Changing the Engine Oil and Filter
The engine holds approximately 8.5 qt (8 l) of oil. Change
oil and filter after the first 50 hours, then change both every
100 hours operation. However, change oil more frequently
when engine is operated in dusty or sandy conditions. If
possible, run engine just before changing oil because warm
oil flows better and carries more contaminants than cold
oil.
