Rotate the blower tube in the direction of the arrow and then pull it out. This engine is certified to operate on unleaded gasoline and with the mix ratio 50:1. Your two-stroke engine requires a mixture of brand-name gasoline and quality two-stroke engine oil with the classification TC. Use regular branded 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. 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 aircooled engine oils with the classification TC for mixing. 10 BG 46

:
Push nozzle (
4
) as onto the blower
tube (
1
) as far as lug (
5
),
position
a
(long) or position
b
(short), and
rotate it in the direction of the arrow
to lock in position.
Removing blower tube
:
Use a suitable tool to lift the
tab (
6
) on the fan housing stub (
3
).
Rotate the blower tube in the
direction of the arrow and then pull it
out.
This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your two-stroke engine requires a
mixture of brand-name gasoline and
quality two-stroke engine oil with the
classification TC.
Use regular branded 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.
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.
