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.
