BREAK-IN
PROCEDURE
DESCRIPTION
Although your engine has experienced a minimum
of
one
hour
of
tcst operations at the factory to make sure accurate
assembly procedures were followed and that the engine oper-
ated
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
pis-
ton fings to the cylinder walls. Excessive oil consumption
and
smoky
operation indicate that the cylinder walls arc
scored, which is caused
by overloading the generator 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.
AFTER
START-UP
Once the generator has been started, check for proper opera-
tion and then encourage a fast warm-up. Run the generator
hetween
20%
and 60%
of
full-load for the first 10 hours.
A
CAUTION:
Do
not
attempt
to
break-in
your
generator
by
running
without
a
load.
After the first 10 hours of the generator's 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
smoky exhaust with reduced output voltage and frequency.
Monitor the current being drawn from the generator and keep
it
within the generator's 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 break-in
is
governed
by
the current drawn from the generator.
CHECK
THE
FOLLOWING
D Monitor the control panel gauges.
o Check for leaks
of
fuel and engine oil.
D Check for abnormal noise such as knocking, friction,
vibration and blow-back sounds.
D 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.
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
currelll
draw required for
Slarling motors. This starting
amperage
draw can
be
3 to 5 limes
normal
running amperage.

GENERATOR
ADJUSTMENTS
Once the generator has been placed
in
operation, there may
be adjustments required for engine speed (hertz) during the
engine's break-in period (first
50 hours)
or
after this period.
A
no-load voltage adjustment may also be required
in
con-
junction with the engine's speed adjustment.
