aVoID SkIn anD EyE ConTaCT!
Utmost care is required when handling fuel. Fuel may contain
substances similar to solvents. Refuel either in a well ventilated
room or outdoors. Do not inhale fuel vapours. Fuel vapours are
poisonous and can be hazardous to your health. Avoid eye and
skin contact with fuels and mineral oils. 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!
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.

foLLow THE SafETy PrECaUTIonS!
Be careful and cautious when handling fuels.
The engine must be switched off!
refuelling
The brushcutter is powered by a high-performance two-stroke
engine. The engine runs on a mixture of gasoline and two-stroke
engine oil.
The engine was designed for regular lead-free gasoline with
an octane number of at least 91 ROZ. If this is not available,
higher-octane gasoline may be used. This will not damage the
engine, but may impair engine performance.
A similar situation will arise from the use of leaded fuel. To obtain
optimum engine operation and to protect your health and
the environment, only unleaded fuel should be used!
For engine lubrication use a two-stroke engine oil (JASO FC
or ISO EGD quality grade). Add it to the fuel during refuelling.
The engine was designed for use with a high performance
two-stroke oil sold by DOLMAR, with a mixture ratio of 50:1.
This will ensure long engine life and reliable operation with low
exhaust emissions.
DOLMAR high-performance two-stroke engine oil is available
in two different sizes:
1 liter part no. 980 008 107
100 ml part no. 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 sta-
tions.
Preparation of the correct mixture ratio:
50:1 When using DOLMAR high-performance two-stroke oil,
i.e. 50 parts gasoline /1 part oil.
40:1 When using other brands, i.e. 40 parts gasoline / 1 part
oil.
note:
When preparing the fuel mixture, always first mix the entire
oil quantity with half of the gasoline, and then add the rest of
the gasoline. Shake the mixture well before putting in the fuel
tank.
It is not wise to add more oil to the mixture than specified,
even if this may seem safer for the engine. More oil only leads
to increased combustion residues, which not only pollute the
environment, but are also bad for the cylinder exhaust channel
and the muffler. Furthermore fuel consumption will increase and
performance will fall.

- Thoroughly clean around the tank cap (B/1) so that no dirt
can enter the fuel tank.
- Before refuelling the brushcutter make sure it is on its
side in a stabile position.
- Unscrew the tank cap (B/2) and carefully fill in the fuel mixture
up to the lower edge of the filler neck. Fill the tank carefully,
making sure not to spill any fuel.
- Tightly screw on the cap.
Clean screw cap and tank after refuelling.
