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.
•
Never file or create sharp notches in the
edges or surfaces of the blade.
A.
If the difference is greater than 3 mm (1/8 inch),
replace the blade with a new blade; refer to
Removing the Blades (page 37)
and
.
Note:
If you replace a bent blade and the
dimension obtained continues to exceed 3 mm
(1/8 inch), the blade spindle could be bent.
Contact an Authorized Toro Dealer for service.
B.
If the variance is within constraints, move to the
next blade.
6.
Repeat this procedure on each blade.
Removing the Blades
Replaces a blade if it hits a solid object, if it is out of balance,
or if it 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.
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 (
).
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 (
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 (
