SafeOperationPractices forRide-on(riding)Rotary LawnmowerMachines
ThismachinemeetsorexceedsEuropeanStandardsin effectatthetimeofproduction.However,improper useormaintenancebytheoperatororownercan resultininjury.Toreducethepotentialforinjury, complywiththesesafetyinstructionsandalwayspay attentiontothesafetyalertsymbol,whichmeans CAUTION,WARNING,orDANGER-“personal safetyinstruction.”Failuretocomplywiththe instructionmayresultinpersonalinjuryordeath.
SafeOperatingPractices
ThefollowinginstructionsarefromtheENstandard EN836:1997.
Thisproductiscapableofamputatinghandsand feetandthrowingobjects.Alwaysfollowallsafety instructionstoavoidseriousinjuryordeath.
Training
•Readtheinstructionscarefully.Befamiliarwiththe controlsandtheproperuseoftheequipment.
•Neverallowchildrenorpeopleunfamiliarwiththese instructionstousethelawnmower.Localregulations canrestricttheageoftheoperator.
•Nevermowwhilepeople,especiallychildren,orpets arenearby.
•Keepinmindthattheoperatororuserisresponsible foraccidentsorhazardsoccurringtootherpeopleor theirproperty.
•Donotcarrypassengers.
•Alldriversshouldseekandobtainprofessional andpracticalinstruction.Suchinstructionshould emphasize:
–theneedforcareandconcentrationwhen
workingwithride-onmachines;
–controlofaride-onmachineslidingonaslope
willnotberegainedbytheapplicationofthe brake.Themainreasonsforlossofcontrolare:
◊insufcientwheelgrip;
◊beingdriventoofast;
◊inadequatebraking;
◊thetypeofmachineisunsuitableforitstask;

◊lackofawarenessoftheeffectofground
conditions,especiallyslopes;
◊incorrecthitchingandloaddistribution.
–stayalertforhumpsandhollowsandother
hiddenhazards;
•Usecarewhenpullingloads.
Preparation
•Whilemowing,alwayswearsubstantialfootwearand longtrousers.Donotoperatetheequipmentwhen barefootorwearingopensandals.
•Thoroughlyinspecttheareawheretheequipment istobeusedandremoveallobjectswhichmaybe thrownbythemachine.
•Warning-Fuelishighlyammable.
–Storefuelincontainersspecicallydesignedfor
thispurpose.
–Refueloutdoorsonlyanddonotsmokewhile
refuelling.
–Addfuelbeforestartingtheengine.Never
removethecapofthefueltankoraddfuelwhile theengineisrunningorwhentheengineishot.
–Iffuelisspilled,donotattempttostartthe
enginebutmovethemachineawayfromthe areaofspillageandavoidcreatinganysourceof ignitionuntilfuelvaporshavedissipated.
–Replaceallfueltanksandcontainercapssecurely.
•Replacefaultysilencers.
•Beforeusing,alwaysvisuallyinspecttoseethatthe blades,bladeboltsandcutterassemblyarenotworn ordamaged.Replacewornordamagedbladesand boltsinsetstopreservebalance.
•Onmulti-bladedmachines,takecareasrotatingone bladecancauseotherbladestorotate.
–Useonlyapproveddrawbarhitchpoints.
–Limitloadstothoseyoucansafelycontrol.
–Donotturnsharply.Usecarewhenreversing.
•Watchoutfortrafcwhencrossingornearroadways.
•Stopthebladesrotatingbeforecrossingsurfaces otherthangrass.
•Whenusinganyattachments,neverdirectdischarge ofmaterialtowardbystandersnorallowanyonenear themachinewhileinoperation.
•Neveroperatethemachinewithdamagedguardsor withoutsafetyprotectivedevicesinplace.
•Donotchangetheenginegovernorsettingsor overspeedtheengine.Operatingtheengineat excessivespeedcanincreasethehazardofpersonal injury.
•Beforeleavingtheoperator’sposition:
–disengagethepowertake-offandlowerthe
attachments;
–changeintoneutralandsettheparkingbrake;
–stoptheengineandremovethekey.
•Disengagedrivetoattachments,stoptheengine, anddisconnectthesparkplugwire(s)orremovethe ignitionkey
–beforeclearingblockagesoruncloggingchute;
–beforechecking,cleaningorworkingonthe
lawnmower;
Operation
•Bealert,slowdownandusecautionwhenmaking turns.Lookbehindandtothesidebeforechanging directions.
•Donotoperatetheengineinaconnedspacewhere dangerouscarbonmonoxidefumescancollect.
•Mowonlyindaylightoringoodarticiallight.
•Beforeattemptingtostarttheengine,disengageall bladeattachmentclutchesandshiftintoneutral.
•Donotuseonslopesofmorethan15degrees.
•Rememberthereisnosuchthingasasafeslope. Travelongrassslopesrequiresparticularcare.To guardagainstoverturning:
–donotstoporstartsuddenlywhengoingupor

–uselowspeedsonslopesandduringtightturns;
–afterstrikingaforeignobject.Inspectthe
lawnmowerfordamageandmakerepairsbefore restartingandoperatingtheequipment;
–ifthemachinestartstovibrateabnormally(check
