!
Stop engine.
NOTICE − Do not run engine without air
cleaner or with dirty element. Engine
damage caused by using a damaged ele-
ment is not covered by the warranty.
.
The air cleaner primary element can
be cleaned but the dirt holding capac-
ity of the filter is reduced with each
cleaning. The chance of dirt reaching
the clean side of the filter while clean-
ing and the possibility of filter damage
makes cleaning a risk. Consider the
risk of unwarrantable equipment
damage when determining whether
to clean or replace the primary ele-
ment.
If you decide to clean the primary ele-
ment, we strongly recommend instal-
ling an optional safety element to pro-
vide additional engine protection.
Never clean a safety element. Re-
place the safety element after servic-
ing the primary element three times.
