GUARD CLEARANCE
1.
The
blade guard
is positioned
by
loosening
the guard
clamp
screw and rotating
the guard so that the nose just
clears the workpiece
as shown.
This is necessary:
to protect
operator
from
accidentally
contacting
the
sawblade
radially
from
the Infeed
direction.
to
hold
down
the
workpiece
against
the
table
-
minimizing
lifting
or
fluttering
(particularly
thin
and/or
light
workpieces);
to minimize
sawdust
thrown
toward
the operator.
- to
minimize
the
possibility
of a thin
pusher
board
riding
up on top of the workpiece
with
loss of control
of workpiece.
2.
The antikickback
and spreader
assembly
is used during
ripping
operations
and
is adjustable
to
accommodate
the thickness
of the board
being
ripped.
A wing
screw
in the guard secures the assembly.
These adjustments
are necessary:
Antikickback
-- to stop a kickback
if generated.
Spreader
-to
prevent
kerf
from
closing
in
on
sawblade
and
possible
kickback;
-to
prevent
"wrong-way
feed".
"Wrong-way
feed"
is
feeding
the workpiece
-- when
sawblade
is in a rip
position
-- into
the outfeed
side of the cutting
tool
(sawblade,
dado,
molding
head,
etc.),
the
side
containing
the
antikickback/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).
Danger
label on
guard.
"Wrong-way
feed"
occurs
when
the teeth
themselves
cut,
or attempt
to cut,
a kerf
in the workpiece.
This
differs
from
a "kickback"
which
is generated
by the
sides (one
or both)
of the teeth,
because
of binding
between
the fence
(heel),
pinching
of the sides of the
sawblade
(failure
to use spreader),
and/or
inadequate
set of teeth
of sawblade.
-to
act as a partial
guard
regarding
accidental
contact
with
the sawblade
at the outfeed
side when
ripping,
and leading
edge when crosscutting.
a. The
blade
guard
is positioned
by
loosening
the
guard
clamp
screw
and
rotating
the guard
so that
the "nose"
just clears the workpiece
as shown.
b.The
antikickback
and spreader
assembly
must
be
adjusted
to
accommodate
the
thickness
of
the
board
being
ripped.
A wing

secures the assembly.

Loosen
the
wing
screw
and
with
the
tab
provided,
position
the
antikickback
and spreader
assembly
until
the
pawl
assumes
approximately
the
position
shown
above.
Tighten
the wing screw.
(Make
sure
by
trial
before
starting
the
cut
that
the
antikickback
pawls
will
stop
a kickback
once
it
has
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
to
direction
of
feed).
Readjust
Pawls if they do not stop the kickback
motion
by biting
into
the workpiece.
