Mounting the saw blade (fig. A1, C1 & C2)
Ensure the machine is disconnected from the power source.
The teeth of a new blade are very sharp and can be
dangerous.
• Raise the blade arbor to its maximum by rotating the control wheel (10)
clockwise (fig. A1).
• Place the saw blade onto the spindle in the order shown in figure C1.
The outer flange (23) has a ø 30 mm raised boss which fits 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 (24) by rotating clockwise using the arbor wrench (fig. C2).
• To remove the blade, proceed in reverse order.
Always check the rip fence pointer and the blade guard splitter
after having changed the blade.
Parallel adjustment (fig. A2 & D)
For optimum performance, the blade must be parallel to the mitre slots.
This adjustment has been made at the factory. To re-adjust:
• Place the unit in upright position.
• Using a 10 mm socket wrench, slacken the bracket fasteners (25)
slightly (fig. D).
• Adjust the bracket (26) until the blade is parallel to the fence slot (14)
(fig. A2).
• Tighten the bracket fasteners (25) to 11 Nm (fig. D).
Blade height adjustment (fig. A1)
The blade can be raised and lowered by turning the combined elevating
and bevel control wheel (10).
• 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.
Adjusting the rip scale (fig. A1 & E)
• Remove the blade guard.
• Unlock the lock lever (12) by pulling it up (fig. A1).
• Unlock the bevel lock lever (11) and set the bevel angle to 0°.
• Move the fence (7) until it touches the blade.
• Lock the lock lever (12).
• Loosen the rip scale pointer screws (27) and set the pointer (28) to zero
(fig. E).
• Tighten the screws (27).
The rip scale reads correctly only when the fence is mounted to the right
of the blade.
Mounting the riving knife assembly (fig. A1, F & G)
• Raise the blade arbor to its maximum by rotating the blade height
adjustment wheel (10) clockwise (fig. A1).
• Slacken the two bolts (29) (fig. F).
• Align the slots (30) with the bolts (29) and insert the fence until the tops
ofthe slots rest on the bolts (fig. F).
• The thickness of the splitter (31) should be aligned with the thickness of
the blade. If adjustment is required, remove the blade guard and adjust
the shims (32).
• Mount the blade guard on the bolts.
• Retighten the bolts (29) securely.
• When properly aligned, the splitter 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.

• Correct mounting and alignment of the upper blade guard
(splitter) is essential to safe operation!
Mounting the table insert (fig. H)
• Align the table insert (6) 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 flush or slightly below the table
top. The rear should be flush or slightly above the table top.
Adjust using the four adjustment screws (33).
• Turn the locking screw (see insert in fig. H) clockwise 90° to lock the
table insert in place.
Never use your saw without the table insert.
Bench mounting (fig. A)
• Holes (2) are provided in all four feet to facilitate bench mounting.
Two different sized holes are provided to accommodate different sizes
of bolts. Use either hole; it is not necessary to use both. Always mount
your saw firmly to prevent movement. To enhance the portability,
the tool can be mounted to a piece of 12.5 mm or thicker plywood
which can then be clamped to your work support or moved to other
job sites and reclamped.
• When mounting your saw to a piece of plywood, make sure that the
mounting screws do not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping the
saw to any work surface, clamp only on the clamping bosses where
the mounting screw holes are located. Clamping at any other point will
interfere with the proper operation of the saw.
• To prevent binding and inaccuracy, be sure the mounting surface is not
warped or otherwise uneven. If the saw rocks on the surface, place a
thin piece of material under one saw foot until the saw is firm on the
mounting surface.
The mounting surface must have a 350 x 500 mm opening to
allow dust to escape.
Rail lock adjustment (fig. A1 & J)
The rail lock has been factory-set. If you need to re-adjust, proceed as
follows:
• Lock the lock lever (12) by pushing it down (fig. A1).
• Adjust the nut (34) on the underside of your saw until the gap between
the Belleville washers (35) closes (fig. J).
• Once the Belleville washers are almost touching, loosen the nut (34)
half a turn.
Bevel stop and pointer adjustment (fig. K1 & K2)
• Raise the blade to its maximum by rotating the blade height adjustment
wheel (10) clockwise (fig. K1).
• Unlock the bevel lock lever (11) by pushing it up and to the right.
• Loosen the bevel stop screw (36).
• Place a set square (37) on the table and up against the blade (38)
(fig. K2).
• Adjust the bevel angle using the bevel lock lever (11) until the blade is
flat against the square.
• Tighten the bevel lock lever (11).
• Turn the bevel stop cam (39) until it firmly contacts the bearing block
(fig. K1).
• Check the bevel angle scale. If adjustment is required, loosen the
pointer screw (40) and set the pointer to 0°.
• Tighten the pointer screw (40).
• Repeat the procedure at 45° for the 45° bevel stop, but do not adjust
the pointer.
