!
Do not clean the filter element (4)
with gasoline or high temperature
liquid.
If the primary element is stained heavily, replace
it soon. At this time, replace the secondary

The secondary element should be removed only
if it is to be replaced.
To protect the engine, do not remove the
secondary element in servicing the primary

Make sure the hooking clip for the element is
tight enough. If it is loose, dust and dirt may be
sucked in wearing down the cylinder liner and
piston ring earlier and thereby resulting in poor
power output.
Do not overservice the air cleaner element.
Overservicing may cause dirt to enter the
engine causing premature wear. Use the dust
indicator as a guide on when to service.
1)
Open the hooking clip.
2)
Remove the filter cover (2) and screw off
the filter element (4).
3) Filter element (4): For slight contamination,
purge with dry compressed air (maximum
205 Kpa) from inside to outside for cleaning
(general cleaning times are no more than 5
times);
Replace it in case of serious contamination.
