Look For Relevant Emissions Durability Period and
Air Index Information On Your Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB)Tier 2 Emission Standards must display information regarding the Emissions Durability Period and the Air Index. Sears, Roebuck and Co., U.S.A. 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 is certified to be emissions compliant, assuming proper maintenance in accordance with the Operating & Maintenance 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 Emissions Durability 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. The lower 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, Roebuck and Co., U.S.A. engines will be certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 emission standards. For Phase 2 certified engines, the Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours 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.
The displacement engines of Model Series 210000 is 344 cc, 280000 is 465 cc, 310000 engines is 501 cc.
This is a generic representation of the emission label typically found on a certified engine.

longer than four weeks should be considered stale.
Fill fuel tank with clean, fresh, unleaded regular gasoline only. Do not use gasoline containing METHANOL. Replace fuel cap.
To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the fuel from the tank by running the engine until the fuel tank is empty. Use fresh fuel next season. See STORAGE section for additional information.
WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes, and other sources of ignition.
Check the fuel level periodically to avoid running out of gasoline while operating the Yard Vacuum. If the unit runs out of gas as it is chipping, it may be necessary to unclog the discharge area before it can be restarted. Refer to SERVICE AND ADJUSTMENT section on page 15.
TO STOP ENGINE
Move throttle control lever to STOP or OFF position.
Disconnect spark plug wire and ground it to the post to prevent accidental starting while the equipment is unattended.
Oil Viscosity Chart
Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, they will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.
Check the oil level making certain not to rub the dipstick along the inside walls of the oil fill tube. This would result in a false dipstick reading. Refill to FULL mark on dipstick, if necessary. Capacity is approximately 18 oz. Overfilling will cause the engine to smoke profusely and will result in poor engine performance.
Replace oil fill dipstick and tighten.
Keep oil level at FULL. Running the engine with too little oil can result in permanent engine damage.
Gasoline
Remove fuel cap from the fuel tank.
Make sure the container from which you will pour the gasoline is clean and free from rust or foreign particles. Never use gasoline that may be stale from long periods of storage in its container. Gasoline that has been sitting for any period

STORAGE
Prepare your Craftsman Yard Vacuum for storage at the end of the season or if the unit will not be used for 30 days or longer. A yearly check-up by your local Sears Parts & Repair Center is a good way to ensure that the unit runs properly next season.
Yard Vacuum
Clean the equipment thoroughly.
Wipe equipment with an oiled rag to prevent rust. Use a light oil or silicone to wipe.
Service the engine following instructions below.
Store unit in a clean, dry area. Do not store next to corrosive materials such as fertilizer.
Engine
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the carburetor, fuel filter, fuel hose, or tank during storage. Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.
NOTE: Fuel stabilizer is an acceptable alternative to
emptying the tank of fuel in minimizing the formation of fuel gum deposits during storage.
Do not drain the gas tank and carburetor if using fuel stabilizer.
In all cases, drain all the oil from the crankcase (this should be done after the engine has been operated and is still warm) and refill the crankcase with fresh oil.
If you do not use a fuel stabilizer, follow these instructions:
Drain the fuel from the tank by running the engine until the fuel tank is empty.
Remove spark plug, pour approximately 1/2 ounce (approximately one tablespoon) of engine oil into cylinder and crank slowly to distribute oil.
Replace spark plug.
Other
Do not store gasoline from one season to another.
Replace the gasoline can if it starts to rust. Rust and/or dirt in the gasoline will cause problems.
Store unit in a clean, dry area. Do not store next to corrosive materials, such as fertilizer.
NOTE: If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coat­ing with a light oil or silicone.
Add stabilizer to gasoline in fuel tank or storage container.
