StoRING A cHAIN SAW
Storing a chain saw for longer than 30 days requires
storage maintenance. Unless the storage instruc-
tions are followed, fuel remaining in the carburettor
will evaporate, leaving gum-like deposits. This could
lead to difficult starting and result in costly repairs.

for longer than 30 days without performing the
following procedures.
1. Remove the fuel tank cap slowly to release any
pressure in tank. Carefully drain the fuel tank.
