Adjustment Instructions; Adjusting Fence Squareness - Craftsman 21217 - 12 in. Miter Saw Operator's Manual

InstallingBlade
(Fig. G, H, I)
1. Install a 12 in. blade with a 5/8 in. arbor (or a 1 in.
arbor with a 5/8 in. reducer as saw comes with)
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 (9). Thread the arbor bolt (4) onto the arbor
(9) in a counterclockwise direction. (Fig. I)
iMPORTANT: Make sure the flats of the blade
collars are engaged with the flats on the arbor shaft.
Also, the flat side of the blade 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 counterclockwise. When arbor lock
engages, continue to press it 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). While holding the lower blade
guard, tighten the screw with a Phillips screwdriver.
(Fig. G) 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. G)
7. Be sure the arbor lock is released so the blade turns
freely.
_ WARNING I
o To avoid injury, never use the saw without the
cover plate secure in place, it keeps the arbor
bolt from failing out if it accidentally loosens, and
helps prevent the spinning blade from coming off
the saw.
o 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.
ADJUSTMENT iNSTRUCTiONS
,_ WARNING ]
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.
ADJUSTING FENCE SQUARENESS (FIG. J)
1. Lower the cutting arm and lock in position.
2. Using a square, lay the heel of the square against the
blade, and the rule against the fence (2) as shown.
Check to see if the fence is 90 ° to the blade.
3. If not, loosen the three fence locking bolts (1), adjust
fence 90 ° to the blade and tighten the fence locking
bolts.
CAUTION: If the saw has not been used recently,
recheck blade squareness to the fence and readjust
if needed.

MITER SCALE (FIG. K)
The miter scale assists the user in setting the desired
miter angles from 47 ° left to 47 ° right. The miter saw
table has nine of the most common angle settings with
positive stops at 0°, 15 °, 22.5 °, 31.6 ° and 45 °. These
positive stops position the blade at the desired angle
quickly and accurately.
To Adjust the Angles:
1. Unlock the miter table by turning the miter handle (1)
counterclockwise.
2. While holding the positive-stop locking lever (2)
down, grasp the miter handle and rotate the miter
table left or right to the desired angle.
3. If the desired angle is one of the nine positive stops,
release the positive-stop locking lever, making sure
the lever snaps into position, and then secure by
tightening the miter handle.
4. If the miter angle desired is not one of the nine
positive stops, simply lock the miter table into position
by turning the miter handle in the clockwise direction.
To Adjust the indicator:
1. Position the miter table at zero degrees.
2. Loosen the pointer screw (4) and adjust the indicator
to the 0° mark on the miter scale (3) and retighten
the screw.
