STARTING/STOPPING
PROCEDURE
STARTING
UNDER
COLD
CONDITIONS
Make sure the lubricating oil
conforms
with the ratings for
the prevailing temperature.
Check
the table in the ENGINE
OIL section in this manual.
The battery should be fully
charged
to minimize voltage
drop.
Use a sufficient amount
of
preheat
to aid in starting.
Sec
the
Temperature/Preheat chart on the previous page.
STOPPING
PROCEDURE
1.
Remove the
AC
electrical load from the
generator
and
allow the generator to run for three to five minutes to
sta~
bilize its operating temperatures.
2. Depress the
STOP
switch
and
hold
it
until the
generator
is
completely stopped.
3. Now release the
STOP
switch.
Remote
Stopping
Procedure
To stop the generator, depress the
STOP
switch
which opens the normally closed
\1+
path for
voltage to the engine's run circuit.
The
STOP
switch must be held open until
the
generator
comes
to
a complete stop.
HOTE:
The generator is stopped when the electric

SAFETY
SHUTDOWN
SWITCHES
The
engine
is
protected by three
automatic
shut~
down switches. Should
shutdown
occur, do not
attempt to restart without
finding
and
correcting
the cause.
Refer
to the heading
"Engine
Stops"
in the
TROUBLESHOOTING
section
of/his
manual.
The
following
is
a description
of
these
automatic
shutdown
switches:
High
Exhaust
Temperature
Switch
An exhaust temperature switch is located on the
exhaust
elbow. Normally closed, this
switch
will
open
and interrupt
the
DC
voltage to the fuel
solenoid
on
the injection
pump
(shutting
OFF
the engine)
should
the
switch's
sensor
indicate
an excessive exhaust temperature (an inadequate
supply
of
raw water
causes
high exhaust temperatures).
This
switch
opens at 260-270°F (127-132°C).
This
switch resets
at
approximately 225°F
(lOTC).

SWITCH
A low oil pressure shutdown switch
is
located
off
the
engine's
oil gallery. Normally
open
in
a static state, this
switch's
sensor
monitors the engine's oil pressure. Should the
engine's
oil pressure fall
to
5~
10 psi, this switch will open

SENDER
The
generator's
engine
is
protected by an engine mounted
manual reset circuit breaker
(20
amps
DC). Excessive current
draw
or
electrical overload anywhere
in
the instrument panel
wiring
or
engine
wiring will cause the breaker
to
trip.
In
this
event most generators will shut down because the opened
breaker
disconnects
the fuel supply. If this should occur,
check
and
repair the source
of
the problem. After repairing
the fault, reset the breaker and restart the generator.
