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.
1.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.
2.Replace oil fill dipstick and tighten.
3.Keep oil level at FULL. Running the engine with too little oil can result in permanent engine damage.
Gasoline
1.Remove fuel cap from the fuel tank.
2.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 longer than four weeks should be considered stale.
3.Fill fuel tank with clean, fresh, unleaded regular gasoline only. Do not use gasoline containing METHANOL. Replace fuel cap.
IMPORTANT: 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.
NOTE: 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 17.
FreshStart™ Gas Cap
This unit is equipped with a FreshStart™ continuous fuel preserver gas cap which automatically drips continuous fuel preserver into your fuel tank for up to six months depending on conditions, such as temperature, usage patterns, fuel type and blend. To activate the gas cap, follow the instructions below:
1.Snap the fuel preserver cartridge that comes with your unit into the fuel cap.
2.Peel off the white tab from the cartridge.
3.Twist the FreshStart™ cap onto the fuel tank.
When you visually see that the fuel preserver cartridge is empty, replacement cartridges are available through your local Sears Parts & Repair Center and most Sears stores.
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.
