Fuel

This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your engine requires a mixture of brand-
name gasoline and quality engine oil.
Use regular high-quality unleaded
gasoline with a minimum octane rating
of 89 RON.
If the octane rating of the regular grade
gasoline in your area is lower use
premium unleaded fuel.
Fuel with a lower octane rating may
result in preignition (causing "pinging")
which is accompanied by an increase in
engine temperature. This, in turn,
increases the risk of the piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines etc.), but magnesium castings as
well. This could cause running problems
or even damage the engine. For this
reason it is essential that you use only
high-quality fuels!
Use only STIHL Low-Smoke two-stroke
engine oil or an equivalent engine oil for
air-cooled engines.
We recommend STIHL Low-Smoke
50:1 two-stroke engine oil since it is
specially formulated for use in STIHL
engines.
Do not use BIA or TCW (two-stroke
water cooled) mix oils.
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.
