kerf and pinching the blade.
C. Cutting off a cantilevered or overhanging piece of material from
the bottom up in a vertical direction. The falling cut off piece can
pinch the blade.
D. Cutting off long narrow strips (as in ripping). The cut off strip can
sag or twist closing the kerf and pinching the blade.
E. Snagging the lower guard on a surface below the material being
cut momentarily reducing operator control. The saw can lift partially
out of the cut increasing the chance of blade twist.
2. IMPROPER DEPTH OF CUT SETTING ON SAW
Using the saw with an excessive depth of cut setting increases
loading on the unit and susceptibility to twisting of the blade in the
kerf. It also increases the surface area of the blade available for
pinching under conditions of kerf close down.
3. BLADE TWISTING (MISALIGNMENT IN CUT)
A. Pushing harder to cut through a knot, a nail, or a hard grain
area can cause the blade to twist.
B. Trying to turn the saw in the cut (trying to get back on the marked
line) can cause blade twist.
C. Extended reach or operating saw with poor body control (out of
balance), can result in twisting the blade.
D. Changing hand grip or body position while cutting can result in
blade twist.
E. Backing unit up to clear blade can lead to twist if not done
carefully.
4. Materials that require extra attention
A. Wet lumber
