Adding Engine Oil on page 9.
Changing Engine Oil
For a new engine, change oil after the first 5 hours of
operation. Thereafter, change oil after every 50 hours of
operation.
Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities. Make sure
the engine is level when filling, checking, or changing oil.
Change the oil as follows:
• To keep dirt, grass clippings, etc., out of the engine,
clean the area around the drain plug and dipstick
before removing it.
• Remove the oil drain plug and dipstick. Tilt the engine
slightly towards the oil drain to obtain better drainage.
Be sure to allow ample time for complete drainage.
Reinstall the drain plug. Make sure it is tightened
securely.
Fill the crankcase with new oil of the proper type, to
the Full mark on the dipstick. Always check the level
with the dipstick before adding more oil.
