Fuel

This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your two-stroke engine requires a
6
mixture of brand-name gasoline and
quality two-stroke engine oil with the
classification TC.
Use regular branded unleaded gasoline
3
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.
Note: Units with a catalytic converter
require unleaded gasoline. The
efficiency of the catalytic converter can
drop more than 50 % if several tankfuls
of leaded gasoline are used.
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
name branded fuels!
Use only STIHL two-stroke engine oil or
equivalent branded two-stroke air-
cooled engine oils with the classification
TC for mixing.
