(27). Rotate the blade (25) slowly while
pressing the arbor lock until it fully seats
into its lock position.
4. Using the Torx wrench (Fig. 7, 41), loosen
the blade bolt by firmly turning it clockwise.
NOTE: This bolt has left-hand threads.
5. Remove the blade bolt and outer washer.
Carefully grab the blade. Slide the blade
(Fig. 13, 25) away from the inner washer

from the saw. Leave the inner washer on the
arbor shaft.

bevel positions. Lower the blade into the blade
slot and check for any contact with the base or
turntable structure. If the blade contacts base
or table, seek authorized service.
1. If a blade is currently installed, remove it
as described in "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 sup-
port ring of the inner washer (Fig. 12 and
Fig. 13).
3. Place the outer washer over the arbor shaft
and finger-tighten the blade bolt (counter-
clockwise). Check that the blade remained
on the inner washer's support ring.
4. Rotate the blade slowly while pressing the
arbor lock until it fully seats into its lock po-
sition.
5. Using the Torx wrench (Fig. 7, 41), firmly
tighten the blade bolt counterclockwise.
