Never let the engine run without the air filter being fitted. A dirty air filter element affects the
engine performance, increase fuel consumption and makes it difficult to start. If you notice a
loss of engine power, check the air filter. You MUST make sure that the housing is free of
dust and debris DO NOT allow any dust or debris to enter the carburetor.
11.2
Remove the air filter cover by unscrewing the air filter cover wingnut in an anti-clockwise
direction, carefully remove the cover.
11.3
Once the air filter cover has been removed you can undo the air filter wingnut.
Undo the air filter wingnut and remove the Paper/Foam filter element. If it is damaged replace
it. Otherwise tap the filter to remove dust particles. Blow the remaining debris from the filter
using a low pressure airline. Blow from inside the filter outwards. Wash the foam part in
detergent and allow to dry. To reinstate the filter assembly reverse the above process.
