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! Gasoline which contens alcohol should not used in
DOLMAR products.
For engine lubrication use a two-stroke engine oil (API-TC
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 emis-
sions.
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
Use a mixture ratio of 40:1 should DOLMAR high-performance
oil not be available. Otherwise reliable operation cannot be
guaranteed.
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, muffler and the spark arrester screen. Furthermore
fuel consumption will increase and performance will fall.

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, aller-
gic 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!

- 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.
