supported by the rear part of the guide and the end of
the centering attachment F. Next, after starting up the
machine, button E is gradually released until the miller
is introduced in the wood and the guide is completely
supported, at which time we can begin moving forward.
In making the groove in the frame in order to reach into
the corners begin grooving at an intermediate point on
the frame or crosspiece. Make the groove to one end
then repeat the operation from the same starting point
working towards the other end.
5.1 GROOVES WITH 90° GUIDE (Fig. 11)
This guide is used for making grooves angled at 45° in
the cut-outs of frames or in windows.
5.2 GROOVES WITH STRAIGHT GUIDE
(Fig. 12 and 13)
Used for making straight grooves in the cut-outs of
frames or in windows.
It is possible to groove windows without having to
dismantle the fixed ones. (Fig. 12).
Using the angle, (Fig. 13), grooves can be made on smooth
areas such as the side of the hinges on the door at a
distance which can be adjusted from one side.
6. CHANGING THE GUIDES
Changing the guide (Figs. 2 and 3) is easily carried out
by removing screw B which holds it in place and pulling
it back as shown in (Fig. 3) until it has been removed.
The new guide is inserted in the same way.
On changing the guide, the depth of the groove is
maintained, which means that re-adjustment of the
tool is not usually required.
7. MOUNTING THE REVERSIBLE ANGLE
The reversible angle can be used for both sides of
the machine. For its assembly the 2 screws C must be
removed, (Fig. 4). Insert the reversible angle in the side
openings on the machine and secure it where desired by
supporting it against the body of the machine between
screws C and D. (Fig. 5).
8. CHANGING THE MILLER
Disconnect the machine from the mains
before carrying out this operation.
To change the miller (Fig. 7) block the motor shaft using
key H, unscrew the bolt with the key G and remove
the bit. Insert the new miller until its tip is within 43
± 1mm from the face of the bolt and re-tighten this
using the key.
The millers supplied by VIRUTEX are sharpened at both
ends.
9. CONTROLLING THE DEPTH OF THE GROOVE
Loosen screw K (Fig. 8) until the motor can be moved
by hand. Next turn the eccentric I with the service key
until the required measurement is obtained with the
help of the gauge J. When obtained re-tighten bolt K.
10. JOINTS
The use of VIRUTEX SILICON RUBBER JOINTS is recom-
mended for their high resistance to bad weather and
elasticity under load at temperatures between -60° C
and 200° C.
Types of joints:
..............
1204081 Model FS1 1204082 Model FS2
brown Ø 8 mm. brown Ø 8 mm.
1204181 Model FS1/B 1204182 Model FS2/B
white Ø 8 mm. White Ø 8 mm.
Each type of joint requires the use of the correct bit.
Refer to the table for the different types of bit.
To easily position the joints in the grooves we recommend
the use of SILICON JOINT ROLLERS (ref. 1746158). (Fig. 15)
11. MAINTENANCE OF THE
BRUSHES AND COLLECTOR
Disconnect from the mains before ca-
rrying out any maintenance operations.
Remove the screws L (Fig. 9) that hold the side covers
N and detach them from each other.
Remove the brush-holder P (Fig. 10) with small screw-
driver O, using one of the brush-holder side tabs to
lever it out. Push back the end of spring Q. Keep it in
this position to extract the brush and replace it with a
new genuine Virutex brush. Re-insert the brush-holder,
ensuring that it is firmly positioned in the casing and that
each of the brushes exerts a small amount of pressure
on the collector.
Re-attach the covers N with the corresponding screws,
making sure that no wires get caught in the process.
It is advisable to leave the machine running for 15
minutes once the brushes have been changed.
If the collector burns or juts out, it should be serviced
by a VIRUTEX service technician.
Always keep the lead and plug in good working condition.
