BREAK-IN PROCEDURE/DAILY OPERATION
BREAK-IN PROCEDURE
After the generator has been started, check for proper
operation and then encourage a fast wann-up. Run the gener-
ator between 20% to 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 generators' operation, the load
can be increased to the full-load rated output; then
periodically
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 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 engine break-in is
governed 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
circuit 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
amperage. See GENERATOR INFORMATION in this
manual.
CHECK LIST
Follow this checklist each day before starting your generator.
• Record the hourrneter 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 belts for wear and proper tension
(weekly).
• Check for abnonnal noise such as knocking, vibration and
blow-by sounds.
• Confinn 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 in a cold engine.
This condition should abate as normal operating temperature ·
is reached ait.d loads are applied.
A
CAUTION: Do not operate the generator tor long
periods of time without a load being placed on the
generator.
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.
NOTE:
After the first 50 hours of generator operation check
the maintenance schedule for the 50 hour service check.
