CHEROKEE 180 SECTION VI
FUEL AND OIL REQUIREMENTS
Aviation Grade 100/130 Octane
(minimum)
fuel
must
be
used
in
the Cherokee. Because the use of
lower grades
can
cause serious
damage
in
a very short
period
of time,
the
engine warranty
is invalidated
by
such use.
The oil capacity
of
the Lycoming O-360-A4A
is
8
quarts,
and
the
minimum safe
quantity is
2
quarts.
It
is
recommended
that
the oil and
oil
filter
be
changed every
50
hours,
or sooner under unfavorable
conditions.
The following
grades
are recommended
for the
specific
temperatures:
Temperatures above
60°F
S.A.E.
50
Temperatures between
30°
and
90°F
S.A.E.
40
Temperatures
between
0°
and
70°F
S.A.E. 30
Temperatures
below
10°F
S.A.E. 20
FUEL SYSTEM
The
fuel
screen
in
the strainer will
require
cleaning every
50 hour
inspection.
The
strainer,
located ahead of
the
firewall, is
accessible
for
cleaning
by
removal
of
the lower
cowl.
When the
strainer
is
reassembled
after
cleaning, a small amount
of
grease
applied
to
the
gasket
will
facilitate
assembly.
CARE OF AIR FILTER
The
carburetor
air filter
must
be
cleaned at least
once
every fifty
hours. Under extremely
adverse
conditions of operation
it
may
be
necessary
to clean
the
filter daily. Extra filters
are
inexpensive
and
a
spare
should
be kept
on
hand and
used as a
rapid replacement.
The filter manufacturer recommends
that
the
filter be
tapped
gently
to
remove
dirt particles.
Do
not
blow
out
with
compressed air.
