Fueling - Stihl MS 171 Instruction Manual

English
Fuel mixture deteriorates with age – mix only as
much as needed for a few weeks. Do not store
fuel mixture for longer than 30 days. The fuel
mixture can become unusable more quickly if
exposed to light, sunlight or low or high tempera‐
tures.
STIHL MotoMix however can be stored for up to
5 years without any problems.
► Shake the canister containing the fuel mixture
thoroughly before refueling
WARNING
Pressure may have built up in the canister –
open it carefully.

mixture is stored should be cleaned thoroughly
from time to time

must be disposed of in accordance with regula‐
tions and without harming the environment!
