Adjusting (Fig. 4-5-6-7-8); Use - Femi 785 XL Gebrauchsanleitung Und Wartung

2.4 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 fitted upstream of the mains to protect all the
conductors from short circuits and overloads.
This protective device should be selected according to the
electrical features of the machine stated on the motor.
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 D (Fig. 7) is also equipped with a
reset function which prevents the machine from restarting
automatically.
The motor of your BENCHTOP BAND SAW 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)
Rotate the handwheel E clockwise until the indicator F on
the machine body is aligned with the position "MAX" on
the plate.
ATTENTION: Tensioning the blade over the MAX
reference notch on the plate may cause the blade
come out and damage to the machine; please
follow this instruction carefully.
3.2 BAR STOP BENCHTOP BAND SAW (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 nut 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)
To performe a cut at 45, slacken the two knobs M and rotate
the body to the left until it rest on stop N, whose position was
calibrated during the fi nal inspection.
For all the other intermediate angles, match the indicator
of the swivel supporto with the respective position on the
plate O.
3.4 CUTTING SPEED (Fig. 7)
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.
3.5 SLIDING BLADE GUIDE (Fig. 8)
The sliding blades guide P with integrated protection fi tted 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.

Slacken the knobs Q and slide the blades 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 R using a 10 mm.
wrenches key.

USE

4.1 RUNNING IN THE BLADE
ATTENTION: If the correct running in procedure
is not performed, the bladès cutting precision
may be irreparably compromised.
To obtain the best performance, the bi-metal blades fi tted on
your sawing 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 Ø40-50 mm (BENCHTOP
BAND SAW) / Ø70-80 mm (WHEEL-MOUNTED BAND
SAW), using a very slight 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) Ø50 mm
(BENCHTOP BAND SAW) / Ø80 mm (WHEEL-MOUNTED
BAND SAW), should be done in about 4/5 minutes.
After running-in, the same piece may easily be cut in about
3 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.
4.2 WORKING (Fig. 7)
Turn the main switch D to position 1 : in doing the switch
comes on and the machine is ready for operation.
ATTENTION: Before starting any cutting
operation, check that all the protections are
complete and in the correct position.
