When using a cable reel, always unwind the cable completely.

Assembly and adjustment

WARNING: Prior to assembly and adjustment always unplug
the tool.
Unpacking (fi g. A1 & A2)
• Remove the saw from the packaging material carefully.
• The machine is fully assembled except for the blade, rip fence, upper
blade guard and table insert.
• Finalise the assembly following the instructions as described below.
• Put the push stick (15) on its place at the right-hand side of the
machine (fi g. A2).
• Adjust the feet (17) until the table (4) is level in all directions.
• Fully unwind the mains cable.
WARNING:
• Always keep the push stick in its place when not in use.
• Connect the plug to the mains outlet only just before starting
the application.
Mounting the saw blade (fi g. A1, A2 & B1 - B3)
WARNING: Ensure the machine is disconnected from the
power source.
WARNING: The teeth of a new blade are very sharp and can
be dangerous.
WARNING: The saw blade MUST be replaced as described
in this section. ONLY use saw blades as specified under
Technical Data. We suggest DT4226. NEVER fit other saw
blades.
• Raise the blade arbor to its maximum by rotating the control wheel (11)
clockwise (fi g. A1).
• Place the saw blade onto the spindle in the order shown in fi gure B1.
The outer fl ange (20) has a ø 30 mm raised boss which fi ts inside the
blade bore. Make sure the teeth point down at the front of the table.
• Hold the spindle using the open-ended wrench and tighten the arbor
nut (21) by rotating clockwise using the arbor wrench (fi g. B2).
• To remove the blade, proceed in reverse order.

WARNING: Always check the rip fence pointer and the riving
knife after having changed the blade.
Adjusting the saw blade (fi g. A2 & B3)
For optimum performance, the blade must be parallel to the mitre slots.
This adjustment has been made at the factory. To re-adjust:
• Turn the saw on its side.
• Using a 10 mm Allen key, slacken the bracket fasteners (22) slightly
(fi g. B3).
• Adjust the bracket (23) until the blade is parallel to the fence slot (18)
(fi g. A2).
• Tighten the bracket fasteners (22) to 11 Nm (fi g. B3).
Blade height adjustment (fi g. A1)
The blade can be raised and lowered by turning the combined elevating
and bevel control wheel (11).
• Make sure the top three teeth of the blade are just breaking through
the upper surface of the workpiece when sawing. This will ensure
that the maximum number of teeth are removing material at any
given time, thus giving optimum performance.
Mounting the riving knife (fi g. A1 & C)
• Raise the blade arbor to its maximum by rotating the blade height
adjustment wheel (11) clockwise (fi g. A1).
• Slacken the locking bolt (24) a few turns using the supplied wrench
(fi g. C).
• Push and hold the bolt (24) inwards to release the spring-loaded
clamping mechanism.
• Align the slot (25) with the bolt (24) and insert the riving knife until the
top of the slot rests on the knob.
• Release the bolt (24) and tighten securely using the supplied wrench.
WARNING:
• When properly aligned, the riving knife will be in line with the
blade at the table top and at the top of the blade. Check
using a straight edge in all bevel and blade height positions.
• Do not attempt to fix the riving knife in any other position
than recommended. The distance between the riving knife
and the tips of the blade teeth must be at least 2.0 mm.
• Correct mounting and alignment of the upper blade guard (6)
on the riving knife is essential to safe operation!
• It is not allowed to fi t a different riving knife to the
specifi cation delivered with a thickness of 2.3 mm .
Fixing to Workbench (fi g. A2)
• The machine frame between the feet on each side (17) is provided
with two holes which allow fi xing on a workbench. Use the holes
diagonally.
• To improve the handling fi x the machine on a piece of plywood of min
15 mm thick.
• When in use the plywood sheet can be clamped to the workbench.
This allows easier transportation of the machine, by releasing the
clamps.
Mounting the table insert (fi g. D)
• Align the table insert (7) as shown and insert the tabs of the back of
the table insert into the holes on the back of the table.
• Press down the front of the table insert.
• The front of the table insert must be fl ush or slightly below the table
top. The rear should be fl ush with the table top. Adjust using the four
adjustment screws (26).
• Turn the locking screw (see insert in fi g. D) clockwise 90° to lock the
table insert in place.
