Installing Blade (Fig. H, I, J, K)
Unplug 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 blade collar (6) against
the blade and on the arbor. Thread
the arbor bolt (4) onto the arbor in a
counter-clockwise direction. (Fig. K)
IMPORTANT: Make sure the flats of
the blade collars are engaged with
the flats on the arbor shaft. Also, the
flat-side of the 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 firmly while turning the blade
counter-clockwise. When it engages,
continue to press the arbor lock
in while tightening the arbor bolt
securely. (Fig. J)
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 star-head screwdriver. (Fig.
H, I) NOTE: The lower blade guard
must be raised to the upright position
to access the cover plate screw.
6. Lower the blade guard (1), and verify
that the operation of the guard does
not bind or stick. (Fig. H)
7. Be sure the arbor lock is released so
the blade turns freely.
iAI_kWARNING i
e To avoid injury, never use the
saw without the cover plate
secured 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.
e Make sure the collars are clean
and properly arranged. Lower
the blade into the lower table,
and check for any contact with
the metal base or the miter
table.
e To avoid injury from an
accidental start, make sure the
switch is in the off position,
and the plug is not connected
to the power source.
