WARNING
!
NOTE: Pay attention to the pieces
removed, noting their position and
direction they face. Wipe the blade
collars clean of any sawdust before
installing a new blade. Also, the 12 in.
blade has a 1 in. arbor hole with a 5/8
in. reducer (8) to mount onto the saw.
Fig. M
INSTALLING BLADE (FIG. K, L, M)
Un-plug the miter saw before
changing/installing the blade.
1. Install a 12 in. blade with a 5/8 in.
arbor (or a 1 in. arbor with a 5/8 in.
reducer) making sure the rotation
arrow on the blade matches the
clockwise rotation arrow on the
upper guard, and the blade teeth
are pointing downward.
2. Place the arbor collar (6) against
the blade and on the arbor. Thread
the arbor bolt (4) on the arbor (Fig.
M) in a counterclockwise direction.
IMPORTANT: Make sure the fl ats of
the blade collars are engaged with
the fl ats on the arbor shaft. Also, the
fl at-side of the arbor collar must be
placed against the blade.
3. Place the blade wrench on the arbor
bolt.

4. Press the arbor lock (5), holding
it in fi rmly while turning the blade
counterclockwise. When it engages,
continue to press the arbor lock
in, while tightening the arbor bolt
securely. (Fig. L)
5. Rotate the cover plate (3) back to its
original position until the slot in the
cover plate engages with the cover
plate screw (2). While holding the
lower blade guard, tighten the screw
with a Phillips screwdriver. (Fig. K)
NOTE: The lower blade guard must
be raised to the upright position to
access the cover plate screw.
6. Lower the clear retractable blade
guard (1) and verify the operation of
the guard does not bind or stick
(Fig. K).
7. Be sure the arbor lock is released
so the blade turns freely by spinning
the blade until the arbor lock
disengages.
● To avoid injury, never use the
saw without the cover plate
secure in place. It keeps the
arbor bolt from falling out if it
accidentally loosens, and helps
prevent the spinning blade from
coming off the saw.
● Make sure the collars are clean
and properly arranged. Lower the
blade into the table and check for
any contact with the metal base
or the turn table.
