December 2010 / M-SC6/8/10 / EN 

PROBLEM CAUSE 

SOLUTION

•

 Wear out of cylinder. 

Have the compression measured and have the 
engine overhauled. 

 

 

 

Over-temperature 

•

 Overload.  

Take away the overload. 

•

 Low level of cooling oil or air in the 

cooling system  

Fill up with liquid and release air bubbles. 
Check if there are air blocks in the system; 
refer to the installation manual  

•

 Water inlet system blocked. 

•

 Broken impeller. 

•

 Water strainer choked 

•

 Heat exchanger choked. 

Check the cooling system thoroughly. 

•

 Broken or slipping V-belt. 

Replace and adjust the V-belt tension. 

•

 Faulty thermostat 

Check the thermostat or replace. 

 

5.2.3 Warnings 

 

 

 
Generator must be shut off immediately if:   

 

●

 Motor RPM suddenly rises or drops.  

●

 Unusual noise comes from generating set.  

●

 Exhaust gases suddenly colour dark.  

●

 Engine failure warning light is on  

 

5.2.4 Service
