CAUTION:
This saw is powered by petroleum products
(gasoline (petrol) and oil).
Be especially careful when handling gasoline (petrol).
Do not smoke. Keep tool well away from open flames, spark,
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 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-L-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 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 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 (qual-
ity grade JASO FC or ISO-L-EGD), i. e. mix 50 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.
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 consu-
med 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!

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).
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).
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.
