WARNING
Never use two abrasive wheels at the
same time. The uneven wear creates a
risk of breaking and an injury hazard!

Fuel
This engine is certified to operate on
unleaded gasoline and the STIHL two-
stroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of fresh,
high-quality gasoline and two-stroke air
cooled engine oil. Operators who are not
using MotoMix should never use fuel
that has been stored for more than thirty
(30) days.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 ((R+M)/2)
and no more than 10% ethanol content.
NOTICE
Fuel with an octane rating below 89 may
increase engine temperatures. This, in
turn, increases the risk of 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 and
catalytic converters as well. This could
cause running problems or damage the
engine. For this reason STIHL
recommends that you use only MotoMix
or another quality unleaded gasoline.
NOTICE
Gasoline with an ethanol content of
more than 10% can cause running
problems and major damage in engines
and should not be used.
For further details, see
www.STIHLusa.com/ethanol
The ethanol content in gasoline affects
engine speed – it may be necessary to
readjust the carburetor if you use fuels
with different ethanol contents.
WARNING
To reduce the risk of personal injury
from loss of control and/or contact with
the running wheel, do not use your unit
with an incorrect idle adjustment. When
the idle speed is properly adjusted, the
wheel should not move while the
machine is idling.
If your cut-off machine's idle speed is
incorrectly adjusted, have your
authorized STIHL servicing dealer
check your machine and make the
proper adjustments and repairs.
The idle speed and maximum speed of
the engine change if you switch to a fuel
with a much higher or lower ethanol
content.
This problem can be avoided by always
using fuel with the same ethanol
content, which should never exceed
10%.
To ensure the maximum performance of
your STIHL engine, use a fresh, high
quality 2-cycle engine oil. To help your
engine run cleaner and reduce harmful
carbon deposits, STIHL recommends
using STIHL HP Ultra 2-cycle engine oil
or ask your dealer for an equivalent, fully
synthetic 2-cycle engine oil if you are not
using MotoMix.
We recommend using STIHL MotoMix
or a fresh, high quality gasoline of at
least 89 octane and STIHL HP Ultra oil.
