7. ADJUSTING THE BIT HEIGHT
Disconnect the machine from the mains
before making any adjustments to the
machine
.
Protector C does not need to be removed in order to
adjust the bit height (Fig. 4).
Loosen screw D (Fig. 4) using key E (Fig. 4) until the mo-
tor body F can move. Turn the eccentric G (Fig. 4) using
the same key E (Fig. 4) until the edge of the cutter bit
with radius H (Fig. 5) is level with the base I (Fig. 5) and
firmly tighten screw D (Fig. 4) in this position.
8. ADJUSTING THE FEELER
The machine includes feeler C (Figs. 5, 6 and 7) which acts
as a support guide and determines the depth of same.
We advise routing the desired radius in two or three
cuts in order to prevent vibrations and marks on the
finished radius. The feeler must be adjusted for each cut.
First cut:
To adjust the feeler for the first cut, loosen screws J (Fig.
6) with spanner E (Fig. 6) and move the feeler forward
until it can go no further.
Last cut:
To adjust the feeler for the last cut, loosen screws J (Fig.
6) and move the feeler until the edge of bit H (Fig. 6) is
level with the feeler. Since the bit is spiral, you will have
to turn it 360° in order to check this (Fig. 6).
To ensure that the edge and the feeler are accurately
aligned, use support ruler K (Fig. 6). Once the correct
position of the bit has been established, tighten screws
J again (Fig. 6).
Intermediate cut:
Should you wish to make the radius in 3 cuts, place the
feeler in an intermediate position, between the two
positions explained above.
Before routing radius (Fig. 7) on the work top, do a test
trim to check that the height of the cutter bit and the
position of the feeler are correctly set.
9. CHANGING THE BIT
Make sure you place the chuck collet in
the correct position, otherwise vibrations
may occur or the part itself my come
loose (Fig. 12).
Disconnect the machine from the mains
before performing this operation.
To change the cutter bit, first remove the feeler C (Fig.
6), removing the screws J (Fig. 6). Block the motor shaft
using key L, unscrew the nut with the key M (Fig. 8),
remove the worn bit and insert a new one. Hold it in
position by tightening the nut with key M and let it slide
until the edge rests on the support surface.
Adjust the height of the bit, as explained in the cor-
responding section (Fig. 5).
10. MAINTENANCE. CARBON
BRUSHES AND COMMUTATOR
Disconnect the machine from the
power supply before any maintenance
operation.
Remove the screws N (Fig. 9) that hold the side covers
O (Fig. 9) and separate them. Remove the brush-holder
P (Fig. 10) with small screwdriver Q, using one of the
brush-holder side tabs to lever it out. Push back the end
of spring R. Keep it in this position to remove the brush
and replace it with a new genuine Virutex brush. Reinsert
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 O 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 after the
brushes have been changed.
If the collector burns or juts out, it should be serviced
by a VIRUTEX technical service. Always keep the cable
and plug in good service condition.
11. LUBRICATION AND CLEANING
The machine comes fully lubricated from the factory and
does not require special care during its working life. It is
important to always clean the machine carefully after
use with a dry air blower.
Keep the power cable in perfect working condition.
12. NOISE LEVEL AND VIBRATIONS
The noise and vibration levels of this device have been
measured in accordance with European standard EN
60745-2-17 and EN 60745-1 and serve as a basis for com-
parison with other machines with similar applications.
The indicated vibration level has been determined for
the device’s main applications and may be used as an
initial value for evaluating the risk presented by expo-
sure to vibrations. However, vibrations may reach levels
that are quite different from the declared value under
other application conditions, with other tools or with
insufficient maintenance of the electrical device or its
accessories, reaching a much higher value as a result
