MAINTENANCE
Carburetor
Function
The carburetor governs the engine’s speed via the throttle 
control. Air and fuel are mixed in the carburetor.
Setting the carburettor involves adapting the engine to suit 
local conditions, e.g. climate, altitude and the petrol.
Basic setting
The basic carburetor 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. 
Adjusting the idle speed (T)
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.
Muffler
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.
Cooling system
To keep the working temperature as low as possible the 
machine is equipped with a cooling system.
The cooling system consists of:
1
Air intake on the starter.
2
Fins on the flywheel.
3
Cooling fins on the cylinder.
4
Cylinder cover (directs cold air over the cylinder).
!
WARNING! The complete clutch cover and 
shaft must be fitted before the machine is 
started, otherwise the clutch can come loose 
and cause personal injury.
!
WARNING! If the idle speed cannot be 
adjusted so that the cutting attachment 
stops, contact your dealer/service 
workshop. Do not use the machine until it 
has been correctly adjusted or repaired.
!
WARNING! Mufflers fitted with catalytic 
converters get very hot during use and 
remain so for some time after stopping. This 
also applies at idle speed. Contact can result 
in burns to the skin. Remember the risk of 
fire!
