”Turbo Air Cleaning” 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.

•Preheat the intake air to the carburetor by using the heat from the cylinder.

Temperature 0°C (32°F) or colder:

The cylinder cover is designed so it can be adjusted for running in cold weather. Remove the plastic in the marked circle, so that preheated air from the cylinder can pass into the carburettor space preventing icing of the air filter, etc.

B

For temperatures below -5°C (23°F) and/or in snow conditions there is also:

•a special cover (A) for the starter housing

A

This reduces the flow of cooling air and prevents large amounts of snow from being sucked into the carburettor space.

IMPORTANT! If the temperature rises above -5 °C (23°F) or 0 °C (32°F) respectively the machine MUST be restored to its normal set-up. The winter plug (B) is fitted in the empty circle on the cylinder cover. Otherwise there is a risk of overheating, resulting in severe damage to the engine.
