GENERATOR BREAK-IN PROCEDURE
DESCRIPnON
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 oper-
ated 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 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.
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.
A
CAUTION:
Do not attempt to break·ln 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 witll 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.
GENERATOR ADJUSTMENTS
Once the generator has l:!een placed in operation, there may
be adjdstments required for engine speed (hertz) during
the
engine's break-in period (first 50 hours) or after this period.
A no-load voltage adjusunent may also
be
required in con-
junction with the engine's speed adjustmeqt See
GENERATOR INFORMATION in this mariual.
THE DAILY OPERATION
CHECKUST
·Follow this cheek list each daY' before starting your generator.
0
Check
th,at
alJ...generator circuit breakerS (power panel) are
in the off position before starting.
0
Record the liourmeter reading in your log (engine hours
relate to
th~
maintenance schedule.)
0
VISually inspect the engine for fuel, oil, or water leaks.
0
Check the oil level (dipstick).
0
Check the coolant level in the coolant recovery
tank.
0
eheck your fuel supply.
0
Check the·starting.batteries (weekly).
0
Check drive belts for wear and proper tension (weekly).
CHECK WITH THE ENGINE RUNNING.
0
Check for abnormal noise such as knocking, vibrating and
blow-back sounds.
0
Confirm exhaust_ smoke:
When the engine is cold- Whlte Smoke.
.
When the engine is warm- almost Smokeless.
When the engine is overloaded- some Black Smoke.
START THE GENERATOR
(See STARTING PROCEDURES on previous pages).
Allow the engine to wann up for 5 to 10 minutes to
rea~h
an
operating temperature of 140° to 150°F (60°-66°C) before
applying AC loads. Apply loads systematically allowing the
generator to adjust to each load before applying the next.
Check the gauges for proper oil pressure, operating
temperature, and DC voltage. ·
.
.
NOTE:
Some unstable runn,ing may occur in
!1
cold engine.
This
condition should lessen as nonnal operating
temperature is reached
and
loads are applied.
A
CAUTION:
Oo 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
stabi-
lize the operating temperature and depress the stop switch.
(See STOPPING PROCEDURES on previous pages.)
