BREAK•IN PROCEDURE/DAILY OPERATION
BREAK·INPROCEDURE
After the.generator has been started, check for proper operation
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 /aad~
After the first 10 hours of the generators' operation, the load
can be increased to the full-:load rated output; then periodically
vary the foad. ·· ·
.
Avoid <lverlo~d ~all time:;. ¥ 9yertoa.d i~ .signa}~ by a
smoky eXhaust with l'edoCed: output voltage. and frequency~
Monitor the currentbeing:d.rawn from i:he generator and keep
it within the genei;a.tors~ tating. Since the generator operates
at 1800 rpm to produce 60 hertz; or at 1500 to.produce 50
hertz, control of the generator's engine break~in is governed
by the current drawn from the generator.
To protect against unintentional overloading cjfi:he generator, .
the generator;s output leads should be routed through a circuit
breaker that is· rated· at· the rated output of the generator. ·
NOTE: Be aware of motor starting toads anti th~ high
current drawn required for starting motors. This starting
amperage drawn can be 3 to 5 timesnormalrunning r:zmper-
age. See GENERATOR INFORMATION in.thisfrtanua.L
CHECKLIST
Follow this checklist each day before starting your generator.
• R.ecord the hounneter reading in your log (engine hotirs
relate to the maintenance schedule).•
• Visually inspect the engine for fuel, oil, or water leaks:
II Check the oil level (dipstick).
• Check the coolant levelin the coolant recovery tank.
• Check your fuel supply.
• Check the starting batteries (weekly).
a Check the drive belts for wear and proper tension (weekly).
• Check for abnormal .noise such as knocking, vibration and
blow-by sounds.
• Confirm exhaust smoke:
When the engine is cold -White Smoke.
When the engine is wann - almost Smokeless.
When the engine is overloaded - some Black Smoke.
NOTE: Some unstable running may occur ~n 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 fu:im the generator one at a time.
Allow the generator tb.run for a few minutes to stabilize the
operating temperature and press the STOP switch down, (see
CONTROL PANELS).
NOTE: After the first SO hours of generator operation check
. the nuzintelltlnce schedule for the 50 hour service check.
. GENERAToR ADJUSTMENTS
Once the generator has beeh 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 adjust-
ment may also be required in conjunction with the engine's
speed adjustment (see GENERATIOR INFORMATION).
