3. CHARACTERISTICS
UNIVER 330P - 332P - 400P -330IP - 332IP - 400IP – 402P/ IPmitre double saws, produced by
PERTICI S.p.A., are used for cutting:
- plastic profiles, mainly P.V.C. (polyvinyl chloride) and profiles made of light alloys and assimilable
materials.
3.1 Description of machine
The UNIVER 330P - 332P - 400P -330IP - 332IP - 400IP – 402P/IPmitre double saws have two
heads, one fixed and one mobile; the mobile unit is moved by means of a handwheel, with the
micrometric movements being controlled with a device on the side of the mobile unit, for the exact
setting of the desired cutting length.
The cutting length can be read on the millimeter ruler, running the whole length of the machine,
with the reading aided by a magnifying glass.
The two cutting units have adjustable plates that can be turned to make cuts of up to 45°to the
right and to the left, and the blade support heads can be set to 45°to the horizontal axis.
The UNIVER 330P - 332P - 400P -330IP - 332IP - 400IP – 402 P/IPmitre double saws have two
mobile supports, positioned between the two units, providing a particularly useful support surface
for longer cuts.
All the models are available in three versions, based on maximum cutting length.
A special mobile guard closes off the blade completely, guaranteeing operator protection.
In the "P" class models, the blade lowering is controlled by pneumatic actuators.
In the "IP" class models, the blade lowering is controlled by oleopneumatic actuators.
These actuators are controlled by a bimanual device that keeps both hands occupied during the
cutting.
The speed of movement can be set in relation to the material being cut, by means of a variator on
the side of the pneumatic cylinder (from 0 to 6 m/sec) (Fig.A1.8).
The UNIVER 330P - 400P -330IP - 400IP 402P/IPmodels have two horizontal interlock actuators
and two vertical ones, located on the bases or on the mobile supports.
The UNIVER 332P - 332IP models have two vertical interlock actuators located on the bases.
All the interlock cylinders are mounted on jointed supports, and can be set to the cross-section of
the profile of the workpiece to be cut (Fig.A1.9).
A modal switch ST (Fig.A1.3), on the electrical panel, can be used to cut out one of the two
operating units, allowing the machine to be used as a single saw.

08/03/00 17:52 US400IP ING.DOC
4.2 Positioning
The machine must be positioned on a stable floor and fixed to the ground. Be particularly careful
not to position the machine close to areas where there is gas or inflammable substances, as the
sparks and glowing fragments produced and scattered may cause explosions or fires.
Position the machine in a place that is suitable for the work activities and easily served for
connections to:
1) Electrical power supply.
2) Compressed air supply.
3) Cuttings extraction system.
Ensure that the lighting is adequate all around the machine, especially in the cutting area.
Remove the machine from its packaging and check that it has not been damaged during transport.
PERTICI SPA accepts no liability for damage caused during transport. Please check the state of
the pack at the time of purchasing the merchandise.
4.3 Work clearances
The space required to work correctly is a distance of 150 cm all around the machine: Addendum 1
(Fig. A1.4 - A1.6) gives the measurements for the different models and the areas around the
machine in which great care should be taken, where persons or objects may constitute obstacles
or hazards in relation to the work activity.
4.4 Setting to work
Reassembly of feed actuators (Fig. A1.10):
To reduce the size of the package and to prevent breaking the head feed actuators, these devices
are locked apart from their fulcrums. When reassembling, make sure that the locking ring is fitted
properly into the pin housing.
Check the level of the guides and work surfaces, both lengthwise and crosswise, using a spirit
level.
Check the level along the whole length of the machine.
Adjust the 4 support screws (VA M8) on the outsides of the feet to set the machine to level; after
levelling, fix the machine to the floor with the 8 bolts (VB maximum diameter 10 mm), making
reference to the floor anchorage lay-out (Fig. A1.7).
The only installation work that needs to be done is hooking up to the various supply networks, as
described in sections 4.5, 4.6 and 4.7.
Before setting the machine to work, especially if this is the first start-up or if the installation is in a
new location, take note of the precautions and suggestions given in the following pages on the
various hook-up procedures.

