Mountfield SP185 user manual

The Mountfield SP185 lawnmower typically requires a specific type of oil known as SAE 30 motor oil.

The Mountfield SP185 lawnmower requires approximately 0.5 liters of oil.

There could be multiple reasons why your Mountfield SP185 mower is difficult to start. Some possible causes include:
1. Fuel issues: Ensure that the tank has enough fuel and that the fuel is fresh and not old or contaminated. Also, check that the fuel valve is open if your mower has one.
2. Spark plug problems: Check the spark plug to make sure it is clean, properly gapped, and in good condition. Replace it if necessary.
3. Carburetor issues: A clogged or dirty carburetor can prevent the proper mixture of fuel and air, making starting difficult. Cleaning or rebuilding the carburetor may be necessary.
4. Air filter blockage: An excessively dirty or clogged air filter can restrict air flow, making it harder to start the mower. Clean or replace the air filter as needed.
5. Ignition system problems: Faulty ignition components, such as a faulty ignition coil or a damaged spark plug wire, can prevent the spark from reaching the spark plug, causing difficulty in starting the engine.
6. Engine flooding: If you repeatedly try to start the mower without success, it can result in flooding the engine with excess fuel. In such cases, wait for a few minutes to allow the excess fuel to evaporate before trying again.
If you're unable to diagnose or resolve the issue on your own, it's recommended to consult a professional mechanic or authorized service center for further assistance.
