Winter Use - Husqvarna 555FX Operator's Manual

spark plug should be replaced after about a month in
operation or earlier if necessary.
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.

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 utilising the
heat from the engine.
There is a special winter kit available when using the
machine in cold and/or snowy conditions, this includes the
following:

• a special air filter cover without air intake (A)
• a cover for the filter holder (B)
• a cover for the starter housing (C)
• a special wear guard with an air duct (D) that routes
the hot air from the muffler to the carburettor
• a special air filter with a coarser mesh size (E)
