3.12Fillingthemower’senginewithoil
Fortransportreasons,yournewmower’senginedoesnotcontainoilwhen
despatchedfromthefactory.Beforeuse,ensurethatthemowercontainsoil.
WARNING:Neverruntheenginewithoutoilevenforashortperiod.

•AlwaysuseahighqualityoilofAPISF
standardsandSAE30or15W40viscosity.
•Whenfillingtheenginewithoil,position
themoweronafirm,levelsurfaceUnscrew
theoilfillercapandremovethedipstick
(fig.5).
•Slowlypourintheoil.Thecorrectcapacity
oftheengine’soilsumpis650ml.
•Insertthedipstickuptothefillerneckbut
donotscrewitin.Removethedipstickand
readtheoillevelbyholdingthedipstick
horizontally.
•Theoillevelmustreachthemaximummarkonthedipstick(fig.6)
•Iftoomuchoilhasbeenaddedtotheengine,theexcesscanbedrained
outbytippingthemowerontoitssidewiththeairfilterand

caretoavoidriskofburns,fireorexplosion.Thefueltankshouldbefilled
beforestartingtheengine.Yourmower’senginerunsonpetrolalone‐donot
addoiltothepetrol.
Alwaysuseunleadedpetrolofaminimum95RON.Buyonlythequantityof
fuelthatyouplantouseinamonth.Nevertransportandstorepetrolother

fuelcontainer’sspout(fig.7)orafunnel.
•Thetank’scapacityisabout1litre.Avoid
spillagesbynotoverfillingthetank.Leave
about13mmspacebeneaththethreaded
collartoallowforfuelexpansion.
•Iffuelshouldoverflow,donotstarttheengine.Movethemoweraway
fromtheplaceofspillageandcarefullywipedownthemower.Any
attemptatstartingshouldbeavoideduntilpetrolvapourshave
completelygone.
•Replacesecurelythecapsonthefueltankandthefuelcontainerand
placethelatterinasecureplaceawayfromheatordirectsunlight.
•Beforeeachmowing,visuallyinspecttheconditionofthemower’sfuel
tankanditscap,thefueldeliverypipeandthefuelfilter.

Ifafuelleakisseenorsuspected,donotstarttheengine.Drainthefuel
tankusingafuelsuctionpumpandimmediatelycontactanapproved
SANLIUKservicedealerforadvice.

Ifpossible,mowonlywhenthegrassisdry.Ifthegrassiswetorexcessively
long,performtwocuttingpasses.Makethefirstpassatmaximumcutting
heighttoavoidoverloadingthemower.Thesecondpassshouldbemadeat
therequiredfinishedheight.Ifgrassbuildsupbeneaththemower’schassis,
stoptheengineandremovethesparkplug’scapbeforecleaningthe
undersideofthecutterdeck.

orheatsources.Ifthestorageareaisaccessibletochildren,immobilisethe
machinebydisconnectingthesparkplug’scap.
Storingthemowerbeneathatarpaulinorsimilarcoverisnot
recommendedasitmaycauseabuild‐upofcondensationresultingin
corrosion.

Extendedshutdownandwinterstorage
Thoroughlycleanthemower.Ideally,runtheengineoutdoorsuntilthefuel
tankisempty.Alternatively,emptyanyremainingfuelusingafuelsuction
pump.TurnthefueltaptotheOFFposition(fig13).
Disposeofdiscardedfuelsafelyandresponsibly,rememberingthatpetrol

3.33Mowermaintenance
Cuttingsystem
Beforeandaftereachmowingsession,checkthattheblade,itsattachment
boltsanddriveshaftarenotdamagedorexcessivelyworn.Nevertryto
straightenabentblade.Replaceadamaged,wornorbentbladeassoonas
possible.UseonlygenuineSANLIpartsorthoseapprovedbySANLIUK.
Excessivevibrationwhenmowingisagoodindicationofaproblemwith
thecuttingsystem.

WARNING:Vibrationfromabentordamagedbladecancausecostlydamage
tothemower.Workingwithanexcessivelywornbladewastesfuelandcan
leadtoinjuryifthebladebecomesdetachedfromthemachine.

Sharpeningtheblade
Forbestmowingresults,havetheedgessharpenedandthebladebalanced
atleastonceayearbyaspecialistservicedealeroragent.

Removingtheblade
Wearappropriateprotectiveglovestopreventpossibleinjurywhen
handlingtheblade.Disconnectthesparkplugcapandtiltthemoweronits
sidewithairfilterandcarburettorsideuppermost.
Holdingthebladefirmlyinonehand,useaspannerorsockettoloosenthe
bladescrew.


AirFilter
Anairfilterinpoorconditionwillreducethe
performanceandlifeoftheenginewhilemaking
ithardertostart.Regularchecksaretherefore
essential,especiallywhenusingthemowerin
dustyconditions.Checkandcleantheairfilter
every25hoursofuseormoreofteniftheengine
isusedinadustyenvironment.
Removetheairboxlid(fig.18)andcarefullyremovethefoamfilter
cartridge.Cleanthecartridgeinasmallbowlofwarmwatercontaininga
fewdropsofwashing‐upliquiduntilitisperfectlycleanandfreefromall
tracesofgreaseanddust.Rinsethefiltercartridgeincleanwaterandthen

holdingthedipstickhorizontal.Theoillevelshould
bebetweentheminimumandmaximumoillevel
marksonthedipstick(fig.19).Addoilifnecessary
andrepeattheabovecheckingprocess.Runningthe
enginewithoutoilorwithtoolittleoilcancauseseriousenginedamage.

Changingtheoil
Thefirstoilchangeshouldbecarriedoutafterthefirst5hoursofmoweruse.
Thereafter,changetheoilafterevery25hours’useoratleastonceayear.
