The head stops automatically each time the pointer 22 is
aligned with the corresponding position etched on the
graduated scale of the rotating plate.
For all intermediate positions, once the the index is in
alignment with the position on the plate, block the rotating
bearing by means of the two knobs 20 .
3.2 ADJUSTMENT OF CUTTING ANGLE - HEAD
ANGLE (Fig. 5)
The machine head can be tilted to a maximum of 45° to the
left. Release the knob 24 (on the rear part of the machine)
and tilt the head until it comes to rest on the stopper at an
angle of 45° (already calibrated during testing). Retighten
the knob 24 to securely block the head in place. For all
other intermediate positions, align index 25 on the rear of
the head with the corresponding position marked on the
graduated scale 23 of the swivel joint (Fig. 16) .
ATTENTION:
During double angle cutting (rotation plus head
tilting) hold the work piece securely to the
machine using the right hand and guide the
lowering of the head with the left hand (Fig. 16).
3.3 ADJUSTMENT/INSTALLATION OF BAR CLAMP
(ACCESSORY) (Fig. 6)
To cut work pieces of the same length, use the bar clamp
in order to avoid repeating the same measuring procedure
more than once.
Screw the bar 26 into the hole in the base and block it with
the dowel 27 : loosen the handwheel 28 and position the
clamp 29 at the appropriate distance from the blade; then
tighten the handwheel 28 .
3.4 ADJUSTMENT HEIGHT OF
UPPER WORK SURFACE (Fig. 7)
JUST FOR CIRCULAR SAW
ATTENTION: When working on the upper surface,
it is absolutely necessary to install the lower
safety guard supplied.
To install the safety guard with the head uplifted, place it
on the angular bearings 30 of the base. Then lower the
head and block the body in this position by means of the
block pin 19 .
To adjust the height of the upper work surface to obtain
desired cutting widths, follow the instructions below:
– loosen the two handwheels 32 ;
– move the bearing bracket 17 toward the blade;
– lower or lift the work surface using knob 53 ,
simultaneously observing the desired cutting height on
the graduated plate 33 ;
– tighten the handwheels 32 ;
2.4 POSITION/WORK STATION (Fig. 2-3)
Place the machine on a work bench or on a sufficiently flat
base/pedestal to ensure the best possible stability.
Should you wish to fix the machine in place, use the
special holes located on the base. These are available as
an optional.
Bearing in mind ergonomic criteria, the ideal height of the
bench or of the base should be such that the base surface
or the upper work surface is between 90 and 95 cm. from
the ground (see fig. 2).
Always ensure that there is at least 80 cm. of manoeuvring
space in all directions around the machine in order to
perform all necessary cleaning, maintenance and
adjustment operations safely with a sufficient amount of
space available (see fig. 3) .
CAUTION: Ensure the machine is placed in a
suitable position both in terms of environmental
conditions and lighting.
Always bear in mind that general environmental
conditions are of fundamental importance to
prevent accidents.
2.5 ELECTRICAL CONNECTIONS
Check that the electrical system to which the machine is
connected is earthed in compliance with current safety
regulations and that the current socket is in perfect condition.
The electrical system must be fitted with a magnetothermal
protective device to safeguard all conductors from short
circuits and overload.
The selection of this device should be in line with the
following electrical specifications of the machine stated
on the motor.
NOTE: Your mitre-saw’s electrical system is
equipped with an undervoltage relay which
automatically opens the circuit when the voltage
falls below a minimum pre-established limit and
which prevents the self-reset of machine
functions when voltage returns to normal levels.
If the machine stops involutarily, do not be
allarmed. Make sure that there has not been a
voltage failure in the electrical system.
3 ADJUSTING (Fig. 4-5-6-7-8)
ATTENTION: All the adjustment procedures
illustrated below must be performed when the
machine's engine is off.
3.1 ADJUSTMENT OF CUTTING ANGLE-HEAD
ROTATION (Fig. 4)
This mitre-saw can cut both to the left and to the right.
The pre-set positions are: 15° - 22°30' - 30° and 45°.
To position the machine as above, loosen knob 20 , release
the machine head by pushing the lever 21 downwards and
rotate the rotary support by using the handgrip 1 .
