STORAGE (1 month or longer) Storing Chain Saw (1 month or longer) 1. 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. 2. Clean all foreign material from the saw. Store it in a well- ventilated place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts. 3. 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.
