when filling with fuel.  

-

 

Wear gloves when searching for a possible leak. 

-

 

Hot  oil  can  cause  burns,  allow  the  engine  to  cool 
before  inspecting  the  oil  level,  changing  the  oil  or 
the oil filter cartridge. 

-

 

Always  use  fuels  and  lubricants  recommended  by 
NANNI DIESEL 

 
EXHAUST GAS PREVENTION
