Virutex EB25 Manual De Instrucciones página 10

Using knob M raise the upper blade holder until the panel
can pass beneath it, (Fig. 10).
Insert the panel between the four supporting rollers N, until
it touches the shoe P on the blade holder.
Check that the lower blade holder rollers raise the panel
slightly above guides R, (Fig. 9). Using knob M lower the
upper blade holder until the panel is sitting on the guides
R. The trimmer is now ready for work.
12. ADJUSTMENT OF THE EXTENSION GUIDE
1. Loosen knobs T, (Fig. 1) and place the machine extension
guide S, (Fig. 13), in such a position that the panel is well
supported on guides R, (Fig. 9) touching the front U (Fig.
9) on the control box.
2. Push the wood forward until it is picked up by the feeder,
at which point we can let it go, as it is guided with sufficient
pressure to stick the pre-glued tape to the edge.
3. As the panel moves through the machine, it goes through
the motorised trimmer where the excess tape is trimmed
off from both sides of the panel.
4. After this process the panel is moved on and as it leaves
the feeder it is pressed against a blade V, (Fig. 12), which
cuts off any remaining excess pre-glued tape.
5. The final product is a panel on which the pre-glued tape
has all been trimmed and the edges are flush cut.
13. CHANGING THE TRIMMER BELTS
Remove the protective devices which cover the unit by
removing the three screws Y from each side, (Fig. 9).
Remove the used toothed belt and replace it with a new
VIRUTEX original spare lining it up correctly with the teeth
on the pulley without forcing it, (Fig. 14).
14. CHANGING THE TRIMMER BRUSHES
Disconneet the connection cable of the motorised trimmer.
Remove the motorised trimmer from its housing in the
machine, loosening screws X1 (Fig. 14).
Remove screws B1 from the protector D1, removing the
latter from its housing and cover (Fig. 16).
Raise springs C1 (Fig. 16 bis) which hold the brushes in
place and replace the brushes with VIRUTEX original spares,
ensuring that they move smoothly inside the guides.
Replace the cap D1.
It is recommendable to leave the trimmer running for 10
minutes without working to shape the brushes better.
If any roughness or damage is observed on the collector, we
recommend you have it repaired at a VIRUTEX service point.
Never use sandpaper for this operation.
15. ADJUSTMENT OF THE FEEDER
Loosen the handles F1 and G1, (Fig. 17 and 7).
Position the feeder index to the measurement correspon-
ding to the thickness of the panel by turning the wheel
H1, (Fig. 7).
Tighten the handles F1 and G1, (Fig. 17 and 7).
Open the feeder using handle H, (Fig. 7) in order to see
the height of the trimmer blades, and adjust the height
10
if necessary, (section 11. ADJUSTMENT OF THE TRIMMING
BLADES). The lamp E, (Fig. 6) on the indicator panel when
opening the feeder.
Once the trimmer blades have been adjusted close the
feeder using handle H, (Fig. 7), leaving a slight angle with
respect to the rollers on which the panel moves. Thus, when
the feeder is operating the panel will always be pressed
against the corresponding rollers when it is being pulled
through the machine.
Press safety switch R1, (Fig. 5), to connect the current to
the machine.
16. CHANGING THE BELT
Remove the three screws J1, (Fig. 11) and take off the
cover. Loosen the tensor pulley K1 and slacken the belt
if necessary, (Fig. 18). Replace the belt L1 with another
original VIRUTEX, checking that it correctly meshes with
all the toothed pulleys.
Tension the belt by sliding the tensor pulley in order that
it gives a good drag when in service.
17. NOISE LEVEL
The measured noise level values are emission levels and
do not necessarily reflect a safe working level. Factors
influencing the real noise exposure level experienced by the
operator include the exposure duration, characteristics of
the location, other sources of emission, such as the number
of machines installed, etc.
The noise from this machine has been measured according
to regulation UNE-EN ISO3746 (1996). Noise measurements
were taken during the trimming and end cutting process,
with a 1 mm edge. The noise level at the work station may
exceed 85 dB(A). In this case, the machine operator should
take protective measures against noise.
Other factors that reduce noise exposure are:
• Selecting the correct tool.
• Adequate tool and machine maintenance.
• The use of appropriate hearing protection systems.
18. RECOMMENDATIONS
For any work involving handling of the machine, disconnect
from the mains. Maintain the supply cable and plug in good
condition. In order to obtain a good cut of the tape we
should always work with sharp, glue-free blades.
The machine must also be kept clean and free of glue
and tape cuttings in order to avoid the pre-glued tape
becoming jammed.
The pressure the feeder exerts on the surface of the panels
through the machine as excess pressure will cause increased
wear on the feed belt.
It is also recommended that the surface of the belt be kept
clean and free of glue and foreign bodies in order to obtain
perfect pulling of the panels.
For cleaning the blades, we recommend use of our CANTS-
PRAY (nonadherent silicone-free spray).
