Storing Chain Saw

WARNING: Stop engine and allow to cool, and secure the unit before storing or transporting
in a vehicle. Store unit and fuel in an area where fuel vapors cannot reach sparks or open
flames from water heaters, electric motors or switches, furnaces, etc. Store unit with all
guards in place. Position so that any sharp object cannot accidentally cause injury to
passersby. Store the unit out of reach of children and other unauthorized persons.
1. Drain and clean the fuel tank in a well ventilated area.
2. Drain all fuel from tank into a container approved for gasoline. Run engine until it stops. This will remove all
fuel-oil mix which could become stale and leave varnish and gum in the fuel system.
3. Clean all foreign material from the saw. Keep away from corrosive agents such as garden chemicals and
de-icing salts.
4. Abide by all Federal and local regulations for the safe storage and handling of gasoline. Excess fuel should
be used in other 2-cycle engine powered equipment.
CAUTION: It is important to prevent gum deposits from forming in essential fuel system
parts such as the carburetor, fuel filter, fuel hose, or fuel tank during storage. Alcohol
blended fuels (called gasohol or E10 or using ethanol, methanol) can attract moisture which
leads to fuel mixture separation and formation of acids during storage. Acidic gas can
damage the engine.
