1. Draining the Oil Sump. Discharge the used
oil
through
the sump
drain
hose
(attached
to
the front
of

en!iine)
while the engine is
warm.
Drain
the used

completely,
replace the hose

THE
OIL
INTO
A
SUITABLE
CONTAINER
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-
petent"
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-
siehon
valve.
2.
Replacement
of
the Oil Filter. When removing the
u~
oil filter, you
may
find
it
helpful and cleaner
to
punch a
hole in the upper and lower portion
of
tbe 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

Fi16ng
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
additionalo_it.

that there

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,
cold
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.
