Figure 24 DECK CLEANING At least once a season and before storage, clean the underside of the mower deck to prevent build-up of grass clippings or other debris. 1. Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine. Disconnect spark plug wire. Refer to Engine Operator's Manual. 2. Turn mower on its side keeping the muffler side down and making sure that the air filter and the carburetor are facing up. Hold mower firmly. 3. Scrape and clean the underside of the deck with a suitable tool. Do not spray with water. IMPORTANT: Do not use a pressure washer or garden hose to clean your mower. These may cause damage to bearings, or the engine. The use of water will result in shortened life and reduce serviceability. 4. Put the mower back on its wheels on the ground. Blade Care WARNING Wait for the blade to stop completely before performing any work on the mower or to remove the grass catcher. Check blade stopping time is within 3 seconds. If blade does not stop within 3 seconds contact your Service Center. WARNING When removing the cutting blade for sharpening or replacement, protect your hands with a pair of heavy gloves or use a heavy rag to hold the blade. Annually check the mower blade mounting bolt torque: Min. 37.5 ft-lbs (50.8 N-m), Max. 50.0 ft-lbs (67.8 N-m). Periodically inspect the blade and blade adapter for bends or cracks, especially if you strike a foreign object or experience excessive vibration. Replace when necessary.
