A
CAUTION:
Prolonged
cranking
intervals
without
the
engine
starting
can
result
in
the
engine
exhaust
system
filling
with
raw
water.
This
may
happen
because
the
pump
is
pumping
raw
water
through
the
raw
water
COOling
system
during
cranking.
This
raw
water
can
enter
the
engine's
cylinders
by
way
of
the
exhaust
manifold
once
the
exhaust
system
fills.
Prevent
this
from
happening
by
closing

NOTE:
Never attempt
to

NOTE:
Some unstable running may occur
in

the
operating
temperature
of

the engine.
When
the
engine
is
running and the PREHEAT switch
is
depressed, a charging
load on the
DC alternator will
be
discernible.
STARTING
UNDER
COLD
CONDITIONS
Make
certain
the
lubricating
oil
conforms
with
the
ratings
for
the
prevailing
temperature.
Check
the
table
on
the
engine
oil
section
of
this
manual.
The
battery
should
be
fully
charged
to
minimize
voltage
drop.
Use
a
sufficient
amount
of
preheat
to
aid
in
starting.
See
the
Temperature/Preheat
chart
elsewhere
in
this
section.
STOPPING
PROCEDURE
To
stop
the
engine,
bring
the
throttle
to
an
idle
position
and
place
the
transmission
in
neutral.
Allow
the
engine
to
idle
for
a
few
moments
to
stabilize
temperatures.
Pull
the
STOP
lever
to
shut
down
the
engine.
Then
tum

(12
o'clock).1fthe key switch is left
ON,
the
battery will
discharge.
An engine alarm buzzer
is
provided
to
warn
the
operator
of
this
condition (Key Switch
ON).
The
best method
of
