Cleaning the air filter
CAUTION: Never run the engine without the air filter.
A dirty air filter puts pressure on engine performance, increases fuel consumption, and makes starting more
difficult. If you notice a loss of engine power:
1 Remove the screw on the filter cover and take out the filter.
2 Clean the filter with soap and water. Never use gasoline or benzene!
3 Let the filtered air dry.
4 Put the filter back in place and fasten the filter cover with the screw.
Spark plug maintenance
To ensure the normal operation of the engine, the ignition distance of 0.6 -0.7mm must be
maintained and must be free of carbon deposits. Always carry out the following steps with the
engine switched off:
1. Carefully remove the spark plug connector. Do not pull on the cable but directly on the plug
2. Use the spark plug wrench supplied to unscrew the spark plug
3. Visually check the spark plug for damage and electrode burn-off,
Remove the carbon deposits
4. Check the gap with a feeler gauge and bend the electrode to the correct distance
of 0.6 to 0.7mm
5. Check the spark plug washer and tighten the spark
plug with a torque of 12-15 Nm
6. Fit the ignition cap back onto the spark plug
WARNING
The spark plug must be screwed down
tightly; otherwise, the engine runs hot and is
damaged.
