the switch is in the OFF position and plug is not
connected to the power source outlet,
REMOVING {FIG. G, G-1, G-2)
1. Unplug the saw from the outlet.
2. Alow the miter saw to rise to the upright position.
Raise the lower blade guard (1) to the up position.
{Fig. G)
3. Loosen the cover plate screw (2) with a Phillips

Fig. G 1
8 . Remove the arbor bolt (4), outer blade collar ( 6 ), and
the blade (7). Do not remove the inner blade collar.
(Fig. G-2)
NOTE: Pay attention to the pieces removed, noting their
position and direction they face. Wipe the blade collars
clean of any sawdust before installing the new blade.
INSTALLING THE BLADE (FIG. G, G-1, G-2)
1. Install a 10 in. blade, 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) into the arbor
counterclockwise. (Fig. G-2)
IMPORTANT: Make sure the flats of the blade collars
are engaged with the flats on the arbor shaft.
6 . Locate the arbor lock (5) on the motor, below the
miter saw switch handle. (Fig. G-1)
7. Press the arbor lock, holding it in firmly while turning
the blade wrench clockwise. The arbor lock will
engage after turning the wrench. Continue to hold
the arbor lock in to keep it engaged, while turning
the wrench clockwise to loosen the arbor bolt.
Fig. G-1
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
it engages, continue to press the arbor lock in,
while tightening the arbor bolt securely. (Fig. F)
5. Rotate the cover plate (3) back until the slot in the
cover plate engages with the cover plate screw
(2). Tighten the screw with a Phillips screwdriver.
Lower the blade guard.
6 . Be sure the arbor lock is released so the blade
turns freely.
A WARNING
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 properiy
arranged. Lower the blade into the table and
check for any contact with the metal base or the
turn table.
