Y Stop engine.
Y Do not run engine without air
cleaner or with dirty element. En-
gine damage caused by using a
damaged element is not covered
by the warranty.
.
The air cleaner primary element can
be cleaned but the dirt holding ca-
pacity of the filter is reduced with
each cleaning. The chance of dirt
reaching the clean side of the filter
while cleaning and the possibility of
filter damage makes cleaning a risk.
Consider the risk of unwarrantable
equipment damage when determin-
ing whether to clean or replace the
primary element.
If you decide to clean the primary
element, we strongly recommend
installing an optional safety element
to provide additional engine protec-
tion. Never clean a safety element.
Replace the safety element after
servicing the primary element three
times.
