REPLACEMENT OF THE ENGINE OIL 
FULL-FLOW FILTER  
Replace the engine oil filter at every 
engine oil change. Before installation of 
a new filter, clean the sealing surface of 
the body (1) and the filter (2). Coat the 
rubber seal with the same oil, with which 
you will fill the engine and tighten the 
new filter by hand. Tighten again the oil 
filter by 3/4 to 1 1/4 turns after the seal 
sits down on the block gasket. After 
starting the engine, check the filter for 
leaks. 
 
 
 
 
 
FILLING THE ENGINE WITH OIL 
Fill the prescribed quantity of oil into the 
filler hole (2), start the engine and let it 
run for 2 to 3 minutes at 750 to 800 rpm. 
After stopping the engine and stabilizing 
the engine oil level, check the oil level by 
means of the dipstick (1). Check the oil 
filter, drain plug (3) and other 
connections for leaks.
