WARRANTYANDRETURNS
WARRANTYPOLICYFORLAVINA®S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 United 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 herein is non-transferable, and only applies to the original owner or purchaser of the machine.
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.

SAFEUSE 
TheLAVINA®25G‐Sisdesignedtoeliminateall
risks correlated
withitsuse.However,itisnotpossibleto
eliminate therisksof
aneventualaccidentwiththemachine.
Unskilled 
oruninstructedoperatormaycausecorrelatedresidual
risks.
Suchrisks are: 
- PositionRisks duetooperator’sincorrect
workingposition 
- TanglingupRisksduetowearing
inappropriate working

PROPANESAFETY
Propaneisaflammablegaswhosevaporsareheavierthan
air.Asisthecasewithgasoline,propanecanexplodeifthe
propercautionsarenotheeded.Propaneisodorizedwithan
agenthavingadistinctodorthatisrecognizableatverylow
concentrations.Thishelpsinidentifyingleaks,evenwhenthey
aresmall.
Awarenessandbasicsafetyprecautionsarerequiredwhen
workingwithpropane.Aslongastheseprecautionsarefollowed,
riskisnegligible.Ignorance,however,couldposeneedlessrisk.
Thetwogreatesthazardswithpropanepoweredfloorcare
machinesare:
- CarbonMonoxidePoisoning:Thisisthemostfrequently
reportedincidentassociatedwithpropanepoweredfloor
caremachinesandiscausedbyexcessiveexhaustemissions.
Thesymptomsareheadache,dizzinessandnausea.Amajor
causeinvolvesengineswithpoorpreventive
maintenance
practices,usuallythosewithdirtyairfilters and machines
operatedinconfinedareas
without  adequate ventilation.
Anothercausemay
be substandard,inexpensivemachineswith
no
emissions controltechnology andimproperlyset
carburetion. 
- OverfilledFuelCylinders: Nearly all fire
related incidents
reported result from bringing a cylinder
into 
abuildingwithoutfirstcheckingforoverfill.This
action is
dangerous,unwise,and
unnecessary. 
FIRESAFETY 
Beawareofthepotentialdangersoffireor
explosion when
usingpropane,andtakenormalfire‐safety
precautions. 
Fire:ThereisapossibilityoffirefromLPGvaporleaking
or
ventingfromfuelcylindersorcarburetion equipment.
Explosion:LPGvaporconcentratedorconfinedtoa small,
restrictedspacemayexplodeor ignite. 
PropanemayexperienceaBLEVE,aboiling
liquid 
expandingvapor
explosion. 
EMISSIONS 
 Allpropanepoweredfloorcaremachines
produce emissions.
Mostareharmless,butsomearedangerousand
can befatal.
Carbonmonoxide(CO)posesthegreatestrisk,
since 
COcanbelethalwithinaslittleas30minutesexposure
at 
3,000partspermillion(ppm)
concentration. 
 Carbonmonoxideisaninvisible,odorless,colorless
gas
createdwhenfossilfuels(suchasgasoline,wood, coal,
propane,oilandmethane)burn incompletely . 
HAZARDCOMMUNICATION
AMaterialSafetyDataSheetforpropaneshallbe
posted in
allbuildingswherepropanewillbe
used. 
Becausepropaneisodorized,itiseasilydetectedatlevels
of
justafewpartspermillion,whichismuchlessthan the
exposurelimitof1000partsper million. 
Ifyousmellpropanewhileoperatingapropanefloor
care
machine,dothe following: 
Stopthe
engine : 
1. Pullthethrottletothestopposition(ifpresent)
or turn
thekeyswitchtotheoff
position. 
2. Shutofftheservicevalveonthepropane
cylinder. 
3. Movethefloormachinetoawell‐ventilated
area. 
4. Removethecylinderfromthemachineandtake
it
outsidethe building. 
5. Ifthecylinderisleaking,contactaDOT
approved repair
shoptodeterminethecauseoftheleak
and havethe

TESTING
Thereareagreatnumberofinstrumentsofferedon
the
markettotestfortoxicgases.Onlythosedesignedto read
carbonmonoxideresultingfromcombustionengines is
consideredacceptablefortestingexhaustemissions from
propanepoweredfloor machines. 
Someinstrumentsareusedtoread“ambientair”and
may
bedamagedifusedtotakereadingsinthemuffleror
tail
pipe.Selectingtheproperinstrumentisanimportant part of
meetingthetesting
requirements.
Generallyspeaking,unitscapableofreadinginppm,
(parts
permillion),atrangesfrom0to1000areadequate for
checkingambientair(airinthebreathingzoneof the
operator).Instrumentscapableoftesting carbon
monoxideintheexhaustshouldbeabletoreadfrom0
to 
atleast2000ppmandshouldbecertifiedby
the
manufacturerforthat purpose. 

