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.
