10.Air Cleaner Element
A: REPLACEMENT
NOTE:
Do not attempt to clean the air cleaner element.
The filter paper of the element is wetted with a spe-
cial non-inflammable slow-evaporating viscous liq-
uid. 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.
