Inspectthoroughlyfor damage.Repairanydamagebefore startingand operating. • startingthe engine. Neverstorethe machineor fuel containerinsidewhere thereis an open flame,sparkor pilotlight (e.g.furnace, waterheater,space heater,clothesdryer etc.). • Allowmachineto cool at least5 minutesbeforestoring. Neverfill containersinsidea vehicleor on a truckor trailer bed with a plasticliner.Alwaysplacecontainerson the groundawayfromyourvehicle beforefilling. • • • OPERATION • Do not puthandsor feet near rotatingparts,in the auger/impeller housingor chuteassembly.Contactwith the rotatingpartscan amputatehandsand feet. • Theauger/impellercontrol leveris a safetydevice.Neverbypass its operation.Doingso makesthe machineunsafeand may cause personalinjury. Thecontrol leversmustoperateeasilyin bothdirectionsand automaticallyreturnto the disengagedpositionwhenreleased. • • • • • Planyoursnow-throwingpatternto avoiddischargetowards windows,walls,cars etc. Thus,avoidingpossibleproperty damageor personalinjurycausedby a ricochet. Neverdirect dischargeat children,bystandersand petsor allow anyonein front of the machine. • If gasolineis spilled,wipeit off the engineand equipment. Movemachineto anotherarea.Wait5 minutesbefore If possible,removegas-poweredequipmentfrom thetruck or trailerand refuelit on the ground.If this is not possible, then refuelsuch equipmenton a trailerwith a portable container,ratherthan from a gasolinedispensernozzle. Keepthe nozzlein contactwith the rimof the fueltank or containeropeningat all timesuntil fuelingis complete.Do notuse a nozzlelock-opendevice. Exerciseextremecautionwhenoperatingon or crossinggravel surfaces.Stay alertfor hidden hazardsor traffic. Exercisecautionwhenchangingdirectionand whileoperatingon slopes. • Disengageall controlleversand stop enginebeforeyouleave the operatingposition(behindthe handles).Wait untilthe auger/ impellercomesto a completestop beforeuncloggingthechute assembly,makingany adjustments,or inspections.
