Blade height adjustment (fig. F)
The blade can be raised and lowered by turning the combined elevating
and traverse handle (6).
• Loosen the blade level locking ring (10) and set the blade to the
required height.
• 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.
• Tighten the locking ring (10).
• For clarity the guard has been lifted in the drawing to show this
setting. Before sawing ensure that the guard is in the correct
position.
• Once the blade guard touches the table, do not lower the
blade any further.
Adjusting the blade angle (fig. G1 - G5)
Right angle adjustment
The machine has an adjustable stop at 0° for easy right angle adjustment
(fig. G1).
• Release the bevel locking handle (13) and set the blade to 0°, creating
a right angle to the table.
• Tighten the bevel locking handle.
• Place a set square on the table and up against the blade (fig. G2).
Do not touch the tips of the blade teeth with the square.
• If adjustment is required, proceed as follows:
• Adjust the eccentric bolt (43) securing the stop (44) to the machine
using a 17 mm spanner (fig. G1).
• Once the blade is at a right angle, check that the bevel indicator (45)
indicates 0° on the bevel scale (12) (fig. G3).
• If not, loosen the screws (46), move the scale (12) to read 0° and
tighten the screws (fig. G1).
Blade bevel adjustment
The machine has an adjustable stop at 45°, and has the facility to cut
beyond the stop to 47° (fig. G4).
• Release the bevel locking handle (13) and bevel the blade to 45° (fig. G1).
• Tighten the bevel locking handle.
• Check the angle of the blade to the table using a protractor; the angle
should be exactly 45° (fig. G5).
• If required, adjust the eccentric bolt (47) securing the stop (48) to the
machine using a 17 mm spanner (fig. G1 & G4).
Replacing the saw blade (fig. B5, C3 - C9 & H1 - H3)
The teeth of a new blade are very sharp and can be
dangerous.
• Remove the upper blade guard (3) (fig. C9).
• With the blade in ripping position i.e. locked in the centre of the table,
turn the saw on its side as shown (fig. B5).
• Lower the blade by loosening the blade level locking ring (10) and
turning the combined elevating and traverse handle (6)
counterclockwise. Retighten the blade level locking ring (fig. C3).
• Loosen the screws (24 & 25) (fig. C4). Remove the blade guard (26) by
first lifting the upper part (fig. C5), then sliding the guard forward to
clear the open-ended slots (27) for lifting of the lower part (fig. C6).
• Remove the riving knive (8) by loosening the bolts (28) using the 13 mm
spanner (29) (fig. C7).
• Place the 4 mm Allen key (49) into the end of the blade arbor (51) and
the 22 mm spanner (50) onto the nut (52) (fig. H1).
• The blade nut has a left-handed thread, therefore holding the Allen key
firmly, turn the spanner clockwise to loosen.
• Remove the nut (52) and the outer clamp washer (53) (fig. H2).
• Remove the old blade carefully by easing it off the inner clamp washer
(54) (fig. H3).
• Place the new blade (9) onto the inner clamp washer (54), ensuring that
the teeth are pointing towards the front of the machine.
• Replace the outer clamp washer (53) which will require rotating to find
the correct position (fig. H2).
• Replace the nut (52) and tighten whilst holding the arbor (51) (fig. H1 & H2).
• Replace the riving knive (8) (fig. C7). Tighten the bolts (28) securely.
• Replace the blade arbor protection guard (26) by first placing the open-
ended slots (27) over the screws (25), then sliding the guard rearward
to align the recesses (30) for placement over the screws (24) (fig. C8).
• Retighten the screws (24 & 25).
• Put the saw into the upright position.
• Replace the upper blade guard (3) (fig. C9).
Adjusting the fence parallel to the blade for ripping (fig. J)
• Loosen the fence bracket locking knob (42) and the fence clamping
knob (37).
• Slide the complete assembly towards the blade until the fence (34) is
just touching the blade.
• Adjust the fence quadrant (33) until the fence is just touching the blade
teeth at the front and rear to ensure it is parallel to the blade.
• Tighten the fence bracket locking knob and check that the fence is still
parallel.
• Tighten the fence clamping knob (37). The pointer on the quadrant
should now read 90°.
After having used the assembly in the mitre position, re-set the
fence for ripping by following the above procedure to ensure
accuracy.
Instructions for use
• Always observe the safety instructions and applicable regulations.
• Install the appropriate saw blade. Do not use excessively worn
blades. The maximum rotation speed of the tool must not
exceed that of the saw blade.
• Do not attempt to cut excessively small pieces.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
• Make sure all locking knobs and clamp handles are tight.
• The tool is supplied with a 215 mm sawblade. Always use this
type of blade when performing ripping applications.
• Never use your saw for freehand cuts!
• Never use your saw for slotting!
• Do not saw warped, bowed or cupped workpieces. There
must be at least one straight, smooth side to go against the rip
fence or mitre fence.
• Always support long workpieces to prevent kickback.
• Do not remove any cut-offs from the blade area while the
blade is running.
The attention of UK users is drawn to the "woodworking
machines regulations 1974" and any subsequent amendments.
Ripping mode (fig. K1 & K2)
To perform standard saw bench operations, the blade traverse must be
locked in central position.
• Loosen the blade level locking ring (10) (fig. K1).
• Take hold of the combined elevating and traverse handle (6) and twist it
clockwise to release the blade from its locked position at the rear.