MANUALE - ISTRUZIONI - USO
UNIVER 330 ( P / IP)
08/03/00 17:52 US400IP ING.DOC
4.5 Compressed air hook-up
The connection to the line can be made with a rubber or nylon hose and connectors. The supply
hose must have an internal diameter of not less than 10 mm.
The working pressure must be in the region of 6.5 bar/atm.
Hook up the line to the slide valve 1 (Fig. A1.17) mounted on the FRL air treatment unit on the
right leg. When the black coupling sleeve is moved, the pressure on the gauge should read 8
kPascals (8 bar/atm).
If necessary, turn knob 2 on the FRL air treatment unit (Fig. A1.17) to bring the pressure to
around the indicated level.
The function of the filter is to filter the dust and moisture out of the air, as these may be damaging
to the pneumatic actuators (Fig. A1.17).
When the condensate and impurities reach the maximum level in the container, discharge and
empty the container with the breather.
UNIVER 330P - 332P - 400P – 402P
The approximate air consumption, calculated on the maximum work load, is 13.9 l/work cycle.
UNIVER 330IP - 332IP - 400IP – 402IP
The approximate air consumption, calculated on the maximum work load, is 6.7 l/work cycle.
During the first few jobs, check that the pressure reading on the gauge doesn't fall below 6
bar/atm.
ATTENTION: DO NOT CONNECT THE MACHINE WITH A PLANT WHERE A CENTRALISED
LUBRICATING UNIT IS ALREADY PRESENT SINCE A TOO HIGH CONCENTRATION OF
NEBULIZED OIL IN THE AIR COULD DAMAGE THE PROPER WORKING OF THE MACHINE.
4.6 Electrical hook-up
The machine is supplied with the power supply characteristics requested by the customer.
Before connecting to the mains, check the voltage on the machine information plate.
CAUTION:
CHECK THE MACHINE POWER SUPPLY VOLTAGE CAREFULLY
TO AVOID XCAUSING DAMAGE TO THE ELECTRONIC-ELECTROTECHINICAL
COMPONENTS,
THE VOLTAGE MAST COMPLY WITH THE FOLLOWING CONDITION:
Va=Vt +/-10% Vt.
(Where: Va = actual power supply voltage
Vt = machine information plate voltage).
Do not hook up the machine to the electricity mains until it has been properly positioned and fully
assembled.
The user's electricity network must conform to CEI 64-8 standards (CENELEC HD 384, IEC 364-
4/41).

Position (2) = right head cut only enabled
Position (1 and 2) = both heads enabled
- Set the angle of the cutting unit on the horizontal axis by loosening nut (7).
Position the head at the chosen angle and then re-tighten the nut (Fig. A1.11).
Cuts can be made at angles within the range 0 to 45°.
Pull out knob (9) and turn through 90°; rotate the work surface to the desired position, which can
be read exactly on the degree scale on the plate, and lock with knob (8). For angles of: 0, 15,
22.5, 30, 45 degrees, insert the side-pin on the knob (9) to automatically lock in position. As an
additional safety precaution, it is always better to lock knob (8), even if the automatic locking has
already taken place.
- Position the mobile head at the cutting distance, setting the position with the handwheel (3) for
fast movements and the screw (4) for millimetric movements. Use the lens (2) to read the
measurements on the millimeter scale (1) (Fig. A1.11).
After setting to the chosen distance lock the slide on the head with knob (5).
Before using the micrometer setting screw (4), loosen the knob (5) and lock the lever (6). After
positioning, re-lock knob (5).
- Position the profile to be cut on the work surface.
- Lock the workpiece interlock by turning selector SB clockwise.
The pistons work on two pressures: a lower pressure for bringing the workpiece near and a higher
pressure for the final locking.
ALWAYS TAKE CARE WITH THE HANDS DURING THIS OPERATION.
- Press buttons P1 and P2 simultaneously (within 0.4 sec.), to:
- start the blade motors on the selected heads.
- lower the selected cutting unit.
If just one of the buttons is released during the cut, the head will go back to the rest position and,
at the same time, the motors will be disabled.
- Release the profile by turning selector SB anti-clockwise.

the 400 version, the horizontal cylinder has no vertical setting movement.
The vertical interlock actuators can be varied in height, distance and angle in relation to the
workpiece support square, with the following maneuvers:
run the supports (2) along the guides (3) to set the height. Back off the screw (4), rotate the
support and, when positioned, re-tighten the screw (4).
These actuators can be inserted on the work surfaces by fitting the pins (3) into the threaded
housings.
5.6 User safety precautions
- Never remove the safety guards.
- The machine is fitted with guards to protect against the materials and residues thrown up during
the cutting operations. However the operator is advised to use personal safety equipment such as
goggles and gloves, to protect against flying splinters and fragments.
- The operator must take great care when the cutting unit is in movement, thinking and being
aware of all the possible consequences before approaching the more dangerous parts of the
machine (electrical panel - cutting units - interlock actuators) with the hands.
- Always disconnect the machine from the power supply when it is not being used.
- The minimum amount removed in the bar end-cut operations must be no less than 50 mm, to
avoid dragging the workpiece inside the safety guard.
- Never leave the cut workpiece on the work surface; remove it immediately, to avoid leaving loose
pieces of profile lying around on the work surface.

