Safety Elements - Virutex TM72C Mode D'emploi

4.3 TESTING
Before connecting the machine to the mains, check
that the protectors and safety mechanisms are work-
ing properly.
At the same time, make sure that the frequency and
voltage of the mains corresponds to what is indicated
on the machine's name plate. Never connect the cut-off
machine to a power supply system that is not supplied
with good earthing, with the corresponding differential
protection and with a device for guarding against short
circuits caused by overload (e.g. fuses)
In the event of using an extension cord, make sure
that the cross section of the conductors is appropriate
to the length thereof and to the rated current of the
machine itself.
4.4 CHANGING THE VOLTAGE
For Models TM73C and TS73C only. The machines
leave the factory prepared for three-phase 380 V. In
the event of your wishing to change the connections
for a three-phase 220 V, we recommend the change
being made at ONE OF VIRUTEX'S Official Technical
Support Centres.

5. SAFETY ELEMENTS

5.1 START-STOP SWITCH
The cut-off machine has a green button on its handle
to start the machine and, next to it, a red one which
causes the machine to stop immediately.
In the cut-off mode, with the turntable head raised in
its resting position (Fig. 7), press the green button
"H" and use the handle lever, lowering it gently to
make the cut.
ATTENTION!
Do not start to cut until the blade has reached the full
rotation speed.
Do not force the saw. Total or partial lock of the motor
can cause serious breakdowns.
5.2 PROTECTION AGAINST ACCIDENTAL
START-UPS DUE TO POWER FAILURES
The machine has a system which, in the event of a
voltage dip or power failure, cuts out the circuit and
prevents the machine from starting up accidentally.
To start the machine up again, the green start-up
button has to be pressed anew.
5.3 SAW BLADE PROTECTIVE COVER
In its resting position, the saw blade is totally covered
by protective covers and the machine remains fixed
in this position The protective cover "J" covers the
whole saw blade and automatically pulls back when
the turntable swivels ready for cutting (Fig. 8).
ATTENTION! Make sure the saw blade is totally
covered by the protective covers when the machine
is in the resting position. Always keep the protective
covers in good condition.
5.4 TABLE TOP PROTECTIVE COVERS
In the models with a table top, TM72C and TM73C,
8
the machine is equipped with a protector "K" (Fig. 8)
which covers the accessible part of the blade and only
allows the material that is to be cut to enter and pass
through. Similarly in these models, and when the cuts
are being made on the table top, an additional protec-
tive cover should be placed under the table in order to
avoid any possible contact with the disk.
There is also a top "L" ruler which serves as a cutting
guide on the table and as a total saw blade protective
cover in the cut-off mode.
6. ADJUSTMENTS
ATTENTION! Make sure that the machine is un-
plugged from the mains prior to carrying out any kind
of manipulation.
The cut-off machine leaves the factory perfectly ad-
justed. Nevertheless, the following mechanisms are
provided for later adjustments.
6.1 ADJUSTMENT OF THE HINGED HEAD
To adjust the saw blade at 90° as against the machine
body (0° on the indicator situated on the rear hinged
section of the machine) (Fig. 11), use a checking square
between both and proceed as follows:
Loosen handle P and nut Z (Fig. 10) and correct any
possible deviation using the A1 Allen stud.
Similarly, the hinged head can be adjusted at 45° as
against the table top (45° on the rear hinged section of
the machine) in this case by pressing on the B1 stud once
the corresponding nut (Fig. 10) has been loosened.
6.2 ROTATING PLATE ADJUSTEMENT
The machine is provided with an automatic lock at 0°,
15°, 22.5°, 30° and 45° and therefore, rarely requires
resetting at these positions. If necessary, to adjust the
saw blade at 90° can be positioned perpendicular to
the straight edge as follows: Set the machine plate
to 0° (set table indicator S (Fig. 14) to 0° on the plate
scale), place a square between the base ruler and
the saw blade, loosen screws C1 (Fig. 13) which
hold trigger R and move the trigger to correct for
the deviation between the ruler and the cutting disc.
Retighten the screws.
6.3 SETTING THE MAXIMUM CUTTING DEPTH
The cutting depth stop is set by adjusting nut and stud
D1 (Fig. 10) and should be reset whenever the saw
disc is changed or sharpened.
ATTENTION!
-Make sure that the saw does not touch the bottom of
the plate once the lowering stop is set.
-Replace any damaged or broken plate cover.
6.4 SETTING THE SEPARATOR BLADE
For cuts made on top of the upper table (TM72C and
TM73C models only), the machine is equipped with a
separator blade which prevents the cut from closing
on the wood once the saw disc is passed. The blade
position should be set according to the diameter and
condition of the saw disc. To set, do the following:
