have removed any dust and resin, reassemble the
cutter-holder around the axis, making sure that
each part fi ts correctly into the linchpin "I" of the
axis and squeezing the screws "H" tightly.
8. CHANGING THE CUTTER-HOLDER
WARNING! Disconnect the machine from the
mains electricity supply before carrying out this
operation.
To change the cutter-holder, undo screws "H"
(Fig. 2) which fasten it to the shaft, remove it, and
replace with another cutter-holder of the right kind,
making sure when you mount it that each part fi ts
correctly in the shaft pin "I", and tightening up
screws "H" securely.
9. OPTIONAL ACCESSORIES.
FITTING AND USING.
FITTING THE 3.5 m COUPLING FOR
EXTERNAL ASPIRATION 6446073
Fit the external aspiration connector "J" (Fig. 3)
supplied with the machine, securing it onto the
head with bolt "K".
Screw the free end of the external aspiration
coupling "L" onto the connector "J" and connect
the other end of the coupling to the Virutex aspirators
AS182K, AS282K or other in dus trial aspirator.
WARNING! The external aspiration connector "J"
(Fig. 3) must never be fi tted onto the machine if
an aspirator is not used, as this would prevent the
unimpeded exit of cut shavings.
USE OF THE RADIUS COPIER 9800150
The radius copier 9800150 permits straight cha-
mfered edges to be made on pieces with exterior
circular curves. Edge rounding or cutting on radius
(R=5, 10 or 15) is also possible using radius cutters
9841005. Moulding profi les are only possible on
completely circular pieces, as these are shaped
in one pass and in one direction only.
WARNING! Disconnect the machine from the mains
electricity supply before fi tting this accessory.
Fitting the copier: Attach the stud "M" (Fig. 4) to
the front part of the guide runner "C" and place the
spacer bushing "N", the spring "O" and the copier
support "Q" onto it, securing the whole with the
washer "R" and the nut "S", ensuring that the lug
"T1" of the copier support is fully home in the slot
"V1" of the guide runner.
Use of the copier: In order to make a shape on a
piece like that of (Fig. 5) with one end of circular
sector, once the cut has been adjusted as explained
in section 6, proceed in three phases as shown
in (Fig. 5):
• Shape the two straight zones (Fig. 5-A), up to the
beginning of circular arc.
• Shape the circular part with the copier (Fig. 5-B).
For this purpose the copier must be adjusted by
placing the machine on the straight part of the piece,
in such a way that the cutter-holder is situated at
the point of departure of the circular arc "E" (Fig. 6);
loosen the nut "W", move the copier forward until
the bearing "X" is resting on the edge of the circular
zone; then tighten down the nut "W" again.
Then shape the entire circular arc, keeping in cons-
tant contact with the edge of bearing "X" (Fig. 6),
until the latter enters the straight zone and the cut
is gradually lost.
• Shaping the rest of the circular arc (Fig. 5-C). To
do this the copier must be changed side, without
changing its position on the support "Q" (Fig. 4).
Back off the nut "S", rotate the copier through 90°
until the lug "T2" is fully seated in the slot "V2";
secure in this position with the nut "S". The rest of
the circular arc is then shaped as shown in (Fig.
7), with the other bearing "Y" serving this time as
a copier on the edge.
UTILIZATION OF THE BASE WITH
GUIDE EX TEN SION 9800050
WARNING! Disconnect the machine from the mains
power supply before fi tting this accessory.
The machine can be used in inverted position
using base accessory 9800050, which permits
the shaping of listels, mouldings, crossbeams,
etc. with greater ease in the workshop.
Fitting the base: Fix the base onto a workbench
using holes "A" (Figs. 8 and 9), or in the centre of
a solid table measuring at least 1,000x600 mm, to
ensure good stability while working.
Attach the machine to the base using bolts "B" and
washers "O" (Fig. 9) supplied with this accessory.
Fit the cutter protector "G" (Figs. 8 and 9), securing
it to the head with knob "D" so as totally to cover
the cutters.
Fitting the guide extension: To fi t the guide ex-
tension, insert the guide columns "F" (Figs. 8 and
10) into the side holes of the guide runner "C",
securing it with bolts "P".
Mains connection: The base is connected to the
mains by its own connection cable.
The shaper machine must always be connected to
the socket "I" (Fig. 8) of the base itself, as this has a
safety system to prevent accidental starting up.
The shaper is started and stopped by switch "K"
(Fig. 8) which is fi tted into the base, so that the
switch of the shaper will have to be left permanently
on with the help of the trigger "J".
WARNING! •Under no circumstances must work
be done with the machine on the base without the
base being attached to the table.
• Never work with the base without fi tting the cutter
pro tec tor.
• Never connect the machine to any socket other
