Important:
Position the curved ends of the
blade to point toward the machine housing.
6.
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.
