the guard clamp screw and rotating the guard -{
so that the "nose" just clears the workpiece as zt

This adjustment is necessary to:
1) Protect the operator from accidentally con-
tacting the sawblade from the "infeed"
direction.
2) Prevent the workpiece from being lifted
from the table by the sawblade thus mini-
mizing lifting or fluttering (particularly with
thin and/or light workpieces).
b.
3) Minimizesawdust from being thrown toward
the operator.
The anti-kickback and spreader assembly is
adjustable to accommodate the thickness of
the board being ripped.
For ripping, the anti-kickback and spreader
assembly is positioned by loosening the wing
screw and, with the tab provided, positioning
the anti-kickback and spreader assembly until
the pawls assume approximately the position
shown. Tighten the wing screw.
Make sure by trial - without saw running -
before starting the cut that the anti-kickback
pawls will stop a kickback once it nas started.
Insert workpiece alongside spreader under
outer set of pawls by approaching pawls in the
feed direction. Push workpiece sharply in the
direction of a kickback (opposite direction of
feed). Readjust pawls if they do not stop the
kickback motion by biting into the workpiece.
If the workpiece does not feed smoothly under
the pawls, the spreader may be set too deeply.
Loosen the wing screw, raise the spreader
slightly, retighten the screw, recheck work-
piece in-feed and kickback pawl function.
These adjustments when properly made will:
1) Reduce possibility of kickbacks by prevent-
ing the kerf from closing on the sawblade.
2) Prevent "wrong-way feed". "Wrong-way
feed" is feeding the workpiece - when the
sawblade is in a rip position - into the out
feed side of the cutting tool (sawblade,
dado, molding head, etc.), the side contain-
ing the anti-kickback pawls/spreader. This
can be extremely hazardous because the
sawblade may grab the workpiece and throw

it violently toward the nose of the guard
(infeed side of the tool) possibly pulling
your hand with it before you can react. See
Danger label on outfeed side of the guard
just below the dust elbow.
"Wrong-way feed" differs from kickback". A
"kickback" is generated by the sides (one or
both) of the teeth, because of binding
between the fence (heel), pinching of the
sides of the sawbtade (failure to use
spreader), a dull blade, and/or inadequate
set of teeth of sawblade.
Act as a partial guard regarding accidental
contact with the sawblade at the outfeed
side when ripping.
For crosscutting the anti-kickback and spreader
assembly is positioned by loosening wing screw.
With the tab provided position the anti-kickback
spreaders assembly until the pawls just clear the
workpiece or fence which ever is higher.
