Operation and maintenance manual for P 225
FOREWORD
The machine P 225 is a pendulum bench sawing machine designed for cutting metals.
Operation is manual: after turning on the electrical power supply to the machine and clamping the workpiece in the vice,
the operator starts the blade by pressing the microswitch located on the control lever; he then moves the head downwards
in order to cut the material; after completing the cut, the cutting head returns to position ready for a new cutting cycle.

CHAPTER 1 -- Functional parts of the machine
In order to gain a good understanding of the machine, which will
be described in detail in the chapter ”MACHINE OPERATION”,
we will look at its main units and their respective positions.
1.1 -- Cutting head
The cutting head is the unit that performs the cut and consists of
acastironsectiononwhichthefollowingparts aremounted: the
blade,thebladesupportunits,thedrivetransmissionunitandthe
spindlemotor.Thecuttingheadisfixedtotheturntablebymeans
of a hinge and travels downwards to perform the cut. The
upwards and downward movement of the head is controlled
manually by the operator.
1.2 -- Vice
Theviceistheunitthatholdstheworkpiecesteadyduringcutting;
itconsistsofa vicesupportonwhichtheslidewiththemobilejaw
and the fixed jaw is mounted. The vice support is fixed to the
upper section of the base.
1.3 -- Lubricant/coolant system
The lubricant/coolant system consists of a membrane pump
driven by a cam mechanical system located on the shaft onto
which the blade is flanged.

CHAPTER 2 -- Safety
TheP225hasbeendesignedandconstructedtocomplywithEu-
ropean standards.
It is extremely important that you follow the instructions given in
this chapter, as they are essential for correct use of the
machine.
2.1 -- Intended use of the machine
ThependulumdiscsawingmachineP225isintendedtobeused
exclusively for cutting metal profiles. The machine’s specific
characteristicsmakeitunsuitableforothertypes ofmaterial
or process.
Personneltrainingistheresponsibilityoftheemployer,whomust
inform operators about risks of accident, safety devices, risks
related to noise emission and general safety precautions laid
down by international directives and legislation of the country in
which the machine is used. The operator must be fully aware
of the position and operation of all the machine’s controls.
The instructions, warnings and general safety precautions
describedinthismanualmustbefollowedcompletelybythe
personnel using the machine.
InaccordancewiththeMACHINERYDIRECTIVE98/37/CEEEC
and subsequent supplements and amendments
91/368--93/44--93/68, the following definitions are used:
`”Dangerzone”:anyzonewithinand/oraroundmachineryin
which an exposed person is subject to a risk to his health or
safety.
`”Exposed person”: any person wholly or partially in a
danger zone.
`”Operator”: the person or persons given the task of instal-
ling, operating, adjusting, maintaining, cleaning, repairing or
transporting machinery.
WARNING: The manufacturer is released from all civil and
criminal liability if one or more parts or unitsof the machine
are tampered with and/or replaced without due authorisa-
tion, or if any accessories, tools and expendable materials
are used other than those recommended by the
manufacturer, or if the machine is inserted in a complex sy-
stem or it is used in any way that is different from the inten-
ded use.
2.2 -- General recommendations
LIGHTING
A lack of adequate lighting for the intended type of operation
couldleadtorisksforthesafetyofpersonnel.Forthisreasonthe
userofthemachinemustensurethatsuitablelightingisprovided
for the working environment in order to eliminate any areas of
shadow or irritating glare. (Reference standard ISO 8995--89
”Lighting in working environments”).
CONNECTIONS
On the basis of the machine’s power absorption levels given in
the ”Machine specifications” tables on page 2, check that the
electric and pneumatic power supply lines are able to withstand
themachine’smaximumabsorption levelsandmakeanyneces-
sary changes.
EARTHING SYSTEM

the diagram below.
2.3 -- Recommendations for the operator
Always wear adequate safety glasses.
Do not use the machine without the guards in
position.
Do not place your hands or arms in the cutting
zone while the machine is working or the tool is
still turning.
Do not wear loose--fitting clothing, long sleeves,
gloves of the wrong size, bracelets, chains or
anything else that might get caught in the
machine during operation; tie back long hair.
Always disconnect the machine from the
electrical power supply before carrying out any
maintenance work on the machine or changing
theblade.This also applies tooperationsthatlie
outside the normal use of the machine.

Safety
P 2256
Beforestartingtocut,makesurethatthematerial
is adequately supported on both sides of the
machine.
Work may be carried out on the hydraulic and
pneumaticsystemsonlyafterthepressureinside
them has been released.
Theoperatormustavoid operationsthat areun-
safe or not appropriate for the job being
performed (e.g. removing swarf from the
machine while cutting).
Clearthecuttingareaoftools,implementsandall
otherobjects; keep theworkingareaascleanas
possible.
Before starting the cutting operation, makesure
that the workpiece is held securely by the vice
and that the machine is correctly set up. The
following are examples of how different section
bars can be locked on our sawing machines.
Do not use the machine for cutting workpieces
that exceed the capacity stated on the technical
sheet.
Do not move the machine while it is cutting.
Donotusebladeswithdifferentdimensionsfrom
those declared in the machine specifications.
Whencuttingextremelyshortworkpieces,make
sure that they are not dragged behind the rest
shoulder as this gives rise to a risk of the blade
seizing.
When operating the saw, wear gloves only for
handling material and for adjusting or changing
the blade. Carry out only one operation at a time
and do not fill your hands with more than one
object at the same time. Keep your hands as
clean as possible.
Warning:ifthebladeseizeswhilecutting,imme-
diately press the machine’s emergency stop
button. If the blade does not free, open the vice
slowly,removetheworkpieceandcheck thatthe
blade and the teeth are not broken. If they are,
replace the blade.
Before carrying out any repair work on the
machine,contacttheTechnicalservicecentreor
if necessary its representatives in the countryin
which the machine is used.
