To start the mower, ensure the fuel valve is open, the throttle is in the 'choke' position for cold starts, and the blade control lever is engaged. Pull the starter handle briskly.
Use SAE 30 oil for temperatures above 32°F (0°C). For temperatures below 32°F, use SAE 5W-30 to ensure proper lubrication.
Sharpen the mower blade every 20-25 hours of use, or more frequently if you mow over rough surfaces.
After each use, scrape off grass clippings and debris from the underside of the deck using a plastic scraper to maintain optimal performance.
Check for fuel in the tank, ensure the spark plug is connected, and that the air filter is clean. If these are fine, inspect the ignition system.
Regular maintenance includes checking the oil level, cleaning the air filter, inspecting the blade, and tightening any loose bolts.
To adjust the cutting height, use the height adjustment levers located near each wheel. Set all wheels to the desired height.
Excessive vibration may be due to a damaged blade or loose parts. Inspect and replace the blade if necessary, and tighten any loose components.
To replace the air filter, remove the air filter cover, take out the old filter, and insert a new filter, ensuring it is seated properly before securing the cover.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol blends higher than E10 to prevent engine damage.
