and fasten it firmly with the two screws T1 (Fig. 13).
The distance between the machine shaft and the edge
of the rail is 102.5 mm.
9.3. Fastening the rail to the part
USING G-CLAMPS: Fasten the rail to the part using
the g-clamps provided with the accessory.
Insert one g-clamp in the slot of the rail at each end, bring
it close to the part and fasten it to the edges (Fig. 14).
USING SUCTION CUPS: The rail can also be fastened
to a part to be worked on with suction cups. This is only
possible when the surface of the material is flat, smooth
and pore-free (Fig. 15).
Mount the suction cups U1 on rail O1, (Fig. 16) by inserting
two screws V1 in the slot. Place the cup on the screws
and fasten it with the washers and wing nuts W1 and
X1, (Fig. 16). We recommend attaching the suction cups
to the rail near each edge of the material. The cup acts
by pressing it down on the surface to which it will be
fastened and moving the central lever to a horizontal
position, as shown in (Fig. 15). The suction cups have
been designed for holding templates during trimming
or sawing work.
If work is carried out non-continuously, with long breaks
in between, the suction of the cups should be checked
before resuming work.
9.4. Working with the machine for parallel cuts
With the machine mounted on its support, fasten the
rail to the material along a previously traced reference
line. Make sure the distance between the centre of the
tool and the edge of the rail is correct as explained
above and begin work (Fig. 13).
As a reference for moving the machine, you can use
the millimetre ruler on the adjustable guide through
the position of the pointer of sight M2 on the fixing
clamp (Fig. 13)
Use the parallel cutting machine more comfortably by
removing one of the side handles Y1 (Fig. 2) from the
trimmer and placing it on the front of the machine
Y1 (Fig. 9).
9.5. Fastening the machine to the material
It is possible to fix the machine to the material to be
trimmed To do this fasten the base of the machine to
the material by placing the two suction cups U1 (Fig.
17) included with the parallel cutting accessory to the
sides of the base of the machine. Insert the suction cup
fixing screws T1 (Fig. 17) in the holes in the base pressing
firmly and turn the fastening lever on each suction cup
to fix it in position.
10. REPAIRING A WORK TOP WITH THE EQUI-
PMENT UF317S (Fig. 18)
With the FRE317S angle trimmer and optional equi-
pment UF317S you can easily cut out damaged work
14
top parts made of mineral materials, replacing them
with new parts.
10.1 Cutting the Work Top
- Attach the cutting tool to the machine, as indicated
in section 5.4 of this manual.
- Turn the motor 45°, as indicated in section 5.3 of
this manual.
- Trace one line on the work top where you want to
cut and another one parallel to it, 102.5 mm (+) or (-)
the radius of the cutting tool you are going to use. The
edge of the UF317S rail must be placed over this second
line to cut the work top.
- Fit angle trimmer FRE317S on equipment UF317S and
fix the rail to the reference line with the two suction pads.
- Adjust the revolving stopper drum on angle trimmer
FRE317S to cut the work top in successive 3 mm deep
cuts, as explained in section 7.2 of this manual.
- Cut the work top, reaching the bottom of back rims.
10.2 Cutting rims
- When you have finished cutting the work top, set the
angle trimmer on the rail in this position by tightening
knob P1 (Fig. 12) and with the tool at the bottom of
the back rim.
- For greater safety, you should also use a suction pad
to fasten the other side of the angle trimmer base to
the work top, as explained in section 9.5 FASTENING
THE MACHINE TO THE PART.
- Slowly cut the rim in an upwards direction with the
assistance of the rising force of the shock absorber.
11. MAINTAINING THE BRUSHES
AND COLLECTOR
Make sure the machine is disconnected
from the power supply before performing
any maintenance work.
The brushes must be replaced when they have a minimum
length of 5 mm. Remove the covers F2 that hold the
brushes G2 (Fig. 20) and replace them with VIRUTEX
originals, making sure they slide smoothly inside the
guides. Remove the brush inside the switch box by
loosening the screws H2 (Fig. 20) that hold the box and
the switch I2 in position to reveal the cover F2 (Fig. 20).
Allow the machine to operate without load for a few
minutes after changing the brushes. Take advantage of
the brush change to check the condition of the collector.
If it appears burnt or has burrs it should be repaired by
the VIRUTEX repair service.

12. LUBRICATION AND CLEANING

The machine is factory delivered fully lubricated and
needs no special care throughout its working life. It is
