OPERATIO
J
■ Avoid awkward operations and hand positions where
a sudden slip could cause serious injury from contact
with the blade. Never place hands in blade path.
■ Use extra supports (tables, saw horses, blocks, etc.)
when cutting large,
small,
or awkward workpieces.
■ Never use a person as a substitute for a table exten
sion or as additional support for a workpiece that is
longer
or wider than the basic saw
table.
■ When cutting irregularly shaped workpieces, plan your
work so it will not pinch the blade. For example, a
piece of molding must lie fiat on the saw table. Work
pieces must not twist, rock or slip while being cut.
When backing up the workpiece, the
blade
may bind in
the kerf (cut). This is
usually
caused by sawdust
clogging
the kerf or when the blade comes out of the guides. If this
happens:
■ Wait until
the
saw
has come to a full and complete
stop.
■ Place the switch
in
the
OFF
position then remove the
switch
key from the switch assembly. Store key in a
safe place.
■ Unplug the saw from the power source.
■ Wedge the kerf open with a flat screwdriver or wooden
wedge.
■ Open front cover and turn the upper wheel by hand
while backing up the workpiece.
relief
cuts
Relief cuts are made when an intricate curve (too small a
radius
for the blade) is to be cut.
Cut
through a scrap sec
tion of the workpiece to curve
in
pattern line then
carefully
back the
blade
out. Several relief cuts should be made for
intricate curves before following the pattern
line
as
sec
tions
are cutoff of curve
“relieving”
blade pressure.
SCROLL CUTTING
For general type scroll cutting, follow the pattern
fines
by
pushing and turning the workpiece at the same time. Do
not try to turn the workpiece while engaged in the blade
without pushing it, the workpiece
could
bind or
twist
the
blade.
REMOVING JAMMED MATERIAL
Never remove jammed cutoff
pieces until
the
blade
has
come to a
full
and complete stop.
■ Place
the switch in the
OFF
position, remove the
switch key
from
the switch assembly.
■ Unplug the saw from the power source before remov
ing jammed material.
AVOIDING INJURY
■ Make sure saw is
level
and does not rock. Saw
should
always
be on a firm, level surface with plenty of room
for handling
and properly
supporting the workpiece.
■ Bolt saw to the support surface to prevent slipping,
walking, or
sliding
during operations like
cutting long,
heavy boards.
■ Turn saw off, remove switch key, and
unplug
cord from
the power source before moving the saw.
■ Do
not
remove jammed
cutoff
pieces
until
blade has
come to a full and complete stop.
■
Choose
the right size and
style
blade for the material
and type of cut you plan to do.
■ Make sure that the blade teeth point down toward the
saw table, that the
blade guides,
thrust bearings, and
blade
tension are properly adjusted, that the blade
guide
knob is tight, and that no parts have excessive
play.
■ To avoid
accidental blade
contact,
minimize blade
breakage, and
provide maximum
blade support, al
ways adjust the blade
guide assembly
to just clear the
workpiece.
■ Use only recommended accessories.
■
With
the exception of the workpiece and
related
sup
port devises, clear everything off the saw table before
turning the saw on.
■
Properly
support round
materials
such as
dowel
rods
or
tubing
because they have a tendency to roll during
a cut
causing
the blade to “bite.” To avoid
this,
always
use a “V” block
or
clamp workpiece to a miter gauge.
■ Before removing loose pieces from the
saw table,
turn
saw
off
and wait for all moving parts to stop.
