Gasoline
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 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 mixtu-
res 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 con-
sumed over the next few months.
Store fuel safely in a dry place in approved con-
tainers only.
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!

PUTTING INTO OPERATION
Fuel
CAUTION:
This trimmer 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 hedge trimmer 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.
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 ope-
ration 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
In case DOLMAR high-performance two-stroke engine oil is not
available, it is urgently 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.
Caution: Do not use ready-mixed fuel from petrol
stations.
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.
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 quan-
tity with half of the fuel required, then add the remaining fuel.
Thoroughly shake the mixture before filling it into the hedge
trimmer tank.