OPERATOR
Theoperatormustknowthemachine’s work
environment.

Onlyoneoperatoratatimecanworkwiththe machine.
Theoperatormustbeproperlytrainedandwell instructed
prioroperatingthe machine.
Theoperatormustunderstandalltheinstructionsin this
manual.
Theoperatormustunderstandandinterpretall the
drawingsanddesignsin manual.
Theoperatormustknowallsanitationand safety
regulationspertainingtotheoperation of
Theoperatormusthavefloorgrinding experience.
Theoperatormustknowwhattodoincaseof emergency.
Theoperatormusthaveanadequatetechnical knowledge and
preparation.
Theoperatorisexpectedtooperatetheirequipment safely
andresponsibly.Theyareresponsibleforthe proper
handlingandstorageofpropanecylinders, identifying
potentialhazardsassociatedwithhisjoband avoiding
thesehazardsatall times.
PROPANECYLINDERS
ThePropanecylindersareconstructedofeither
aluminum or
steel.Werecommendaluminumbecauseitis
lighterand 
guardsagainstrusting.Thecylinderusedon
propane powered
floormachinesisclassifiedasa4E240
cylinder.Its rated
capacityis20lbs.andthisdesignationrefers
to themodelof
thecylinder.Actualpropane
capacity 
achievedduringfillingcanbelessthan,equalto,or
slightly
morethan20lbs.UseonlyUL,CTC/DOTlisted cylinders. 
 Thepropanecylinderusedonthefloormachineisa
motor fuel
cylinderaslistedbytheDepartmentof
Transportation. Unlike
thecommon20‐lbpropaneoutdoorgrill
cylinders (whicharenot
legalforuseonpropanefloor
machines), 
themotorfuelcylinderhasanumberofsafety
systems 
designedintoittoensureyoursafetyatall
times. 
 Therearetwotypesof20lb.motorfuel
cylinders.
Liquid
draw 
Vapor
draw 
 Theliquiddrawcylinderisusedonlargervehicles
like forklifts.
Thesemachineshavespecial
vaporizing carburetorstoallow
thepropanetochangefroma
liquid toagasbeforebeing
burnedinthecombustion
chamber. 
 Thevapordrawcylinderisusedonsmallmachineslike
the
propanepoweredfloorcaremachines.The vacuum generated
bytheenginedrawsupthePropanegas
vapor throughthefuel
system.Thepropanepoweredfloor
care machinedoesnothave
anevaporatingsystemand
will freezeupifliquidpropaneis
introducedtoit.It
isnecessary thatspecialattentionbepaidto
ensure
that neithertheliquidnorthevapordrawcylinders be
overfilled.

REFUELLINGCYLINDERS
Theproperfillingofpropanecylindersisasubject
so important
thatitwarrantsspecialattention.
Propane cylindersshouldonly
befilledbyqualifiedpropane
dealers. 
 Mostimportant,propanecylindersshouldbefilled
no
morethan80%oftheirratedcapacity.Theother
20%, whichis
about4”(10cm)fromthetopofthecylinder,
is calledthevapor
spaceorheadspace.Thisvaporcan
be compressedwithout
causingthepressurereliefvalve
to openandventgastothearea
aroundthecylinder.If
there isnoheadspacetoallowforfuel
expansion,the
pressure reliefvalvewillopen,releasingpropane
gasinto
the atmosphere.Thisisaverydangerousandvolatile
situation asthereisalwaysthepossibilitythatenoughofthe
vented gascouldfinditswaydowntothefloorandcome in
contactwithapilotlightfromafurnace,hotwater heater, or
othersourceofignition.

unprotectedskintopropanegasorliquidcouldresultin
frostbiteinjury.
Allnewcylindersshouldbeventedandpurgedofairper
manufacturer’sinstructionsbeforeuse.Neverbleedpropane
cylindersindoors.
STORAGECYLINDERS
Whennotinuse,propanecylindersalwaysshould
be stored
outsideinanuprightpositionina
secure, tamperproof,steel
meshstoragecabinet.This
cabinet maybelocatednextto
thebuildingbutwithatleast
five 
feet(1.5m)ofspacebetweenthecabinetandthe
nearest 
buildingopening(doororwindow),alsoawayfrom
heat
anddirect sunlight. 
 Donotinstallthecabinetnearastairwayor
streetelevator
asventedpropanegaswillseekalower level sinceitis
heavierthanairandcouldfinditswayinto
the basementof
thebuilding.Donotstorecylindersfull
or emptyinsidea
buildingorinsideavehicle.Althoughit
is unlikelythat
propanewillventfromastoredcylinder,if
it should,the
vaporcouldcomeincontactwithan
ignition sourcesuchas
asparkfromapowertoolor
other applianceandcreatea
flash
fire. 
 Donotsmokeoruseadevicewithanopenflame
when
handlingortransportingpropane cylinders.



