b) Lift deck and secure in raised position as stated in Section 4.1.4.
c) Inspect blades and sharpen or replace as required.
d) Re-install the blades (if they were removed) in the following order (See Fig. 7):
1) Install bushing through blade with bushing flange on bottom (grass) side of
blade.
2) Install bushing/blade combo into spindle.
3) Install blade bolt and spring disc washer. Be sure the spring disc washer
cone is installed towards the bolt head. Place a block of wood between

bushing, spring disc washer, and blade bolt supplied with the unit. Failure to use all
original components and assembled as shown will increase the risk of a blade bolt
becoming loose or weak after striking a foreign object.
