Stihl TS 500i Manual De Instrucciones página 39

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 (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.

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.
STIHL MotoMix
STIHL recommends the use of STIHL
MotoMix. STIHL MotoMix has a high
octane rating and ensures that you
always use the right gasoline/oil mix
ratio. It also contains no ethanol.
STIHL MotoMix uses STIHL HP Ultra
two-stroke engine oil suited for high
performance engines.
If not using MotoMix, use only STIHL
two-stroke engine oil or equivalent high-
quality two-stroke engine oils that are
designed for use in air cooled two-cycle
engines.
Do not use BIA or TCW rated (two-
stroke water cooled) mix oils or other
mix oils that state they are for use in both
water cooled and air cooled engines
(e.g., outboard motors, snowmobiles,
chain saws, mopeds, etc.).
WARNING
Take care when handling gasoline. It is
extremely flammable. Avoid direct
contact with the skin and avoid inhaling
fuel vapor. Transport and store fuel only
in approved containers. When filling at
the pump, remove the fuel container
from your vehicle and place it on the
ground before filling. To reduce the risk
of sparks from static discharge and
resulting fire and/or explosion, do not fill
fuel containers that are sitting in or on a
vehicle or trailer.
The container should be kept tightly
closed in order to limit the amount of
moisture that gets into the mixture.
The machine's fuel tank should be
cleaned as necessary.
