The fuel required for this brushcutter is a mixture
of gasoline and two-stroke engine oil, 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.
► Mix the fuel.
8.2 Filling the brushcutter with fuel

NOTICE
■ Exposure to light, direct sunlight and extreme
temperatures may accelerate fuel separation
or aging. The brushcutter can be damaged if it
is used with a fuel mix that has become sepa‐
rated or has aged.
►
Mix the fuel before topping up.
► Do not top up with fuel stored for more than
30 days (STIHL MotoMix: 5 years).
► When topping up, ensure that no fuel is spil‐
led and that the fuel level remains at least
15 mm under the edge of the tank.
