WARRANTY AND RETURNS



WARRANTY POLICY FOR LAVINA® X MACHINES

A warranty card must be submitted to Superabrasive within 30 days of purchase in order for the foregoing warranty to

apply.

You can either mail a hard copy of the warranty card or submit it electronically - see page 2.

Superabrasive warrants, from the time of delivery and receipt by the original customer, new and unused products

sold by

Superabrasive or Superabrasive-appointed distributors or dealers. Goods shall be free from defects in

materials and

workmanship. Superabrasive or a Superabrasive-appointed repair facility shall either replace or

repair any defects in the

Goods resulting from faulty design, materials, or workmanship. Products repaired or

replaced during the warranty period

shall be covered by the foregoing warranty for the remainder of the original

warranty period, or ninety (90) days from date

of the repair or shipment of the replacement, whichever is longer.

Spare parts for repair will be either new or equivalent to

new.



Warranty period shall be 2 years from the time of delivery and receipt by the original customer, or 600 operating

hours on

the machine - whichever occurs first. Superabrasive will cover the shipping charges for the transportation

of the machine to

Superabrasive (or an approved repair facility) and back to the customer (within the contiguous 48

States) in the event

that the damage occurs and is reported within 200 operating hours. Shipping

charges, if

covered by Superabrasive, must be agreed upon in advance and approved by Superabrasive. Thereafter, the

customer will have to cover the shipping charges to Superabrasive and back. Superabrasive will not warranty

Goods after a

period of 2 years from the time of delivery and receipt by the original customer, or 600 operating

hours on the machine -

whichever occurs first.

Superabrasive shall not be liable for any defects that are caused by circumstances that occur after the Goods

have been

delivered and whilst the Goods are in the possession of the purchaser. Furthermore, the warranty

does not include normal

wear and tear or deterioration. Wear parts are not warranted. Superabrasive is not liable

for defects arising out of use of

non-OEM parts.

The Warranty is void if the purchaser has not followed the maintenance plan stipulated by the machine’s manual

and

warranty card. The warranty is void if the purchaser repairs said Goods himself, or if repairs are conducted by a

repair facility

that is not approved by Superabrasive. Superabrasive’s liability does not cover defects which are

caused by faulty

maintenance, incorrect operation, faulty repair by the purchaser, or by alterations conducted

without Superabrasive’s prior

written consent. The same applies to any alterations of the Goods or services

performed by another party other than

Superabrasive, a Superabrasive-appointed distributor, or a Superabrasive-

approved repair facility. The warranty is not

applicable on a defect that arises due to tools or parts that are not

original to Superabrasive. Replaced defective parts shall

be placed at Superabrasive’s disposal and shall become

property of Superabrasive. If such defective parts are replaced

within the warranty period, the shipping charges will be covered by Superabrasive. In warranty complaint cases,

when no

defects are found for which Superabrasive is liable, Superabrasive shall be entitled to compensation for

the labor, material

cost, and shipping charges, incurred by Superabrasive as as a result of the complaint.

The warranty herein is non-transferable, and only applies to the original owner or purchaser of the machine.

In no case, a machine is to be returned to Superabrasive Inc. for credit or repair without prior authorization.



GENERALDESCRIPTION

TheLAVINA®Xmachineisintendedforgrinding,polishingandbuffingconcrete,marble,granite,limestoneandterrazzosurfaces

withdiamondtools.Additionally,themachinecouldbeusedforgrindingwoodfloorsurfaces.

TheLAVINA®Xmachineisathree‐discmachine,whichcanbeuseddryaswellaswet.

Forbestresults,useonlytoolsmanufacturedorrecommendedbySuperabrasiveandits

distributors.

TheLAVINA®Xmachineismanufacturedandfittedfortheabove‐

mentionedapplicationsonly!Everyotherusemaycauseriskstothepersonsinvolved.



MACHINECHARACTERISTICS

TheLAVINA®Xmachineismadeoftwomaincomponentsections:



MAINDESIGN

Thetwomaincomponentsectionsarethecarriageandmainhead.

Thehandle(Fig.1.2)ontheframeisadjustableinheightandallowstheoperatortoworkina

correctandsafeworkingposture.

