REMOVING AND INSTALLING BLADE
(FIGURE 9, 10, 11)

1. RELEASE SWITCH LEVER TO TURN MOWER OFF, WAIT FOR THE BLADE TO STOP, AND UNPLUG MOWER. THEN TURN THE MOWER OVER FOR ACCESS TO THE BLADE.

2. Use a piece of 2x4 wood (about 2 feet long) to keep blade from turning while removing flange nut.

3. Wear gloves and proper eye protection. Be careful of sharp edges of blade. Position wood and remove flange nut as shown in Figure 9.

4. Remove square metal blade spacer, square plastic blade insulator, and blade (Figure 10). Examine blade insulator for damage and replace if necessary.

5. When replacing sharpened or new blade on shoulder of fan, make sure the “GRASS SIDE” on the blade will be facing the ground when the mower is returned to its normal upright position. After installing blade, place blade insulator on blade such that the raised lips on one side engage the edges of the blade. Then install the blade spacer so that it sits inside the raised lips on the other side of the blade insulator. Be sure to align the flats in the hole of the blade spacer with the flats of the shaft, rotating the blade and blade insulator together as necessary. Position piece of wood to keep blade from turning (Figure 11). Install flange nut with the flange against the blade spacer and securely tighten.
