MAKE SURE IT IS COMPLETELY STOPPED, THAT IT CANNOT POSSIBLY MAKE
ANY MOVEMENT AND THAT THE MICROSWITCHES CANNOT BECOME ACTIVE:
DO THIS BY PRESSING ANY OF THE EMERGENCY STOPS.
Make sure there is enough glue in the container for the job to be done.
Operate the resistances On selector. (Q3)
Select the desired working stations.
Insert the strip as far as the first pressure roller.
Adjust the height of the presser to suit the panel to be passed through.
When the heating pot temperature reaches the set point figure, reset the machine
by deactivating the emergency stop, then pressing the green reset button. The
motors may now be switched on by pressing the motor On and chain activated
buttons.
The machine is totally stopped by opening the cabin, operating any of the
emergency stops or turning the main switch to OFF.

3.3 Adjusting presser height:
The height of the presser needs resetting every time the thickness of the board to
be edged changes. This simply involves loosening the levers on the presser fixing pads,
and using the lever to raise or lower the presser to the required value as indicated on
the numerical counter.
3.4 Loading and regulating the band in roll form:
To introduce the roll in the tray carries roll in having felt schedule, to go the first
song by the fixation roller, until it surpasses the center of pressure roller. To adjust the

regulators of height of the song, leaving a small separation so that this it can move
easily. Set the pressure on the feed press using the pressure regulator located on the
door under the heating pot to a pressure of approximately 2,5 bar. To observe that so
much the faucet of the piston of ribbon feeding as that of the cutter is open. Finally to
adjust the pressure of the rollers of pressure by means of their regulators to the wanted
value, for further detail to look at "rollers base. To adjust the pressure of the cutter
according to the thick of the material 2-5 bar.
3.5 Regulating surplus strip:
AT THE FRONT: The amount of surplus may be adjusted via the feed time
regulator timer in the “CONTROL PANEL SCREEN”:
More time: more surplus at the front.
Less time: less surplus at the front.
AT THE BACK: This involves regulating micro S-13.
Moving the micro to the left increases the surplus at the back.
Moving the micro to the right decreases the surplus at the back.

4 WORKING STATIONS:
4.1 PREMILLING STATION PF-12
Composed by two high frequency motors (200 Hz, 12.000 RpM) of 1,5 Kw e/o. to
performance the pre-cleaning of the edge of the panel up to max. 3 mm of depth and 30
mm of height, before the gluing operation. To avoid chip, first motor turns in clock sense
and second against.
4.1.1 Depth regulation of the pre-trimming:
Adjust the readout onto the infeed fence. Be careful before to slack the fixing
pawls.
4.1.2 Adjusting the motor’s premilling:
Take care of one motor commands over the another one, in this case the first
one is the reference one and with the second one it should be taken the final trim, so it
is important the adjustment to follow up the first one.
4.1.3 Adjustment of the first motor:
With the readout at zero. Feed a panel till the working line of the motors.
Advance the motor till the cutting knives contact the panel edge. This means depth = 0.
Second step is to check that the measure of the readout is correct. In doing so, give i.e.
0,5 mm to the readout and check that after running a panel the measure trimmed is 0,5
mm.
4.1.4 Adjustment of the second motor:
As already indicated this second motors has to keep the reference of the first
one. Adjust it by means of the nylon pome till getting a continuous trim from the first one.
In case the perfect perpendicularity between drag chain and cutter is not
achieved, adjust the angle by means of the fixing screws.

5 WORKING STATIONS:
5.1 Glue pot station:
This consists of a roller to glue the band. It must trace 2mm on the board and with
no type of extra regulation must dispense the exact amount of glue on the different sizes
of board, in terms of both width and height.
5.1.1 Dispensing glue:
The thickness of glue on the dispensing roller is regulated by the regulator finger
on the glue flap.
TURNING CLOCKWISE REDUCES THE AMOUNT OF GLUE.
TURNING ANTI-CLOCKWISE INCREASES THE AMOUNT OF GLUE.

5.1.2 Glue level in the tank:
For correct operation, the level must not cover the access door to the inner tank,
because if this happens the gases produced will only be able to escape through the glue
nozzle, and this may cause irregularities in the amount of glue supplied to the edge. On
the other hand, with a very low level the glue would burn, losing its properties and even
forming a layer of encrusted glue that would insulate the glue from the heating
resistances in good conditions, leading to an increase in heating time.

5.1.3 Setting up for correct gluing:
If the glue is not evenly dispensed after adjusting and checking the points above,
for example if there are parts on the top without glue, the first thing to check is that the
panel is being cut square. Then check that the scoring disc has not made too great an
incision in the board. If neither of these is the problem, turn the glue pot fixing screws
and slope the station forwards if there is not enough glue on the top, and backwards if
there is not enough on the bottom. In other words, attempt to get the glue roller and
board parallel to each other.
The best way of doing this is first to take the distance between glue nozzle and
the wall of the presser, then to slightly loosen the glue pot fixing screws and slope the
station as necessary. Then retighten these four screws and measure the distance
between nozzle and presser again to check the inclination that the station has been
given.
5.1.4 Replacing heating resistances:
Once the tray has been withdrawn, to remove the pot first unplug and take out the
thermostat probe, then simply lift until it comes out from the pot swing pin.
GLUE POT M5: From outside it is easier to access the fixing cover for the bottom
and front heating resistances (Nº19,22). Having extracted these and the cable through
plate (nº42), there is full access to the resistances, which are protected by an asbestos
sheet (Nº20,23).
