3.5 SLIDING BLADE GUIDE (Fig.8)
To perform the cut, move to the front of the machine and
grip the handgrip with your right hand.
The sliding blade guide
P
with integrated protection fitted
on your sawing machine is used to perform the cut while
guiding the necessary part of the blade and fully protecting
the part not used in the cutting process.
Keep your left hand away from the cutting area and on
no account try to reach it when cutting is in process.
Using the index finger of your right hand, press the run
button
A
(Fig.4) and gradually lower the machine body
until it comes lightly into contact with the part to be cut.
Slacken the knobs
Q
and slide the blade guide
P
so as to
move it closer to or further from the part to be cut, as
shown in the figure.
Now begin to apply gradual pressure on the part and
compete the cut.
ATTENTION : If this adjustment is not done, the part of
the blade not used in the cutting process will be
exposed and this will create an extra risk of contact,
besides altering the quality of the cut.
Always release button A between one cutting
operation and another, while you are positioning the
part. Do not try to block it or alter its functional
characteristics in any way.
Electronic version
3.6 BEARINGS BLADE GUIDE (Fig.9)
If the machine suddenly stops after numerous
consecutive cuts, do not be alarmed. The heat
protector device of the motor has been activated,
breaking the power supply when the temperature of
the coils reaches the threshold limit defined by the
insulation class, to prevent damage to the motor.
The blade-auide on the outside of the sawing machine are
eccentric and adjustable so as to simplify blade
replacement and to keep it guided as its best.
They must always touch the blade slightly, so that they
rotate when the blade passes, but must not be completely
locked.
In this case, release the button A and wait for
automatic reset which usually takes place after a few
minutes.
In order to approach or remove the eccentric bladeguide,
gently turn the head of the screws S using a 10 mm.
Wrenches key.
Your sawing machine is equipped with an electronic
speed governor which also includes a motor
protection function obtained by means of an
amperometric limiter. In this way it can not absorb an
amount of current greater than the set one, expressed
by the maximum value of absorption (see 2.5).
4.0 USE
4.1 RUNING IN THE BLADE
If the correct running in procedure is not performed,
the blade’s cutting precision may be irreparably
compromised.
If the limiter trips while the machine is in operation,
slightly decrease the cutting pressure in addition, this
enables to safeguard the blade life and performance
and to obtain always a sharp and clean cut.
To obtain the best performance, the bi-metal blades fitted
on your sawing machine must be run in for a short period.
For this reason the first two or three cuts should be done
where possible on a solid piece D.40-50 mm, using a very
slight pressure on the blade, and gradually increasing
pressure in subsequent cuts.
4.3 replacing the blade (Fig.9)
When you perform this operation, always wear
protective gloves to avoid contact with the teeth of the
blade.
To gauge the correct pressure in normal operating
conditions defined by this manual (see cutting table),
consider for example that the first cut on solid steel (eq.
C40) D.50 mm should be done in about 4 minutes.
-check that the main switch
D
is at position
O
;
-slacken the handle
Q
and slide the blade guide
P
as far
as it will go, following the direction on the arrow (Fig.8);
After running-in , the same piece may easily be cut in
about 2 minutes. If the running-in process is done correctly,
the finish and precision of the cut will be of better quality
and the blade will last longer.
-remove the protective casing unscrewing the four screws;
-slacken the blade tension, turning the handwheel
B
in a
anti-clockwise direction;
-using a 10mm. Spanner, slacken the exagonal nuts
R
on
the two blade guides on the outside of the blade (Fig.9);
4.2 WORKING(Fig.7)
-with the same spanner gently turn the head of the screws
on the same blade-guide in a anti-clockwise direction so
as to move the bearings far enogh away from the blade
to enable you to extract it easily from the guides ;
Two speed version
Push the green button “1”of the main switch
D
to anable
machine operation.
Electronic version
-extract the blade first from the guides and then from the
rubber coated pulleys;
Turn the main switch
D
to position 1 :in doing the switch
comes on and the machine is ready for operation.
-insert the new blade first between the guides and then
onto the rubber coated pulleys, with the teeth facing as
showed in picture 9;
Before starting any cutting operation, check that all
the protections are complete and in the correct
position.
-put the blade under tension again as described in point
3.1 and reposition the two outer blade guides in slight
contact with the blade, turning the head of the screws
S
Once you have completed all the procedures and
operations described so far, you may start the working
processes.
