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.

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)

°°°°C or colder:

Fit the covers for the starter housing and air filter holder 
using the three screws provided as shown in the figure.

Remove the air filter and air filter cover from the machine. 
Fit the air filter and air filter cover supplied with the winter 
kit.

°°°°C or colder:

Dismantle the machine’s wear guard, and fit the wear 
guard from the winter kit as shown in the figure. Pay
