CLEANING
AND
INSPECTION
The air cleaner is equipped with a restriction
gauge
(A)
which signals red when the primary filter
element requires cleaning. Check restriction gauge
~
with engine running
at
full speed. Never clean
filter element unless restriction gauge signals red.
Excessive cleaning will shorten element life. After
cleaning, re-set restriction gauge
by
pushing
button on
top
of
gauge.
IMPORTANT
: The air cleaner is a dual element
type. Clean the primary (outer) element only. Do
not attempt
to
clean the secondary (inner)
element. If there is visible dirt on the secondary
element, replace both primary and secondary
elements. See "Filter Elements - Replacement" for
normal change interval.
To clean air filter element:
1.
Remove element from air cleaner canister.
2.
Clean inside
of
canister and cover with a cloth.
3.
Inspect element as follows:
- Hold a bright light (8) inside element and
check carefully for holes. Discard any element
which shows the slightest hole.
-Be sure outer screen
(C)
is not dented.
