The fuel expands and excess pressure can
build up in the tank. Fuel can escape as a
spray when the fuel tank cap is opened. The
escaping fuel can ignite. This may result in
serious injury to the user.
►Allow the blower to cool down first and then
open the tank cap carefully.
■ Clothing that has been in contact with fuel or
gasoline will ignite more easily. Persons may
be seriously or fatally injured, and property
may be damaged.

can harm the environment.
► Do not spill fuel, gasoline or two-stroke
engine oil.
4 Safety Precautions English
0458-459-0121-E 5
► Dispose of fuel mix, gasoline and two-
stroke engine oil in accordance with local
regulations and environmental require‐
ments.

8.1 Mixing fuel
The fuel required for this blower is a mixture of
two-stroke engine oil and gasoline in a mixing
ratio of 1:50.
STIHL recommends you use STIHL MotoMix.
If you mix the fuel yourself, use only STIHL two-
stroke engine oil or another high-performance
engine oil classified as JASO FB, JASO FC,
JASO FD, ISO-L-EGB, ISO-L-EGC or ISO-L-
EGD.
STIHL specifies STIHL HP Ultra two-stroke
engine oil or an equivalent high-performance
engine oil in order to maintain emission limits
over the machine’s service life.
► Make sure that the octane number of the gas‐
oline is at least 90 RON and the ethanol con‐
tent is not more than 10% (for Brazil: 27%).
► Make sure the two-stroke engine oil you are
using meets requirements.
► Depending on the desired amount of fuel,
determine the correct amounts of two-stroke
engine oil and gasoline in a mixing ratio of
1:50. Examples for fuel mixes:
–20 ml Two-stroke engine oil, 1 l gasoline
–60 ml Two-stroke engine oil, 3 l gasoline
–100 ml Two-stroke engine oil, 5 l gasoline
► Pour two-stroke engine oil into a clean
approved fuel canister first and then add gaso‐
line.
