Note:
The engine is equipped with a device for cold
starting. If the engine will be operated in very cold
conditions, then an extra cold starting aid may be
required. Normally, the engine will be equipped with
the correct type of starting aid for your region of
operation.
These engines are equipped with a glow plug starting
aid in each individual cylinder that heats the intake air
in order to improve starting.

Stopping
Stop
the
engine
according
to
the
procedure
in
the
Operation
and
Maintenance
Manual,
“Engine
Stopping
(Operation
Section)”
in
order
to
avoid
overheating
of
the
engine
and
accelerated
wear
of
the
engine
components.
Use
the
Emergency
Stop
Button
(if
equipped)
ONLY
in
an
emergency
situation.
Do
not
use
the
Emergency
Stop
Button
for
normal
engine
stopping.
After
an
emergency
stop,
DO
NOT
start
the
engine
until
the
problem
that
caused
the
emergency
stop
has
been
corrected.
Stop
the
engine
if
an
overspeed
condition
occurs
during
the
initial
start-up
of
a
new
engine
or
an
engine
that
has
been
overhauled.
To

Electrical
System
Never
disconnect
any
charging
unit
circuit
or
battery
circuit
cable
from
the
battery
when
the
charging
unit
is
operating.
A
spark
can
cause
the
combustible
gases
that
are
produced
by
some
batteries
to
ignite.
To
help
prevent
sparks
from
igniting
combustible
gases
that
are
produced
by
some
batteries,
the
negative
“
−
”
cable
should
be
connected
last
from
the
external
power
source
to
the
negative
“
−
”
terminal
of
the
starting
motor.
If
the
starting
motor
is
not
equipped
with
a
negative
“
−
”
terminal,
connect
the
cable
to
the
engine
block.
Check
the
electrical
wires
daily
for
wires
that
are
loose
or
frayed.
Tighten
all
loose
electrical
connections
before
the
engine
is
started.
Repair
all
frayed
electrical
wires
before
the
engine
is
started.
See
the
Operation
and
Maintenance
Manual
for
specific
starting
instructions.

Typical example
(1) Starting motor to engine block
(2) Ground to starting motor
(3) Ground to battery
Illustration 16

Typical example
(4) Ground to engine
(5) Ground to battery
Correct grounding for the engine electrical system is
necessary for optimum engine performance and
reliability. Incorrect grounding will result in
uncontrolled electrical circuit paths and in unreliable
electrical circuit paths.
