BREAK-IN
PROCEDURE/DAILY
OPERATION
BREAK-IN
PROCEDURE
After
the
generator
has
been started, check
for
proper
opera-
tion
and
then
encourage a fast
warm-up.
Run
the
generator
between
20%
to
60%
of
full
load
for
the
first
10
hours.
A
CAUTION:
Do
not
attempt
to
break-in
your
genera-
tor
by
running
without
a
load.
After
the
first
10
hours
of the generators' operation,
the
load
can
be
increased
to
the
full-load rated output; then periodi-
cally
vary
the
load.
Avoid
overload at
all
times.
An
overload
is
signaled
by
a
smoky
exhaust
with
reduced output voltage
and
frequency.
Monitor
the
current
being
drawn
from
the
generator
and
keep
it
within
the
generators' rating. Since
the
generator operates
at
1800
rpm
to
produce 60 hertz, or
at
1500
rpm
to
produce
50 hertz, control of
the
generator's engine break-in
is
gov-
erned
by
the current drawn
from
the
generator.
To
protect against unintentional overloading of
the
generator,
the generator's output leads should
be
routed
through
a cir-
cuit breaker
that
is
rated at
the
rated output of
the
generator.
NOTE:
Be
aware
of
motor starting loads and the
high
current
drawn
required
for starting
motors.
This
starting
amperage drawn
can
be 3
to
5
times
normal
running
amper-
age.
See
GENERATOR
INFORMATION
in
this
manual.
CHECK
LIST
Follow this checklist each day before starting your
generator.
•
Record
the hourmeter reading
in
your log (engine hours
relate
to
the maintenance schedule).
•
Visually
inspect the engine
for
fuel,
oil,
or water
leaks.
• Check
the
oil level (dipstick).
• Check
the
coolant level in the coolant recovery
tank.
• Check your
fuel
supply.
• Check the starting batteries (weekly).
• Check
the
drive belt
for
wear and proper tension (weekly).
• Check for abnormal noise
such
as
knocking, vibration and
blow-back
sounds.
• Confirm exhaust
smoke:
When
the
engine
is
cold - White
Smoke.
When
the
engine
is
warm
almost Smokeless.
When
the engine
is
overloaded - some Black
Smoke.
NOTE:
Some
unstable
running
may occur
in
a cold
engine.
This
condition should abate
as
normal operating
temperature
is
reached and loads
are
applied.
A
CAUTION:
Do
not
operate
the
generator
for
long
periods
of
time
without
a
load
being
placed
on
the
generator.
STOPPING
THE
GENERATOR
Remove
the
major
AC
loads
from
the
generator
one
at
a
time.
Allow
the generator
to
run
for
a
few
minutes
to
stabilize the
operating temperature
and
press the
STOP
switch
down,
(see
CONTROL
PANELS).
NOTE:
After
the
first 50
hours
of
generator operation check
the
maintenance schedule for the 50 hour service
check.
GENERATOR
ADJUSTMENTS
Once
the generator has been placed
in
operation, there
may
be
governor adjustments required for engine speed
(hertz)
during
the engine's break-in period (first
50
hours) or after
this
period (see ENGINE SPEED (HER1Z) ADJUSTMENT
under ENGINE ADJUSTMENTS. A no-load voltage
adjust-
ment
may
also
be
required
in
conjunction with
the
engine's
speed adjustment
(see
GENERATOR
INFORMATION).
