(2) Concerning the generating set with Low Oil Warning
System, check that the Oil Alarm Lamp is not lit.
NOTICE
•For the generating set with Low Oil Warning System, the Oil Alarm Lamp will e activated y low oil pressure or
engine oil shortage, simultaneously, the engine will stop. The engine will stop immediately if restarted without
refilling the engine oil. Check the oil level and refill.
•Do not loosen or readjust either the engine speed limiting olt or fuel injection limiting olt, otherwise, the
performance will e affected.
6.2 Checks during the running
•Whether there is a normal sound or vi ration;
•Whether the engine miss fires or runs rough;
•Check the color of the exhaust. (ls it lack or too white?)
lf you notice any of the a ove-mentioned phenomenon happened, stop the engine and find out the
fault cause or contact the authorized service center.
CAUTION
•If the engine has een running, the muffler will e very hot. Be careful not to touch the muffler.
•Never refill the fuel tank while the engine is running.
6.3 reak-in period operation
The first 20hrs are the reak-in period of the engine, the operator must o ey to following items:
•Warm up the engine 5 minutes after the initial starting. Run the engine at low speed and
zero load efore the engine ecomes warm.
•Avoid applying any heavy loads during the reak-in period. we recommends to run the
engine at 3000r/min with 50% load in reak-in period.
6.4 Replace the engine oil on time.
•Replace the engine oil while the engine is warm after 20-hours-running, the old engine oil
will e drained out completely.

7. LOAD
NOTICE
•Do not start 2 or more loads simultaneously. Start them one y one.
•Do not use floodlights together with other loads.
•Start motor type load first and then resistive load.
7.1 AC application
1. Be sure to run the generating set at rated speed, otherwise AVR (Automatic Voltage
Regulator) will produce the forced excitation. If the genset runs long time under such
condition, AVR will e urned out.
2. After switching on the air reaker, o serve the voltmeter on the control panel, the voltmeter
should point to 230V±5% (50Hz) for single-phase generator set, 400V±5% (50Hz) for three-
phase generator ser, then connect the loading to the unit. (The actual voltage of genset is
vary with local code.)
3. When the dou le voltage generator set changes over the voltage, the circuit reaker should
e set at "OFF" position. Otherwise the generator set and load will e urned out and
damaged.
4. Connect different loads to the generator set in order. In case of motor load, firstly the heavy-
duty motor should e connected, then the light-duty motors. If the operation is false, the
generator set will lag or stop suddenly. lt is necessary to unload the generator set
immediately and turn off the main switch and do checks.
5. Three-phase generating set
•Balance three phases during the operation. Stop the engine for check if the tolerance
exceeds 20%. Be sure to keep the tolerance among three phases less than 20%.
•The load for each phase must elow the rated load as well as the current must less than
rated current.
A, B,C,D (or U, V, W, N) phase arrangement should e from left to right, or clockwise.
•Concerning starting the three phase asynchronous motors, first start the heavy duty motors,
then start the light-duty motors.
NOTICE
•If overloading of the circuit trips the AC circuit protector, reduce the load on the circuit, and wait a few minutes
efore resuming operation.
•Breaker can prevent the electric shock. The replacement must features same degree and performance.
•Electrical equipment (including electrical lines and plugs connection) must e free of defect. By the effect of
mechanical stress, make sure to use the ru er sheathed flexi le ca le or analog (meet with IEC245-4).
•Limit length of electric wires y extending wire or distri uted wiring network: 1.5mm
2
ca le must e less than
60m, and 2.5mm
2
ca le should e less than 100m.
7.2 DC application
1. DC terminals are only for charging 12V attery.
2. Set the circuit reaker at "OFF" position while charging. Connect charging wires to 12V
output terminals.
3. Concerning the automatic type attery with the leads, e sure to disconnect the negative
leads of the attery while charging.
CAUTION
•Connect the positive and negative poles of the attery with the positive and negative poles of DC terminals
separately. Do not confuse them, otherwise the attery and generating set will urn out.
•Do not connect the positive pole of the attery with its negative pole, otherwise the generating set damage will
result.
•When a large capacity attery is charged, excessive current flows, the fuse for the direct current will urn out.
•Do not run the generating set while it is still connected with the external attery.
•Do not use DC12V and AC simultaneously.

CAUTION
•To prevent from creating a spark near y the attery, always connect the charging ca les to the attery first and
only then to the generating set. Disconnecting should e conducted from genset first.
•Charge the attery at a well-ventilated place.
•Remove the cap from each cell of the attery efore charging.
•Stop charging if the electrolyte temperature exceeds 45 .℃
7.3 Typical appliance reference
Electrical appliance particularly motor-driven equipment will produce very high current while
starting, the elow ta le provides the reference for connecting these apparatus to the generator
set.
