2.
IMPROPER DEPTH OF CUT SETTING ON SAW
Using
the
saw
with an
excessive depth cut setting
increases
loading on
the unit and susceptibility
to twisting
of
the blade
in
the kerf. lt
also
increases
the surface area of
the
blade
avail-
able
for pinching under conditions
of kerf close down.
3.
B|-ADE TWIST|NG (M|SALIGNMENT
tN CUT)
A.
Pushing harder to
cut through
a
knot, 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 white 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
B.
Green lumber
(materialfreshly
cut or not kiln dried)
C. Pressure treated lumber
(material treated
with preserva-
tives or anti-rot chemicals)
5.
USE OF DULL OR DIRTY BI.ADES
Dull
or
dirÿ
blades cause increased loading
of the
saw, To
compensate, an
operator will usually push
harder which
fur-
ther loads the
unit and promotes twisting of
the
blade in the
kerf. Worn blades may also have reduced body
clearance
which increases the chance of
binding and
increased loading.
6.
LIFTING THE SAW WHEN MAKING BEVEL CUTS
Bevel_
cuts require special operator attention
to proper
cutting
techniques -
especially guidance of
the saw. Both blade anglé
to the shoe and greater
blade surface
in
the
material
increale
the chance for
binding and
misalignment (twist) to
occur.
7.
RESTARTING
A
CUT WITH THE
BLADE TEETH JAMMED."
AGAINSTTHE
MATERIAL
I
The saw should be brought up to
full
operating speed
beforèÿ
starting a cut
or restarting a cut after the unit has
been
stopped
with
the blade
in the kerf.
Failure to do so can
cause
stalling and kickback.
Any
other conditions which could result in pinching, binding, twisÈ
ing, or misalignment of the blade could cause kickback. Èefer to
the
sections
on 'Adjustments And
SetUp" and
"Operation', for
procedures and techniques that
will
minimize the occurrence of
kickback.
Blades
A dull
blade will
cause slow, inefficient cutting overload on the
saw
motor, excessive splintering
and could
increase the
possibili-
ÿ
of kickback. lt is a good practice
to
keep extra blades'on
hand
so that sharp blades are available while
the dull ones are
being
sharpened
(See
"SAWS-SHARPEN|NG" in
the
ye[ow
pages).
tn
fact, many lower priced
blades can be
replaced
with
new ônes
at
very
little cost over the sharpening price.
Hardened gum on
the
blade will
slow down the cutting. This gum
can best be removed with kerosene, turpentine or oven cleanôr.
DeWalt
manufactures
a complete line of saw blades and the
fol-
lowing
ÿpes
of blades are available from your service center.
VISUALLY EXAMINE CARBIDE BLADES BEFORE
USE.
REPLACE IF DAMAGED.
