, switch off by pressing the red stop button.
Bevel cuts (fig. W)
• Release the bevel clamp handle and set the blade to the required angle.
• In order to prevent material jamming between the blade and the fence,
position the fence to the left of the blade.
• Proceed as for vertical ripping.
Mitre cuts (fig. X1 - X3)
• To adjust the mitre fence, loosen the stop screw locknut (90) and
screw the stop (91) in or out until the mitre pointer reads 0° (fig. X1).
• Set the blade height and angle.
• Insert the slide bar (92) of the mitre fence into the groove (93) provided
in the left-hand side of the table (fig. X2).
• Loosen the mitre locking knob (94) and rotate the fence to set the
scale to the required angle (fig. X3).
• Tighten the mitre locking knob (94).
• Place the workpiece against the flat surface of the mitre fence.
Switch on and, holding the workpiece firmly, slide the fence along the
groove to take the workpiece into the blade. When the cut is
completed, switch off immediately.
Fence positions, saw bench mode (fig. Y)
- For ripping thin materials, use the 10 mm profile of the dual height
parallel fence and position the fence opposite the front edge of the
riving knife.
- For ripping thicker materials, use the 62 mm profile of the dual height
parallel fence.
- For cross-cutting narrow and short workpieces (fig. Y):
• Adjust the parallel fence with the low profile facing the blade and
install the rear of the fence in line with the leading edge of the blade.
• Set the workpiece against the mitre fence (at 0° or 90°) and push the
mitre fence to make the cut.
• To prevent small offcut pieces fouling against the blade, prepare a
tapered length of timber and clamp it on the rear edge of the
worktable close enough to the right-hand side of the blade so that
successive offcuts feed automatically to the right.
- For ripping narrow (< 120 mm) and long workpieces:
• Place the fence in rearmost position to maintain accuracy during
long cuts.
• Push the workpiece with both hands (one on each side of the blade).
• Use a push stick when close to the blade.
• Support long workpieces at the outfeed side.
- For ripping wider (>120 mm) workpieces:
• Adjust the fence forward as in figure Y if the material being cut tends
to jam between the blade or the riving knife and the fence.

Side extension table (fig. A6)
The side extension table increases the distance from the rip fence to the
blade to 600 mm or more, depending on the rod length fitted to the
machine and the clamped position of the table.
The side extension table must be used in conjunction with guide rails (35)
(option). The adjustable table is equipped with an engraved scale along its
front edge and mounted on a sturdy base which clamps to the guide rods.
• Fit the extension table to the right-hand side of the machine for
continuity of the distance scale on both tables.
