To engage the self-propel function, hold the drive lever against the handlebar. Release the lever to disengage the drive.
The Mountfield SP42 features a central cutting height adjustment lever. To change the cutting height, lift the lever and move it to the desired position. There are 6 cutting height positions available, ranging from 22mm to higher settings.
To stop the engine, release the engine brake lever. The engine will automatically shut off.
Regular maintenance is crucial for the longevity and performance of your lawnmower.
Check the engine oil level before each use. Change the engine oil after the first 5 hours of operation, and then every 25 hours or annually, whichever comes first. Refer to the engine manual for the correct oil type and procedure.
Clean the air filter every 25 hours or more frequently in dusty conditions. Replace if damaged or excessively dirty.
Inspect the spark plug annually or every 50 hours. Clean or replace as needed. Ensure the gap is set correctly.
Regularly inspect the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Have the blade sharpened or replaced by a qualified service technician if necessary. Always disconnect the spark plug before working on the blade.
For long-term storage, ensure the fuel tank is empty or treated with a fuel stabilizer. Clean the mower thoroughly and store it in a dry, protected area.
