REMOVING - cont'd
8. Remove the arbor bolt (4), the outer blade collar (6),
and the blade (7) with the 5/8" reducer. Do not
remove the inner blade collar. (Fig. I)
9. Raise the lower clear plastic blade guard (1) to the
upright position (Fig. G) to remove the blade.
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" blade has a 1" arbor hole with a
5/8" reducer to mount onto the saw.

INSTALLING BLADE (Fig. G, H, I)
Un-plug the miter saw before changing/installing the
blade.
1. Install a 12" blade with a 5/8" arbor (or a 1" arbor with
a 5/6" 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 outer blade collar (6) against the blade and
on the arbor. Thread the arbor bolt (4) on the arbor
(Fig. I} 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.
3. Place the blade wrench on the arbor bolt.
4. Press the arbor lock (5), holding it in firmly while
turning the blade wrench counterclockwise. When the
arbor lock engages, continue to press the arbor lock
in while tightening the arbor bolt securely. (Fig. H)
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). Tighten the screw with a
Phillips screwdriver. (Fig. G)
6. Be sure the arbor lock is released so the blade turns
freely by spinning the blade until the arbor lock
disengages.
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 outlet. 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.
ADJUSTING FENCE SQUARENESS (Fig. J)
1. Set the bevel and miter angles at zero degrees.
2. Lower and lock the cutting head into position.
3. Using a square, lay the heel of the square against the
blade, and the rule against the fence (2) as shown.
NOTE: Be sure to rest the square against the body of
the blade and not against the teeth of the blade.
4. If the blade is not 90 ° to the fence, loosen the three
fence locking bolts (1).
5. Adjust the fence 90 ° to the blade and re-tighten the
three fence locking bolts.
CAUTION: If the saw has not been used recently,
recheck blade squareness to the fence and readjust if
needed.
