The carburettor governs the engine’s speed via the 
throttle control. Air and fuel are mixed in the 
carburettor.

•

Setting the carburettor involves adapting the engine to 
suit local conditions, e.g. climate, altitude and the 
petrol.

The basic carburettor settings are adjusted during testing 
at the factory.

CAUTION!  For optimum adjustment of the carburettor, 
contact a qualified dealer/service workshop that has a 
revolution counter at their disposal. 

Check that the air filter is clean. When the idle speed is 
correct, the cutting attachment should not rotate. If 
adjustment is required, close (turn clockwise) the idle 
adjustment screw T, with the engine running, until the 
cutting attachment starts to rotate. Open (turn 
anticlockwise) the screw until the cutting attachment 
stops. The idle speed is correctly set when the engine 
runs smoothly in all positions, and there is a clear margin 
to the speed at which the cutting attachment starts to 
rotate.

CAUTION!  Some mufflers are fitted with a catalytic 
converter. See chapter on Technical data to see whether 
your machine is fitted with a catalytic converter.

The muffler is designed to reduce the noise level and to 
direct the exhaust gases away from the operator. The 
exhaust gases are hot and can contain sparks, which may 
cause fire if directed against dry and combustible 
material.

The muffler on your machine is equipped with a spark 
arrestor mesh, this should be cleaned regularly. A blocked 
mesh will cause the engine to overheat and may lead to 
serious damage.

CAUTION!  Never use a machine with a defective muffler.
