Briggs & Stratton 38510x50A Parts Manual

To change the oil, start by running the engine for a few minutes to warm it up. Turn off the engine and disconnect the spark plug wire. Remove the oil fill cap or dipstick. Place a pan under the oil drain plug, remove the plug, and allow the oil to drain completely. Replace the drain plug, fill with new oil, and check the oil level with the dipstick.
Use clean, fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use gasoline containing more than 10% ethanol.
Check the battery connections to ensure they are clean and tight. Verify the fuel level and ensure the fuel shutoff valve is open. Inspect the spark plug for wear or damage and replace if necessary. If the problem persists, consult the manual for further troubleshooting steps.
Ensure that the PTO switch is in the 'on' position. Check the drive belt for wear or damage. Inspect the PTO clutch and electrical connections for issues. If necessary, consult the manual for specific troubleshooting related to blade engagement.
Check the air filter every 25 hours of operation and replace it if it appears dirty or damaged. Replace the air filter at least once per season or more frequently if used in dusty conditions.
Consult the owner's manual for the recommended tire pressure, which is typically around 10-14 psi for front tires and 12-16 psi for rear tires. Regularly check and adjust the tire pressure to ensure optimal performance.
Remove the air filter and the carburetor cover. Use a carburetor cleaner spray to clean the inside of the carburetor. Make sure all openings and jets are free of deposits. Reassemble the carburetor and air filter. Consider consulting a professional if you are unfamiliar with carburetor maintenance.
Before storing, clean the tractor thoroughly, change the oil, add fuel stabilizer to the tank, and run the engine for a few minutes. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
Park the tractor on a flat surface, turn off the engine, and disengage the blades. Adjust the mower deck height lever to the desired position. Check that the deck is level from side to side and adjust if necessary by using the deck leveling adjusters.
First, check the engine coolant level and top it off if necessary. Ensure the radiator and cooling fins are clean and free of debris. Examine the fan belt for tension and wear. If the problem persists, consider servicing the cooling system.
