Step-by-Step Cleaning and Maintenance Instructions

1. Clean the Deck of Your Lawn Mower

  2. Use a soft brush to remove grass clippings, dirt, and debris from the underside of the mower deck. Be gentle as not to damage the blades or any other components.
  3. Spray the deck with a garden hose to remove any remaining debris.
  4. Ensure the water does not enter the motor or gas tank (especially for gas-powered mowers).
  5. Dry the underside of the mower using a clean cloth or let it air dry in a well-ventilated area.
  6. Check the Air Filter
  7. If necessary, locate the air filter housing and remove the cover using a screwdriver.
  8. Inspect the air filter for any signs of wear or damage.
  9. If the filter is lightly dirty, clean it gently with a soft brush, a mild detergent, and water. Allow it to air dry completely before reinstalling.
  10. If the filter is damaged or heavily soiled, replace it with a new one. Ensure the replacement filter is the correct size and type for your mower.
  11. Inspect the Spark Plug

2. Gas-powered mowers only:

  1. Locate the spark plug and carefully disconnect the wire (wearing gloves is recommended).
  2. Inspect the spark plug for wear or damage.
  3. If the spark plug is in poor condition, replace it with a new one.
  4. Reattach the spark plug wire once the inspection/replacement is complete.
  5. Change the Oil

3. Gas-powered mowers only:

  1. Locate the oil reservoir and drain plug.
  2. Place a container beneath the drain plug to catch the used oil.
  3. Unscrew the drain plug and allow the oil to drain into the container.
  4. Once drained, replace the plug and fill the reservoir with the appropriate engine oil for your mower.

4. Clean the Fuel System of your Lawnmower

Gas-powered mowers only:

  • Remove the fuel tank cap and drain any remaining gasoline into a container.
  • Use a rag to clean the inside of the fuel tank and remove any dirt or debris.
  • Refill the fuel tank with fresh gasoline and add a small amount of lubricant (e.g., WD-40) to help keep it from gumming up.
  • Replace the fuel tank cap and tighten it securely.

5. Check and clean the Carburetor of your Lawn Mower

Gas-powered mowers only:

  • Locate the carburetor and remove the cover.
  • Inspect the inside of the carburetor for dirt or debris and use a soft brush to clean it, if necessary.
  • Spray the area with a garden hose to remove any remaining debris.
  • Replace the cover and tighten it securely. 

6. Sharpen or Replace Your Lawn Mower Blades

  • Turn off your lawn mower engine and disconnect the spark plug before removing the blades (use a wrench).
  • Inspect both blades for signs of wear or damage and sharpen them if possible using a sharpening stone. If they are severely damaged, you will need to replace them with new ones.
  • Reattach the blades and tighten them securely.

7. Clean Around Your Lawn Mower

  • Once you’ve finished cleaning and maintaining your lawn mower, please clean up the area around it to prevent any dirt or debris from entering the engine or fuel system.
  • Use a garden hose to rinse off any remaining dirt, then use a rag to wipe down the outside of the mower.
