e) Inspect blades and sharpen or replace as required.
f) If blade removal is necessary, be careful for the sharp cutting edges of the
blades.
g) Re-install the blades (if they were removed) by placing a block of wood
between the front or rear baffles and the blade then torquing the blade
bolts to 115-120 ft. lbs. Be sure the spring disk washer cone is installed
toward the bolt head (See Figure 4).
POTENTIAL HAZARD

blade bolts can be dangerous.
WHAT CAN HAPPEN
