RULES FOR SAFE OPERATION (Continued)
USE THE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition. Use
only a cord heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating. A wire gage size (A.W.G.) of at least
14 is recommended for an extension cord 25 feet
or less in length. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier
the cord,
AVOID ACCIDENTAL STARTING. Be sure switch
is off when plugging in the tool.
REMOVE WRENCHES AND ADJUSTING KEYS.
Get in the habit of checking - before turning on the
tool - that hex keys and adjusting wrenches are
removed from tool.
CHECK DAMAGED PARTS. Before using the tool
again, check any damaged parts, including guards,
for proper operation and performance. Check
alignment of moving parts, binding of moving parts,
breakage of parts, saw stability, mounting, and any
other conditions that may affect its operation. A
damaged part must be properly repaired or re
placed by a qualified service technician at a Sears
repair center to avoid risk of personal injury.
USE ONLY CORRECT BLADES. Use the right
blade style for the material and the type of cut.
Use only blades marked for at least 5,000 rpm and
10 in. or smaller, with a 5/8 in. arbor hole.
KEEP GUARDS IN PLACE and in good working
order. This includes the blade guard, the riving
knife, and the anti-kickback pawls.
CHECK DIRECTION OF FEED. When ripping,
feed work into a blade or cutter against the direc
tion of rotation of the blade or cutter,
NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN THE POWER OFF. Do not leave the tool
until it comes to a complete stop.
USE RECOMMENDED ACCESSORIES. Using
improper accessories may risk injury. Consult the
Accessories section for recommended accesso
ries,
USE ONLY SEARS REPLACEMENT PARTS. All
repairs, whether electrical or mechanical, should
be made by a qualified service technician at a
Sears repair center.
DISCONNECT ALL TOOLS. When not in use,
before servicing, or when changing attachments,
blades, bits, cutters, etc,, all tools should be
disconnected from the power supply.
DO NOT FORCE THE TOOL. It will do the job
better and more safely at the rate for which it was
designed.

AVOID AWKWARD OPERATIONS AND HAND
POSITIONS where a sudden slip could cause your
hand to move into the blade. ALWAYS make sure
you have good balance.
CRflFTSMfir RADIAL SAW 315.273731
RULES FOR SAFE OPERATION (Continued)
GUARD AGAINST KICKBACK. Kickback can
occur when the blade stalls, driving the work piece
back toward the operator. It can cause your hand
to contact the blade, resulting in serious personal
injury. Stay out of the blade path and turn switch
off immediately if blade binds or stalls.
DO NOT USE A PERSON AS A SUBSTITUTE
FOR A TABLE if additional support is needed. Use
a support the same height as the table.
USE A SUPPORT FOR THE SIDES AND BACK
OF THE SAW TABLE when sawing wide or long
workpieces to minimize the risk of blade pinching
and kickback. Use a sturdy “outrigger” support to
prevent tipping if a table extension more than 24
inches long is attached to the saw.
CUT ONLY WOOD, PLASTIC OR WOOD-LIKE
MATERIALS. Do not cut metal.
BEFORE MAKING A CUT, be sure all adjustments
are secure.
NEVER cut more than one piece at a time, DO
NOT STACK more than one workpiece on the saw
table at a time.
DO NOT REMOVE THE SAW'S BLADE GUARD.
Never operate the saw with the blade guard
removed. Make sure all guards are operating
properly before each use.
NEVER PERFORM ANY OPERATION FREE
HAND. Always place the workpiece to be cut on
the saw table and position it firmly against the
fence as a backstop.
USE THE RIP FENCE. Always use a fence or
straight edge guide when ripping.
BE SURE THE BLADE PATH IS FREE OF
NAILS. Inspect for and remove all nails from
lumber before cutting.
BE SURE THE BLADE CLEARS THE WORK
PIECE. Never start the saw with the blade touching
the stock.
KEEP HANDS AWAY FROM CUTTING AREA.
Do not reach underneath work or in blade cutting
path with your hands and fingers for any reason.
Always turn the power off when cut is complete.
USE A PUSHBLOCK OR PUSHSTICK in rip mode
for workpieces so small that your fingers go under
the blade guard. NEVER TOUCH BLADE or other
moving parts during use, for any reason.
■ ALLOW THE MOTOR TO COME UP TO FULL
SPEED before starting a cut to avoid blade binding
or stalling,
■ ALWAYS PUSH THE WORKPIECE when ripping;
never pull it toward the saw,
■ DO NOT FEED THE MATERIAL TOO QUICKLY.
Do not force the workpiece against the blade.
■ ALWAYS TURN OFF SAW before disconnecting
it, to avoid accidental starting when reconnecting
to the power supply. NEVER leave the saw
unattended while connected to a power source.
■ BEFORE CHANGING THE SETUP, REMOVING
COVERS, GUARDS, OR BLADE; unplug the saw
and remove the switch key.
■ KEEP TOOL DRY, CLEAN, AND FREE FROM
OIL AND GREASE. Always use a clean cloth
when cleaning. Never use brake fluids, gasoline,
petroleum-based products, or any solvents to
clean tool.
