In the case of interruption - because of excess temperature-
waiting for the normal recovery (ca.10 min).
3.1 BLADE TENSION (figure 4)
Turn clockwise the knob B to the stop (until the complete packing of
the cup springs) avoiding overtightening.
If the tighten is too high, the blade tends to come
out from the guides; in this case, slightly loosen
the tension by turning of a turn the handwheel B
anticlockwise.
3.2 BAR STOP (Fig.5)
If you need to make more cuts pieces of the same length used the
bar stop supplied in order to avoiding repeat all the times the same
measure.
Screw rod E into the hole of the base and lock it with the nut F;
loosen the handwheel G and place the stop L at the required
distance from the blade; locked again the flyer G.
3.3 CUTTING ANGLE (Fig.6)
The sawing machine is enables to make cuts with an angle varying
between 0 ° and 45 ° (0 ° and 60 ° MT-125); simply loosen the knob
I and rotate the turntable to the respective latches.
For all other intermediate angles, rotate the turntable until the
indicator coincides M placed on it with the corresponding position
on the plate.
Then locked again the rotatable support.
3.4 CUTTING SPEED (figure 7)
Your sawing machine is equipped with, an electronic control
system which allows gradual and continuous variation of cutting
speed, adapting it to the type and size of material to be cut (see
CUTTING TABLE).
Then, in order to select the proper speed act on the drive or
increasing it or decreasing it according to your needs.
Example:
Stainless steel: 30 m / min position 1
Steels: 40-60 m / min position 2-3-4
Light alloys: 80 m / min position 6
Tubes and profiles: 70-80 m / min position 5-6
3.5 SLIDING BLADE GUIDE (Figure 8)
The sliding blade guide P with integrated protection that is attached
To zoom in or out blade guides you have to simply rotate slightly
with 10mm spanner head screws S.
4.2 OPERATION (figure 7)
If during processing were intervene the limiter, lightened slightly
the cutting pressure: this allows among others to safeguard the life
and performance of the blade and to get a cut that is always clean
Before starting each cutting operation, ensure by
means of a visual check that all guards are intact
and in the proper position.
It is therefore necessary to make the first three / four cuts possibly
on a piece full D.40-50mm, exerting pressure on the piece very
slight, increasing it gradually in subsequent cuts.
Between cut and another, during the positioning of the workpiece,
release the button A always, do not try to block it or alter in any way
the functional characteristics.
If after several consecutive cutting machine should suddenly stop,
do not be alarmed: is the thermal protector of the motor, that cuts
the power when the winding temperature reaches the threshold
limit defined the insulation class, avoiding damage to the engine.
(see 2.5 )
To facilitate the replacement of the blade and keep it guided to
better blade guides outside of the sawing machine are eccentric
and adjustable.
To make the cut, put yourself in front of the car, and challenged his
right hand grip.
Do not make a proper break-in procedure could
make irreparably compromise the precision
cutting blade.
To realize of what the correct pressure in normal operating
conditions defined by this manual (see CUTTING TABLE),
consider for example that the first cut of steel (es.C40) D.50mm full
must be made in about 4 minutes; after testing, the same
workpiece can be cut easily in about 2 minutes. A running-well
executed, results in a better cut quality, both as a finish that as
precision, and a longer life of the blade.
4.0 USE
They must always be placed in light contact of the same, but not
completely blocked.
In this case, release the button and wait for the automatic recovery,
which usually returns after a few minutes.
When all the procedures and operations described so far, you can
start working.
Press with the forefinger of his right hand at the start button (figure
4) and gradually lower the body of the car to get in touch gently the
blade with the workpiece.
The cruise control of your sawing machine is equipped with the
function includes motor protection, obtained by an amperometric
limiter that does not allow him to absorb a higher current than the
set, expressed by the maximum value of absorption programmed
4.1 RUNNING IN THE BLADE
Switch the main switch D on the position - in this way the machine is
ready to operate.
For best performance, the bi-metal blades that accompany your
sawing machine must undergo to a short break-in procedure.
Keep the left hand still far away from the cutting area and do not
seek in any way to reach during the cutting operations.
Start now to apply a progressive strain on the piece and finish the
cut.
3.6 BEARING blade guide (figure 9)
to your cutting machine, you can make the cut while maintaining
the guided part of the blade and necessary to fully protect the
unused processing.
Loosen the handle Q and slide the blade guide P so closer or
farther away from the workpiece, as shown in the figure.
If this is not done, it is uncovered a portion of the
blade not required for processing, which can create a
residual risk of contact with it, as well as affecting the
quality of the cut.

The following table specifies the cutting capabilities: - from 0 ° to 45
° for the MT-105, - from 0 ° to 60 ° for the MT-125 obtainable in
normal conditions of use described in this manual , and without the
interposition of any object between wheel clamp on the vice.
The dimensions indicated are intended as maximum
measurements that can be taken in a vice and are intended
only for tubes and profiles.
4.4 CUTTING CAPACITY
It is suggested for solid materials to reduce the maximum
diameter of cut of 30%.
4.5 CORRECT POSITIONING OF THE PIECE IN
THE CLAMP (FIG.11)
The pieces that have to be cut are inserted directly between the
jaws, without the interposition of other objects.
Never hold the pieces to be cut in your hand.
When cutting concerns profiles, plates or special applications,
refer to the examples shown in the figure.
4.6 CUTTING TABLE
