If the saw blade is not exactly at 90° to the fence:
• Loosen the two screws (53) and move the scale/head assembly left or
right until the blade is at 90° to the fence as measured with the square
(fig. H4).
• Lock the mitre clamping knob (9) (fig. A1).
• Tighten the two screws (53) (fig. H4).
Make sure the rear edge of the mitre scale keeps in contact
with the two location lugs (54) at all times.
Adjusting the riving knife (fig. A1, D1, J1 & J2)
The correct position is for the top of the riving knife (31) to be no more
than 2 mm below the highest tooth of the blade and the body of the radius
to be a maximum of 5 mm from the tips of the saw blade teeth (fig. J1).
• Loosen the table locking knobs, both main (37) (fig. D1) and additional (3)
(fig. A1), but do not take them off.
• Use the Allen key to remove the screw (55) from the rear table column
(fig. D1). Take the nut and washer off the other end of the screw.
• Remove the table.
• The riving knife (31) (fig. J1) is fastened by a large Allen screw (56)
towards the rear of the right-hand side under the table (fig. J2).
• To adjust the riving knife, loosen the Allen screw which allows both the
bracket to rotate and the riving knife to move up and down.
• After loosening, rotate the bracket and slide the knife either up or down
until the correct position is attained.
• Retighten the screw (56) firmly (fig. J2).
• Replace the table and replace the Allen screw assembly (55) (fig. D1).
• Set the table to the proper height needed.
• Tighten the table locking knobs (fig. A1 & D1).
Lubrication
This machine requires no additional lubrication. The bearings of the motor
are pre-lubricated and watertight.
• Avoid using oil or grease as this can cause clogging with sawdust and
chips and create problems.
• Clean the parts subject to accumulation of sawdust and chips
periodically with a dry brush.
Instructions for use
• Always observe the safety instructions and applicable regulations.
The attention of UK users is drawn to the "woodworking
machines regulations 1974" and any subsequent amendments.
• Ensure the material to be sawn is firmly secured in place.
• Apply only a gentle pressure to the tool and do not exert side
pressure on the saw blade. • Avoid overloading.
• Always remove the dust from the machine after using to
ensure the lower guard operates properly.
Prior to operation:
• 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.
Switching on and off (fig. A)
• To switch the machine on, press the on/off switch (1).
• To switch the machine off, press the on/off switch again.

Quality of cut
The smoothness of any cut depends on a number of variables, e.g. the
material being cut. Please see the chart below for the recommended saw
blades applications.
Ensure that the material does not creep while cutting; clamp it
securely in place. Always let the blade come to a full stop
before raising the arm. If small fibres of wood still split out at
the rear of the workpiece, stick a piece of masking tape on the
wood where the cut will be made. Saw through the tape and
carefully remove tape when finished.
Setting the mitre (fig. A1)
The mitre arm can be preset to 0°, 15°, 22.5°, 30° and 45° left and right.
It is also possible to set the mitre angle to 48°.
• Loosen the mitre clamping knob (8) and lift the positive stop lever (7)
to release the mitre arm (9).
• Move the arm to the required angle and lock it using the mitre clamping
knob (8).
• Align the mitre arm as shown in fig. H1 - H3 by moving the edge of the
arm to the required mark on the scale.
When mitre cutting, ensure that the off-cut is not wedged
between the blade and the fence, i.e. the off-cut angle is greater
than 90° to avoid that the off-cut is picked up by the blade.
Setting the bevel (fig. G1)
• Set the 45°/48° adjustment handle (50) to the required position.
- Out = 48°
- In = 45°
• Loosen the bevel clamp handle (12) and bevel the head to the left;
there are marked positions at 0°, 15°, 30°, 33.85° and 45°.
• Hold the head firmly and do not allow it to fall.
• Holding the head, lock the bevel clamp handle securely.
Sawing in mitre saw mode
It is dangerous to operate without guarding. Guards must be in position
when sawing.
Ensure that aluminum workpieces are clamped securely.
Vertical straight cross cut (fig. K)
• Loosen the mitre clamping knob (8) and lift the positive stop lever (7)
upwards.
• Engage the mitre latch at the 0° position and tighten the mitre clamping
knob.
• Place the wood to be cut against the fence (11). Take hold of machine handle and press in the head lock-up release lever (2).
• Pull down the head approximately 10 mm and release the lock-up lever.
• Switch on the machine and depress the head to allow the blade to cut
through the workpiece and enter the table slot.
• Allow the blade to cut freely. Do not force.
• After completing the cut, switch off the machine and return the head to
its upper rest position.
Vertical mitre cross-cut (fig. K & L)
• Loosen the mitre clamping knob (8) and lift the positive stop lever (7)
upwards (fig. K).
• Move the head left or right to the required angle. There are preset
positions at 15°, 22.5°, 30° and 45° (fig. L).
• If any intermediate angle or 48° is required hold the head firmly and
lock by tightening the mitre clamp knob.
• Always ensure that the mitre clamp knob is locked tightly before
cutting.
• Proceed as for a vertical straight cross-cut.
