Changing Engine Oil
CAUTION Oil is very hot during operation and can
cause burns. Wait for engine to cool before changing oil.
1. Make sure the engine is stopped and is level.
2. Close the Fuel Valve.
3. Place a drain pan (not included) underneath the
crankcase's drain plug.
4. Remove the drain plug and, if possible, tilt the crankcase
slightly to help drain the oil out. Recycle used oil.
5. Replace the drain plug and tighten it.
6. Clean the top of the Dipstick and the area around it.
Remove the Dipstick by turning it counterclockwise, and
wipe it off with a clean, lint free rag.
