1. Draining the Oil Sump
Discharge the old oil through the sump drain hose (at-
tached at the front of the engine) while the engine
is
still
warm. Drain the old oil completely, replace the hose in
its bracket, and replace the end cap securely.
Always observe the old oil as it
is
removed. A yellow/gray
emulsion indicates the presence
of
water in the oil. Al-
though this condition is rare, it does require prompt at-
tention
to
prevent serious damage. Call a competent
mechanic should water be present in the oil. Sea water
present in the oil can be the result of a fault in the exhaust
system attached
to
the engine, and/or water siphoning
through the sea water cooling circuit into the exhaust,
filling it up into the engine (refer
to
the exhaust illustra-
tions on pages
21
and 23).

Replacement of the
Oil
Filter
When removing the used oil filter, you may find it helpful
and cleaner
to
punch a hole in the upper and lower por-
tion
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 filter wrench should be helpful in remov-
ing the old oil filter. Place some paper towels and a plas-
tic bag around the filter 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
generator's 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 rubber sealing gas-
ket remains sealed against the engine block, gently
remove it. The replaceable cartridge-type oil filter re-
quires
no
cleaning inside, so
IT
may be properly disposed
of.
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 gas-

ket on the oil filter. Screw the filter onto the threaded oil filter stub, and then tighten the filter firmly
by
hand
NOTE: Generic filters are not recommended, as the material standards or diameters of im-
portant items
on
generic parts might be entirely different from genuine parts. Immediately
after an oil filter change and oil fill, run the engine
to
make sure the oil pressure is normal and
that there are
no
oil leaks around the new oil filter.
