10.5 Riving knife alignment
The riving knife must be aligned with the blade for
proper and safe operation of the table saw. This
has been set by the manufacturer, but should be
verified by the operator.
1. Disconnect machine from power source.
2. Install riving knife and tighten lever (H, Figure
18).
3. Place a straight edge against blade and riving
knife; it should lie flush against both surfaces.
See Figure 27.
4. If correction is needed, remove straight edge,
table insert, and riving knife and locate four set
screws (E, Figure 28) through the corner holes
of clamp block.
5. Rotate any of the four set screws as needed to
tilt the angle of the clamp block, and thus the
riving knife.
6. Install riving knife and verify the setting with
the straight edge. Make further adjustments as
needed.

10.6 Low profile riving knife
A low profile riving knife is included with your saw.
It mounts and adjusts in the same manner as the
standard riving knife. The low profile riving knife
sits just below top of blade and is used for making
non-through cuts. The blade guard is not used with
this knife, so extra precautions should be taken
during operation.
10.7 Trunnion adjustment
If backlash develops in the trunnion assembly, it
can be adjusted out using the screws (6mm hex
key) at front and back of cabinet (F, Figure 25
shows front screw). Front and rear trunnions
should receive the same amount of spring tension
from the screws.
10.8 Table to blade alignment
Refer to Figures 29 and 30.
The table has been squared to the blade by the
manufacturer and no adjustment is necessary now.
If cuts become inaccurate, check table-blade
squareness and correct if necessary. Use the miter
slot to do this:
1. Disconnect saw from power source.
2. Raise blade to maximum height.
3. Mark one tooth (A, Figure 29) with a grease
pencil and position the tooth slightly above the
top edge of table at the front.
4. Raise the miter gauge slightly out of its slot to
serve as a shoulder. Using a sliding square (B)
against the side of the bar, slide the scale over
until it touches the tip of the blade, and lock
the scale in position.
