5.
Measure from the tip of the blade to the flat
surface
(Figure
90).
Note:
The variance should be no more than
3 mm (1/8 inch).

A.
If the difference between A and B is greater
than 3 mm (1/8 inch), replace the blade with
a new blade; refer to
(page 62)
and
63).
Note:
If a bent blade is replaced with a
new blade, and the dimension obtained
continues to exceed 3 mm (1/8 inch), the
blade spindle could be bent. Contact an
Authorized Service 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
Installing the Blades (page
Removing the Blades
Replace the blades if they hit a solid object, or if the
blade is out of balance or bent.
1.
Place a wrench on the flat of the spindle shaft or
hold the blade end using a rag or thickly padded
glove.
2.
Remove the blade bolt, bushing, and 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.
1. Sharpen at original angle.
2.
Check the balance of the blade by putting it on a
blade balancer
