GENERATOR
BREAK-IN
PROCEDURE
DESCRIPTION
Although your engine
has
experienced a minimum of one
hour of test operations at
the
factory to
make
sure accurate
assembly procedures
were
followed and that
the
engine
operated
properly,
a break-in
time
is
required. The service
life of your engine
is
dependent upon
how
the engine
is
operated
and
serviced during
its
initial hours of
use.
Breaking-in a
new
engine basically
involves
seating the
piston
rings
to
the cylinder
walls.
Excessive oil consumption
and
smoky
operation indicate that the cylinder
walls
are
scored,
which
is
caused
by
overloading the engine during the
break-in period.
Your
new
engine requires approximately 50
hours
of initial
conditioning operation
to
break in each
moving
part in order
to
maximize
the
performance and service life of the engine.
Perform
this
conditioning
carefully,
keeping in
mind
the
following:
Start
the
engine according
to
the
STARTING
PROCEDURE
section.
Run
the
engine
while
checking that all systems
(raw
water
pump,
oil pressure, battery charging)
are
functioning.
reach
its
full
rated speed
are
signs
of
an
overload.
AFTER
START-UP
Once the generator
has
been started, check for proper opera-
tion
and
then
encourage a fast
warm-up.
Run
the
generator
between
20%
and
60%
of
full
load for the
first
10
hours.
After the
first
10
hours
of
the generators operation, the
load can be increased
to
the full-load rated output, then
periodically
vary
the load.
Avoid
overload at all times. An ovefload
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
to
produce 50 hertz,
control of the generators engine break-in
is
governed
by
the
current drawn from the generator.
NOTE:
Be
aware
of
motor starting loads and
the
high
current
drawn
required for starting motors.
This
starting
amperage
draw
can
be 3
to
5 times normal running
amperage.
See
GENERATOR INFORMATION
in
this
manual.
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 (HERTZ) ADJUSTMENT under
ENGINE
ADJUSTMENTS. A no-load voltage adjustment
may
also
be required in conjunction with the engine's speed adjust-
ment
(see
GENERATOR
INFORMATION).
THE
DAILY
ROUTINE
CHECK
LIST
Follow
this
checklist each
day
before starting your generator.
• Check that
all
generator circuit breakers
(power
panel)
are
in
the
off position before starting.
• 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
WITH
THE
ENGINE
RUNNING.
• 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
AC
loads
from
the generator
one
at
a
time.
Allow
the generator
to
run for
3-5
minutes to stabilize the operating
temperature, then
turn the
key
to
the
off position. Once the
generator
is
shutdown, close
down
all
circuit breakers
as
a
safety precaution.
