CAUTION:
This saw is powered by petroleum products (gasoline
(petrol) and oil).
Be especially careful when handling gasoline (petrol).
Do not smoke. Do not allow gasoline to come near ames,
sparks or re (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 87 (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 EGD), which
has to be added to the fuel. The engine has been designed for
use of DOLMAR High Performance two-stroke engine oil and a
mixture ratio of ONLY 50:1 to protect the environment. In addition,
a long service life and reliable operation with a minimum emis-
sion of exhaust gases are ensured. DOLMAR High Performance
two-stroke engine oil is available in the following sizes:
2.6 oz order number 986 100 100
6.4 oz order number 986 100 101
In case DOLMAR High Performance two-stroke engine oil is not
available, it is urgently recommended to use a mixture ratio of
50:1 with other synthetic two-stroke engine oils, as otherwise
optimum operation of the engine cannot be guaranteed.
The correct mixture ratio:
50:1 when using DOLMAR High Performance two-stroke
engine oil, i. e. mix 50 parts gasoline with 1 part oil.
50:1
when using other synthetic two-stroke engine oils (quality
grade JASO FC or ISO EGD), i. e. mix 50 parts gasoline
with 1 part oil.
NOTE:
For preparing the fuel-oil mixture rst mix the entire oil quantity
with half of the fuel required, then add the remaining fuel. Shake
the mixture thoroughly before pouring it into the tank.
It is not wise to add more engine oil than specied to ensure
safe operation. This will only result in a higher production of
+
combustion residues which will pollute the environ-
ment and clog the exhaust channel in the cylinder
as well as the mufer. In addition, fuel consumption
will rise and performance will decrease.
Storage:
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 consumed over the next
few months. At high temperatures, once fuel has been
mixed it should be used up in 6-8 weeks.
Use only approved and marked containers for
transport and storage. Store fuel only in dry, cool
and 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 immedi-
ately!

Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
ung off the chain too quickly.
We recommend the use of chain oil which is bio-degradable in
order to protect the environment. The use of bio-degradable oil
may even be required by local regulations.
The chain oil BIOTOP sold by DOLMAR is made of special
vegetable oils and is 100% bio-degradable. BIOTOP has been
granted the "blue angel" (Blauer Umweltschutz-Engel) for being
particularly environment-friendly (RAL UZ 48).

BIOTOP chain oil is available in the following sizes:
1 l
5 l
20 l
Bio-degradable oil is stable only for a limited period of
time. It should be used within 2 years from the date of
manufacture (printed on the container).
