Important:
Position the curved ends of the blade
to point toward the machine housing.

Use a torque wrench to tighten the blade bolt to
82 N∙m (60 ft-lb).
Important:
A bolt torqued to 82 N∙m (60 ft-lb) is
very tight. While holding the blade with a block
of wood, put your weight behind the ratchet or
wrench and tighten the bolt securely. This bolt is
very difficult to overtighten.
