Checking Alignment
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 kick-
back.
Tools Needed Qty

To check the spreader/riving knife alignment:
1. DISCONNECT THE SAW FROM POWER!
2. Raise the saw blade to the maximum height
so you have easy working access.
3. Place the straightedge against the top and
bottom of blade and spreader/riving knife,
as shown in Figure 114. The spreader/riv-
ing knife should be be parallel with the blade
along its length at both positions, and it will
be in the "Alignment Zone," as shown in
Figure 115.
