Cleaning the air filter *
It is very important for the engine's life expectancy to clean the air filter
regularly.
To clean the air filter, remove screws
1 and the filter box cover. Detach
retaining clip

from the filter box.
Remove the air filter from the filter holder and wash thoroughly in special
cleaning fluid. Products required for a professional maintenance of the air
filter are available from TWIN AIR. Press out the water from the air filter –
but do not wring – and allow the filter to dry. Lubricate the dry air filter
thoroughly with high-grade filter oil, rubbing to coat the entire filter
surface.
Clean the filter box and cover and check the carburetor connection boot for
damage.
Mount the air filter on the filter holder, position in the filter box (make sure
to center) and fix with the retaining clip. Check whether the air filter is
positioned correctly and mount the filter box cover.
