surface (Figure 93).
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 67) and
68).
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.
