GENERALWARNINGS
This machine was design and built using the state of the art techniques, and with respect of the machine tools European
Laws.
Notwithstanding what above, it is implicit that working underestimating or forgiving the dangers which this kind of ma-
chinecangenerate,theoperatorcouldcauseaseriousinjurytohim/herself.
Therefore,the operatorshould carefullyreadthe entireinstruction manual,andrespect strictlywhatinitprescribed.
Inparticular, pleasepayattentionto thefollowingsuggestions:
1. Keepalwaysyourworkingareaclean.
2. Avoid to keep in your working area pieces of material, chips, cans, or other things which could reduce the possi-
bilityofmovementfortheoperatororevengeneraterisksofinjury.
3. Be always cautious using the machine, because, even if it is protected in every dangerous spot, it can be a dan-
gerous equipment,andthusithastobeusebeingparticularlycareful andaware.
4. Give immediately notice to your supervisor if the machine needs to be maintained or serviced, even if the prob-
lemiscausedby inexperience.Anincorrectuseofthemachinecanbedangerousandcancauseinjuries.

2.2.BLADESPEED
Theblade speed is controlledbyan AC motor and avariablefrequencydrive, whichallowtoregulatethebladespeedwithin
arangeof 0- 100 m/1’. Inthiswaythemachine cancutboth hardsteelsand aluminum.Adigitalreader constantlyshowsthe
bladespeed .
Theblade speedcanbe adjusted :
• inautomaticcycleduringtheediting;
• inmanual usingarotarypotentiometer mountedonthe controlpanel.
2.3.WORKINGSURFACE
The material that has to be cut layson a roller waythat covers the entire stroke of the machine. The distance between the roll-
ersis studied to avoidthatshortpiecescan fall.
2.4.INDEXING
The material is fed byan index with hydraulic vises, which clamp the piece and move it under the blade. The index moves
on round chrome guides located underneath the roller table, and it is controlledbya tempered steelprecision ball screw. The
index has two speeds : fast to move and slow to precisely position the piece. A rotary encoder (with a precisionof a tenth of
amillimeter)controlstheposition oftheindex.

5.6.WORKABLEMATERIALS
This machine can cut only metallic bars, pipes and tubing. Every other use will is considered inappropriate use of the ma-
chine.
5.7.WORK AREA
This machine has to work in industrial environment. It is design to make mechanical machining under human control, but
theoperator presenceis not requiredcontinuously.
Itisrecommendedtokeep clean andfree of interference the areacloseto themachine.
Thismachine usea mixtureof oil andwateras coolantliquid. Thus,theworkingareacould beslipperyanddirty.
THIS AREA MUST BE MARKED BY AN APPROPRIATE SIGNAL.
5.8.WORKPLACE
Themachinehas oneworkplace in frontofthecontrol panel.

Each work place must be easy to reach when necessary, without interference, even temporary. The machine can work
automaticallywithout operator, who must be present duringthe manual operations ofloading andunloading, and controlthe
controlpanel operations.

No specific illumination is required, but the work place must be well illuminated to respect the requirements set bypresent
safetyrules.
Onlyauthorized people andmaintenance personnelshouldbe allowedtoreach thesawwork place.
Theoperator mustbe equipped withpersonal protectioninstruments,like glovesand safetyglasses.
5.9. COMMANDMODES,STOP,EMERGENCYSTOPANDOUTOFSERVICE.
5.9.1Commandmodes
Thesaw canbe controlled intwo differentways:
1. Automaticmode, allautomaticcommandsareenable.
2. Manualmode, all thecommands are switchedto thecontrolpanel push-buttonandswitches.

5.9.1.2.Emergencystop
Theemergencystop stops themachineremovingtension fromthecontrol circuit.
5.9.1.3.Outofservice
The saw can be turned out of service removing tension from the control circuit, switching off the main disconnect switch lo-
cated on the front face of the enclosure. A signal saying “Out of service” must be placed on the machine, and it is operator’s
dutyto verifythat themachinecannot generatedangersituations.
5.9.1.4.Safetyprecautions
Themachine cannotgeneratedangersituationwhen itiscompletelywithoutelectric orhydraulicpower.
Concerning the electrical power, the machine mustbe completelydisconnected from electrical sources,turning of theelectri-
cal socket on the building electrical panel. The machine cannot be considered completely safe if the only main disconnect

6.1.1.Baseframe
The machine frame is welded and machined. The material used is Fe 37. In the weldment there are two reservoirs, one for
thecoolant liquid,and the secondfor thehydraulicoil.
The frame is machined to avoid corners or abrasive points that could be dangerous. It is painted with two layers of paint, the
firstof whichprevent corrosion.
Itis machinedtobe assembledwith other machinecomponents.

idler wheel shaft. An hydraulic cylinder, that works on the slide, keeps the band in tension. A limit switch protects the ma-
chineturningimmediatelyoffthemachineifthebladebrakes.
6.2.6Banddriveassembly
Theband is powered byanAC motorwhich automaticallyregulatesthe rotation speed.Usingtwo pulleysandthreeV-belts,
the motor makes the speed reducer turning. On the other end of the reducer there is the drive wheel, that is fastened to the re-
ducerusingacolletlocking.

6.2.9Cuttingservo-control
The Cutting servo-control automaticallycontrols the saw feed rate. A servovalve has an extension which touches the blade
back,and registersthe effortstocut thepiece. Theservovalvemodifies thefeedrate for:
• shapeof piece
• materialhardness
• bladewear condition
Theoperator, readingontheknob, isallowedto changethepreferredfeed rate.

It is in the machineframe, and it has a maximum and a minimum level indicators, and asuction filter. Onthe left sideof the
infeedrollertablethereisaplugwhichallowstorefillthereservoir.Thehydraulicsystemhas2 filters:
• a 250micron 45litres suction filter
• a 60micron45 litersoutflow filter
These two filters have to be removed when changing the oil for the first time (after 500 working hours), washed using tri-
chloroethylene anddriedblowingair.
6.3.3Solenoidvalves
Thesolenoid valvesare mounted onblocks, andthecontrol thehydraulic movements.
