6. Remove the arbor screw, arbor washer,
and outer blade collar.
NOTE: The Exactline™ Laser System
will replace the outer blade collar.
Retain the outer blade collar, arbor
screw and blade washer to operate the
saw when the laser system is not
mounted.
7. Place the laser system onto the saw
arbor, aligning the double "D" flats in the
laser system with the flats on the arbor.
Press the arbor lock and turn the com-
bination wrench counterclockwise to
secure the blade. Tighten arbor screw
using moderate force, but do not over-
tighten.
8. 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 the saw
without guard cover plate
securely in place. It keeps the
arbor screw from falling out if it
accidentally loosens, and pre-
vents the spinning blade from
coming off the machine.
9. 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.
