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.

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.
