In particular, using the machine to cut metals is excluded.
Furthermore, in its standard version it cannot be used in places with a risk of explosion.
10. WARNINGSONREMAININGRISKS
Inthistypeofmachine,accesstothebladeisalwayspossible,evenwhenthetelescopicprotectioniscorrectlyadjusted
and locked in height, in relation to the piece to be cut (23 mm above the piece).
It is therefore essential to:
• keep hands as far away as possible from the blade between one passage and the next
• use the passage-end pusher for pieces with a small cross-section
• use special tools (e.g., special pushers, supports for short pieces, etc.)
• completely lower the protection to the level of the table block at the end of work
• in the event of the saw blade breaking, even when operating the stop control the top flywheel is not
braked.Itisthereforenecessarytowaitforittohavestoppedcompletelybeforeopeningthedoorstopreventthe
risk of the belt being thrown.
Keep,moreover, to theinstructionsfor safe usegiven in this manual.
11. CONSTRUCTIVESAFETYSYSTEMS
11.1. Controls
Thecontrolmembersareclearlyvisible,identifiableandeasilyaccessiblebytheoperator,situatedfarfromdangerous
areas.
Theycan onlybeoperated intentionallyby theoperator.
After a period of downtime due to any reason, restarting is only possible after re-establishing the safety conditions
(guards).
Modelswithdirectstartingareequippedwithbrakereleasebutton(withdetent),whileinmodelswithstar-deltastarting,
theswitchingdevicehasanauxiliaryposition(F)(reachedbypressingtheleverinanaxialdirectionbeforeturningit).
This allows the blade to be settled on the wheels by hand when it is fitted on the machine. Release is indicated by
a yellow light close to the controls.
When the emergency stop control is operated (by pressing it), on those models that have it, it stays held in the stop
position and to re-establish operating conditions it is necessary to turn it clockwise to be reset.

11.2. Insufficient or no power supply to the power and control circuits
Cuttingoff,resettingorchangingtheelectricalpowersupplyinanysensecreatesnosituationofdanger.Inparticular,
they do not produce:
• untimelystarting
• anobstacle tostopping if theorder hasalready been given
• an obstacle to manual or automatic stopping of the moving parts
• inefficiencyofthesafetydevices
11.3. Protection against mechanical risks
11.3.1. Stability
The machine is equipped with holes in its foot to be safely fixed to the floor. This has the purpose of only preventing
ittiltingover,butthescrewsmustnotbetightenedfullysincethiswouldcausevibrationduringoperation(itistherefore
advised to use stud bolts and self-locking nuts that have to remain at a distance of 2÷3 mm from the foot).
11.3.2. Risk of breakage during operation
Theentirepathofthebladeinsidethemachineisprotectedwithinterlockedfixedormobileguards,exceptforthesection
strictly involved in sawing, minimizing this risk.
Thepassageofthebladethroughtheworktableblockisprotectedbyaninsertofsoftmaterial(plasticorwood)toprevent
its contact with the metal parts.
11.3.3. Risksduetoroughsurfacesand corners
Alltheprecautions have been taken to prevent any riskofinjury.
11.3.4. Risksofaccessingmovingparts
Flywheels,pulleys andbelts arecompletelyprotected bycowlings obtainedin thebaseand bydoors interlockedby
means of microswitches that prevent starting the machine if they are not closed.
An automatic braking system ensures the machine stops within 10 sec. of operating the control.
11.4. Protectionagainst non-mechanical risks
11.4.1. Fire and explosion
There are sawdust extraction mouths and instructions are provided for their connection in order to obtain efficient
extraction.

