LOAD APPLICATION
To hard start load such as an air compressor or
air conditioner, consult the dealer to determine
the max power.
Generator responds to severe overloading
differently than the power line. When
overloading, the engine is not able to supply
enough power to bring the electric motor to
operating speed. The generator responds to the
high initial starting current but the engine speed
drops dramatically. Overloading may stall the
engine. If operated at very low speeds, the
electric motor winding will burn out quickly. The
generator head winding may get damaged.
Running the generator under these conditions
may result in damage to the generator stator as
well as the rotor windings because the heavy
surge of current is required for only an instant.
The generator will not be damaged if it can
bring the motor up to speed in a few seconds.
Turn off all other electrical loads. If possible,
reduce the load on the electric motor.
6.3 Extension cords
When electric power is provided to various
loads at some distance, extension cords can be
used. These cords should be sized to allow for
distance in length and amperage so that the
voltage drop between the set and point of use is
held to a minimum.

CAUTION: Equipment damage can result
from the voltage caused by using an
extension cord with a small wire size.
6.4 AC Application
(1) Observe the indicating voltmeter on the
control panel. The pointer should be in the
green area for load conditions.
(2) When connecting load to the generator,
equipment should be connected in order.
First connect heavy to light load to
generator, then connect restive inductive
load, then re-restive load. If operation order
is improper, the engine speed may drop
sharply and the load should then be
disconnected immediately and checked for
causes.
(3) Balance of three phase generators for
load: When connecting single phase load,
each phase cannot exceed 1/3 of generator
rated power and difference between each
phase amps’ value should not exceed 20%
rated current.
CAUTION: Serious misbalanced load
connected to each phase can cause
burn out of generator set.
If the circuit overload makes the overload
protection switch (main switch) of AC circuit
trip, it is necessary to reduce the circuit
load. Wait several minutes before restoring
the operation. If the indication on the
voltmeter is too high or too low. It is
necessary to stop the generator.
6.5 DC application
Both DC terminals provided output: DC12V,
8.3A, the red terminal is I =i(positive)pole of
power supply. It can be used as load for
rated voltage DC12V and used for charging
12V battery.
(1) To charge the battery with two leads
connected to the start circuit, the negative
lead should be disconnected from the
generator.
(2) Connect the positive and negative
poles of the battery with the positive and
negative poles of DC terminal.
CAUTION: Be careful not to connect
positive and negative leads adversely,
otherwise the generator and the
storage battery will be damaged
severely. Do not let positive and
negative leads touch each other, or the
storage battery will short circuit.
