Draining the Oil Sump. Discharge the
used
oil
through
the
sump
drain
hose
(attached
to
the
front
of
the
engine)
while the
engine
is
warm.
Drain
the
used
oil
completely,
replace the hose
in
its
bracket,
and
replace
the
end
cap
securely.

Always observe
the
used
oil
as
it
is
removed.
A
yellow/gray
emulsion
indicates
the
presence
of
water
in
the
Oil.
Although this condition is rare,
it
does
require
prompt attention
to
prevent serious damage. Call a
com-
petenf mechanic should water
be
present
in
the oil.
Raw
water present
in
the
oil
can
be
the
result of a fault
in
the
exhaust system
attached
to
the engine and/or a siphoning
of
raw water through the
raw
water cooling circuit
into
the exhaust, filling
the
engine. This problem is often
caused
by
the
poor
location
of
or the lack of an
anti-
siP,ho~
yalve ..
2. Replacement
of
the Oil Filter. When removing
the
~
oil
filter,
you
may
find
it
helpful
and cleaner to punch a
hole in
the
upper
and
lower
portion
of
the old filter
to
drain
the
oil
from
it
into
a container before removing
it.
This helps
to
lessen
spillage. A small style automotive fil-
ter wrench should
be
helpful
in removing the old oil
filter.
NOTE:
Do
not punch this
hole
without first loosening the filter
to make certain it
can
be
removed!
Place some paper
towels
and
a plastic bag around
the
fil-
ter
when
unscrewing
it
to
catch
any
oil left
in
the
filter.
·(oil or
any
other
fluid
on
the
engine reduces the engine's
cooling
ability.
Please
keep your engine clean.) Inspect
the
old oil
filter
as
it
is
removed
to
make
sure that the rubber
sealing gasket
came
off
with
the
old oil
filter.
If
this rub-
ber sealing gasket
remains
sealed
against
the
engine
block, gently
remove
it.
When
installing
the
new
oil
filter
element, wipe the
filter
gasket's sealing
surface
on
the
engine block free
of
oil
and
apply
a thin coat of clean
engine
oil
to
the
rubber gasket
on
the
new
oil
filter.
Screw
the
filter onto
the
threaded
oil
filter
nipple, and
then
tighten
the
filter
firmly
~y
hand.
3. Filling the Oil Sump.
Add
new
oil
through
the
oil filler
cap
on
the
top
of
the
engine or through the
side
oil
fill.
After
refilling,
run
the
generator
for a few moments while
checking
the
engine's
oil
pressure.
Make
sure there is
no
leakage
around
the
new
oil
filter
or from the oil drain
sys-
tem,
and
stop
the
generator.
Then
check the quantity
of
oil
with
the
lube
oil
dipstick.
Fill
to,
but
not
over the
high
mark
on
the
dipstick,
should
the
engine require additional
oil.

Oil
Pressure
The engine's oil pressure,
during
operation, is indicated
by
the
oil
pressure gauge on
the
instrument panel. During
nor-
mal
operation,
the
oil
pressure
will
range
between 35
and
55
psi.
NOTE:A
newly
started,
co~J
engine can
have
an
oil pressure
reading
upwards
of
60
psi.
A warmed engine
can
have
an oil
pressure reading as low
as
35
psi.
These readings will vary
depending
upon the temperature
of
the
engine
and
the load
placed on
the
generator.
