CAUTION: This saw is powered by mineral-oil products
(gasoline (petrol) and oil). Be especially careful when hand-
ling 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 91 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.
Gasoline which contens alcohol should not used in
DOLMAR products.
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-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 emission of exhaust gases are ensured.
DOLMAR high-performance two-stroke engine oil is available
in the following sizes to suit your individual requirements:
1 l order number 980 008 107
100 ml order number 980 008 106
If DOLMAR high-performance two-stroke engine oil is not availa-
ble, we urgently recommended 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:
50:1 when using DOLMAR high-performance two-stroke engi-
ne oil, i. e. mix 50 parts gasoline with 1 part oil.
40:1 when using other two-stroke engine oils, i. e. mix 40 parts
gasoline with 1 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. Shake
the mixture thoroughly before pouring it into the 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
combustion 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.
Therefore fuel and fuel mixtures, which have been stored for too
long, can cause starting problems. Purchase only that amount of
fuel, which will be consumed over the next few months.
Store fuel safely in a dry place in approved containers only.

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 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 order number 980 008 210
5 l order number 980 008 211
20 l order number 980 008 213
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).
Important note on bio-degradable chain oils:
If you are not planning to use the saw again for an extended
period of time, empty the oil tank and put in a small amount of
regular engine oil (SAE 30), and then run the saw for a time.
This is necessary to flush out all remaining bio-degradable oil
from the oil tank, oil-feed system, chain and guide bar, as many
such oils tend to leave sticky residues over time, which can
cause damage to the oil pump or other parts.
The next time you use the saw, fill the tank with BIOTOP chain
oil again.
C
NEVER USE WASTE OIL
Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
Residues in waste oil result in a high degree of wear and tear
at the oil pump and the sawing device.
In case of damage caused by using waste oil or unappropriate
chain oil the product guarantee will be null and void.
Your salesman will inform you about the use of chain oil.
