the blades at the same position as in step

The difference between the dimensions obtained in
steps
3 and 4 must not exceed 3 mm (1/8 inch). If this
dimension exceeds 3 mm (1/8 inch), the blade is bent
and must be replaced; refer to
Removing the Blades
(page 46) and Installing the Blades (page 47) .
WARNING
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace bent or damaged blade
with a new blade.
• Never file or create sharp notches in the
edges or surfaces of blade.
Removing the Blades
Blades must be replaced if a solid object is hit, if the blade is
out of balance or is bent. To ensure optimum performance
and continued safety conformance of the machine, use
genuine Toro replacement blades. Replacement blades made
by other manufacturers may result in non-conformance with
safety standards.
1. Hold the blade end using a rag or thickly-padded glove.
