17.5.2 Brake cable adjustment
Cleaning the air filter
To clean the air filter, proceed as follows:
1. Press the clamps and remove the air filter cover.
2. Remove the filter.
3. Check filter and foam element and replace if damaged.
4. Clean the filter by tapping it several times on a hard surface to remove dirt, or blow
compressed air from the inside through the air filter.
5. Never attempt to brush off dirt; brushing forces dirt into the fibers.
6. Remove dirt from the inside of the air filter base and cover with a damp cloth.
Ensure that no dirt enters the air duct leading to the carburetor.
7. Remount the filter and cover.
Cleaning / Replacing the Spark Plug
For error-free operation, the contact surface of the candle in the cylinder head and the sealing
ring of the candle must be clean and free of residues.

If the engine is operated with or without a damaged air filter, dirt will get into
the engine, resulting in rapid engine wear.
A loose spark plug can overheat and damage the engine. Tightening the spark
plug too much can damage the thread in the cylinder head.
If the brake lever is loose, tighten the brake
cable by turning it (see picture on the left).
