Front and rear cutting flush with the board: (For edging of up to 2
mm thick)
Switch CM1 (Fig. 6) in position 1.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut at
the back, flush with the board. Rear cutting.
If the rear cutting is not flush with the board, see Regulating the excess
at the back of the edging to correct the fault.
2. When board front reaches the blade H (Fig. 21), it moves it forward
and the excess edging at the front is cut flush with the board. Front
cutting.
Front cutting flush with the board and rear cutting with excess: (For
edging of up to 2-mm thick)
Switch CM1 (Fig. 6) in position 2.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut at the
back with a slight delay and an excess is left at the back of the board.
2. When blade H (Fig. 21) of the front cutting unit is reached by the
board, it moves it forward and the excess edging is cut flush with the
board. Front cutting.
Rear cutting flush with the board and front cutting with excess: (For
edging of up to 2 mm thick)
Switch CM1 (Fig. 6) in position 3.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut flush
with the board at the back. Rear cutting.
If the rear cutting is not flush with the board, see regulating the excess
at the back of the edging.
2. When the board presses micro-switch G (Fig. 21) blade H (Fig. 21)
of the front cutting retracts and lets the board pass through, without
cutting the excess at the front.
Front and rear cutting with excess: (For edging of 2-3 mm thick)
Switch CM1 (Fig. 6) in position 4.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut at the
back with a slight delay and an excess is left at the back of the board.
2. When the board presses micro-switch G (Fig. 21), blade H (Fig. 21)
of the front cutting retracts and lets the board pass through, without
cutting the excess at the front.

10. MAINTENANCE AND CLEANING

10.1 CHANGING THE CUTTERS
Before changing the bits, disconnect the machine from
the mains and lock the switch using safety cover K (Fig. 7).
The upper carbide cutter turns in a counterclockwise direction (-) and
the lower, in a clockwise direction (+), as shown on shavings collector
C4 (Fig. 9). Always keep this in mind when changing the carbide cutters.
Changing the upper cutter: Loosen the lever L1 (Fig. 22) and open
the feeder. Remove screws G1 (Fig. 17), take out copying device H1
(Fig. 18) and, using rod S1 (Fig. 19) to lock the spindle of the carbide
cutter, remove screw I1 (Fig. 19) which holds the carbide cutter in place.
Replace the old carbide cutter with a new one and put copying device
set H1 (Fig. 18) back together again, adjusting the height to suit the
finish of the edging with the carbide cutter inserted, as explained in
Adjusting the trimmer.
Changing the lower cutter: Gaining access via rear door F1 (Fig. 13),
loosen knobs B1 (Fig. 11) of the lower trimmer. Acceding now through
front door F3 (Fig.14) bring the head all the way down, with the aid
of knurled knob X (Fig. 9 and 11). To change the carbide cutter, pro-
ceed in the same way as described in the previous section, but bear in
mind that screw I1 (Fig. 19) has a left-hand thread. Once the carbide
cutter has been changed, raise the head fully once again, with the aid
of knurled knob X (Fig. 9), and regulate the copying device set to suit
the finish of the edging with the carbide cutter inserted, as explained
in Adjusting the trimmer.
Sharpening the carbide cutters: The carbide cutters should be shar-
pened, reproducing the original shape axially, without altering the
diameters (Fig. 24). To replace a carbide cutter that has been sharpened,
place as many 0.1-mm 7080013 washers as are necessary on the seat
at the back of the blade to compensate for the axial displacement
caused by the sharpening process.
10.2 CHANGING THE FEEDER BELT
Before changing the belt, disconnect the machine
from the mains and lock the switch using safety cover
K (Fig. 7).
Remove three screws T1 (Fig. 22) and take off the cover.
Loosen jockey wheel U1 (Fig. 23).
Replace belt V1 (Fig. 23) with a new VIRUTEX S.A. original, ensuring
that it engages correctly with the toothed wheels. Tighten the jockey
wheel, applying the necessary amount of pressure for a good dragging
motion and finally replace de cover K (Fig. 7).
10.3 CLEANING AND RECOMMENDATIONS
• To achieve a good clean edging cut, always keep the blades sharp
and free of glue.
• The machine itself should also be kept free of glue build-up and
edging trimmings, to prevent edging jamming.
• The feeder should apply the correct amount of pressure to the surface
of the boards so that these may be conveyed. Excessive pressure leads
to premature deterioration of the feeder belt.
• We recommend keeping the surfaces of gluing roller H2 (Fig. 10)
and of the feeder belt clean and free of glue build-up and particles of
material, in order to achieve a correct board conveying and a perfect
result when gluing.
• To keep the cutters and blades clean, we recommend the use of our
CANTSPRAY (a silicone-free non-stick spray).
• When using short pieces of wood, do not push with your hands. Use
a pushing device.
10.4 CLEANING OF THE TAPE GUIDE
Cleaning the tape guide J4 (Figs. 29 and 29.2)
If you need to clean the tape guide J4 (Fig. 29.2), remove the screw
K4 (Fig. 29) using the service key. First, pull the tape guide J4 (Fig. 29)
until it releases the stops. Then slide to the right the guide J4 (Fig.
29.2) and pull outwards (Fig. 29.2). Clean the guide and proceed to
assemble it in reverse.
To clean the glue residue is recommended our spray cleaner NETSPRAY.
11. BANDING HONEYCOMB PANELS AND 3D AND GLASS
EFFECT TAPES
Honeycomb pattern panels. (Fig. 35)
To work directly with this type of panels is very important to reduce
as much as possible feeder and copiers pressure. To do this proceed
as follows:
- Reduce feeder pressure (see instructions feeder adjustment).
Place the feeder between 1/2 to 1 turn over the requested thickness.
That is, if the board is 19 mm, leaves the feeder between 20 and 21
mm. Keep in mind that the feeding belt must always press the board.
- Reduce trimming unit pressure (see instructions trimming unit setting,
