Oil sight glass 

Warning 

Check oil level daily. Never start the compressor with a too low oil level. Risk of accidental 
loss, destruction or deterioration. 

! 

Warning 

•  First oil change after 25 operating hours. 

! 

Compressor Lubrication 

Pistons, cylinders, crankshaft and connecting rods are provided with oil by splash lubrication. 

 

Check oil level 

 

 

 

 

Check oil before each operation of the system! 

The oil level should be between the middle and upper end of 
the oil sight glass. Never start the compressor with a too low 
oil level. 

Refill new compressor oil at least when the oil level reached 
the middle of the indicated area.
