Carburettor

Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
Function
The carburettor governs the engine speed via the throttle. Air
and fuel are mixed in the carburettor.

Needles
The carburettor is equipped with fixed needles to ensure the
machine always receives the correct mixture of fuel and air.
When the engine lacks power or accelerates poorly, do the
following:
• Check the air filter and replace if necessary.
• When this does not help, contact an authorised service
workshop.
Fine adjustment of the idle speed T

Adjust the idle speed using the T screw. If adjustment is
necessary, first turn the idle screw clockwise until the blades
start to rotate. Now turn the screw anticlockwise until the
blades stop rotating. A correctly adjusted idle speed is set
when the engine accelerates without hesitation.
Rec. idle speed: 2500 rpm

cause personal injuries.

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.
