llowing procedure should be observed (Fig. 4):
- Remove from the sliding support guide J, screw K which
holds the peg L at one of its ends.
- Position the sliding support S and reassemble to its
previous state.
- Level the sliding support S with respect to the table using
a ruler and by adjusting screw K.
- Proceed in an identical manner with the other sliding
support guide.
- Check the correct sliding of the assembly inside the guides.
4. DESCRIPTION AND START UP
The machine has a safety switch (on-off) A on its right-
hand side (Fig. 5).
This is to safeguard against unexpected start-ups as well as
a for connecting the machine and electrical overload to the
mains. This should be carried out by means of an extension
cable with conductor and earth, using conductors suitable
for a nominal intensity of 16A.
Next to the loader B, (Fig. 5), are the machine remaining
controls (Fig. 6), which consist of an emergency switch
C, on-off switch for the heater F, on-off switch for the
feeder motor D, indicator light E showing on-off status
of the machine and a regulating button G to adjust the
temperature of the heater.
To start up the machine, press the green button R1 (Fig. 5)
to supply voltage to the machine. Pilot E lights up. Then
flick heater switch F and feeder motor switch D to On. If
the machine receives an electrical overload, switch N1 will
be deactivated, cutting off the supply voltage. In order to
re-establish supply, it will first be necessary to flick thermal
switch N1 and repeat the above steps.
If the emergency switch is used, this immediately deac-
tivates all the machine functions, making it necessary to
reset this switch by turning it in the direction f the arrow
and to press the green start-up switch (Fig. 5) in order to
recommence work.
Place a roll of pre-glued tape in loader B (Fig. 5).
Its width must correspond to the thickness of the board to
be edged; we recommend using a tape 3 mm wider than
the board's thickness in order to achieve perfect trimming.
Place the pre-glued tape in the tape guide and adjust the
height of guides I (Fig. 8) to the width of the tape, using
knob J, which raises or lowers guide I, and ensuring that
the tape moves smoothly.
Move the tape manually to the cutting edge and place a
panel on the table, supporting it on the front of control box
U (Fig. 9), and move it over the milled roller to check that
the tape is moving smoothly between the guides.
If no obstacles are observed, move the tape back as far
as the cutting edge using knob K (Fig. 8), ensuring that
the tape is moving correctly against the panel. Close the
feeder and start the machine by pressing the green on-off
button R1 (Fig. 5).
6. TEMPERATURE CONTROL
Before carrying out this operation it is important to take the
precaution of checking that the tape is not in front of the air
outlet from the blower L, (Fig. 9) to prevent it overheating
and thus damaging the pre-glued tape. Start the heater by
moving switch F (Fig. 6) to position 1.
To raise the temperature more quickly, turn the electronic
control G, (Fig. 6) to number 9 on the control scale and
watch the temperature rise quickly.
Once it has reached 300°C turn the knob to point 5 on
the scale and once the needle has stopped moving, the
temperature can be adjusted to the correct level for the
pre-glued tape we are using.
7. STRAIGHT EDGING,
TRIMMING AND FLUSH CUTTING
The machine leaves the factory prepared for this type of
work and the only adjustments needed are for the pre-glued
tape width and the width between the trimming blades for
the panel to be banded (the adjustment for pre-glued tape
width has already been explained in section 5. ASSEMBLY
AND START UP). To adjust the trimming blades and place
them in working position follow the instructions in the
section on 11. ADJUST ING THE BLADES (Fig. 10).
The minimum measurements of panels for this edging work
are the following:
Minimum width 102 mm and 175 mm minimum length.
8. REGULATING EXCESS TAPE AT REAR
When banding, if there is an excess or lack of pre-glued tape
at the rear, the tape can be adjusted moving lever M1 (Fig.
19) slightly to the right or left according to the indication
(+,-) on the machine.
9. CLAMP ASSEMBLY
The machine is equipped with two clamps X, (Fig. 13) fixed
to the extension guide S, which push the panel from the
side of panel on rollers.
It is advisable to place clamp X on the left of the extension
guide S, i.e. at the feeder outlet, to ensure correct trimming.
10. CHANGING THE TRIMMING BLADES
For ease of access to the motorised trimmer open the feeder
by loosening handle H, (Fig. 7).
Remove all of the protection devices which cover the unit
by removing the three screws Y on each side, (Fig. 9).
Remove screws Z which secure the belts unit to pulley W
and remove the pulley, (Fig. 14).
Remove screws A1 which hold the blades in place, (Fig. 15).
Remove the blades.
The blades cut on both sides of the teeth (cuts 1 and 2)
so that the second cut can be used before it is necessary
to change them, by placing the lower blade in the upper
mounting and vice versa, (Fig. 15).
After carrying out any work inside the Tri-
mming Unit always replace the protection
devices in their original positions.
