Preparing Your Mower for the Oil Change
With your supplies gathered, you’re ready to prepare your mower for the oil change. Follow these steps:
1. Let the Engine Cool Down:
Never attempt to change the oil while the engine is hot. Allow the engine to cool down completely, preferably for at least 30 minutes after running.
2. Park Your Mower on a Level Surface:
Find a level spot to park your mower. This will ensure the oil drains properly.
3. Remove the Spark Plug Wire:
Locate the spark plug wire and disconnect it from the spark plug. This prevents accidental starting and potential injuries.
Draining the Old Oil
Now it’s time to drain the old oil:
1. Locate the Oil Drain Plug:
Refer to your owner’s manual for the exact location of the oil drain plug on your specific Murray model. It’s often located on the bottom of the engine, typically with a plug-like appearance.
2. Place the Drain Pan Underneath:
Position the oil drain pan directly underneath the oil drain plug to catch the drained oil.
3. Loosen the Drain Plug:
Using a wrench, slowly loosen the oil drain plug, turning it counterclockwise.
4. Drain the Oil:
Allow the oil to drain completely into the drain pan. This may take a few minutes.
5. Tighten the Drain Plug:
Once the oil has drained, carefully tighten the drain plug back into place, ensuring it is snug but not overtightened.
Replacing the Oil Filter (If Applicable)
If your Murray push lawn mower has an oil filter, you’ll need to replace it as part of the oil change:
1. Locate the Oil Filter:
Check your owner’s manual to find the location of the oil filter. It’s typically located near the top of the engine.
2. Remove the Old Filter:
Use the oil filter wrench to loosen the old filter. It may be helpful to place a rag around the filter to catch any drips.
3. Install the New Filter:
Before installing the new filter, lightly coat the filter’s gasket with new oil. This helps ensure a good seal. Screw the new filter on by hand until it’s snug. Do not overtighten.
Adding New Oil
With the old oil drained and the filter replaced (if applicable), it’s time to add fresh oil:
1. Locate the Oil Fill Cap:
Consult your owner’s manual for the location of the oil fill cap. It’s usually located on top of the engine.
2. Pour New Oil:
Carefully pour the recommended amount of new oil into the oil fill cap. Check your owner’s manual for the specific amount required. Don’t overfill!
3. Check the Oil Level:
Once you’ve added the oil, check the oil level using the dipstick (if applicable). The oil level should be within the markings on the dipstick. Add more oil if necessary, but avoid overfilling.
Finishing Up
You’ve successfully changed the oil in your Murray push lawn mower. Now, take these final steps:
1. Replace the Spark Plug Wire:
Reconnect the spark plug wire to the spark plug.
2. Wipe Away Any Spills:
Use a rag to clean up any oil spills around the engine.
3. Dispose of Used Oil Properly:
Dispose of the old oil responsibly, following local regulations. Many auto parts stores and recycling centers offer used oil collection.