clockwise to decrease (Fig. A1.8).
6.2 Setting the belt tension
To adjust the tension on the motor drive belts loosen lever (1) and press on the motor. When the
belt is set to the correct tension, re-tighten the lever (1) (Fig. A1.12).
6.3 Setting the pull cable tension
If the mobile head doesn't move when handwheel (3) is turned, adjust the tightening device to
reset the cable to the correct tension (Fig. A1.14).
6.4 Setting the pressure
Check that the pressure reading on the gauge is 8 kPascals (8 bar/atm), following the relevant
instructions (Section 4.5).
6.5 Setting the thermal relays
This setting must bee made by our engineers during assembly, with reference to the power input
specifications on the motor information plates.
6.6 Blade lubrication device
When the machine is fitted with this accessory, the container (1) must be filled with a non-grease
lubricant solution.
We advise the use of our product (cod. 25011) which, as well as being innocuous, also has the
correct functional and chemical-physical characteristics, specially formulated for this type of
lubrication. It is also guaranteed ecologically.
The solution is sucked up and sprayed on to the blade. Turn knob (4) to control the flow of fluid
(Fig. A1.15).
IMPORTANT!!!: The air atomization level must not exceed 400 g/cm².
6.7 Fast lowering device
When the machine is fitted with this accessory, the head can be brought up quickly to the
workpiece before the blade starts cutting at the set working speed (Section 6.1). With the head in
the rest state, loosen the nut and turn the cam 1 (Fig. A1.16) so that it pushes against the
pneumatic limit switch lever. The head will perform the complete work stroke at the preset slow
speed. If, however, at the start of the work stroke, the cam is set so that it doesn't immediately
push against the limit switch, the forward speed in that stretch will be fast.

Tests were carried out in line with the specifications in Directive 89/392 Add. I Article 1.7.4, with
measurements made in accordance with ISO 3746 standards.
The test conditions and results are given in the addendum (7).
The operator is advised to use protective equipment, such as good quality soundproof earphones.
To prevent the exposure level from increasing to greater than the test values over time, check the
quality of the blades constantly.
8. MAINTENANCE
The UNIVER 330P - 332P - 400P - 330IP - 332IP - 400IP 402P/IPmitre double saws do not
require any special maintenance operations.
The technical design, materials used and protective paints have been specially developed and
selected to reduce maintenance work.
However, we do recommend a series of operations, divided up into daily and weekly maintenance
operations, aimed at guaranteeing the safety, reliability and efficiency of the machines over time.
8.1 Routine maintenance
The following operations should be carried out on a daily basis, after finishing work:
- Clean mobile head slide-ways.
- Clean the work surfaces.
- With a compressed air jet, blow off any cuttings that have accumulated in the motor protection
grilles.
- Check that there are no cuts or scratches on the mains power supply lead.
- Check the state of wear of the blades.
- Check the lubricant oil level in the filter unit collection container (Fig. A1.17).
- Check the condensate level in the filter unit collection container (Fig. A1.17).
- Check the level of the blade lubricant solution in the container 11 (Fig. A1.15).
8.2 Weekly routine maintenance
- Check the state of wear of the blades.
- Make the following safety checks on the electrical system:
a) cables isolation
b) working order of circuit breaker
c) efficiency of ground connection.
- Check that the various mechanical components are fixed securely.
- Periodically grease and oil all joints prone to seizing.
8.3 Changing the blades
To change the blades, proceed as follows (Fig. A1.12 - A1.13):
- Disconnect from electrical power supply.
- Loosen the self-locking nut (3).
- Withdraw the rod and pull it back, to fully lift up the mobile guard (4) inside the casing.
- Remove the safety shutters (6) and (10) by unscrewing bolts (7) and (11).
- Remove the blade fixed guard (12) by unscrewing the bolts (13).
- Keep the end of the shaft held with the L-wrench (17) and, using wrench (36), back off the bolt
(8). The bolt (8) on the right head has a right-hand thread, and the one on the left head a left-hand
thread.

- Take off the flange (9) and change the blade, then reassemble the complete unit.
IMPORTANT!!!
Check that the flanges are clean in the contact zones and in a perfect state, and check that
the blade is good quality.
If the machine vibrates excessively when first started up, check that the disk is fitted correctly,
proceeding as follows:
- Disconnect form the electrical power supply again.
- Raise up the safety guard.
- Check that the disk is good quality and that it conforms to the required technical specifications
(Section 3).
- Check that it has been properly fitted.

10. MEASUREMENT DISPLAY
The measurement display is an electronic device which allows the length of the profile to be read
on a display mounted on the mobile head. It has a resolution of 1/10 mm and is connected to an
optical ruler which measures the exact position between the fixed head and the mobile head.
The display is switched on with the switching on of the machine. The first operation required
before starting work is to reset the distance to zero.
Move the mobile head towards the fixed one insert the zeroing pin 1 (Fig. A1.18) between the two
stop screws 2 and 3 (Fig. A1.18) on the front part of the carriage and press the key:

The display will show the RESTART measurement that has been set previously by our engineers
during the installation of the machine. On completing this operation, the work can be started.
IMPORTANT: When installing the machine, make a cut at the zeroing distance and check that the
length of the cut profile corresponds to the reading on the display. If there is an error, correct the
position of the mobile head by adjusting the stop screws between the two heads, then repeat the
zeroing operation.
NOTE: Parameters have been set in the display memory that allow it to be adapted to the type of
machine on which it is installed. If these parameters are deleted or altered for accidental reasons,
such as sudden voltage changes or long periods of non-use, the parameters will have to be set
again.
To load the parameters, proceed as follows:
