Air Filter

The engine air filter consists of a cyclone filter and a fine filter.

Air is drawn in through the screen (1) on the cyclone filter and coarser pollutants collect in the container (2).

The fine filter, consisting of a foam rubber pre-filter and a paper filter cartridge, is located under the cowling

(3). The cowling and the cyclone filter can be removed by removing the wing nut (4).

See Replacing the Air Filter in the Maintenance section for cleaning instructions.

Running the machine with a dirty air filter will cause the engine to run on partial choke and show the same symptoms as a closed choke described above. It can also be difficult to start.

Spark Plug

The engine spark plug is hidden under the ignition cable boot. When performing service, it is important that the engine cannot start accidentally. For this reason, always remove the ignition cable boot from the spark plug. To avoid pulling the cable, the cable boot is equipped with a special handle; see the illustration. See Technical Data for replacement specifications.

Muffler

WARNING!

The engine and the exhaust system, become very hot during operation.

Risk for burns if touched.

Allow engine and exhaust system to cool at least two (2) minutes before refueling

The engine muffler is equipped with a heat protective cowling but still becomes hot when the engine is running. Avoid touching the muffler when it is warm. There is a risk for burns.
