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 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.
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 HP 100 high-performance two-stroke engine oil and a
mixture ratio of only 100:1 to protect the environment. In addition, a
long service life and reliable operation with a minimum emission of
exhaust gases are ensured.
DOLMAR HP 100 high-performance two-stroke engine oil is avail-
able in the following sizes:
0,5 l order number 980 008 109
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
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 two-stroke engine oils, as otherwise optimum operation
of the engine cannot be guaranteed.
Caution: Do not use ready-mixed fuel from petrol stati-
ons.
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.
100:1 when using DOLMAR HP 100 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 Þ rst mix the entire oil quantity
with half of the fuel required, then add the remaining fuel. Thoroughly
shake the mixture before Þ lling it into the chain saw tank.
It is not wise to add more engine oil than speciÞ ed 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 mufß er.
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 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!

Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
ß 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 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 ß ush 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, Þ ll 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.
