Carburetor

Always wear approved protective gloves.
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
Basic setting
• The basic carburetor settings are adjusted during
testing at the factory. The basic setting is richer than
the optimal setting and should be maintained for the
first few hours the machine is in use. The carburettor
should then be finely adjusted. Fine adjustment
should be carried out by a skilled technician.
CAUTION! If the cutting attachment rotates when the
engine is idling the idle adjustment screw T should be
turned anti-clockwise until the cutting attachment stops.
Adjustment of the idle speed
Adjust the idle speed using the idle adjustment screw T, if
it is necessary to readjust. First turn the idle adjustment
screw T clockwise until the cutting attachment starts to
rotate. Then turn the screw counter clockwise until the
cutting attachment stops. The idle speed is correctly
adjusted when the engine will run smoothly in every
position. The idle speed should also be well below 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.
