OPERATE YOUR GENERATOR
5 Operation for Generator Set
5.1 Handle the Diesel Engine
5.1.1 Avoid overload
While your diesel engine is new, applications
of heavy loading may shorten the engine’s life.
It must run a light load within the first 20 hrs.
(1) Avoid overload: Avoid applying any heavy
load during the initial 20 hrs.
(2) Change the lube oil regularly: Change the
lube oil after 20 hours of initial operation or at
the end of the first month and then once every
50 hours for 3 times, every 3 months, or every
1000 hours thereafter.
NOTE: The lube oil should be drained while
the diesel engine is hot. If cooled, it is very
difficult to drain the engine oil completely.
5.1.2 Warm up the diesel engine for 5 minutes
without any load.
5.1.3 Check the indicator lamp
Though equipped with low oil pressure
protection system, it is necessary to check
whether the indicator lamp of oil pressure
signal lights up. The lube oil alarm indicator
will light when the oil pressure is low or the
lube oil is insufficient and the diesel engine will
shut off automatically. The engine will not be
started until refilling oil to safe level.
5.2 Inspection during the engine running.
(1) Abnormal sound or vibration;
(2) Color of exhausted gas, black or white;
(3) Excessive change in engine speed;
(4) Sparking or arcs from generator;
(5) Loss of electrical output;
(6) Engine has Fire.
(7) Flame or Smoke.
If you find one of the above-mentioned issues,
it is necessary to turn off machine. Please
contact the dealer.
5.3 Generator Operation Speed
The generator must be run at the correct
speed to produce the proper electrical voltage
and frequency. The speed of the engine was
carefully adjusted at the factory so the
generator produces the proper voltage and
frequency.
WARNING: Do not adjust the speed or fuel
limit bolt of the diesel engine. (They were
properly adjusted when delivered from
factory) If changed, the engine’s
performance will be affected.
Before connecting a load to the generator, the
pointer of the voltmeter should be in the green
area to ensure the generator is working
properly. Failure to do so could result in
damage to the equipment plugged into the unit
and possible injury.
All engines tend to slow down when a load is
applied. When the electrical load is connected
to the generator, the engine is more heavily
loaded and thus the speed drops slightly. This
slight decrease in speed together with the
voltage drop results in a slightly lower voltage
when the generator is loaded to its full
capacity than when it is running with no load.
