The national Electrical Code requires that the frame and
external electrically conductive part of this generator be
properly connected to an approved earth ground. Proper
grounding of the generator will help prevent electrical
shock in the event of ground fault condition in the
generator or in connected electrical devices. Proper
grounding also helps dissipate static electricity, which
often builds up in ungrounded devices.

5. 1. 1 AVOID OVERLOAD
OVERLOAD WILL DECREASE THE LIFETIME OF THE GENERATOR.USE IT IN
LIGHT LOAD IN THE FIRST 20 HOURS TO ENSURE THE RUN-IN PERIOD.
REPLACE OIL AFTER FIRST 20 HOURS RUNNING OR AT THE END OF THE
FIRST MONTH'S USING,THEN REPLACE EACH 50 HOURS.REPLACE OIL EACH
100 HOURS OR EACH 3 MONTHS AFTER THREE TIMES REPLACEMENT OF OIL.
5. 1. 2 PREHEAT THE GENERATOR 5 MINUTES WHEN DISCONTINUOUS
LOADING.
5.1.3 LOW OIL ALERT LAMP
Because low oil alert lamp fitted, it will light at low oil level or little oil, it keeps lighting if restart
the generator without add the oil. Check the oil level before starting, add the oil if needed.
5.2 CHECK THE GENERATOR DURING OPERATION
a) Excessive speed fluctuation, slow or fast
b) Overheating of the load wires
c) Sparks or electrical arcing within the generator
d) No voltage output
e) Socket damage or GENERATOR fire
f) Abnormal vibration
g) Flame or smoke
If any one of above occurs, please stop it immediately and contact the dealer.
5.3 OPERATING SPEED OF GENERATOR
Generators outputs normal voltage and under rated speed.
Running speed is adjusted well in factory. When connecting load, checking output voltage to
make sure the generator works well.
ADD LOADING
6 ADD LOADING
6.1 DETERMINE THE TOTAL LOADING OF GENERATORS
Determine the total loading which are connected to the generat
or is very important. The total
loading cannot exceed the rated power of the generator. The 2 main factors which affect the
generator’s lifetime is: winding temperature and winding corrosion. If the generator operates
overloaded, winding temperature becomes overheated, short-circuiting may occur after
long term operation.
Before starting the generator, make ensure the consistency between generator’s
nameplate data and electrical equipment’s power, voltage, current and frequency.
Because power is affected by equipment efficiency, power factor and other factors, some
equipments’ starting power is 3-10 times larger than runni
ng power.
REMINDER: IF ELECTRICAL EQUIPMENT’S POWER NOT SHOWN IN NAMEPLATE, IT
CAN BE
CALCULATED APPROXIMATELY BY VOLTAGE PLUS CURRENT(VOLTAGE x CURRENT).
Voltage × current = power Example: 220V × 5A = 1100W
10
NOTE: DO NOT LOSSEN OIL LEVEL LIMIT BOLT AND SPEED LIMIT BOLT, BOTH OF THEM
ARE ADJUSTED WELL IN FACTORY, OTHERWISE GENERATOR’S PERFORMANCE WILL BE
AFFECTED.
When adding load, all diesel generator’s rotational speed tends to decrease. When appliances are
connected to the generator and loading increased, it will result in engine speed decreasing and
output voltage lower compared with no-loading. If the generator does not reach the rated speed,
there will be no obvious affect for most of the loadings such as motors and lights but the electrical
appliances may be affected. The output voltage must be checked periodically to ensure proper
operation of generators and loadings. A portable voltmeter could be used to measure the voltage
while a tachometer to be used to measure the speed to get the working frequency.
5.4 MAINTENANCE OF GENERATOR
Generators must run every four weeks, keep no loading for 10-15 minutes,which could remove the
moisture and dust adsorbed on the windings. If not, the windings may be rusted and generator will
not operate properly.
When the load is a resistive load such as incandescent, heater or common power tools, using
electrical appliances can refer to rated power. If the load is inductive and resistive mixed loads
such as fluorescent lamps, mercury lamp, transformers, fans, small blowers or inductors,using
electrical appliances can only refer to 60% rated power.
