Safety

Improperuseormaintenancebytheoperatoror ownercanresultininjury.Toreducethepotential forinjury,complywiththesesafetyinstructions andalwayspayattentiontothesafetyalert symbol,whichmeansCAUTION,WARNING,or DANGER-"personalsafetyinstruction."Failureto complywiththeinstructionmayresultinpersonal injuryordeath.

SafeOperatingPractices

–Neverrefuelordraintheaeratorindoors.

•Checkthattheoperatorpresencecontrols,safety switchesandshieldsareattachedandfunctioning properly.Donotoperateunlesstheyarefunctioning properly.

Operation

•Onlyoperateingoodlight,keepingawayfromholes andhiddenhazards.

•Besurealldrivesareinneutralandparkingbrakeis engagedbeforestartingengine.Starttheengineonly fromtheoperatorsposition.

ThefollowinginstructionsarefromANSIstandard B71.4-2004.

Training

•ReadtheOperator’sManualandothertraining material.Iftheoperator(s)ormechanic(s)cannot readEnglishitistheowner’sresponsibilitytoexplain thismaterialtothem.

•Becomefamiliarwiththesafeoperationofthe equipment,operatorcontrols,andsafetysigns.

•Alloperatorsandmechanicsshouldbetrained.The ownerisresponsiblefortrainingtheusers.

•Neverletchildrenoruntrainedpeopleoperateor servicetheequipment.Localregulationsmayrestrict theageoftheoperator.

•Theowner/usercanpreventandisresponsiblefor accidentsorinjuriesoccurringtohimselforherself, otherpeopleorproperty.

Preparation

•Evaluatetheterraintodeterminewhataccessories andattachmentsareneededtoproperlyand safelyperformthejob.Onlyuseaccessoriesand attachmentsapprovedbythemanufacturer.

•Wearappropriateclothingincludinghardhat,safety glassesandhearingprotection.Longhair,loose clothingorjewelrymaygettangledinmovingparts.

•Inspecttheareawheretheequipmentistobeused andremoveallobjectssuchasrocks,toysandwire whichcanbecontactedbytheaerator.

•Useextracarewhenhandlinggasolineandother fuels.Theyareammableandvaporsareexplosive.

–Useonlyanapprovedcontainer.

•Neveroperatewithouttheshields,coversorother guardssecurelyinplace.Besureallinterlocksare functioningproperly .

•Keephandsandfeetawayfromthenozzleand rollerarea.Highvelocitywaterjetscanpenetrate handsandfeet.Penetrationbythehighvelocity waterjetscancauseseriouspersonalinjury.If accidentalpenetrationoccurs,seekmedicalattention immediately.

•Neverusechemicalsinthewatersupplysystem.

•Donotoperatethewaterinjectionsystem onconcreteorasphaltbecausewaterjetswill permanentlydamagethesesurfaces.

•Beforedisconnectingorperforminganyworkon thewatersystem,allpressureinthesystemmust berelievedbystoppingtheengineandopeningthe bleedvalve.Openingthebleedvalveallowsany trappedwatertoescapefromthesystemandalso allowstheaccumulatorpistontomovetothebottom oftheaccumulatorcylinder.

•Donotchangetheenginegovernorsettingor overspeedtheengine.

•Theaccumulatorinthismachinecontainshigh pressuredrynitrogen.Accumulatorservicing requiresspecialtoolsandprecautions.Accumulators donotcontainuserserviceablecomponents. Improperaccumulatorservicingcancause dismembermentordeath.Donotattemptto disassembleanaccumulator;havethisworkdoneby anAuthorizedToroDistributor.

•Stoponlevelground,disengagedrives,engage parkingbrake,shutoffenginebeforeleavingthe operator’spositionforanyreason.

•Nevercarrypassengersandkeeppetsandbystanders away.

–Neverremovegascaporaddfuelwithengine

running.Allowenginetocoolbeforerefueling. Donotsmoke.

•Bealert,slowdownandusecautionwhenmaking turns.Lookbehindandtothesidebeforechanging directions.

Owner Responsibilities

As the Product owner, you are responsible for required maintenance and adjustments stated in your Operator’s Manual. Failure to perform required maintenance and adjustments can be grounds for disallowing a warranty claim.

Items and Conditions Not Covered

Not all product failures or malfunctions that occur during the warranty period are defects in materials or workmanship. This warranty does not cover the following:

Product failures which result from the use of non-Toro

• replacement parts, or from installation and use of add-on, or modiﬁ ed non-Toro branded accessories and products. A separate warranty may be provided by the manufacturer of these items. Product failures which result from failure to perform recom-

• mended maintenance and/or adjustments. Failure to properly maintain your Toro product per the recommended maintenance listed in the Operator’s Manual can result in claims for warranty being denied. Product failures which result from operating the Product in an

• abusive, negligent or reckless manner. Parts subject to consumption through use unless found to

• be defective. Examples of parts which are consumed, or used up, during normal Product operation include, but are not limited to, brake pads and linings, clutch linings, blades, reels, rollers and bearings (sealed or greasable), bed knives, aerator crankshaft and stomper arm bearings, tines, spark plugs, castor wheels and bearings, tires, ﬁ lters, belts, and certain sprayer components such as diaphragms, nozzles, and check valves, etc.

Failures caused by outside inﬂ uence. Conditions considered

• to be outside inﬂ uence include, but are not limited to, weather, storage practices, contamination, use of unapproved coolants, lubricants, additives, fertilizers, water, or chemicals, etc. Normal noise, vibration, and deterioration, “wear and tear”.

• Normal “wear and tear” includes, but is not limited to, damage to seats due to wear or abrasion, worn painted surfaces, scratched decals or windows, etc.

Parts

Parts scheduled for replacement as required maintenance are warranted for the period of time up to the scheduled replacement time for that part. Parts replaced under this warranty are covered for the duration of the original product warranty and become the property of Toro. Toro will make the ﬁ nal decision whether to repair any ex- isting part or assembly or replace it. Toro may use remanufactured parts for warranty repairs.

Maintenance is at Owner’s Expense

Engine tune-up, lubrication cleaning and polishing, replacement of ﬁ lters, coolant, and completing recommended maintenance are some of the normal services Toro products require that are at the owner’s expense.

General Conditions

Repair by an Authorized Toro Distributor or Dealer is your sole remedy under this warranty.

Neither The Toro Company nor Toro Warranty Company is liable for indirect, incidental or consequential damages in connection with the use of the Toro Products covered by this warranty, including any cost or expense of providing substitute equipment or service during reasonable periods of malfunction or non-use pending completion of repairs under this warranty. Except for the Emissions warranty referenced below, if applicable, there is no other express warranty. All implied warranties of merchantability and ﬁ tness for use are limited to the duration of this express warranty.

Some states do not allow exclusions of incidental or consequential damages, or limitations on how long an implied warranty lasts, so the above exclusions and limitations may not apply to you. This warranty gives you speciﬁ c legal rights, and you may also have other rights which vary from state to state.
