Making Adjustments to Your Saw
To check the height of the riving knife relative to the blade, lower the blade elevation until the lower limit stop is
engaged. Place a ruler or another straight edge on the table so that it lies across the width of the table insert
and directly above the tip of the riving knife. Raise the blade elevation until the tip of the riving knife just comes
in contact with the straight edge or ruler (see Fig. 125).
Now measure the distance from the top of the table to the top of the blade. If the height of the riving knife is set
correctly, the saw blade should be approximately 1 mm above the table. If the distance is approximately 1 mm,
no further adjustments are necessary.

If the height of the riving knife is not correct, use the elevation handwheel to set the top of the blade to 1 mm
above the top of the table. Next, remove the table insert and loosen the two vertical positioning bolts shown in
Fig. 122 using the included 5 mm hex key. Loosen the bolts just enough so that you can move the clamp up
and down on the clamp mounting bracket.
Next, adjust the position of the clamp up or down to set the height of the riving knife. You can also rotate the
clamp forward or backward so that the arc on the front edge of the riving knife is concentric with the blade.
When the riving knife is correctly positioned, tighten the two vertical positioning bolts just enough to hold the
clamp in position and reinstall the table insert. Check to make sure the tip of the riving knife is level with the
table. Repeat the adjustment if necessary. Once the vertical alignment of the riving knife is correct, fully tighten
the two vertical positioning bolts on the clamp.
In some cases, adjusting the vertical alignment may cause the spacing between the front edge of the riving
knife and the teeth of the blade to be incorrect. If this happens, repeat the steps explained above to adjust the
gap between the front edge of the spreader and the teeth of the blade so that it is 4-7 mm.
Once the clamp has been properly positioned, further adjustment should not be necessary. Both the spreader
and riving knife will now automatically align when installed in the clamp.
