Air Injection" Centrifugal Cleaning; Winter Use - Husqvarna 445 Manual De Instrucciones

"Air Injection" centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburetor passes through the starter. Dirt and dust is
pushed out by the cooling fan.
IMPORTANT! In order to maintain operation of the
centrifugal cleaning system it must be regularly
maintained. Clean the air intake to the starter, the fins on
the flywheel, the space around the flywheel, inlet pipe and
carburetor compartment.

Winter use

Running problems can occur when using the machine in
the cold and snowy conditions caused by:
• Too low engine temperature.
• Icing of the air filter and carburetor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.

MAINTENANCE
Temperature -5° ° ° ° C (23° ° ° ° F) or colder:
For running the machine in cold weather or powder snow,
a special cover is available, which is mounted on the
starter housing. This reduces the intake of cold air and
prevents large amounts of snow from being sucked in.
CAUTION! If the special winterising kit has been fitted or
any measures have been taken to increase the
temperature these changes must be reversed before the
machine is used in normal temperature conditions.
Otherwise there is a risk of overheating, resulting in
severe damage to the engine.
IMPORTANT! Any maintenance other than that described
in this manual must be carried out by your servicing dealer
(retailer).
