Changing The Cutters - Virutex EB35 Manual De Instrucciones

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
fl ush with the board. Front cutting.
Rear cutting fl ush 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 fl ush with the board at the back. Rear cutting.
If the rear cutting is not fl ush 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

WARNING! Before changing the carbide cutters, 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 fi nish 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, proceed 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 fi nish
of the edging with the carbide cutter inserted, as explained in
Adjusting the trimmer.
Sharpening the carbide cutters: The carbide cutters should
be sharpened, reproducing the original shape axially, without
altering the diameters (Fig. 24). To replace a carbide cutter that
12
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
WARNING! 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 fi nally 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 conve-
ying 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.
11. NOISE LEVELS
The noise of this machine has been measured according to the
UNE-EN ISO3746 standard (1996). The noise measurements
were taken during the trimming and end cutting process and with
a 3-mm pre-glued edge. The noise level in the workplace could
exceed 85dB(A). In this case the necessary precautions against
noise should be taken by the user of the equipment.
12. WARRANTY
All VIRUTEX machines are guaranteed for 12 months from
the date of supply, excluding any damage which is a result of
incorrect use or of natural wear and tear on the machine. All
repairs should be carried out by the offi cial VIRUTEX technical
assistance service.
VIRUTEX reserves the right to modify its products without prior
notice.
