Gasoline
Use only high-quality brand-name
gasoline with a minimum octane rating
of 90 – leaded or unleaded.
If your machine is equipped with a
catalytic converter, you must use
unleaded gasoline.
A few tankfuls of leaded gasoline
will greatly reduce the efficiency of
the catalytic converter.
Engine Oil
Use only quality two-stroke engine oil.
We recommend STIHL two-stroke
engine oil since it is specially
formulated for use in STlHL engines
and guarantees a long engine life.
If STIHL two-stroke engine oil is not
available, use only quality two-stroke oil
designed for use in air cooled engines.
Do not use oils designed for water
cooled engines or engines with a
separate lubricating system (e.g.
conventional four-stroke engines).
Use only STIHL 50:1 two-stroke
engine oil for the fuel mix in models with
a catalytic converter.
Mix Ratio
STIHL 50:1 two-stroke engine oil:
50 parts gasoline to 1 part oil
Other high-quality two-stroke engine
oils:
25 parts gasoline to 1 part oil
Examples
: Use a canister approved for storing
fuel. Pour oil into the canister first,
then add gasoline and mix
thoroughly.
Storing Fuel
Store fuel only in approved safety-type
fuel canisters in a dry, cool and safe
location protected from light and the sun.
Fuel mix ages:
Only mix sufficient fuel for a few weeks
work. Do not store fuel mix for longer
than 3 months.
Exposure to light, the sun, low or high
temperatures can quickly make the fuel
mix unusable.
: Thoroughly shake the mixture in the
canister before fueling your
machine.
Pressure may build up in the
canister – open it carefully.
: Clean the fuel tank and canister
from time to time.
Dispose of remaining fuel and
cleaning fluid properly in
accordance with local regulations
and environment requirements.
