4. Non-thru cuts increase the chance of
kickback because the anti-kickback
pawls cannot always grab the irregular
workpiece surface. Use a featherboard.
See Cutting Accessories section on how
to make and use a featherboard.
2. The workpiece can be grabbed by the
saw blade and take off like a missile.
Anyone standing in the path of the
workpiece can be killed.
5. The workpiece can snag or hang up
on a fence with a kerr in it. The
workpiece can be thrown or pinch the
blade, causing kickback. Use solid fen-
ces when making rip cuts.
6. Wood cut with the grain can spring
the kerf closed, bind the blade, and
cause a kickback. Adjust spreader to
ride in the kerf and prevent the kerr
from closing on saw blade.
7. Composition materials, like particle
boards and plastics, may be cut on the
saw. Because these materials often
have a harder and more slippery surface
than wood, the anti-kickback pawls may
not stop a kickback. Place finished side
of workpiece down, roughest side of
workpiece up. Make anti-kickback pawls
and spreader adjustments. Stand out of
the path of workpiece.
Fig_ 119 Wrong Way Feed Safety Signs
Always feed the workpiece against the
direction of rotation of the blade, at the
infeed end of the blade.
,_ DANGER: Wrong Way Feed
Wrong way feed is feeding the
workpiece into the end of the blade with
pawls, the outfeed end. (Fig. 120) There
are two things that can happen if you
feed the workpiece into the outfeed end
of the saw blade:
Infeed End of: End
1. The workpiece can be grabbed by the
blade and pull your hands into the blade
before you can let go or pull back.
Fingers, hands or arms can be cut off.
