3. Place the blade wrench on the
arbor bolt.
4. Press the arbor lock (5), holding
it in firmly while turning the blade
counterclockwise. When it engages,
continue to press the arbor lock
in, while tightening the arbor bolt
securely. (Fig. M)
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. L) 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.
L).
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.
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. N
INSTALLING BLADE (FIG. L, M, N)
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.
N) in a counterclockwise direction.
IMPORTANT: Make sure the flats
of the blade collars are engaged
with the flats on the arbor shaft.
Also, the flat-side of the arbor collar
must be placed against the blade.
