Alignment (Adjustments) (continued)
Step Two: Blade Square to Fence (Miter Alignment)
WARNING: To reduce the risk of injury from unex-
pected starting or electrical shock, do not plug the
saw in. The power cord must remain unplugged
whenever you are working on the saw.
Adjust Blade Square to Fence:
1. Lower the blade and engage the lock pin. Use a combi-
nation square. Place the square against the fence and
next to the blade as illustrated. Locate the square prop-
erly so it does not contact the set in the teeth of saw-
blade, giving an inaccurate reading. The sawblade
should contact the full length of the square.
2. If blade contacts full length of square, no alignment is
necessary, skip a-f below. If blade is not square to the
fence, follow the alignment procedure.
a. Loosen miter lock knob a half turn. The saw power
head should still be secured in the lowered position
by the lock pin.
CAUTION: To keep from losing control of the unit,
steady the base with one hand while loosening the
two bolts with the other hand.
b. With the unit securely resting on a large stable sur-
face, tilt the unit by lifting up on one side or the other
of the base. Using combination wrench supplied,
loosen the two miter arm cap head screws on the
underside of the turn table.
c. Return the saw to its normal resting position. Make
sure the miter lock knob is loose but do not release
the index spring.
d. Use the miter saw knob to move the table so that the
blade contacts the full length of the square. Watch
out for tooth set. Turn the miter lock knob clockwise
to lock saw square to fence.
e. Tilt saw as in Step b and tighten cap head screws.
f. Recheck blade squareness to fence and readjust if
necessary.
Adjust Miter Scale Indicator
1. Through the hole in front of the table insert, loosen the
Phillips screw that holds the Vernier indicator in place.
2. Reposition the indicator to align it with 0° mark, and
retighten screw.
Step Three: Pivot Adjustment
NOTE: This adjustment was made at the factory and nor-
mally does not require readjustment.
Arm Pivot Movement
1. Make sure the see through lower guard is rotated
closed and is resting against, or very close to, the rub-
ber stops. If not, see "Lubrication" section.
Bevel Pivot Movement/Adjustment
1. Check that miter saw bevels easily by loosening the
bevel lock handle and tilting the power head to the left.
NOTE: At least one thread of the pivot bolt should stick
out past the hex lock nut.

Cap Head Screws
2. If movement is tight or there is looseness in the pivot,
do the following adjustment procedure:

b. Turn the hex lock nut with a 3/4" or 19mm socket and
socket wrench.
c. Recheck bevel movement of the miter saw. Readjust
if necessary.
