Mountfield SP42 Self-Propelled Petrol Lawn Mower

Refer to the user manual for the specific oil type and procedure. Typically, you'll need to warm the engine, drain the old oil, and refill with the correct amount of fresh oil.

Use fresh, unleaded petrol. Always check the manual for the recommended octane rating.

Sharpen the blade at least once per season, or more frequently if you mow frequently or encounter obstacles.

Drain the fuel, clean the mower, remove the spark plug, and store it in a dry place. Consider adding fuel stabilizer before storage.

Mowing wet grass can clog the mower and affect performance. It's best to mow when the grass is dry.

Warranty information is available from the seller. Consult the warranty documentation that came with the product.

Remove the air filter cover, take out the filter, and clean it. You can tap it against a hard surface to remove debris, or replace it if it's heavily soiled.

Check the fuel tank for fuel, ensure the spark plug is connected, and check the oil level. Ensure the Autochoke is engaged properly.

Check the blade for damage and sharpen or replace it. Ensure the cutting height is correctly adjusted. Check for bent blades.

Check the drive belt for wear or breakage. Inspect the drive mechanism for obstructions.

Ensure the discharge chute is clear. Reduce cutting height if the grass is very long. Ensure the bag is correctly attached.

Check the oil level (too high). Check for any fuel leaks.
