OIL LEVEL INDICATOR
OIL LEVEL INDICATOR
When the oil level falls below the level required for operation, the oil level indicator lights up, and then the engine
stops automatically. The engine will not start until oil is added.
AC INDICATOR
AC INDICATOR
When the generator is running and producing electricity, the AC indicator light is on.

Once the generator is working in the normal mode, output voltage light is
green. In case of overload, indicator lights red. After 2 minutes working in overload mode, protection device switches
on and turns off the power generation to protect the connected electrical equipment and generator. In the event
of a short circuit, protection device immediately shuts off electricity. In both cases, indicator is blinking red, but the
engine does not stop.
Restart the engine to make the generator produce electricity again.
The overload indicator may light up within several seconds after
start-up or when connecting electrical devices requiring a high
starting current, such as a compressor. However, this is not a
malfunction.

The DC protector automatically switches to “OFF” when the current of the operating electrical device is higher than the
rated current. To use this equipment again, turn on the DC fuse again by pressing the “ON” button.
RESET BUTTON FOR MODEL KSB 21
RESET BUTTON FOR MODEL KSB 21
ii S:
S: The RESET button has a built-in overload indicator. When approaching the
overload condition, the indicator starts flashing. The overload indicator lights up when the connected generator is
overloaded, the inverter control unit overheats or the AC output voltage rises.
If the overload indicator goes on, the engine will continue to operate, but the generator will no longer produce
electricity. In this case, you must perform the following steps:
1. Turn off all connected electrical appliances.
2. Reduce the total power of the connected devices until the nominal power of the generator is reached.
3. Press the RESET button once to restore socket voltage. After that the WORKING MODE indicator will flash 3 times
and the power supply will be restored.
If the DC fuse turns off, reduce the load of the connected electrical
device. If the DC protector turns off again, stop operation and
contact your nearest K&S Basic
®
service center.

The fuel cap is equipped with a vent for air supply to the fuel tank. When the engine is running, the vent must be in
the “ON” position (OPEN). This will allow fuel to enter the carburetor for engine operation. When the generator is not
in use, close the vent to the “OFF” position.
GROUND TERMINAL
GROUND TERMINAL
The ground terminal forms a ground line to prevent electric shock. If the electrical appliance is grounded, the
generator must also be grounded.
Make sure that the control panel, the blinds and the underside
of the inverter are well cooled and protected against the ingress
of small solids, dirt, and water. Improper operation of the cooler
can cause damage to the motor, inverter or alternator.
