Adjusting (Fig. 4-5-6-7-8) - Femi 780 XL Mode D'emploi Et Entretien

In respect of ergonomic criteria during cutting operations,
the work bench must be positioned at such a height that
the clamp level is between 90 and 95 cm from the ground
(see Fig. 3).
ATTENTION: Make sure that the machine is placed
in a working area with suitable environmental
conditions and lighting.
The general conditions of the working environment
are of fun damental importance for accident
prevention.
2.5 ELECTRICAL CONNECTIONS
Check that the mains to which the machine is connected is
earthed in accordance with current safety regulations and
that the power point is in good condition.
Remember that there should be a magnetothermic protective
device fit ted upstream of the mains to protect all the
conductors from short cir cuits and overloads.
This protective device should be selected according to the
electrical features of the machine listed below:
Nominal voltage ...................................................230 Volt ~
Nominal frequency ............................................ 50/60 Hertz
Max programmed absorbed value .................... 2,5 Ampere
Nominal input power .............................780 XL - 850 Watts
..................................................782 XL/783 XL - 950 Watts
Power factor ..................................................................0,92
Nominal speed .................................. 10.000-23.000 Giri/m'
Insulation ................................................................Classe F
Type of service .......................... intermittent S4-20 % 5 min
In case of power failure in mains, while you wait for
power to be restored there is no danger hazard may
arise: in fact, the electronic governor O or main switch
D is also equipped with a reset function which prevents
the machine from restarting automatically.
The motor of your sawing machine (electronic version)
is equipped with a protective heat circuit breaker which
interrupts the power supply when the temperature of the
coils rises too high.
When the power supply is interrupted, wait for normal
reset.

ADJUSTING (Fig. 4-5-6-7-8)

3.1 TENSION OF THE BLADE (Fig. 4)
Turn the handwheel B in a clockwise direction until it locks.
ATTENTION: If the tension is too high, the blade
tends to escape from the guide. In this case,
slacken the blade tension by turning of one/two
turns the handwheel B in a anti clockwise direc-
tion.
3.2 BAR STOP (Fig. 5)
Use the bar stop supplied if you have to do several cuts on
pieces of the same length.
In this way you do not have to repeat the same measurement
each time.
Screw rod E into the hole of the base and fasten it with nuts F.
Slacken the handwheel G and place the stop L at the correct
distance from the blade. Tighten handwheel G again.
3.3 CUTTING ANGLE (Fig. 6)
The band saw can cut at an angle varying from 0 to 45
degrees: it is suffi cient to slacken the handle I and turn
the swiwel support J towards the respective limit stops H
and K.
For all intermediate angles, turn the swiwel support J until
the mark M on the support matches the corresponding
position on the plate.
Then lock the rotating support J again.
3.4 CUTTING SPEED (Fig. 7)
Two speed version
Depending on the type of material and its section (see
CUTTING TABLE) you can choose two different cutting speed
60 or 80 m/min. by means of the switch N.
Electronic version
Your sawing machine is equipped with CESC (Constant
Electronic Speed Control), which allows gradual and
continuous variation of the cutting speed, adapting it to the
type and dimension of the material to be cut (see cutting
table).
To select the most suitable speed, use the speed control knob
O to increase or decrease the speed as you require.
Example:
Stainless Steel: 30 m/min.
Common Steel: 40-60 m/min.
Allum. Alloy: 80 m/min.
Pipes/sections: 70-80 m/min.
3.5 SLIDING BLADE GUIDE (Fig. 8)
The sliding blade guide P with integrated protection fi tted on
your saw ing 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.
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 fi gure.
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.
3.6 BEARINGS BLADE GUIDE (Fig. 9)
The blade-guide 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 completly locked.
In order to approach or remove the eccentric blade-guide,
gently turn the head of the screws S using a 10 mm.
wrenches key.
4 USE
4.1 RUNNING IN THE BLADE
ATTENTION: If the correct running in procedure
is not performed, the blade's cutting precision
may be irreparably compromised.
To obtain the best performance, the bi-metal blades fi tted on
your saw ing machine must be run in for a short period. For
this reason the fi rst two or three cuts should be done where
possible on a solid piece D.40-50 mm, using a very slight
position 1
position 2-3-4
position 6
position 5-6
