ASSEMBLY
 Rotate the miter table to 0
 Lock the miter lock lever by pushing it down.
 Remove the sliding miter fence by loosening the fence
screw and lifting the fence off the saw.
 Lay a framing square flat on the miter table. Place one
leg of the square against the fence. Slide the other leg
of the square against the flat part of saw blade.
NOTE: Make sure that the square contacts the flat part
of the saw blade, not the blade teeth.
 The edge of the square and the saw blade should be
parallel as shown in figure 17.
 If the front or back edge of the saw blade angles away
from the square as shown in figures 18 and 19, adjust-
ments are needed.
 Loosen the socket head screws that secure the fence to
the miter table. See Figure 16.
 Rotate the fence left or right until the saw blade is parallel
with the square.
 Retighten the socket head screws securely and recheck
blade-to-fence alignment.
Your saw has several scale indicators. After squaring adjust-
ments have been made, it may be necessary to loosen the
indicator screws and reset them to zero. See Figure 20.
