Making Adjustments to Your Saw
Aligning the Blade Elevation Assembly
The following blade elevation alignment procedure assumes the blade has already been aligned with the tilt
axis. If the blade has not been aligned with the tilt axis, fi rst follow the procedure in the section “Aligning the
Blade to the Tilt Axis” on page
69 and then continue with aligning the blade elevation assembly.
The blade elevation assembly controls the motion of the blade as it is raised and lowered. Aligning the blade
elevation assembly ensures that there is minimal lateral movement of the blade as it is raised and lowered.
Although all table saws suffer from some lateral blade movement due to tolerance stack-ups in machining, only
SawStop cabinet saws allow you any adjustment to minimize this problem.
The SawStop ® Professional Cabinet Saw uses a vertical slide elevation design for ultra smooth operation
and rigidity. As shown in Fig. 103, the blade and arbor block are mounted on a large cast iron base called the
elevation plate. The elevation plate slides up and down on two shafts that are attached to the rear trunnion.
This blade elevation assembly is aligned by adjusting the orientation of the secondary shaft so that it is parallel
to the primary shaft. If the shafts are not parallel the blade will rotate about a vertical axis as the blade is raised
and lowered. When the blade elevation assembly is aligned, the blade will remain parallel to the miter slots with
minimum lateral movement as it is raised and lowered.
First verify that the table is aligned. With the blade fully elevated and at a 0º tilt angle, measure the parallelism
of the blade relative to the miter slots in the table as described above in the section named “Aligning the Table”
beginning on page
65 .
