3.6 WEDGE REGULATION
To ensure the dividing wedge is in the correct position, keep
it at a distance of between 3mm - 8mm from the tooth of the
blade. Should this not be the case, loosen the screw which
holds it attached to the arm and move it to the aforementioned
distance (Fig. 17).
3.7 ANGLE AJUSTMENT
Before the power tool is shipped from the factory,it is ajusted
for 0°,left angle 45°
bevel cutting angle with stopper screw.
When changing the ajustment, change the height of the stopper
screw 53 by turning (Fig. 18).
4 USE
After having performed all the above procedures and
operations, you may begin cutting.
WARNING: Always keep hands away from the cutting
area and do not try to approach it when the machine
is running.
NOTE: Please remove the support square when
cutting on the lower work surface to ensure easier
return of the head to its original position.
4.1 USE AS A CUTTING-OFF MACHINE (cutting on
the lower work surface) (Fig.10)
– Release the head, by unscrew the block pin 19.
– Raise the machine head as far as possible.
– Secure the workpiece fi rmly against the angular bearings
30 of the base with your left hand, thus ensuring absolute
immobility during cutting.
– Put your right hand on the handgrip 1 and press the button
9 in order to release the head.
– Actuate the motor by pressing the start button 2 on the
handgrip.
– Lower the head and gradually bring the blade into contact
with the workpiece.
– Complete cutting and raise the head to its original
position.
– Turn off the motor by release the main switch button 2.
4.2 USE AS A CIRCULAR SAW
(cutting on the upper work surface) (Fig. 11)
WARNING: When working on the upper surface, it
is absolutely necessary to install the lower safety
guard supplied.
WARNING: The machine is equipped with a
pusher the dimensions and shape of which are
in compliance with the Safety Standards (Fig. 15).
When the machine is used as DISK SAW (thus using
the upper table for the machining operations), such
fi tting MUST absolutely be used.
Hold pusher from side A while side B must be put
in contact with the piece to be cut as shown in the
fi gure.
The piece to be cut can be pushed by means of the
pusher which simultaneously drives and rest it on
square C thus enabling to keep hands away from
the blade cutting area.

CAUTION: The rip fence fi x parallel to the blade.
CAUTION: Do not rotate the Rotating bearing with
putting the handgrip down.
–
When the motor is off, lower the machine head and block
it by means of the block pin 19.
– Adjust the height of the upper work surface according to
the cutting height desired and adjust the bearing bracket
as described in the paragraph "ADJUSTMENTS".
– Check that the removable upper shield is not faulty: after
having lifted it slightly, it must return to its orginal position,
covering the blade completely.
– Start the motor as described at point 4.1, and lock the main
switch in "ON" position by means of the locking device 51
in the lower zone of the handgrip.
– Place the workpiece to be cut on the work surface, placing
it laterally against the bracket and then move the workpiece
slowly and gradually towards the blade.
CAUTION: The workpiece must always be held
fi rmly, paying attention not to hold it near the cutting
area.
– to turn off the machine, push the start button 2 of the main
switch, automatically release the locking device 51.
4.3 INSTALLATION AND/OR REPLACEMENT OF THE
BLADE (Fig. 12)
WARNING: This procedure must be carried out
only after having turned off the machine's motor by
release the main switch button 2.
– Release the movable shield 11 (Fig. 4) by pressing the pawl
40 and simultaneously raising the shield so as to uncover
the blade.
– Raise the upper surface as high as possible, by acting on
knob 52 (Fig.10).
– Remove the protection plug of the blade-holding shaft from
the cover of the electronic box.
– Use the two 6 mm. Allen wrenches supplied: insert one
wrench in terminal 41 of the driving blade-holding shaft
and the other one in the blade fi xing screw 42; then lo
osen the screw, keeping in consideration that the screw
thread is left-handed.
– Remove the external fl ange 43, remove the blade by
sliding it out from the lower part of the head and install a
new blade.
– Ensure that the blade's teeth are oriented in the direction
of the arrow on the blade itself.
– Then, remount the outer fl ange 43, tighten the screw 42
fi rmly, using the Allen wrenches supplied.
- Lower the upper surface to the required height and insert
the protection plug of the blade-holding shaft.
NOTE: The movable shield 11 (Fig. 4) will return
to the correct position automatically when the
machine head is lowered, without having to
reposition the pawl.
WARNING: Mount the protection plug to prevent
dust from entering.
