Always remove theplug fromthemainspowerbefore
movingthemachine.
11.ELECTRICALCONNECTION
Connect the mainspower cabletothe plug on the electrical
panel.

Tostartup the saw,press the green ONkeyon the RCCB
switchand an orange led illuminates(RCCBprotection on).
RESIDUALCURRENTCIRCUITBREAKERTEST:
Press the black key TESTon the RCCB; the switch
disconnects and the orange led turnsoff.
After performing the TEST,press the ONkeyagaintoactivate
theRCCB.
-CarryouttheRCCB TESTbeforeeachmachinestart-
up.
Then startthe sawbysupportofthe switchon the handle,
comprising twobuttons: green for start, red for stop.

-All powersupplyinstallationsmust complywith
CEI64-8standards(harmoniseddocumentCENELEC
HD384).
12.MACHINESTART-UP
Before connecting the machine tothe power supply:
1-Ensure thatthe tankcontainssufficientcooling water.
2-Connect the power supplycabletothe electricpanelplug.
3-Turn on the concretemixer using the switchlocated on the
electriccontrolpanel(ref. 7,fig.1) comprising twobuttons: the
green one switcheson the machine,whilethe red one switches
itoff. The switchhasminimumvoltage protection:after apower
failure or accidentalpower loss, pushthe green startbutton to
startthe machine up again.
4-Check thatthe direction of blade rotation correspondstothat
indicated bythe arrowon the blade guard.
Open the valveand ensure sufficientflowofcooling water to
the diamond blade.
5-Never drycutmaterialor cutwhen cooling water levels
arelow.
6-If all isinorder,proceed withcutting.
13.EMERGENCYSTOP
-Incase ofanemergency,stop themachineby
pressing theredstop button (extended),thendisconnect
theplug fromthepowersupplysocket.
-Themotorisprotectedagainstautomaticre-start
afterinterruptionsduetopowerfailure.Toresume
operation,whenpowerisre-connected,press thegreen
switchontheoverloadcutoutdevice.
14.BLADEINSTALLATION
Alwaysremovetheplug fromthemainspower.
The diamond blade ismade ofmaterialthatmaybe damaged
when subject tohigh temperatures, and therefore must be
cooled during the workphases.
Toreplacethe blade,proceed asfollows:
1.Block axialmovementofthe cutting head bymeansofthe
handwheels(ref.11fig.1).
2.Stop the blade rotation fitting the shaftblocking pin(ref. 1fig.
5) inthe holeofthe beltcover (ref. 2fig.5) rotating the blade
till the pinhasentered the holeinthe shaft.
Verifythattheblade doesn’tturn,otherwiserepeatthe
operation again.
3.Disassemblethe frontguard.
4.Loosen the locknutbyrotating clockwise(left thread),
using a19 mm wrench.
5.Movethe cutting head forward slightlyand incline to
removethe blade fromits seat.
6.Ensure thatthere are no foreign objects between the
fixing flange and diamond blade.During disassembly,avoid
useoftoolsthatcoulddentor deformthe flange.
7.Insertthe newblade proceeding inreverseorder ofthe
operation described atpoint4.Takespecialcare toensure
correct direction ofrotation ofthe diamond blade.
8.Tighten the blade locknutfullydownbyrotating
anticlockwise(left thread),toatorque of40 Nm.
9.Takethe shaftblocking pinoffthe beltcover.
10.Verifythe blade turn freely.
11.Connect the plug again.
-Note that theblademust have anexternaldiameter
of300 mm, acentralholediameterof25.4mm and max.
thickness of3mm.
-Check that thebladetobeusedissuitablefor the
materialtobecut.
-Neverdrycutmaterialorcutwhencooling
waterlevelsarelow.
-Donotuse blades for wood!(fig.6).
15. USE
-Leave aspace of150cmaroundthe
machinetooperateinfull safety.
-Donotallowother personstoapproachthe
machineduringcutting.
-Never usethe machineinfire-risk areas.Sparks
cancausefireorexplosions.
-Makesurethatthemachine isswitchedoffbefore positioning or
handling.
-Always ensure thatthe blade isfree ofanycontact beforestart-
up. -Ensurecorrectinstallationofallprotectivedevices.
Before starting work,fill the water tank. Topup during operation
whenever necessary:N.B. thepumpsuction hosemust
alwaysremainimmersedinwater.
-Insertthe pluginthe powersocket.

15.3CUTTING
-Check that thebladeisalignedwiththecutting line.
-Placetheworkpieceon theworktable(ref.8,fig.1),restingfirmly
against thestop. Startthemotor.
Waituntil thewaterreachestheblade.Begincutting.
-Horizontalcuttingmovementiscarriedoutbypullingthe carriage

-As cutting thickness increases,thebladeissubjected
togreaterstress.Toavoidoverloading themotor,the
operator shouldcontinuallycheck bladefeedspeed.The
speedwillalsodependonthecharacteristicsofthe
materialbeing cut(hardness,toughnessetc.).

15.3.2BLADECHANGE
Tochange the blade refer tosection 13.
16.MAINTENANCE
-WARNING! Servicing must always becarriedoutby
qualifiedtechniciansand onlyafterthemotor has been
switchedoff.
-Alwayskeeptheguardsinproperworkingorder
andfreefromdamage.
-Asthereisthecontinuousriskofinadvertent
damagetotheelectriccables,these must bechecked
regularlyeachtimebeforethemachineisused.
Never leavethe machine outinthe open.Makesure thatitis

conditions.
Belowisalist ofthe cleaning operationsthatmust be carried out
atthe end ofeveryshift.
16.1TANKCLEANINGONWORKCOMPLETION
-Emptythe tankbyremoving the plug.Removecutting residue
using ajetofwater.
16.2WORKSURFACECLEANING
Alwayskeepworksurfacesclean.Residualdirtcanimpaircutting
precision.
16.3GUIDERAILCLEANING
It isgood practicetoremoveall tracesofdirtfromthe guides.
16.4CLEANINGAND MAINTENANCEOF COOLING
CIRCUIT
-If water doesnotreachthe blade stop the machine immediately
toavoidblade damage.
-After switching offthe machine ensure thatthe water levelis
sufficient.
At regular intervals(or when the flowrateofthe blade cooling
water isreduced) clean the cooling water supplycircuit. Todo
this, disassemblethe deliverynozzlelocated inside the blade
guard and clean inwater.
Periodicallyclean the cooling water deliveryline between the
pumpand valve,and blade guard using water.
16.5TENSIONINGTHEDRIVE BELT(fig.8)
-Switchoff theelectricmotor andremovetheplug fromthe
power supply.
-Unscrewthe4screwsthatsecurethemovablebeltguard
(ref.1).
-Loosen the 4(ref. 2) screwsthatclampthe electricmotor to
the blade support.
-Tension the beltusing the nut(ref. 3):applyaforceofabout
F=6Kgtothe centre ofthe free section ofthe belt, the arrow
shouldbe about f=6mm (fig.9).
-Tightenthescrewsonthe electricmotor,checkingthe
alignmentof the motor pulley and the blade pulley
-Refitthe guard and lock itusing the 4screws.
-To avoidshortening thelife ofthebelt,thebearings
andthebladeshaft,do notovertensionthebelt.Finally,
checkthetwopulleysarealigned
16.6DRIVE BELTREPLACEMENT
Repeatthe operationsdescribed insection 16.5,replacing the
beltbefore tensioning it
17.REPAIRS
