Virutex RA17 VB Manual De Instrucciones página 8

The machine is equipped with 2 kinds of guide and a reversible
angle that enable the making of grooves in various positions
as explained in the following sections of this manual. It also
has a centering pivot which facilitates the entry of the bit
at the start of the operation.
The machine is also equipped with a suction nozzle which can
be used for connection to our AS182K, AS282K aspirators or
any industrial equivalent via the ASPIRATOR CONNECTION
TUBE No. 9 (Fig. 1).
The power cable can be fed through the brackets on the dust
collection tube to make the machine easier to handle (Fig. 14).
5. TYPES OF MILLING
The grooves can be made in the moveable parts of doors and
windows as well as in the frames, which is recommended for
its simplicity. To control the gradual, centered entry of the
miller in the wood the machine has a centering attachment
F which is activated using button E, (Fig. 6).
To begin a groove button E is pressed to the bottom, and the
machine is placed over the piece to be grooved, 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 main-
tained, 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 ma-
chine. For its assembly the 2 screws C must be removed, (Fig.
8
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 recommended
for their high resistance to bad weather and elasticity under
load at temperatures between -60° C and 200° C.
Types of joints:
..............

brown Ø 8mm.
1204181 Model FS1/B
white Ø 8mm.
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 carrying
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 screwdriver
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
