4. Unnecessary
and improper
cleaning of the element
may con-
tribute to introducing dust
into the
engine.
5.
If
the
filter element has been
washed,
it
must be completely dry
before it is reused.
6. Check all air
intake
hoses
for tightness. Replace hoses which
are cracked or appear question-
able.

placement filter elements.
To clean the element, proceed
as
fol-
lows:
1. Turn the knurled
knob counterclock-
wise
and
remove the holding
bracket. Then
withdraw the filter
element.
2. Use a
clean
damp cloth
and care-
fully wipe the inside
of
the housing and the
element retaining bracket
to remove any dust
or
foreign matter present. Make
sure
rub-
ber unloading
valve is completely
open and
clean.
3. Determine
if
air
cleaner element is
still
serviceable
and may be cleaned and
reused.
MAKE
SURE THE
ELEMENT IS
IN GOOD PHYSICAL
CONDITION
BEFORE
CONSIDERING CLEANING IT.
If
rubber
seal on
end of
element
is
damaged, or
if
metal canister is dented
or
damaged, the el-
ement must be replaced
regardless of
how
old it is or how many times it has
been
cleaned.
4. Clean the outer element. Use com-
pressed air to back-flow
element.
This pre-
liminary cleaning will remove the loose dust,
making washing easier.
Prepare solution (MF 1900 726 Ml) ac-
cording to directions on the carton.
Soak element in solution for 4 hours
,
re-
taining a temperature of 120° to 1500 F
.
for
most effective cleaning.
Agitate element, then rinse
both
inside
and outside surfaces of element
with
clean
water from a hose.
Continue until
drain
water is clear.
Inspect
element for pin holes, pleat
dam-
age or ruptures that may have
occurred
be-
cause of careless handling.
NITTE: To avoid any operating de-
lay while the dirty element
is
being
washed and
dried, it is recom-
mended that a spare element be
kept
on
hand as an immediate re-
placement part.
5. After cleaning, place a light bulb
in-
side
the element
and carefully check the
element for ruptures or other damage. For
best results, do this
in
a darkened area
0
Inspection
of the element on the outside will
then disclose
any small holes or major rup-
tures.
ANY HOLE IN
THE FILTER ELE-
MENT; EVEN THE
SMALLEST; WILL AL-
LOW
DUST
TO PASS
INTO
THE ENGINE
AND CAUSE
INCREASED
ENGINE WEAR.

then
install
the holding bracket
and tighten
the knurled knob clockwise by
