a . Do not attempt to clean the air cleaner element .
The filter paper of the element is wetted with a
special non- inflammable slow-evaporating viscous
liquid . It is resistant to cold weather and has a long
service life . Dirt adhering to this filter paper forms
porous laminations with the viscous liquid, which
function as a filtration layer to reduce dust penetra-
tion into the filter paper . If this filter paper is
cleaned, the filtration layer thus formed will be lost
along with the viscous liquid .
b. Under extremely dusty conditions, replace it more
frequently.
