d)  Changing engine oil

 

Change the oil once after the first 50 - 150 hours of use and then every 500 hours of engine 
operation thereafter.  The generator set is equipped with an hour meter to record actual engine 
operating time.   

The ideal time to change engine oil is soon after a power delivery run, when the engine is at 
operating temperature. If lubricating oil is drained immediately after the unit has been run for 
some time, most of the sediment will be in suspension and will drain readily. 

Change the oil filter element each time the oil is changed. 

 

CAUTION 

 

 

High ash oils may produce harmful deposits on valves that can cause valve 
burning. 

 

Do not use solvents as flushing oils in running engines. 

 

Always use clean containers, funnels, etc.