12. RECOMMENDATIONSANDADVICEFORSAFEUSE
12.1. Machine isolation procedure
Before doing any maintenance, repair, or other work, the machine must be isolated by disconnecting the line cable
connector or by turning onto position "O" and padlocking the knob of the master switch (on models equipped with
self-braking motor), to isolate the machine with plug connection it is necessary to remove the plug from the socket.
Thismustbedonebythesamepersondoingthework.Ifitisasimplemaintenancejob,thispersonmaybetheoperator.
When the machine is out of order, mark it with a sign.
12.2. General recommendations
• Machinesfor processingwood, giventhe highspeedof thetools andthe speedof execution,are consideredthe
most dangerous ones, therefore it is necessary not to underestimate the risks and to concentrate on the job.
• Thesafetydevicesmustnotbeneutralizedforanyreasonwhatsoever,butonthecontrarytheymustbekeptatpeak
efficiency.
• Avoidusingthemachineifyourpsycho-physicalconditionisnotgood,whichmayimpairyourreflexesorattention.
• Wearclothingsuitedtotheworkrequirements.Donotwearlooseclothing,scarves,bracelets,orotherobjectsthat
could get caught up or be dragged. Protect long hair with a cap.
12.3. At the workplace
• Usetheindividualprotectionfacilities(seeparagraph8) ifworkconditionsrequirethem.
• Keeptheworkareainorder,sufficientlyilluminated;arrangespacestostoretherawandprocessedmaterialsand
tomovearoundthemachine. Likewise,keepthefloorcleanofdustandsawdust.Untidinessis synonymouswith
the risk of accident.
• Make sure the table block insert is in a good state; if the blade passage slot has widened or is chipped, replace
it.

9
12.4. During work
• Always start up extraction even if cutting just a single piece.
• Donot use bladesthat are notsharp enough asthey can produceabnormal vibration.
• In the event of trouble, never act on the machine in movement: operate the stop control and wait for it to stop
completely.
• Nevercutmaterialsthatcancausesparksoroverheatingoftheshavingsandthereforefireorexplosionastheypass
throughtheextractionpipes.
12.5. During maintenance
• Regularmaintenanceofthemechanicalandelectricparts,aswell
asextending the service-lifeof the machineandensuring better
performance,isanimportantsafetyfactor.
• It is absolutely forbidden to set up mechanical members and do
maintenancewithouthavingbeforehandcarriedouttheisolation
proceduregivenabove(seeparagraph12.1).
• Do not climb onto the machine.
• At the end of each operation involving opening or removing
protections,reassemblethemcheckingtheir correctpositioning
andoperationandthatnotoolorforeignbodyhasbeenforgotten
inside.
• ATTENTION:Check the efficiency ofthe guard safety micro
switch monthly; Check that it intervenes before a slot
measuring 3 mm is generated for access to the dangerous
area.Ifthisdoesnothappen,adjustthepositionofthemicro
switch as shown in the figure in a way that its intervention
is anticipated. (only SP-400/500).
• Wearprotectivegloveswhilereplacingtheblade.
• Replacementofmechanical partsmustbedoneexclusively withgenuineparts. Theelectricalcomponentsmust
betheonesindicatedinthelistaccompanyingthewiringdiagram,orwithothershavingthesamesafetyfeatures.
Ifindoubt, consultthemanufacturer.
Non-observance of this point involves losing the manufacturer’s liability on the safety of the machine.
12.6. Advice for use
• Do not tighten the blade too much. Use the tension gauge and tighten according to the width of the blade fitted.
• Neverworkwithbladesthatarenotsharpenoughorthatcutobliquely.Sharpeningandsettingmustbedonecorrectly
andfrequently.
• Alwaysunloosethe blade after use.
• Thethrustwheelofthebladeguidemustneverbeadjustedincontactwiththebackoftheblade,butatadistance
of3÷4 mm. If the bladeis well sharpened andthefeed force regular, itmustnot intervene.
• Onthecontrary,thesidewheelsmustskimoverthebladeastheyhavethespecifictaskofeliminatingitsvibrations
due to the processing.
• Periodicallycheckthestateof theflywheels toverifywhetherthereis anyrocking duetoplayinthe bearings,too
highatemperatureofthebearings,errorsinparallelismoralignment,orabadstateoftheperipheralseal.Thiswill
haveto bereplaced everytime itisworn ordamaged.
• Keepthewheels/lining always clean. Check frequently the condition ofcleaning brush fitted to bottom wheel.
