STARTING/STOPPING
PROCEDURE
STARTING
UNDER
COLD
CONDITIONS
. Make sure
!he
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
prehea~
to
aid
in
starting. See the
Temperature!Preheat
chart elsewhere
in
this
section.
STOPPING
PROCEDURE
1.
Remove
the
AC
electrical load
from
the generator
and
allow
the
generator to run for three
to
five
minutes
to
stabilize
its
operating temperatures.
2.
Depress
the
STOP
switch
and
hold it until
the
generator
is
completely
stopped.
3.
Now
release the
STOP
switch
.
.
SAFETY
SHUTDOWN
SWITCHES
The engine
is
protected
by
three automatic shutdown
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
this manual.
. The following
is
a description of these automatic
shutdown
switches:
Coolant
Temperature
Switch
A high water temperature switch
is'
located
on
the thermostat
housing. Nonnally closed,
this
switch, should the
fresh
water
coolant's operating temperature
reach approximately
210
0
P
(99°C), will open
and
interrupt
the
DC
voltage to
the
K2'
relay,
thereby shutting off
the
engine.
Tins
switch
resets
at
195°P (107°C).
THERMOSTAT
ASSEMBLY
Remote
Stopping
Procedure
To
stop
the
generator, depress the
STOP
switch
which
opens
the
normally
closed
B+
path for voltage
to
the
engine's
run
circuit.
The STOP switch must be held
open
until
the
generator comes to a complete stop and the
green
LED
light
goes
out.
Low
Oil
Pressure
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,
interrupting the DC voltage to the K2
relay,
thereby
shutting
off
the
engine.

AUDIBLE
ALARM
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
the
generator will shut down
and
the
voltage
to
the
K2
relay
is terminated.
If
this should
occur,
check
and
repair the
source
of
the
problem. After repairing
the
fault,
reset the
breaker and restart
the
generator.
