Winter Use - Husqvarna 343F Operator's Manual

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 carburettor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
• Preheat the intake air to the carburettor by using the heat
from the cylinder.
Temperature 0° ° ° ° C or colder:
The air filter holder is prepared so it can be changed for use
in the cold. Remove the air filter cover and air filter. Turn the
winter cover anticlockwise using a screwdriver so that the
preheated air from the engine can pass inside the carburettor
compartment and prevent, for example, the air filter from icing
up (see figure).
For temperatures below -5°C and/or in snow conditions there
is also:
• a special cover for the starter housing
• a cover for cylinder cover's air inlet should be fitted as
illustrated.
These reduce the cooling air and prevent large amounts of
snow from being sucked into the engine.
IMPORTANT! If the temperature rises above -5°C or 0°C
respectively the machine MUST be restored to its normal set-
up. Otherwise there is a risk of overheating, which can cause
severe engine damage.
IMPORTANT! Any maintenance other than that described in
this manual must be carried out by your servicing dealer
(retailer).
