Fuel
Fuel lank cap open
The two-stroke engine is powered by a mixture of regular
gasoline and engine oil.
Never use high octane gasoline as it contains benzol which
will permanently damage the carburetor diaphragms.
Only use STIHL two-cycle engine oil or other branded
two-cycle engine oils for mixing. The mix ratio is 1:40
(1 part oil to 40 parts regular gasoline) with STIHL two-cycle
engine oil or 1:25 for other branded engine oils.
During the running-in period use a fuel-oil mixture of ratio
1: 25 for the first five tank fillings.
Important: Always shake mixture in fuel can vigorously
before fueling.
