Fuel
CAUTION:
This saw is powered by mineral-oil products (gasoline
(petrol) and oil).
Be especially careful when handling gasoline (petrol).
Avoid all flame or fire. Do not smoke (explosion hazard).
Fuel mixture
The engine of the chain saw is a high-efficiency 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 9 ROZ. In case no such fuel is available,
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.
For lubricating the engine use a two-stroke engine oil (quality
grade: JASO FC or ISO EGD), which is added to the fuel. The
engine has been designed for use of DOLMAR High Perform-
ance 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 emission of exhaust gases
are ensured. DOLMAR High Performance two-stroke engine
oil is available in the following sizes:
2.6 oz order number 986 00 00
6.4 oz order number 986 00 0
In case DOLMAR High Performance two-stroke engine oil is not
available, it is recommended to use a mixture ratio of 40:1 with
other two-stroke engine oils, as otherwise optimum operation
of the engine cannot be guaranteed.
The correct mixture ratio:
when using DOLMAR High Performance two-stroke
50:1
engine oil, i. e. mix 50 parts gasoline with 1 part oil.
when using other two-stroke engine oils, i. e. mix 40
40:1
parts gasoline with  part oil.
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.
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 environ-
ment and clog the exhaust channel in the cylinder as well
as the muffler. In addition, fuel consumption will rise and
performance will decrease.
Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
flung 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 00% bio-degradable. BIOTOP has been
granted the "blue angel" (Blauer Umweltschutz-Engel) for being
particularly environment-friendly (RAL UZ 48).

The Storage of Fuel
Fuels have a limited storage life. Fuel and fuel mixtures
age through evaporation, especially at high temperatures.
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.
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!
BIOTOP chain oil is available in the following sizes:
 l order number 980 008 20
5 l order number 980 008 2
20 l order number 980 008 23
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).
