"Removing Blade" on page 20.
2. Carefully handle the new blade. Check that the rotation
arrow on the blade matches the rotation arrow on the
upper guard. Slide the blade up and between the sides
of the chip deflector and over the arbor shaft. Move the
blade so its arbor hole goes around the support ring of
the inner washer (Fig. 12 and Fig. 13).

tighten the blade bolt (counterclockwise). Check that the
blade remained on the inner washer's support ring.

it fully seats into its lock position.

blade bolt counterclockwise.
NOTE: This bolt has left-hand threads. Do not over tight-
en. A T30 Torx key may be used as an alternate.
