OIL FILLING
1. Remove the oil fill cap and add the recommended oil to the midpoint of the operating range (midpoint of
the cross hatched region). Adding approximately 5 liters (5.3 quarts) will bring the oil level to mid point of
the cross hatched region.
2. Idle engine for five minutes and check for leaks. Stop the engine. Allow a few minutes for the oil to drain
to the oil sump and recheck the oil on the dipstick. Add oil if necessary.