NOTICE: WHEN GENERATOR REACH OPERATING SPEED THEN CAN ADD LOAD .

(a) Cold to start the motor need 5-7 times rated current.
(b) Because the temperature of the compressor head requirements 15 minutes after restarting
6.2 START ELECTROMOTOR
When start electromotor need large current, some electromotor es
pecially phase motor with low
power is hard to start and needs 5-7 times running current. Capacitor start motor needs 2-4 times
running current. Permanent magnet motor need 1.5-2.5 times running current.
When overloaded, the generator will not run basis on the power characteristic curve, the rotate
speed of diesel engine doesn’t increase, which couldn’t output enough power to drive
electromotor to reach the working speed. The generator could make a response on a large initial
starting current. However, a sharp decline in engine speed, may cause generator stop. If allowed
to run with a very low speed, the motor windings will be abla
ted in a very short time, in this low
speed operation it could lead to the stator and motor windings burn out soon. Because of starting
a large current just a moment, When the generator speed quickly rises to the operating speed,
11
the generator will not damage. If starng the electromotor is difficult in a short me, turn off
other electrical loads and minimize the load of the electromotor.
6.3 CONNECTING WIRE
When supplying power some far from generator, connecng wire will be applied. The dimensions
of the wire used must conform to the requirements of the cross secon and length, in order to
keep the voltage drop within a very small value between electricity terminal and supply terminal.
NOTICE: USE A SMALL SIZE DIMENSION WIRE MAY CAUSE DIVICE DAMAGE.
6.4 AC APPLICATION
(1)Check the three in one meter display to make sure the current and voltage in allowed range,
then loading can be
added.
(2) Each loading must be connected on generator in order:
first connecng larger loading, then smaller loading; first connecng inducve loading, then
resisve loading. If order is reversed and cause generator’s speed decline sharply, loading must
be disconnect immediately.
(3) The balance of the three-phase generator load:
When a single phase loading connected on a three phase generator, each phase power can not
exceed 1/3 of the generang total power, each phase’s current D-value must be less than 20% of
the rated current.
If the circuit overload let switch trip for AC circuits, please reduce circuit loading.
If the voltage in
three in one meter shows too high or too low, shut down the generator to check the reason and
sweep the trouble, then restart.
6.5 DC APPLICATION
DC binding post provides power source: DC12V 8.3A，red binding post is “+” pole of power source;
black binding post is “-“ pole of power source. The power source can be used in 12V DC load, as
well as can be used in charge baery.
(1)When charge generator baery by DC output which connected to the generator by wire, must
disconnect the wire “-“ pole which connected to the generator.
(2)Connect the baery “+” pole, “-“ pole separately with generator DC “+”
pole and “-“ pole by
charging wire.
REMARK: DC LOAD CURRENT CAN NOT EXCEED 8 A, WHEN CHARGE IN LARGE CAPACITY BATTERY,
THE FUSE OF DC SOURCE CAN BURN OUT EASILY DUE TO BIG CURRENT.
WARNING: DO NOT REVERSE THE CHARGING WIRE’S POSITIVE POLE AND NEGATIVE POLE. ONCE
REVERSED, CAN CAUSE A BAD DAMAGE IN GENERATOR AND STORAGE BATTERY. DO NOT LET THE
POSITIVE POLE CONNECT WITH NEGTIVE POLE, OTHERWISE CAN CAUSE SHORT CIRCUIT IN
BATTERY.
DANGER: THE BATTERY CHARGING CAN PRODUCE FLAMMABLE HYDROGEN GAS, KEEP AWAY
FROM SPARKS, FLAMES AND SMOKE WHEN
CHARGING. IN ORDER TO AVOID SPARKS NEARBY,
CONNECT THE STORAGE BATTERY FIRST, AND THEN CONNECTED TO THE GENERATOR,.WHEN
DISCONNECTED, FIRST DISCONNECTED THE GENERATOR SIDE. CHARGE BATTERY IN A WELL
VENTILATED PLACE.
6.6 SINGLE THREE PHASE OPERATION
Determine the load type before using single phase or three phase. Use the single/three phase
switch on the panel for selecon and judge the voltage and current by three in one meter.
