Assembly (continued)
6. Remove the arbor screw, arbor
washer, outer blade collar, and the
blade.
NOTE: Pay attention to pieces removed,
noting their position and direction they
face (see illustration). Wipe the blade col-
lars clean of any sawdust before installing
the new blades.
CAUTION: To reduce the risk of
cuts from extremely sharp teeth:
Wear gloves when installing or
removing sawblade.
See cautions in "Using Carbide Tipped
Blades" section concerning inspection,
use, and selection of carbide tipped and
other sawblades.
7. Install the new 12" blade (see recom-
mended accessory list). Make sure
the rotation arrow on the blade
matches the clockwise rotation arrow
on the upper guard. The blade teeth
should always point downward at the
front of the saw.
8. Install the outer blade collar, blade
washer and arbor screw. Press the
arbor lock and turn the combination
wrench or the 1/2" wrench counter
clockwise to secure the blade. Tighten
arbor screw using moderate force, but
do not overtighten.
9. Lower the lower blade guard until the
slot in cover plate rests all the way
down on the cover plate stop screw.
Tighten the screw with the Phillips end
of the combination wrench.
DANGER: Never use saw without
guard cover plate securely in
place. It keeps the arbor screw
from falling out if it accidentally
loosens, and prevents the spin-
ning blade from coming off the
machine.
10. Be sure the arbor lock is released so
the blade turns freely.

NOTE: The arbor lock can be damaged
by improper use. If the arbor lock will not
hold, lower the blade down on to a scrap
piece of wood positioned against the
fence. This will serve as an alternate lock-
ing means.
WARNING: Make sure the collars
are clean and properly arranged.
After installing a new blade,
make sure the blade clears the
table slot at the 0° and 45° bevel
positions. Lower the blade into
the table slot and check for any
contact with the base or turn
table structure. If blade contacts
table, seek authorized service.
If blade contacts insert, refer to "Align-
ment"section for adjustment.
