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.

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.
