2-6 Proper operation of the generator set
2-6. 1 Operating the diesel engine
1. Pre-heat the diesel engine for 3 minutes under no load conditions.
2. Pirst check the height of the Iubricating oil l vel, if it is low, refill it. Our diese! engines are equi-
pped with an alarm system that will notify you if the oil pressure is to low. The alarm system will shut
down the engine if the oil pressure is too low.
3. Do not adjust the speed limit regulation bolt or the fuel adjustment bolt. These bolts have been
set by the factory airead y, changing them will affect the porperties of the engine performance.
2-6.2 Checks during engine operation
1. Check to see if there are abnormal noises.
2. Check to see if the performance is good or bad.
3. Check the color of the exhaust gases (whether it is too black or too white). If any of these condi-
tions exist, stop the engine and find the cause of the problem. lf no problems are found, please
contact your local dealer or our nearest company branch.
2-7 Loading
2-7.1 Load conditions
Exert loads in accordance with the specified parameters.
2-7.2 Output of electricity
1. Raise the revolutions per minute (turn the speed handle to the max setting) of the generator to get
the maximum power out of the generator. lf not, the automatic voltage regulator device will excite
and doing this for long periods of time will cause the capacitor to bum. For the rated speed of the
generator, please refer to Chapter 1, item 1-1 technical specification and data. Observe the pointer
of the voltmeter, it should poin t to 230V ± 5%
2. (50 Hz). (For 60 Hz set, it will be 240V ± 5%). Meanwhile put the switch in the GEN (generator)
position. The AC voltage from the socket of the power supply can be output.
3. When connecting devices to the generator, make sure to connect these devices in order. Connect
the large loads onto the generator first. If everything is functional, smaller loads can then be added.
If the generator shuts off, it may be because the load being drawn by ali the various devices are too
high. In this event, decrease the number of small devices until everything is functional. The total
drawn power should not exceed the maximum output power of the generator. Please see Table 1-
1 for technical specifications of what the generator can output. In order to reset the generator after
overdrawn power, Jet it sit for severa} minutes. If the indication of the voltmeter is too high or too
low, adjust the speed accordingly. If there are problems, stop the generator immediately and fix the
issue.
4. During operation, the generator should be in a place that has very good ventilation. Never cover
the engine to solve a ventilation problem, as this will damage your equipment.
Table 2-1
NOTE:
Do not start more than two devices simultaneously. Each device should be started one by
one to prevent overloading the generator.
The generator should be running at 3600 revolutions per minute in order to achieve the (60Hz)
frequenty. The speed of the engine can be adjusted from the speed governor.
2-7 .3 Charging the battery
l. For the electric starter on the generator, the 12V battery is automatically charged through the
regulator on the side of the engine when it is running.
2. If the generator is not used for long periods of time, the battery should be disconnected
to avoid energy loss from the battery.
3. Do not connect the negative and positive terminals of the battery together at any time. Doing so
will damage the battery.
4. Do not reverse the polarities when attaching the battery cables to the battery. Doing so will
damage both the battery and the electric starter.
5. When charging the battery, the battery produces flammable gases. Do not smoke, let flames, and
sparks get near the battery while it is charging as this may cause a fire. To avoid sparking while
connecting the cables to the battery, first, connect the cables to the battery then to the motor, To
disconnect battery cables, first disconnect the motor end of the cable.
2-8 Stopping the generator
1. Take the electrical load off the generator.
2. Put the speed handle in the "RUN" position and let the engine run for 3 minutes after unloading.
Do not stop the diesel engine immediately let it warm down. Stopping the diesel engine suddenly
may raise the temperature of the engine abnormally and lock the nozzle and damage the diesel
engine. Press down on the brake handle.
NOTE:
1. If the speed handle is in the "Stop" position and the engine is switch running, tum the fuel
sitch to the "OFF" position or loosen the high pressure oil pipe nut. The engine could be stopped
more than one-way other than the speed handle way.
2. lf you cannot stop the engine with a load on it, then remove the load first than stop the engine.
3. If equipped with an electric starter, turn
4. the key to the "Off' position. Put the fuel handle to the "S" position.
5. Finally, pull slowly on the recoil handle
6. Until you feel resistance (this is when the piston is on the compression stroke, where the intake
and exhaust val ves are closed). What this does is prevent the engine from rusting when not in use.
3. MAINTENANCE
3-1 Maintenance schedules
Kepping your generator well maintained will prolong the life of your generator. Everything needs to
be checked including the diesel engine, welder, generator, control cabinet, and frame. For overhau-
ling procedures, please refer to the instruction manual of the relative subassembly. If you need
these manuals, plsaes call our company and we will send you one.
Before starting the maintenance, make sure the diesel engine is off.
Pleaes refer to the Table 3-1 for the proper maintenance schedule.
Table 3-1. Maintenance schedulefor diesel generator set.
Note: "• "mark indicates that it needs special wrench, please contact with dealer.
3- l .1 Changing the engine oil (every 100 hours)
Take the oil cover out.Remove the oil drain plug when the diesel engine is still hot. Be careful of hot
oil and hot engine as you may get bumed. The bolt i located at the bottom of the cylinder. After
draining the oil, put the bolt back and tighten it. Then fill with the proper engine oil to the proper
level.
