Air filter cleaning and replacement
A dirty air filter will limit the flow of air towards the carburettor and reduce engine performance. If the
engine is used in very dusty places, the air filter must be cleaned more frequently than specified in the
general maintenance chart.
To CHECK and CLEAN the air filter, first remove the screws from the engine casing (1) then remove
the air filter cover and inspect the filter elements.
To CLEAN (see figure below):
1)
remove the nut from the filter cover and then remove the cover
2)
remove the wing nut from the air filter and remove the filter
3)
remove the foam filter from the paper filter
4)
Inspect both filter elements and replace them if damaged. The paper element must always be
replaced every YEAR or after every 300 HOURS SERVICE.
5)
Clean the air filter elements if they must be reused.
a.
Paper element
: tap the filter element several times on a hard surface to remove dust, or blow
compressed air from the inside of the filter element. DO NOT USE BRUSHES for cleaning as
dust could penetrate into the fibres.
b.
Foam element
: clean in warm soapy water, rinse and allow to dry perfectly. Alternatively, use
a non-flammable solvent and allow to dry. Immerse the filter in clean engine oil, and then
squeeze to remove the excess oil.
6)
Clean the dirt from inside the filter housing and cover using a damp cloth. Prevent dirt from
penetrating into the air duct that leads to the carburettor.
7)
Place the foam filter element on the paper filter element, then fit the assembled filter back in
place. Make sure that the gasket is in position under the air filter, and then fully tighten the wing
nut of the air filter.
8)
Fit the air filter cover back in place and fully tighten the wing nut.
