• Keepthe nozzleincontactwith the rimof the fueltankorcontaineropeningat all timesuntil fuelingis complete.Donotuse a nozzlelock-opendevice.
OPERATION
• Do not puthandsor feetnear rotatingparts,in the auger/impellerhousingor chuteassembly.Contactwith the rotatingpartscanamputatehandsandfeet.
• Theauger/impellercontrol leveris a safetydevice.Neverbypassitsoperation.Doingso makesthe machineunsafeandmaycausepersonalinjury.
• Thecontrol leversmustoperateeasilyin bothdirectionsandautomaticallyreturnto the disengagedpositionwhenreleased.
• If the machineshouldstart to vibrateabnormally,stopthe engine,disconnectthe sparkplugwire andgroundit againstthe engine.Inspectthoroughlyfor damage.Repairanydamagebeforestartingandoperating.
• Disengageall controlleversandstopenginebeforeyouleavethe operatingposition(behindthe handles).Waituntilthe auger/impellercomesto a completestopbeforeuncloggingthechuteassembly,makingany adjustments,or inspections.

Look For Relevant Emissions Durability Period andAir index information On Your Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emission Standards mustdisplay information regarding the Emissions Durability Period and the Air Index. Sears Brands ManagementCorporation makes this information available to the consumer on our emission labels.
The Emissions Durability Period describes the number of hours of actual running time for which the engine iscertified to be emissions compliant, assuming proper maintenance in accordance with the Operating & Mainte-nance Instructions. The following categories are used:
Moderate: Engine is certified to be emission compliant for 125 hours of actual engine running time.
Intermediate: Engine is certified to be emission compliant for 250 hours of actual engine running time.
Extended: Engine is certified to be emission compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year. Therefore, the EmissionsDurability Period of an engine with an intermediate rating would equate to 10 to 12 years.
The Air index is a calculated number describing the relative level of emissions for a specific engine family. Thelower the Air Index, the cleaner the engine. This information is displayed in graphical form on the emissions label.
After July 1,2000, Look For Emissions Compliance Period
On Engine Emissions Compliance Label
After July 1, 2000 certain Sears Brands Management Corporation engines will be certified to meet the UnitedStates Environmental Protection Agency (USEPA) Phase 2 emission standards. For Phase 2 certified engines, theEmissions Compliance Period referred to on the Emissions Compliance label indicates the number of operatinghours for which the engine has been shown to meet Federal emission requirements.
For engines less than 225 cc displacement, Category C = 125 hours, B = 250 hours and A = 500 hours.
For engines of 225 cc or more, Category C = 250 hours, B = 500 hours and A = 1000 hours.
This is a generic representation of the emission label typically found on a certified engine.
