Sawing in the Bench Mode

• Always use the riving knife.
• Always ensure that the riving knife and blade guard are correctly
aligned.
• Always ensure that the mitre saw is set and locked in 0° mitre.
WARNING: DO NOT cut any type of metal material.
Ripping (fi g. A2, T)
• Set the bevel angle to 0°.
• Adjust the saw blade height. The correct blade position is to have
the tips of three teeth above the top surface of the wood.
• Set the parallel fence to the required distance.
• Hold the workpiece flat on the table and against the fence. Keep
the workpiece approx. 25 mm away from the saw blade.
• Keep both hands away from the path of the saw blade.
• Switch the machine on and allow the saw blade to reach full
speed.
• Slowly feed the workpiece underneath the upper blade guard,
keeping it firmly pressed against the fence. Allow the teeth to cut,
and do not force the workpiece through the saw blade. The saw
blade speed should be kept constant.
• Remember to use the push stick (17) when close to the blade.
• After completing the cut, switch the machine off, allow the saw
blade to stop and remove the workpiece.
WARNING: Never push or hold the free or cut-off side of
the workpiece.
WARNING: Always use a push stick when ripping small
workpieces.
Bevel Cuts (fi g. U)
• 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 (fi g. V1–V3)
• To adjust the mitre fence, loosen the stop screw locknut (81) and
screw the stop (82) in or out until the mitre pointer reads 0°
(fig. V1).
• Set the blade height and angle.
• Insert the slide bar (83) of the mitre fence into the groove (84)
provided in the left-hand side of the table (fig. V2).
• Loosen the mitre locking knob (85) and rotate the fence to set the
scale to the required angle (fig. V3).
• Tighten the mitre locking knob (85).
• 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, Bench Saw Mode (fi g. W)
– For ripping thin materials, use the 11 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. W):
• 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.
40
• 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 W if the material being
cut tends to jam between the blade or the riving knife and
the fence.

DUST EXTRACTION KIT (FIG. A1, A2, A8)
This machine is provided with three dust extraction points for use in
mitre mode and two in bench mode.
• When sawing wood, always connect a dust extraction device
designed in accordance with the relevant regulations regarding dust
emission.
WARNING: Whenever possible, connect a dust extraction
device designed in accordance with the relevant regulations
regarding dust emission.
Connect a dust collection device designed in accordance with the
relevent regulations. The air velocity of externally connected systems
shall be 20 m/s +/- 2 m/s. Velocity to be measured in connection tube
at the point of connection, with the tool connected but not running.
A seperate dust kit is available as an option (DE3500)
1. Fit the dust extraction tube to the nozzles; the longer hose to upper
nozzle.
2. Connect the hoses to the three way connector.
Connecting - mitre saw position
• Connect one hose to the under-table guard.
• Connect one hose to the small diameter outlet and one to the
large diameter outlet using the corresponding spouts.
• Connect the hoses to the 3-way connector.
• Connect the single outlet of the 3-way connector to the hose from
the dust extractor.
Connecting - bench saw position
• Connect one hose to the small diameter outlet and one to the large
diameter using the corresponding spouts.
• Blank off the middle opening of the 3-way connector.
• Connect both hoses to the outer outlets.
MITRE SAW EXTRA SUPPORT/LENGTH STOP (FIG. A4)
The extra support and length stop can be mounted on the left-hand
side or on the right-hand side, or with two sets on either side.
• Fit the items 28–34 onto the two guide rails (29).
• Use the swivelling stop (30) for cross-cutting 210 mm wide boards
(15 mm thick).
ROLLER SUPPORT TABLE (FIG. A5)
In mitre saw mode, the roller support table can be mounted on the left-
hand side or on the right-hand side, or with two sets on either side.
In bench saw mode, it can also be mounted in front or at the rear of the
saw table.
