What routine maintenance should I perform on the Craftsman STD533710 lawn mower?

Perform regular service and adjustments as outlined in the Maintenance Schedule located on page 18. Regular checks should include brake operation, tire pressure, operator presence interlock systems, loose fasteners, mower blade sharpness or replacement, and lubrication levels. Additionally, remove built-up grass and debris from the mower housing after each use. (Page 2)
