Low Oil Warning 
Light 
When the oil level falls below the lower level, the oil warning light 1 comes 
on and the engine stops automatically. The engine will not start again until 
oil has been added. 
Note: If the engine stalls or does not start, turn the engine switch to βONβ 
and then pull the recoil starter. If the oil warning light flickers for a few 
seconds, the engine oil is insufficient. Add oil and restart. 
Overload Indicator 
Light (Red) 
The overload indicator light 1 comes on when an overload of a connected 
electrical device is detected, the inverter control unit overheats, or the AC 
output voltage rises. The AC protector will trip, stopping power generation 
in order to protect the generator and any connected electric devices. The 
output indicator light (green) will go off and the overload indicator light 
(red) will stay on but the engine does not stop running. When the overload 
indicator light comes on and power generation stops, proceed as follows: 
1) Turn off any connected electric devices and stop the engine. 
2) Reduce the total wattage of connected electric devices within the 
rated output. 
3) Check for blockages in the cooling air inlet and around the control 
unit. If any blockages are found remove. 
4) After checking, restart the engine. 
Note: The overload indicator light may come on for a few seconds at first 
when using electric devices that require a large starting current, such as a 
compressor or a submersible pump. However, this is not a malfunction. 
Output Indicator 
Light (Green) 
The Output Indicator Light 1 comes on when the engine starts and 
produces  power.
