When positioning the anti-kickback and spreader
assembly for bevel ripping, lower the assembly until
the Iocknut just clears the workpiece. If the pawls do
not catch, further adjustment is necessary.
Before repositioning the yoke to the crosscut posi-
tion, false the anti-kickback assembly to the upper
limit and secure.
The tips of the anti-kickback pawls should be
checked occasionally and kept sharp.
2. The Sawdust Chute
a. The sawdust chute (16, figure 34) is used to help
prope! sawdust from the cut and provide a hold-
down for boards during ripping.
b The sawdust chute is positioned by grasping the
upper tab et lower end of chute, loosening the knob
(17, figure 34) and raising or lowering it to just clear
the top surface of the board being ripl_ed_'T-_ght_'_n_
the knob secures the chute.
c. Before repositionlng the yoke to the crosscut posi-
tion, raise the chute to the upper limit and secure.
IMPORTANT: In ripping operations the work-
piece is always fed from the sawdust chute side,
never from the anti-kickback side of the guard.
(See figures 41 and 42.)
PRECISION INDEXING
Experienced operators of precision equipment, such as your
Craftsman Radial-Arm Saw, normally acquire the habit of
indexing the machine in one direction only, whenever a
new setting is made in preparation for a different operation.
For example: when moving the radial arm to a new
position, it is advisable to move it slightly past the desired
index position, then return it slowly and carefully to latch
and lock it. Figure 34 inset shows the radial arm being se-
curely indexed by "tapping" the arm latch lever with the
palm of the hand. Swivel indexing and bevel indexing can
be accomplished in a similar manner This indexing tech-
nique tends to neutralize any stresses imposed upon the saw
components, and contributes to the high degree of accuracy
the saw is capable of producing when operated expertly.
BASIC SAW OPERATIONS
REQUIREMENTS FOR CROSSCUT
(OPERATIONS 1 THROUGH 4)
1. Be sure you return the carriage to the full rearward posi-
tion at the conclusion of each cut. Never remove your
hand from the bevel index handle unless the carriage is
in this position. Allow the saw blade to come to a com-
plete stop before removing the workpiece from the saw
table.
2. Arbor nut must be tight and saw blade guard installed in
a horizontal position with anti-kickback device in full up
position.
3. Arm latch handle (knob) must be tight.
4. Work must be held firmly against table and fence. For
workpieces thicker than the fence is high, it is recom-
mended that a higher fence be cut (at least workpiece
thickness) and inserted for that operation being per-
formed. Always place the fence in the most forward
position (farthest from the column support) compatible
with the workpiece being processed and the operation
being performed. With the carriage fully retracted, the
blade should not contact the workpiece when placed
against the fence, within the stated capacities of your
saw.
5. Blade should be sharp and correctly set.
6. Hands must be kept well away from saw blade.
7. Yoke clamp handle must be in locked position.
8. Bevel index knob must be tight.
9. For operations No. 3 and No. 4, observe additional in
struetions under paragraph, "Operating Controls",
"Blade A_gle".

OPERATION NO. 1 -- CROSSCUT
Crosscutting is the process of sawing the workpiece by pull-
ing the saw blade through it and using the fence as a sup-
port for the edge of the workpiece. Never crosscut free-
hand.
WARNING: BEFORE CROSSCUTTING, MAKE
SURE THE ARM LATCH, BEVEL LOCK AND
YOKE CLAMP ARE ALL SECURED, NEVER USE
A LENGTH STOP OR A FIXED GUIDE ON THE
FREE END OR EDGE OF A WORKPIECE. (SEE
INSTRUCTION 15 UNDER "'SAFETY INBTRUC-
TIONS TO OPERATOR".) DO NOT CROSSCUT
WORKPIECES THAT PLACE YOUR HANDS
CLOSE TO THE PATH OF THE SAW BLADE.
WHEN MORE EXPERIENCE IS GAINED BY
USING THE SAW, IT WILL BE NOTICED, THAT
WHEN PULLING THE SAW TOWARD YOU DUR-
ING CROSSCUTTING, THE BLADE TENDS TO
FEED ITSELF THROUGH THE WORK DUE TO
THE ROTATION OF THE BLADE AND THE
DIRECTION OF THE FEED. THEREFORE, THE
OPERATOR SHOULD DEVELOP THE HABIT OF
HOLDING HIS RIGHT ARM STRAIGHT FROM
THE SHOULDER TO THE WRIST.
