Locate the Filter on Your Lawnmower

Locate the lawnmower's air filter by finding the engine, often on the side or top.

Look for a distinct panel or cover.

The filter could be paper or foam, inside a casing or exposed.

Unscrew or unclip the filter casing. Use the right screwdriver for screws to avoid damage.

Gently handle the filter to check for damage. Note its position for easy reinstallation.

Keep screws or clips in a small container.

Inspect the Filter for Dirt and Damage

Check the lawnmower filter for dirt and damage. A blocked or damaged filter harms engine performance.

• Surface dirt: Look for dust or grass clippings.
• Deeper obstructions: Examine filter folds for debris.
• Light test: Hold filter to light; no light means it's clogged.
• Physical damage: Find any cracks or tears.
• Filter age: Replace if used over a season.

Clean or Replace the Filter

For foam filters, wash with warm soapy water, rinse well, and dry before re-oiling. Gently tap paper filters to remove dirt. Replace if too dirty or damaged.

Filter Type	Cleaning Method	Replacement Frequency
Foam	Wash and oil	Annually or as needed
Paper	Tap gently	Every season
Dual-Element	Clean foam, tap paper	Annually or as needed
Mesh	Rinse with water	Rarely, if damaged
HEPA	Vacuum	Every 100 hours

Regular maintenance keeps your lawnmower's engine efficient.

Reinstall the Filter Properly

Make sure the filter fits perfectly in its slot.

Check its direction, align it without gaps, and press gently.

Clean the housing before installing.

Use the correct filter type.

Inspect for damage.

Secure cover properly.

Test the fit.

• Clean filter housing from dirt.
• Match filter type with lawnmower model.
• Look for damage on filter or housing.
• Align cover when closing.
• Tug filter gently to ensure it's secure.

Test the Lawnmower for Optimal Performance

Test the Lawnmower for Optimal Performance

Start the lawnmower. Listen for strange noises or vibrations. A smooth engine means good performance. Knocking or shaking needs further checks.

Check how the grass is cut. Clean, even cuts show sharp blades and a strong engine. Uneven grass may mean dull blades or engine trouble. The mower should easily cut tall grass. If it stalls, check for a clogged filter or fuel issues.

Watch fuel use. A lawnmower with a clean filter should use fuel evenly. High fuel use might mean a dirty air filter or other problems.
