NOTE: If the person operating the engine does not warm up the engine until the 
thermostat opens, the oil level may lie above the “Max” mark on the dipstick when 
delivered. The correct level can then only be assessed after the engine has been warmed 
up. 
Please follow the steps below to add engine oil: 
1.  Add oil to the engine until the oil level reaches “Max” indicated on the engine 
dipstick. 
2.  In addition, top off the oil quantity in the supply hoses and external oil cooler. 
See section 8.2 for quantities. 
3.  Allow the engine to run warm until the thermostat opens (at approximately 95 
degrees C)
