Use only STIHL two-stroke engine oil or 
equivalent branded two-stroke air-
cooled engine oils with the classification 
TC for mixing. 
We recommend  STIHL 50:1 two-stroke 
engine oil since it is specially formulated 
for use in STlHL engines.
Do not use BIA or TCW (two-stroke 
water cooled) mix oils.
Use only STIHL 50:1 heavy-duty 
engine oil or equivalent quality two 
stroke engine oils for the fuel mix in 
models with a catalytic converter.
Take care when handling gasoline. 
Avoid direct contact with the skin and 
avoid inhaling fuel vapour.
The canister should be kept tightly 
closed in order to avoid any moisture 
getting into the mixture.
The fuel tank and the canister in which 
fuel mix is stored should be cleaned 
from time to time.
Fuel mix ages
Only mix sufficient fuel for a few days 
work, not to exceed 3 months of storage. 
Store in approved safety fuel-canisters 
only. When mixing, pour oil into the 
canister first, and then add gasoline. 
Dispose empty mixing-oil canisters only 
at authorized disposal locations.
Before fueling, clean the filler cap and 
the area around it to ensure that no dirt 
falls into the tank.
Always thoroughly shake the mixture in 
the canister before fueling your 
machine.
In order to reduce the risk of burns 
or other personal injury from 
escaping gas vapor and fumes, 
remove the fuel filler cap carefully 
so as to allow any pressure build-up 
in the tank to release slowly.
After fueling, tighten fuel cap as 
securely as possible by hand.
