Changing The Saw Blade - Virutex RZ270S Manual De Instrucciones

the power supply voltage coincides with what is indicated
on the machine's characteristics plate.
To start up the machine, push button F (Fig. 1) and then operate
its front lock G (Fig. 1). To stop the machine press the button
"X" (Fig. 1) and the switch will return to the off position.
8. CUTTING DOOR BOTTOMS, JAMBS AND SKIRTINGS
After making the necessary depth and height adjustments,
proceed with cutting as follows:
Start up the machine using the button F (Fig. 1), and then
rest it on the skirting or door to be cut and apply pressure
to the handgrip J (Fig. 1) in the lengthways direction, sliding
the machine on the inside of its guides. Once it has arrived
at the stop set previously, slide the machine from left to
right in order to proceed with cutting, doing so by applying
even pressure; do not force the advance of the machine,
which will cause the saw to overheat and produce a faulty
cut. Once finished cutting, gradually reduce the pressure on
the handgrip, and the machine will go back to its starting
position, with the blade inside of its protective cover.
Most doors may be cut without being taken off their hinges.
To do this, the door must be fully opened, as far from the
frame as possible, and held in place. It is recommended
that you cut the door from the inside out, moving away
from the hinges. To avoid splintering veneered or varnished
doors, we recommend making a 2 to 3 mm deep initial cut
on the entrance face of the door, so that the outer layer
may be cleanly cut. This should be followed by a further
cut as described above.
9. CUTTING CORNERS
In order to perform a corner cut, loosen the screws D (Fig.
1) and remove the machine's front guide I (Fig. 1). It is
advisable to leave this operation until the end of the job,
so as to avoid having to adjust the cutting depth each time
a corner is reached.
After this operation, put the machine's front
guide back in place.
10. CUTTING BUILDING MATERIALS
To cut building materials, you must use the diamond disk
7040193 (optional accessory).
Each separate cut must be no deeper than 12 mm.
When using this disk, take special care not to force the
machine forward, thus preventing it from overheating and
so extending its working life recommended.
Cutting building materials produces a large amount of dust,
therefore it is essential that the machine be connected to
an aspirator, as explained in section 12.

11. CHANGING THE SAW BLADE

Unplug the machine from the electrical
outlet before performing any maintenance
or adjustments.
In order to change the saw blade, proceed as follows:
- Loosen the screws H and remove the machine's front
guide I (Fig. 1)
- remove the screws K and remove the front cover L (Fig. 6)
- slide the machine forward until reaching the depth stop,
and then use a screwdriver to apply a slight amount of
pressure on its flange in order to disengage it, thereupon
withdrawing the machine from the base (see zoom in Fig. 6).
- turn the machine upside down, letting it rest on the
handgrip. With the protection of a leather glove, grasp an
end of the saw blade, holding it steady.
Do not perform this operation without using
the protection of a glove.
- loosen the screws M (Fig. 7) that hold down the blade
and replace the worn-out one with a new blade of the
same characteristics.
- for reassembly, perform the preceding operations in
inverse order.
Ensure that the saw disc bearing is comple-
tely free of glue, sawdust, dust, etc, before
mounting the new disc.
12. CONNECTING
In order to connect the machine to an AS182K or AS282K
aspirator or other external aspiration source, fix the aspi-
ration coupling included with the unit to the machine's
aspiration inlet N (Fig. 1).
The chosen external aspiration source may then be hooked
up to the other end of the aspiration coupling.
The brackets A2 (Fig. 1) that are attached to the dust co-
llection tube allow the mains cable to be inserted, making
it easier to manoeuvre.
13. MAINTENANCE OF THE BRUSHES
AND THE COLLECTOR
Disconnect the machine from the mains
before carrying out any maintenance work.
Change the brushes when they are a minimum of 9 mm
long.
Changing the brushes.
Remove cover O by undoing the five screws P that hold
it in place (Fig. 8). Use small screwdriver R to remove
brush holder Q. Put the screwdriver into one of the two
slots and use it as a lever (Fig. 8). Move the end of spring
S back. Holding it in this position, remove used brush T
and replace it with a new original VIRUTEX brush. Put the
brush holder back in place, ensuring that it fits snugly into
the carcass and that each of the brushes press gently on
the collector. The position of the connection terminal of
the brush in the brush holder is shown on the carcass of
