11. MAINTENANCE AND CLEANING
Ensure that the machine is disconnected
from the mains before carrying out any of
these operations.
11.1 CHANGING THE SAW BLADE
Loosen the knobs M (Fig. 1) and raise the table to its maximum
position, remove the main divider knife and the side guard
cover through the screws Z8 (Fig. 32 and 33).
Then, press button O and slowly turn the saw until it is locked
(Fig. 1). Next, release screw P (Fig. 12) clockwise using the
service key supplied. Once the saw blade is released move it
upwards and then remove it down through the side of the
head of the machine, avoiding the protector.
Do the reverse of this operation to insert the new saw blade,
positioning the arrow on the blade in the same direction
as that on the tilting protector, checking that the element
seatings are perfectly clean and ensuring that the external
securing disc laser fits perfectly into the recess at the end
of the shaft.
Once the disc has been mounted, move it gently until the
locking button has been released.
- Ensure that the replacement saw blade
has the same diameter than the old one.
- Do not use damaged or deformed saw blades.
- Select the correct saw blade for the type
of material to be cut.
- Only use the saw blades which comply with
the conditions contained in this manual and
in every case ensure that the body of the saw
blade is thinner than the thickness of the
riving knife and at the same time the teeth
are wider than this thickness.
11.2 CHANGING THE BELTS
To change the belts on the machine proceed as follows:
- Release screws S (Fig. 13) and remove the transmission cap.
- Remove the broken or worn belts and replace them with
new ones, remembering that the inner belt must always be
fitted first, so that the rear pulley equipment will be fitted
on the tilting arm on the machine (Fig. 13). Next, the outer
belt is fitted, ensuring that it is correctly engaged in the
pulleys, and using the service key also used for changing
the saw, slowly turn the axle while pushing the transmission
cap towards the tilting arm. It is important to ensure that
centering pivots T are gently inserted into their positions.
NOTE: The operation of assembling the transmission cap with
the tilting arm must be carried out manually without ever
hitting or forcing any of the parts, as in this circumstance
the machine cannot be guaranteed to work correctly.
11.4 MOTOR BRAKE
The machine is equipped with a mechanical, centrifugal
brake which ensures that the time between release of the
switch pushbutton and complete stopping of the saw blade
is less than ten seconds.
For your safety, and owing to the complexity of the operation,
we recommend that, if due to wear of the brake linings
the time to stop the saw blade is observed to exceed the
above mentioned value, the machine should be taken to
an Official VIRUTEX technical service centre for changing
of the brake linings.
11.5 REPLACING THE BATTERIES
FOR THE LASER GUIDE
Once the laser guide batteries are dead, replace them with
new ones in the following way: loosen the screws R1 (Fig.
23), remove the battery compartment cover, remove the
dead batteries and replace them with new ones. Proceed in
reverse to reassemble, taking into account that the positive
pole of the batteries should be on the outer side of the
compartment (Fig. 35).
Use LR44 type batteries only.
Do not use rechargeable batteries.
11.6 LUBRICATION AND CLEANING
The machine has been delivered fully lubricated from the
factory and should not require any special care during its
working life. It is sufficient to periodically clean and grease
the mechanical articulations with oil.
It is important to always carefully clean the machine after
each use using compressed air.
Keep the electrical cable in perfect condition.
12. NOISE AND VIBRATION LEVEL
The noise and vibration levels of this device have been
measured in accordance with European standard EN 61029-1
and EN 61029-2-11 (TM33W) and EN 61029-2-9 (TS33W)
and serve as a basis for comparison 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 exposure 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 of the work cycle or the manner in which
the electrical device is used.
Therefore, it is necessary to establish safety measures to
protect the user from the effects of vibrations, such as
maintaining both the device and its tools in perfect con-
dition and organising the duration of work cycles (such as
