Femi 784 XL Mode D'emploi Et Entretien page 11

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 fi t 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 ..................... 5 Ampere
Nominal input power ......................................... 1200 Watt
Power factor ...............................................................0,96
Nominal speed...................................... 8.000-16.000 rpm
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
is also equipped with a reset function which prevents
the machine from restarting automatically.
The motor of your sawing machine 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.
3 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)
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: 35 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.
