CUTTING CAPACITY (Fig. 10)
The table below specifi es the cutting capacity at 0 and 45
degrees which may be obtained in normal conditions of use
described in this manual and without placing any other object
between the jaws of the clamp.
pressure on the blade, and gradually increasing pressure
in subsequent cuts. To gauge the correct pressure in normal
operating conditions defi ned by this manual (see cutting
table), consider for example that the fi rst cut on solid steel
(eg. C40) D.50 mm should be done in about 4 minutes.
After running-in, the same piece may easily be cut in about
2 minutes. If the running-in process is done correctly, the
fi nish and precision of the cut will be of better quality and
the blade will last longer.

WORKING (Fig. 7)
Two speed version
Push the green button
“1”
of the main switch
D
to anable
machine oper ation.
Electronic version
Turn the main switch
D
to position 1: in doing the switch
comes on and machine is ready for operation.
ATTENTION: Before starting any cutting
operation, check that all the protections are
complete and in the correct position.
Once you have completed all the procedures and operations
described so far, you may start the working processes.
To perform the cut, move to the front of the machine and grip
the hand grip with your right hand.
ATTENTION: 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 fi nger 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.
Now begin to apply gradual pressure on the part and
complete the cut.
ATTENTION: 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
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 defi ned by the insulation class,
to prevent damage to the motor.
In this case, release the button A and wait for automatic reset
which usually takes place after a few minutes.
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 can
not absorb an amount of current greater than the set one,
expressed by the maximum value of absorption (see 2.5).
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.

REPLACING THE BLADE (Fig. 9)
CAUTION: When you perform this operation,
always wear protective gloves to avoid contact
