FINAL CALIBRATION
As with any table saw fence,
accurate calibration and alignment require that
the saw blade be aligned parallel to the miter
slots. If you are uncertain about your saw
blade/miter slot alignment, consult your table
saw’s owner’s manual for information on how to
check and set this important alignment.
Calibration –
Right side of saw blade
Align fence parallel to
miter slot and tighten
Ultra’s mounting screws
Unlock the carriage clamp, then slide the
fence up to the nearest miter slot and clamp
in place. Loosen the (4) screws that secure
the Ultra’s base to the base support bars and
align the fence parallel to the miter slot. See
. Make sure during this alignment that
the fence glides remain flush with the rails.
Retighten the (4) screws. Now unlock and
slide the carriage forward far enough to allow
access to the (2) phillips head screws in the
middle of the Ultra’s base and tighten these in
place.
If it becomes necessary to realign
the fence in the future, make sure to loosen all
(6) base mounting screws.
Zero fence to saw blade
With the table saw unplugged, raise the
saw blade about 2" and slide the fence forward
until just before it contacts the blade (to within
less than
1
⁄
32
"). Place your Ultra in the micro
adjust mode as described on page 7 of your
Ultra’s owner’s manual and micro adjust the
fence forward until it “kisses” the saw blade,
. Release the micro adjust lever and lock
the carriage in place.
Note: After micro adjusting, re-zero the
scale on the micro adjust knob by rotating
the scale (not the knob) to return to zero
under the micro cursor.
Set scale position
With the Ultra still locked at the “zeroed”
position set above, lift one end of the stainless
steel scale from the magnetic track and slide
the scale to position 0" under the hairline cursor.
. Lower the scale back onto the
magnetic track. If you want, you can also slide
the two-piece lexan scale to agree with the
stainless steel scale. Make sure the
overlapping ends of the scales are aligned at
16".
