Preparing for the Oil Change: Tools and Materials

Before diving into the oil change itself, it’s crucial to gather the necessary tools and materials. This ensures a smooth and efficient process, minimizing the need to stop and search during the task.

Essential Tools and Materials

  • New Engine Oil: Refer to your Craftsman M220 lawn mower manual for the recommended oil type and viscosity. Typically, 10W-30 or 10W-40 oil is suitable for most lawn mowers.
  • Oil Filter: If your Craftsman M220 has an oil filter, ensure you have a replacement filter that fits your model.
  • Oil Drain Pan: A pan to catch the used oil.
  • Wrench or Socket: This is needed to loosen the drain plug.
  • Filter Wrench (if applicable): A tool specifically designed to remove oil filters.
  • Gloves: Protect your hands from the used oil.
  • Shop Rags: For cleaning up spills and wiping off tools.
  • Safety Glasses: To protect your eyes.

Safety Precautions

  • Wear gloves and safety glasses throughout the process. Used oil can irritate your skin and eyes.
  • Perform the oil change in a well-ventilated area. Oil fumes can be harmful if inhaled.
  • Never dispose of used oil down the drain.
  • Ensure the engine is completely cooled down before starting the oil change. Hot oil can cause burns.

Step-by-Step Guide to Changing the Oil

Now that you’ve gathered the necessary tools and taken the necessary precautions, it’s time to change the oil in your Craftsman M220 lawn mower.

Step 1: Locate the Oil Drain Plug and Fill Cap

  1. Find the oil drain plug. On most Craftsman M220 models, it’s usually located on the bottom of the engine block, often with a bolt or a hexagonal nut.
  2. Locate the oil fill cap. This is typically on the top or side of the engine, often marked with a symbol of an oil can.

Step 2: Warm Up the Engine (Optional)

While not mandatory, warming up the engine for a few minutes can help thin the oil, making it drain more efficiently.

Step 3: Drain the Oil

  1. Place the oil drain pan directly under the drain plug.
  2. Carefully loosen the drain plug using your wrench or socket.
  3. Allow the oil to drain completely into the pan. This may take a few minutes.

Step 4: Change the Oil Filter (if applicable)

  1. Locate the oil filter. It’s typically attached to the engine block, often near the oil fill cap.
  2. Use a filter wrench to loosen the filter. Be careful not to damage the surrounding parts.
  3. Remove the old filter.
  4. Wipe clean the area around the filter housing.
  5. Install the new filter. Ensure it is properly tightened, but avoid over-tightening.
  6. Add a small amount of clean oil to the new filter’s sealing gasket. This helps ensure a proper seal.

Step 5: Add New Oil

  1. Remove the oil fill cap.
  2. Slowly pour the recommended amount of new oil into the engine. Check your owner’s manual for the specific oil capacity for your Craftsman M220 model.
  3. Ensure you don’t overfill the engine. Leave a small gap between the oil level and the top of the fill cap.
  4. Replace the oil fill cap securely.

Step 6: Start the Engine and Check for Leaks

  1. Start the engine and let it run for a few minutes.
  2. Stop the engine and carefully check for any leaks.
  3. Wipe away any drips with a shop rag.

Step 7: Dispose of the Used Oil Properly

  • Never pour used oil down the drain or into the garbage.
  • Contact your local recycling center or a hazardous waste facility for proper disposal instructions. They may offer collection services or have designated drop-off locations.

What type of oil should I use in my Craftsman M220 lawnmower?

The Craftsman M220 lawnmower requires 10W-30 oil, which is a common type of oil for small engines. You can use both synthetic and conventional oil, but it’s important to choose an oil that meets the API (American Petroleum Institute) service classification for your mower. Check the owner’s manual for specific recommendations.

It’s recommended to use a high-quality oil, as it will help to protect your mower’s engine from wear and tear. Always use oil that is specifically designed for lawnmower engines, as other types of oil may not be compatible with your mower.

How much oil should I put in my Craftsman M220 lawnmower?

The Craftsman M220 lawnmower requires approximately 18 ounces of oil. It’s important to use the correct amount of oil, as too much or too little oil can damage your mower’s engine. Check the oil dipstick to see how much oil is already in your mower and add the appropriate amount of oil.

When filling your mower, be sure to avoid overfilling the engine. Overfilling can cause oil to leak out and damage your engine. Always check the dipstick after adding oil to ensure you have the correct level.

Where do I put the oil in my Craftsman M220 lawnmower?

The oil filler cap is typically located on the top of the engine, near the air filter. It will have a symbol that looks like a drop of oil. You can remove the cap and pour the oil in, then replace the cap tightly.

It’s important to use a funnel when adding oil to your lawnmower to prevent spilling and getting oil on your hands or other parts of your mower. This will help to keep your mower clean and avoid any potential hazards.

How often should I change the oil in my Craftsman M220 lawnmower?

It’s recommended to change the oil in your Craftsman M220 lawnmower every 25 hours of use or at least once per season. However, the frequency may vary depending on the type of oil you use, the environment you mow in, and the usage pattern. Check your owner’s manual for specific recommendations.

Changing the oil regularly helps to keep your mower’s engine clean and running smoothly. Fresh oil helps lubricate the engine’s moving parts, preventing wear and tear and extending the life of your mower.

How do I drain the old oil from my Craftsman M220 lawnmower?

To drain the old oil, first, you need to locate the oil drain plug. It’s usually found on the bottom of the engine, near the crankshaft. Place an oil drain pan underneath the plug and use a wrench to loosen and remove the plug. Let the oil drain completely.

Once the oil has drained, replace the drain plug and tighten it securely. Make sure to dispose of the old oil properly, as it’s harmful to the environment.

What do I do if I overfill the oil in my Craftsman M220 lawnmower?

If you accidentally overfill the oil in your Craftsman M220 lawnmower, you need to remove the excess oil. You can do this by using a syringe or turkey baster to suck out the excess oil.

Be careful not to suck out all the oil. Once you’ve removed the excess oil, check the oil level again using the dipstick. Make sure the oil level is between the “full” and “low” marks on the dipstick.

What other maintenance tasks should I perform on my Craftsman M220 lawnmower?

Besides changing the oil, there are several other maintenance tasks you should perform on your Craftsman M220 lawnmower to keep it running smoothly. These include:

  • Changing the air filter: A dirty air filter restricts airflow to the engine, reducing its efficiency.
  • Sharpening the blades: Dull blades can cause uneven cuts and damage your lawn.
  • Cleaning the mower deck: Removing grass clippings and debris from the mower deck prevents rust and corrosion.
  • Checking and adjusting the spark plug: A worn-out or improperly gapped spark plug can cause starting problems.
  • Checking the tire pressure: Properly inflated tires improve traction and handling.

Regular maintenance will help to ensure your Craftsman M220 lawnmower lasts for many years to come.