Thehalogenspotlight(Fig.1.2)enablestheoperatortoworkindarkerareas.

Existinglightingsystemdoesnotreplaceadequateoverheadlighting.

Thecontrolsarepositionedontopoftheelectricalbox(fig.1.3)

Theelectricalbox(fig.1.3)containstheelectricswitchesandtheinverter.

Themainfeedingcableisconnectedwithaplugandsocketontop.

Themotorfeedingcableispluggedintothesocketlocatedonthebottomofthebox.

Thetankisontheoppositesideoftheframe,sothattheweightofthewaterhasnoinfluenceon

theoperationofthemachine.Theframeweight,ontheotherhand,isfullyabsorbedbythe

drivingwheels.Anelectricpumpspraysthewaterthroughafrontsprayerorinternal.

Themotorismountedonthebaseplateanddrivesthethreeheadswithabeltsystem.

Theplanetaryheadisdrivenbyasecondbelt.



themachineinwell‐ventilatedareas.



ELECTRICALCONNECTION

Thevoltage(Volt)andcurrent(Ampere)aredisplayedonalabelon

theelectricalcontrolboxtoavoidanyincorrectconnection.Referto

thesebeforeconnectingthepower.Toavoidelectricalshocks,make

WATERFLOWCONTROLUNIT

Theoperatorcandirectwatertobesprayedinthefront

(Fig.4.1)bypositioningtheleverinthehorizontalposition;

thewaterwillsprayunderthecoverofthemachinewhen

theleverisintheverticalposition(Fig.4.2).Theflow

regulatingvalvelocatedonthetank(Fig.4.3)controlsthe

waterflowtotheworkingarea–infrontofthemachineor

underthemainheadcoverofthemachine.

STARTINGTHEMACHINE

FirstfollowthedirectionsinthechapteronSafetyDevicesandSafetyInstructions.Next,releasetheemergencystop(12),turnthe

Readyswitch(Fig.4.69)totheONpositiontoputthemachineinstandbymode.Checkthepotentiometer(8),andensurethatitis

settotheworkingspeed.Ifworkingwet,addwatertothefloorsurface.Ifworkingdryinsteadswitchonthevacuumunit.Finally,

holdthemachinefirmlyandpushtheRUNbutton(11).



OPERATINGTHEMACHINE

Guidethemachineinstraightlinesacrossthefloor,slightlyoverlappingthepreviouslycompletedsurfacewitheachnewline.Work

ataconstantspeed,allowingthetoolstimetoworkataspeedappropriateforthetools’gritsize.Avoidvibrations.Donotstopthe

machinewhiletoolsarestillrunningastheywillmarkthesurfaceofthefloor.Whenworkingwet,selectthedestinationofthewater

feedwiththewatertap(fig.4.2‐1)andperiodicallyrunthepump(fig.4.10‐11)toreleasewaterontothefloorsurface.Startingthe

pumpispossibleonlyifthemachinemotorison.Whenworkingdry,checkthefloorsurfaceperiodicallyfordustaccumulation.

Checkregularlytoseeifyourvacuumworksproperly



STOPPINGTHEMACHINE

Thestoppingofthemachinemustbedonegraduallyuntilthemotorstops.Donotstopmovingthemachinebeforethemotorcomes

torest,asthetoolscoulddamagethesurface.

Tostopthemachine:

1.PushtheSTOPbutton(10).

2.TurntheON/OFF(9)switchinpositionOFF,thiswillcutthevoltagetotheinvertorandthegreenlightwillturnoff.

WhileworkingdonotturnoffdirectlyfromtheREADYswitchorfromtheEmergencyStop,butfollowthestepsabove.



UsetheEmergencybutton(12)onlyinanemergency.

Remembernottoholdthemachineinonespotbeforeturningoffthemotor.



ALARM

TheResetbutton(4)willlightwhentheinvertergoesintoalarmmode.Themostcommonfailureismotoroverload.Toexitalarm

mode,pushtheresetbutton(4).Acodeontheinverter’sdisplayindicatesthetypeofthealarm.Whenthesamealarmisrepeated

severaltimes,itisimperativetofindandeliminatethecauseofit,otherwisetheinvertercanbecomedamaged.
