!

and to direct exhaust fumes away from the user.

• Check regularly that the muffler is complete and secured
correctly.

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.
WARNING! Never use a machine without a
muffler, or with a faulty muffler. A damaged
muffler may substantially increase the noise
level and the fire hazard. Keep fire fighting
equipment handy.
The muffler gets very hot during and after
use. This also applies during idling. Be
aware of the fire hazard, especially when
working near flammable substances and/or
vapours.
