Fuel - Stihl MS 210 Instruction Manual

English

Fuel

The engine requires a mixture of
gasoline and engine oil.
WARNING
Avoid direct skin contact with and
breathing in of gasoline fumes.
STIHL MotoMix
STIHL recommends using STIHL
MotoMix. This pre-blended fuel is free of
benzene and lead, stands out because
of a high octane rating, and always
provides the proper mixing ratio.
STIHL MotoMix is blended with STIHL
HP Ultra two-stroke engine oil for
maximum engine life.
MotoMix is not available in all markets.
Mixing fuel
NOTICE
Unsuitable fuels or a mixing ratio that
deviates from the specification can lead
to severe engine damage. The engine,
seals, fuel lines and fuel tank may be
damaged if poor quality gasoline or
engine oil is used.
Gasoline
Use only high-quality gasoline with an
octane rating of at least 90 ROC –
leaded or unleaded.
20
Unleaded gasoline must be used in
machines equipped with a catalytic
converter.
NOTICE
Using multiple tankfuls of leaded
gasoline can substantially reduce the
effectiveness of the catalytic converter.
Gasoline with an alcohol component
exceeding 10% can cause impaired
engine performance in engines with
manually adjustable carburetors and
thus should not be used in these
engines.
Engines with M-Tronic deliver full engine
performance using gasoline with an
alcohol component of up to 25% (E25).
Engine oil
Use only high-quality two-stroke engine
oil – ideally STIHL HP, HP Super or
HP Ultra two-stroke engine oil, as they
are specially engineered for STIHL
engines. HP Ultra ensures maximum
performance and engine life.
The engine oils are not available in all
markets.
Only STIHL two-cycle engine oil 1:50
may be used to produce the fuel mixture
for machines with a catalytic converter.
Mixing ratio
for STIHL two-cycle engine oil 1:50;
1:50 = 1 part oil + 50 parts gasoline
MS 210, MS 210 C, MS 230, MS 230 C, MS 250, MS 250 C

Pour oil into an approved safety fuel
N
canister first, then add gasoline and
mix thoroughly
Storing fuel mixture
Store in approved safety fuel canisters
only in a dry, cool and secure place
protected against light and sunlight.
Fuel mixture ages – mix only as much as
needed for a few weeks. Do not store
fuel mixture for longer than
three months. The fuel mixture can
become unusable faster if exposed to
light, sunlight or low or high
temperatures.
Shake the canister containing the
N
fuel mixture thoroughly before
refueling
WARNING
Pressure can build up inside the canister
– open carefully.
The fuel tank and the canister in
N
which fuel mixture is stored should
be cleaned thoroughly from time to
time