■ KEEP BLADES CLEAN, SHARP AND WITH
SUFFICIENT SET. Sharp blades minimize stalling
and kickback. Keep blades free of rust, grease,
and pitch.
WARNING: Blade coasts after being turned off.
■ USE ONLY OUTDOOR EXTENSION CORDS.
Use only extension cords with the marking “Ac
ceptable for use with outdoor appliances; store
indoors while not in use.” Use extension cords with
an electrical rating not less than the saw’s rating.
Always disconnect the extension cord from the
outlet before disconnecting the product from the
extension cord.
■ INSPECT TOOL CORDS AND EXTENSION
CORDS PERIODICALLY and, if damaged, have
repaired by a qualified service technician at a
Sears repair center. Stay constantly aware of cord
location and keep it well away from the moving
blade.
■ DO NOT ABUSE CORD. Never yank the cord to
disconnect it from receptacle. Keep the cord from
heat, oil, and sharp edges.
■ SAVE THESE INSTRUCTIONS. Refer to them
frequently and use to instruct other users. If you
loan someone this tool, loan them these instruc
tions also.
SAVE THESE INSTRUCTIONS
ERflPTSMHI* RADIAL SAW 315.273731
ADDITIONAL SAFETY RULES FOR RADIAL SAWS
SECURE THE SAW. Firmly bolt the saw to the leg
stand to keep the saw from tipping, walking, or
sliding,
DO NOT SET UP WORK WITH THE BLADE
SPINNING. Keep the saw power off until you are
ready to use it.
RIP ONLY WORKPIECES LONGER THAN THE
BLADE’S DIAMETER. Never rip a piece of wood
that is shorter than the diameter of the blade.
NEVER LOWER AN UNLOCKED REVOLVING
CUTTING TOOL. Always lock the carriage lock
knob before lowering the blade.
SHUT OFF THE POWER TO FREE A JAMMED
GUARD. Press the switch off before putting your
hands near the blade. Wait for the blade to stop,
then free the guard.
LOCK THE SAW BEFORE MOVING IT. Secure
the radial arm with the arm lock knob. Secure the
carriage with the carriage lock knob.
POSITION THE WORKPIECE WITH THE FIN
ISHED SIDE DOWN. If the anti-kickback pawls
catch the wood to stop kickback, they could mar
the top surface or cause splintering.
POSITION THE WORKPIECE SO NO ONE MUST
STAND IN LINE WITH THE BLADE. If kickback or
climb occurs, a helper, operator, or observer in the
sawblade path could be seriously injured.
POSITION THE CUT SO THE WASTE PART
FALLS OFF. Never use a length stop on the free
end of the workpiece. Never apply force to the free
end or hold it while the sawblade is rotating.
L WARNING: In a rip cut, holding the cut-off edge
behind the blade can cause the cut edges to
pinch, risking kickback. It could cause the blade
to climb over the front edge of the wood and
contact your hand.
BEFORE CUTTING, position and tighten the blade
guard and anti-kickback pawls. Test the pawls to
make sure they would stop kickback if it started.
Keep the points sharp.
KEEP THE SAW BLADE PATH CLEAR. Position
the saw to allow enough room on all sides so
neither the operator nor a visitor stands in line with
the sawblade.
AVOID HEELING by adjusting the saw blade so it
exactly parallels the fence during ripping opera
tions.
AVOID GRABBING in rip mode by keeping the
saw blade correctly adjusted and by feeding the
work from the infeed side (opposite the anti
kickback pawls).
AVOID PINCHING by using a riving knife and
sharp saw blade. Keep the work positioned firmly
against the fence.
USE IN-RIP WHENEVER POSSIBLE by position
ing the work so the blade is between (inside) the
column and the motor.
NEVER ADJUST GUARD, PAWLS, OR BLADE
WITHOUT DISCONNECTING THE POWER.
Always turn off the switch and unplug the cord
before freeing a jammed blade, tightening a loose
blade, or repositioning the guard or pawls.
CAUTION: Do not turn the motor switch on and
off rapidly. This can loosen the sawblade.
NEVER CUT MORE THAN ONE PIECE OF
WOOD AT A TIME. The feed will be uneven and
could cause the blade to pick up one or more
pieces and cause serious injury,
TURN OFF SAW IF A STRANGE NOISE OR
HEAVY VIBRATION OCCURS. Immediately turn
off the saw, locate the source, and correct the
problem before using the saw further.
BEFORE STARTING EACH CUT, check that no
play exists in the carriage. Be sure the arm, yoke
and bevel locks and clamps are tight. Verify the
blade, all handles, blade washers, and blade nuts
are secure,
BEFORE MAKING A CUT, test the upper and
lower blade guards for free movement up and
down. Position the nose of the guard to just clear
the workpiece.
AVOID KICKBACK AND POSSIBLE INJURY by
preventing heeling, grabbing, and pinching.
POSITION THE CUT SO THE BLADE WILL NOT
EXTEND BEYOND THE EDGE OF THE TABLE.
