Fuels
Caution:
This tool uses petroleum products (gasoline and oil).
Be especially careful when handling gasoline.
Do not smoke. Do not allow gasoline to come near flames,
sparks or fire (explosion hazard).
Fuel mixture
This tool is powered by a high-performance air-cooled two-stroke
engine. It runs on a mixture of gasoline and two-stroke engine
oil.
The engine is designed for unleaded regular gasoline with a
min. octane value of 89 (R+M)/2. In case no such fuel is avail-
able, you can use fuel with a higher octane value. This will not
affect the engine.
In order to obtain an optimum engine output and to protect
your health and the environment use unleaded fuel only.
To lubricate the engine, use a synthetic oil for two-stroke air-
cooled engines (quality grade JASO FC or ISO-L-EGD), which
has to be added to the fuel.
The correct mixture ratio:
50:1
When using DOLMAR High Performance two-stroke
engine oil, i. e. 50 parts gasoline to 1 part oil.
50:1
When using other synthetic two-stroke engine
oil (quality grade JASO FC or ISO-L-EGD), i. e.
50 parts gasoline to 1 part oil.
DOLMAR High Performance two-stroke engine oil (50:1) is
available in the following sizes to suit your individual require-
ments:
2.6 floz.
order number 986 100 100
6.4 floz.
order number 986 100 101
NOTE: For preparing the fuel-oil mixture first mix the entire oil
quantity with half of the fuel required, then add the remaining
fuel. Thoroughly shake the mixture before filling it into the chain
saw tank.
Caution: Open the tank cap carefully, as pressure might have
built up inside!
It is not wise to add more engine oil than specified to ensure
safe operation. This will only result in a higher production
of combus-tion residues which will pollute the environment
and clog the exhaust channel in the cylinder as well as the
muffler. In addition, fuel consumption will rise and perform-
ance will decrease.

The Storage of Fuel
Fuels have a limited storage life. Fuel and fuel mixtures
age through evaporation, especially at high tempera-
tures. Aged fuel and fuel mixtures can cause starting
problems and damage the engine.
Purchase only that amount of fuel, which will be consu-
med over the next few months. At high temperatures,
once fuel has been mixed it should be used up in 6-8
weeks.
Store fuel only in proper containers, in dry, cool,
secure locations!
AVOID SKIN AND EYE CONTACT
Mineral oil products degrease your skin. If your skin
comes in contact with these substances repeatedly and
for an extended period of time, it will desiccate. Various
skin deseases may result. In addition, allergic reactions
are known to occur.
Eyes can be irritated by contact with oil. If oil comes into
your eyes, immediately wash them with clear water. If your
eyes are still irritated, see a doctor immediately!
