14. Securely install the cover with the 2 wing nuts.
4.6 Maintaining the Blade
Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or
shredding the grass blades.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 5 & 7).
3. Drain the gasoline from the fuel tank.
4. Tip the lawn mower onto its right side (Fig. 18 and 19)
5. Inspect the Blade for sharpness and wear, especially where the flat and the curved
parts meet (Fig. 20A). Because sand and abrasive material can wear away the metal
that connects the flat and curved parts of the blade, check the blade before using the
lawn mower. If you notice a slot or wear (Fig. 20B and 20C), replace the blade.
NOTE: For the best performance, install a new blade before the cutting season
begins. During the year, file down any small nicks to maintain the cutting edge.