KEEP THE GUARDS IN PLACE AND THE WORK
SURFACE CLEAR DURING A CUT. Small objects
or wood slivers can ricochet from the blade into the
fence and back toward the operator. If the blade
loosens slivers, remove them with a stick, not your
hand,
IN A RIP CUT, DO NOT LET GO OF THE WORK
PIECE UNTIL THE CUT IS COMPLETE. When the
workpiece is fed into the blade, push the workpiece
all the way past the blade.
CRflFTIMOr RADIAL SAW 315.273731
ELECTRICAL
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug. When using a power tool at a consider
able distance from the power source, use an exten
sion cord heavy enough to carry the current that the
tool will draw. An undersized extension cord will
cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire
size required in an extension cord. Only round jack
eted cords listed by Underwriter's Laboratories (UL)
should be used.
Length of Extension Cord Wire Size (A.W.G.)
Up to 25 feet 14
26-100 feet 12
When working with the tool outdoors, use an exten
sion cord that is designed for outside use. This is
indicated by the letters WA on the cord's jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
CAUTION: Keep the cord away from the cutting
area and position the cord so that it will not be
caught on lumber, tools, or other objects during
cutting operations.
ELECTRICAL CONNECTION
Your Sears Craftsman Radial Arm Saw is powered by
a precision built electric motor. It should be connected
to a power supply that is 120 volts, 60 Hz, AC only
(normal household current). It should be connected
to a 240 volt power supply only if it has been reset
according to the instructions in this manual. The
motor has been set at the factory for 120 volts; if it is
reconnected to operate at 240 volts, the main power
cord plug and any receptacle must be replaced with
devices rated for 240 volts. This tool will not operate
on direct current (DC), A substantial voltage drop will
cause a loss of power and the motor will overheat. If
the saw does not operate when plugged into an outlet,
double check the power supply.
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current
to reduce the risk of electric shock. This tool is
equipped with an electric cord having an equipment
grounding conductor and a grounding plug. The plug
must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided. If it will not fit the
outlet, have the proper outlet installed by a qualified
electrician. Improper connection of the equipment
grounding conductor can result in a risk of electric
shock. The conductor with insulation having an outer
surface that is green with or without yellow stripes is
the equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary,
do not connect the equipment-grounding conductor to
a live terminal.
Check with a qualified electrician or service personnel
if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is
properly grounded.
Repair or replace a damaged or worn cord immedi
ately.
This tool is intended for use on a circuit that has an
outlet like the one shown in Figure 1. It also has a
grounding pin like the one shown.
SPEED AND WIRING
The no-load speed of your saw is approximately 3,600
rpm. This speed is not constant. For voltage, the
wiring in a shop is as important as the motor’s horse
power rating, A line intended only for lights cannot
properly carry a power tool motor. Wire that is heavy
enough for a short distance will be too light for a
greater distance. A line that can support one power
tool may not be able to support two or three tools.

FEATURES
KNOW YOUR RADIAL SAW
See Figure 8A.
OVERVIEW - The main operating components include
the column, the arm, and the yoke assembly (yoke,
motor, and blade), and their operation is summarized
in the paragraph below. Safety features and control
functions are given also. Spending a few minutes
reviewing the illustrations and features list below and
on the following pages to locate these items will make
assembly easier,
METHOD OF OPERATION: The column at the back
of the saw supports the radial arm. The arm can be
raised or lowered to change the blade height or
swiveled left and right for a miter cut. A yoke fits into
a carriage on the arm, which can travel back and
forward. The yoke supports the yoke assembly
(motor, blade, and blade guard) and can be pivoted
so the blade faces right, front, or left. The motor can
be rotated to change the blade angle.
Control functions include 1) column height (elevating
handwheel), 2) arm angle (arm lock knob), 3) yoke
movement on arm (*carriage lock knob) 4) yoke
rotation (*yoke pivot latch and *yoke lock handle), and
5) blade bevel (*bevel index lever and *bevel lock
knob).
Safety features include the control cut device, the
removable switch key, and the blade guard assembly.
Never operate the saw without ensuring these safety
features are in place and functioning correctly.
On a radial saw, “cross cut” means a cut parallel to
the arm, and a “rip cut” is perpendicular to the arm.
There are several ways to make cuts, depending on
the size and material of the workpiece and the end
result desired.
Before attempting to use your saw, familiarize yourself
with all operating features and safety requirements of
your Sears Craftsman Radial Arm Saw.

ASSEMBLY
Assembly is best done in the area where the saw will
be used. When you remove the saw and hardware
from the packing materials, carefully check the items
with the Loose Parts list. If you are unsure about the
description of any part, refer to their illustrations. For
your convenience, all fasteners have been drawn
actual size. If any parts are missing, delay assembling
until you have obtained the missing part(s).
Your radial arm saw is capable of a wide variety of
operations, and thus requires a number of initial setup
adjustments. However, once the saw is set up, you
can check your saw in about ten minutes and correct
any misalignment with the procedures in the Adjust
ment section.
CAUTION: Perform all the procedures in both
the Assemb/y and Adjustments sections before
using the saw. Run a check on your saw
frequently, referring to the Adjustments section.
Failure to perform the adjustments in the initial
