TO ADJUST THE MITER BASE
See Figure 26.
Remember: Check all settings before loosening screws for
the following procedures. Once screws have been loosened,
these settings must be reset.
Unplug the saw.
Set the miter fence at 0˚ then securely tighten the
lock knob.
Push the sliding miter table to the back and loosen the
right-front screw from beneath the table saw cabinet.
Loosen the nylock nut beneath the front left eccentric
screw.
Place one side of a framing square firmly against the miter
fence and the other side against the saw blade.
Using a flathead screwdriver, turn the eccentric screw
until the miter fence and the blade are square.
Hold the eccentric screw in place with the screwdriver
and tighten the nylock nut securely.
Retighten the front right-hand screw.
TO CHECK MITER FENCE ALIGNMENT
See Figure 27.
The miter fence must be perpendicular to the blade when
set at zero degrees.
Set the miter fence (H) at 0°. Miter indicator (I) should be
set precisely on 0° and secured in place with adjusting
clamp (J).
NOTE: The quick-stop is not necessary for this checking
procedure. However, you may want to check and adjust it
to 0° at this time. See the To Adjust Quick-Stop section
that follows.
Place a framing square (G) firmly against the miter fence
(H), with the other side against the blade (E).
Check whether the miter fence and blade are square with
each other. With the framing square against the miter
fence there should be no gap from the front to the rear
of the blade.
If a gap exists, the miter fence may be out of square.
Rotate the blade and recheck. If there is a consistent gap
between the front and rear of the blade, the miter table
needs aligning. Follow the adjustment procedures that
follow.
