Note:
The difference between the dimensions
obtained in steps 4 and 6 must not exceed 3 mm (1/8
inch).
Note:
If this dimension exceeds 3 mm (1/8 inch), the
blade is bent and must be replaced.
WARNING
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace a bent or damaged blade
with a new blade.
• Do not file or create sharp notches in the
edges or surfaces of the blade.
Removing the Blades
Blades must be replaced if a solid object is hit, if the
blade is out of balance, or if the blade 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 nonconformance with safety standards.
1. Hold the blade end using a rag or a thickly-padded
glove.
2. Remove the blade bolt, the curved washer, and the
blade from the spindle shaft (

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 104 ).
Note:
Maintain the original angle.
Note:
The blade retains its balance if the same amount
of material is removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (
Figure 105 ).
Note:
If the blade stays in a horizontal position, the
blade is balanced and can be used.
Note:
If the blade is not balanced, file some metal off
the end of the sail area only ( Figure 104 ).
