1. Gather the necessary materials: new oil (SAE 30 or SAE 10W-30), oil filter (if applicable), oil drain pan, funnel, and a wrench.
2. Prepare the lawnmower: Park the lawnmower on a level surface, engage the parking brake, and turn off the engine. Allow the engine to cool down completely.
3. Locate the oil drain plug: The oil drain plug is usually located on the side or bottom of the engine. It may be marked with an oil can symbol.
4. Place the oil drain pan: Position the oil drain pan underneath the oil drain plug to catch the old oil.
5. Remove the oil drain plug: Use the wrench to loosen and remove the oil drain plug. Be careful not to drop the bolt into the oil drain pan.
6. Allow the old oil to drain: Let all of the old oil drain out into the pan. This may take a few minutes.
7. Replace the oil drain plug: Once all of the old oil has drained out, replace the oil drain plug and tighten it securely.
8. Locate the oil fill cap: The oil fill cap is usually located on the top of the engine. It may be marked with an oil can symbol.
9. Add new oil: Use the funnel to add new oil to the lawnmower. Refer to the owner's manual for the correct amount of oil.
10. Replace the oil fill cap: Once you have added the correct amount of oil, replace the oil fill cap and tighten it securely.
11. Check the oil level: Use the dipstick to check the oil level. The oil level should be between the "Full" and "Add" marks on the dipstick.
12. Dispose of the old oil: Dispose of the old oil properly by taking it to a recycling center or automotive repair shop.
That's it! You have successfully changed the oil in your Craftsman 625 series lawnmower.
