2. Rotate the opposite ends of the blades forward.
3. Measure from a level surface to the cutting edge of the
blades at the same position as in step 1 above. The
difference between the dimensions obtained in steps 1
and 3 must not exceed 1/8 inch (3 mm). If this
dimension exceeds 1/8 inch (3 mm), the blade is bent
and must be replaced; refer to Removing the Blades and
Installing the Blades, page 30.
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.
Warning
Removing the Blades
The 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.
Hold the blade end using a rag or thickly-padded glove.
Remove the blade bolt, spring disk and blade from the
spindle shaft (Fig. 29).
Contact with sharp blade can cause serious injury.
Wear gloves or wrap sharp edges of the blade with
a rag.

Sharpening the Blades
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening
blade.
Warning
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 30). Maintain the original angle. 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 (Fig. 31). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off of the end of
the sail area only (Fig. 29). Repeat this procedure until
the blade is balanced.
