Carburetor
General
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions. After the engine has used 8-10 tanks of fuel the
engine will be run-in. To ensure that it continues to run at peak
performance and to minimise harmful exhaust emissions
after the running-in period, ask your dealer/service workshop
(who will have a rev counter at their disposal) to adjust your
carburettor.
The carburettor governs the engine speed via the throttle. Air
and fuel are mixed in the carburettor.
High speed jet
The carburetor is equipped with fixed H-jet to ensure the
engine always receives the correct fuel air mixture. If 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.
Adjusting low speed jet
Apply full throttle a couple of times and check that the saw is
accelerating without hesitation. Basic setting L: 1 1/4 turn
open. If an adjustment is necessary, try to reach the
maximum idle speed, by slowly closing the low speed needle

MAINTENANCE
L clockwise until the engine starves from fuel. Then open
(counter-clockwise) 1/8 of a turn. Check the engine
acceleration.
NOTICE! A too lean adjusted low speed needle (the L-
needle closed too much) results in starting difficulties.
Adjusting the idle speed
!
Start the engine and check the idling setting. When the
carburettor is set correctly the cutting blade should be still
while engine is idling.
• Adjust the idle speed using the T screw. When an
adjustment is necessary, first turn the screw clockwise
until the blade starts to rotate. Now turn the screw anti-
clockwise until the blade stops rotating.
Rec. idle speed: 2700 rpm
Starter
Checking the starter cord
• Loosen the screws that hold the starter against the
crankcase and remove the starter.
L
CAUTION! 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.
