English
To meet the requirements of EPA and
CARB we recommend to use STIHL HP
Ultra oil.
Do not use NMMA 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.).
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapor. When filling at
the pump, first remove the container
from your vehicle and place the
container 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 any
moisture that gets into the mixture.
The machine's fuel tank should be
cleaned as necessary.
STIHL MotoMix
STIHL recommends the use of STIHL
MotoMix. STIHL MotoMix has a high
octane rating and ensures that you
always use the right mix ratio.
STIHL MotoMix uses STIHL HP Ultra
two-stroke engine oil suited for high
performance engines.

Fuel mix ages
Only mix sufficient fuel for a few days
work, not to exceed 30 days of storage.
Store in approved fuel-containers only.
When mixing, pour oil into the container
first, and then add gasoline. Close the
container and shake it by hand to ensure
proper mixing of the oil with the fuel.
WARNING
Shaking fuel can cause pressure to build
in the fuel container. To reduce the risk
of fire and severe personal injury or
property damage from fuel spraying,
allow the fuel container to sit for several
minutes before opening. Open the
container slowly to release any residual
pressures. Never open the fuel
container in the vicinity of any ignition
source. Read and follow all warnings
and instructions that accompany your
fuel container.

Fueling
WARNING
Removing the cap on a pressurized fuel
tank can result in gasoline, vapors and
fumes being forcefully sprayed out from
the tank in all directions. The escaping
gasoline, vapors or fumes, sometimes
referred to as fuel spraying or
"geysering," can cause serious personal
injury, including fire and burn injury, or
property damage.
Fuel spraying can occur when the
engine is hot and the tank is opened
while under pressure. It can occur in hot
environments even if the engine has not
been running. Spraying is more likely to
occur when the fuel tank is half full or
more.
Avoid Injuries from Fuel Spraying.
Always follow the fueling instructions in
this manual:
–
Treat every fuel tank as if it is
pressurized, particularly if it is half
full or more.
–
Always allow the chain saw to cool
adequately before attempting to
open the fuel tank or refueling; this
will take longer in hot conditions.
