Briggs & Stratton 31200x11B Parts Manual

To start the tractor, ensure the parking brake is engaged, the PTO is off, and the throttle is set to choke for a cold engine. Turn the ignition key to start and release once the engine runs.
Use SAE 30 oil for temperatures above 40°F (4°C) and SAE 10W-30 for varying temperature ranges. Always check the oil level before each use.
The air filter should be checked every 25 hours of operation and replaced if dirty or damaged. Regular maintenance ensures optimal performance.
Check the fuel level, ensure the spark plug is clean, and verify that the battery is charged. Also, make sure the safety switches are properly engaged.
Regular maintenance includes checking and changing the oil, inspecting the air filter, cleaning the engine cooling fins, and tightening any loose bolts or connections.
Ensure the blades are sharp and balanced, check tire pressure for consistency, and verify the deck is level. Adjust as necessary for even cutting.
The recommended tire pressure is typically around 10 PSI for the rear tires and 14 PSI for the front tires. Check the manual for specific details.
Remove the air filter and spray carburetor cleaner into the intake. For deep cleaning, disassemble the carburetor and clean all parts thoroughly, then reassemble.
Possible causes include blocked cooling fins, low oil levels, or a clogged air filter. Clean and inspect these components regularly to prevent overheating.
Clean the tractor, change the oil, remove the battery, add fuel stabilizer, and store in a dry, covered area to protect it from harsh winter conditions.