TRANSPORTINGCYLINDERS
Whentransportingcylinderstoapropanedealerorto a job,
makesurethecylindersaresecurelyfastened
and standingin
anuprightpositionwiththeservice
valveclosed. 
Acylinderrattlingaroundinthebackofavehicle and 
bangingintootherobjectsconstitutesahazard.
Avoid
droppingorbangingcylindersagainstsharp objects. 
Thepropanecylindersaresturdilyconstructedbuta series
ofhardjoltscouldcause damage. 
Pleasenotethatanycylinderthathasbeenfilledis always 
consideredfull,nomatterhowlittlepropanegas
remains
in
it.Thisisbecauseevenwhenallliquidhas evaporated
intovaporthereisstillsomepropanegasvaporleftin the
cylinder.Becausethisremainingfuelisflammable, an
emptycylindershouldbetreatedwiththesame careful
proceduresasonethatisfilledtothe80%levelwith liquid
propane.Theonlytimethatacylinderisconsidered
empty iswhenitisnew,beforeithasbeenfilledwith
propane. 
Whentransportingapropanepoweredfloormachine,
the
propanecylindermaybestrappedontothemachine as
longasthemachineitselfisfirmlysecuredinthe vehicle. 
 Ofcourse,sparecylindersshouldalwaysbesecuredin
an
upright position.

oxygensensordoesnotreactto
nor doesitmeasuretheCOcontentoftheexhaust.Itrespondsonly
tooxygen
content. 
TheControlModuleissettoignorethereadingsfromtheoxygensensorduringthefirstthree

9. TROUBLESHOOTING
9.1ENGINE
Whentroublesoccur,be sure to check the simple causeswhichatfirst,mayseemtooobvioustobeconsidered.Forexample,
a startingproblemcouldbecausedbyfuelstarvationduetoanemptypropanecylinderoranunopenedservicevalve.Ifyou
do
not checkforthis,starterburnoutcould result. 
SomeTroublesand
solutions:
Surging idle 
Tosmoothouttheengines'idlecharacteristics,adjustmentisprovidedbyanidlescrewonthelowerleftsideofthecarburetor
as viewedfromtheoperator'sposition.Thescrewisbrightsteeland1/4"indiameterwithaPhillipsheadonit.Rotatingthe
screw clockwisewillincreasetheidlespeedandthisshouldcurethe"surgingidle".Ifitdoesnot,callourcustomer service. 
Enginestartsandidles,butwillquitasthethrottleis
advanced 
Itispossiblethatthepropanetank'sservicevalveisfaulty.Tocheckforthis,closethevalvecompletelyandthenreopen
very
slowlywhileyoulistenfora"click"whenthegasbeginstotravelthroughthevalve.Ifyouhearthisveryslightnoise,the
valve
is onlypartiallyopening.Thisallowsenoughgasthroughtostartandidletheengine,butnotenoughforfullthrottle
operation.
As thethrottleisincreased,allowingmoreairtoentertheintake,theenginewillquitfromfuelstarvation.Call
yourdealeror
the factoryforinstructionsonwheretohavetheservicevalvereplaced.Meanwhile,togetby,youcan
continuetoopenthe
service valveuntilyoudonotheara“click"andthentheenginewillrunnormally.Ifitdoesnot,call
yourcustomer
service. 
Starterbarelyturnstheengineoverorthesolenoidjust
clicks 
Thebatteryislikelylowincharge.Thiscanberemediedbyrechargingthebatteryusinga12Voltbatterychargerat
4.12 
amperes.Thebatteryislocatedundertheframeattherearofthebuffer.ThepositivepostistheonewiththeREDcable
attached toit.Followtheinstructionsthatcamewiththebatterycharger.REMINDER:thiswillcontinuetohappenunlessyour
engineis
run forsufficienttimebetweenstartstorechargethe battery 
9.2CHECKINGANDCHANGINGOIL
Checktheengineoillevel,screwthedipstickintogetreading.Whilechangingengineoil,checkforleakageofengineoilat the
