unleaded gasoline and the STIHL two-
stroke engine oil at a mix ratio of 50:1.

Nylon Line".
Your engine requires a mixture of high-
quality gasoline and quality two-stroke
air cooled engine oil.
All other mowing heads
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 (R+M/2). If
the octane rating of the mid-grade
gasoline in your area is lower, use
premium unleaded fuel.
Refer to the instructions supplied with
the mowing head.
To reduce the risk of injury,
always shut off the engine before
adjusting the mowing line by
hand.

Fuel with a lower octane rating may
increase engine temperatures. This, in
turn, increases the risk of piston seizure
and damage to the engine.

Replacing Nylon Line / Polymer
Blades
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 and
catalytic converters as well. This could
cause running problems or even
damage the engine. For this reason
STIHL recommends that you use only
nationally recognized high-quality
unleaded gasoline!

equivalent high-quality two-stroke
engine oils that are designed for use
only in air cooled two-cycle engines.
Line feed operates only if both lines still
have a minimum length of 1 in (2.5 cm).
If the line is shorter than 1 in (2.5 cm):
We recommend STIHL 50:1 two-stroke
engine oil since it is specially formulated
for use in STlHL engines.

always shut off the engine before
adjusting the mowing line by
hand.
