the other hand to align the holes in the blade with the through holes in the inner flange
(Fig. 22).
7. Place a metal rod (e.g., a 3.5'' length screw bit) with diameter less than 1/4'' (6.35mm) into
the aligned holes to act as a stabilizer. Place another metal rod (e.g., a 3.5'' length screw
bit) with diameter of 5/16'' (8mm) into the fixing hole to act as another stabilizer (Fig. 23).

pieces to be thrown from the mower.
If the blades are found to be bent, take the lawn mower to an authorized SKIL service center
for inspection.
