Clean the fuel tank every 100 hours of operation. For this, the tank should be taken from the holder
and rinsed. The fuel filter should periodically be cleaned.
If the engine shall be stored for long periods of time, the fuel tank shall be completely emptied and the
carburettor emptied on his discharge screw. The engine oil should be discharged when the engine is
hot, but switched off. Then re-fill new oil. The engine should be completely cleaned of dirt from the out -
side. The air filter and spark plug should be checked again and replaced or cleaned if necessary. The
combustion chamber should be filled with some motor oil when the spark plug is unscrewed so that
the combustion chamber is not oxidized. After that, the engine may be stored in a dry storage place.
