Adjusting Crosscut Rulers
The panel saw comes with one rip (vertical) ruler
and two crosscut (horizontal) rulers. The rip ruler is
preset at the factory. The crosscut rulers should be
checked and, if necessary, adjusted before
operating the saw. Also, they may have to be
adjusted after every blade change. With the blade
installed, do the following:
1. Remove blade guard.
2. Loosen carriage locking knob and lower
carriage down to the rulers.
3. Using a square that measures at least 14" on
one side, line up one edge of the square with
the tips of the saw blade, and the other edge
with the crosscut ruler. See Figure 16.
4. If these are out of square, loosen the three
bolts that hold the angle bracket to which the
scale is attached. Slide the angle bracket so
that its measure matches the measure on the
square.
5. Repeat the above steps for the crosscut ruler
on the other side.
6. Make a test cut to verify that the ruler is lined
up correctly.
Alignment
If the saw ever needs realignment, it should be
performed in the following order:
1. Align rollers.
2. Align guides perpendicular to rollers.
3. Align blade parallel to guides.
To ensure accuracy over the full movement of the
saw, construct a test square as follows, (Figure
17):
Use a 6-foot metal ruler and two 4-foot metal rulers
(using the 3-, 4-, and 5-ft. measurements ensures
squareness). Drill holes and attach the rulers with
pop rivets or small nuts and bolts.
The 6-foot ruler is used to check squareness of the
rollers. The 4-foot ruler is used to check
squareness of the guide tubes.
