TO REPLACE BLADE
•Place blade on shaft so that the blade edges are parallel with the flat sides of the shaft. Make sure you place the blade so that its cutting edges will face the ground when the mower is running.
•Place plastic insulator washer on shaft so that two of the washer’s raised edges fit over the edges of the blade.
TO SHARPEN BLADE
•Keep blade sharp for best mower performance. A dull blade does not cut grass evenly.
•Wear proper eye protection.
•Sharpening the blade twice during a mowing season is usually sufficient under normal circumstances. Sand causes the blade to dull fast. If your lawn has sandy soil, more frequent sharpen- ings are required.
•Replace bent or damaged blade immediately.
•To sharpen blade:
•Make sure blade remains balanced.
•Sharpen blade at the original cutting angle.
•Sharpen cutting edges on both ends of blade, removing equal amounts of material from both ends.
•Secure blade in a vise as shown in figure below.
•Wear safety glasses and be careful not to cut yourself.
•Carefully file the cutting edges of the blade with a fine tooth file or sharpening stone.
