Spreader or Riving Knife
Alignment
Checking Alignment with Blade
The blade guard spreader and riving knife must be aligned
with the blade when installed. If the spreader/riving knife
is not aligned with the blade, then the workpiece will
before forced sideways during the cut, which will increase
the risk of kickback.
Tool Needed Qty
Straightedge .....................................................1
To check the spreader/riving knife alignment, do these
steps:
1. DISCONNECT SAW FROM POWER!
2. Raise the saw blade to the maximum height so you
have easy working access.
3. Place the straightedge against the side of the blade
and spreader/riving knife at the top and bottom, as
illustrated in Figure 100. The spreader/riving knife
should be parallel with the blade along its length
at both positions, and in the "Alignment Zone," as
shown in Figure 101.
— If the spreader/riving knife is not parallel with
the blade and inside the alignment zone, then it
needs to be adjusted. Proceed to the Adjusting
Alignment instructions on the next page.
4. Remove the spreader/riving knife and place it on a
flat surface and check to see if the spreader/riving
knife lays evenly along its length.
— If the spreader/riving knife does not lay evenly,
proceed to Adjusting Bent Spreader/Riving Knife
on the next page.
