Safety
This manual has safety information and instructions to help users eliminate or reduce
the risk of accidents and injuries, including:
1. Severe cuts, and loss of fingers or other
body parts due to contact with the blade.
2. Eye impact injuries, and blindness, from being hit by a thrown workpiece, workpiece
chips or pieces of blade.
3. Bodily impact injuries, broken bones, and internal organ damage from being hit by a
thrown workpiece
4. Shock or electrocution
5. Bums.
Major Hazards
Three major hazards are associated with using the radial arm saw for ripping. They
are outfeed zone hazard, kickback, and wrong way feed.
This section only briefly explains these haz- ards. Read the ripping and crosscutting safe- ty sections for more detailed explanations of
these and other hazards.
Outfeed Zone Hazard
DANGER
Safety Symbol and Signal Words
An exclamation mark inside a triangle is the safety alert symbol.
It is used to draw attention to safety informa- tion in the manual and on tile saw. It is
followed by a signal word, DANGER,
WARNING, or CAUTION, which tells the level of risk:
,_ DANGER: means if the safety infor-
mation is not followed someone will be seri- ously injured or killed.
4_lL WARNING: means if the safety infor-
mation is not followed someone could be seriously injured or killed.
4_lb CAIYFION: means if the safety infor-
mation is not followed someone might be
injured.
Read and follow all safety information and instructions.
If you reach around the blade to the outfeed side when ripping, and try to hold down or pull the workpiece through to complete a
cut, the rotational force of the blade will pull your hand back into the blade.
Fingers will be cut off. Read and follow the information and
instructions under ripping safety.
Safety
Kickback Hazard
Kickback is the uncontrolled propelling of the workpiece back toward the user during
ripping. The cause of kickback is the binding or
pinching of the blade in the workpiece.
Several conditions can cause the blade to bind or pinch.
When a workpiece kicks back, it could hit hard enough to cause internal organ injury,
broken bones, or death.
Read and tbllow the information and instructions under ripping safety.
WARNING
O
,0._.._
Wrong Way Feed Hazard
Wrong wa xfeed is ripping by feeding the workpiece into the ouffced side of tile blade.
The rotational force of the blade can grab
and pull the workpiece.
Before you can let go or pull back, the force could pull your hand along with the work-
piece into lhe blade. Fingers or hand could
be Ctlt Off'.
The propelled workpiece could hit a by- stander, causing severe impact injury or
death.
Read and tbllow the information and instructions under ripping safety.
WARNING
Wrong Way Feed
Guard Function and Features
"I]_eguard is a very important safety feature, designed to reduce the risk of injury associ- ated with blade contact. Install the guard
correctly. Follow the specific instructions in the ripping and crosscutting sections to set and use the guard correctly for each
type of cut.
Safety
Guard Features Include:
1. A non-moveable metal upper portion, (Upper Guard) which is fastened to the motor by the guard clamp screw, and which fully covers the upper half of the blade.
2. A moveable clear plastic portion,
(Plastic Lower Guard) which partially cov- ers the lower half of the blade. It protects
against contact with the side of the blade
during crosscutting when blade is in its rear- most position and the guard is resting on the
table, so the leading and trailing teeth of the blade are not exposed. It also protects against contact with the outfeed side of the
blade during ripping, and acts as a barrier to prevent wrong way Iced.
3. A squeeze trigger in the saw handle to fully raise the clear plastic guard at the start
of a crosscut. Note: This is necessary
because the guard will not automatically raise to clear the fence.
4. A hold down to be lowered to just clear the top of the workpiece for ripping. It acts
as a barrier to the infeed side of the blade, keeps the workpiece from fluttering, and
acts as a sawdust deflector. It is locked!unlocked by the hold down knob.

5. A riving knife to be lowered to the table
for ripping. It keeps the workpiece kerr open, thereby reducing blade pinching and
the risk of kickback. It also acts as a barrier to the hazardous outfeed side and prevents
wrong way feed. It is locked/unlocked by

the riving knife/pawls knob. When lowered for crosscutting, it acts as a barrier to the
leading edge of the blade.
6. Set of pawls to be lowered to the work-
piece surface for ripping. They allow the
workpiece to pass freely from infeed to out-
feed side, but help stop the kickback motion from outfecd to infeed side by grabbing into the workpiece surface. Pawls must be re-set
each time a different thickness workpiece is cut.
7. A guard tab to manually raise the plastic guard at the start of ripping unusual work-
pieces whose size/shape do not cause the guard to raise automatically.
Guard Tab
Hazards Associated with Clear
Portion of Guard
The following safety information applies to all blades and accessories.
_WARNING
Clear plastic portion of guard will not provide any protection during
crosscutting if blade is pulled over your hand, or your hand enters
blade path from front or rear of blade. Fingers or hand can be cut or
cut off.
Clear plastic guard will increase risk of certain hazards:
* During rip and bevel cuts, narrow
cut-off pieces can be pinched
between guard and blade. Cut-off pieces can kickback.
_'k CAUTION
Clear plastic portion of guard can get caught or jam in fence or table kerfs. Read and follow the warning
on the guard:
_WARNING:
TO AVOID INJURY
SHUT OFF POWER
BEFORE CLEARING A
JAMMED LOWER GUARD
WARNING
Cut off pieces can jam between guard and blade. Turn saw off and
wait for blade to stop before freeing jammed guard or blade.
In bevel position blade teeth are
fully exposed. Fingers or hand can
be cut off.
Workpiece or cut-off pieces can
be violently thrown by blade. Wear safety goggles. Stand out of work- piece path.
Safety Instructions
Read and follow all safety instructions.
Personal Safety Instructions
1. Wear safety goggles labeled "ANSI Z87.1" on the package. It means the goggles
meet impact standards set by the American National Standards Institute. Regular eye- glasses are not safety goggles.
Safety
Safety Goggles
2. Wear close fitting clothes, short sleeved shirts, and non-slip shoes. Tie up long hair.
Do not wear gloves, ties, jewelry, loose
clothing, or long sleeves. These can get caught in the spinning blade and pull body parts into the blade.
3. Wear dust mask to keep from inhaling fine particles.
4. Wear ear protectors, plugs or muffs if you use saw daily.
5. Keep good footing and balance; do not over-reach.
Work Area Safety Instructions
1. Keep children, pets, and visitors out of
work area; they could be hit by a thrown workpiece, workpiece chips or pieces of
blade.
2. Turn saw off, remove yellow key, and unplug before leaving work area. Do not
leave until blade has stopped spinning.
Dust Mask
Ear Protectors
3. Make work area child-proof: remove yel- low key to prevent accidental start-up; store key out of sight and reach; lock work area.
4. Keep floors clean and free of sawdust, wax and other slippery materials.
5. Keep work area well lighted and unclut- tered.
6. Use saw only in dry area. Do not use in wet or damp areas.
Safety
Saw Safety Instructions
1. Use guard, pawls and riving knife accord-
ing to instructions. Keep them in working order.
2. Routinely check saw for broken or dam- aged parts. Repair or replace damaged parts before using saw. Check new or repaired
parts for alignment, binding, and correct
installation.
3. Unplug saw before doing maintenance, making adjustments, correcting alignment,
or changing blades.
4. Do not force saw. Use saw, blades and accessories only as intended.
5. Have yellow key out and saw switched off
before plugging in power cord.
6. Before turning on saw, clear table of all
objects except workpiece to be cut and nec- essary fixtures, clamps, or feather-boards.
7. If blade jams, turn saw off immediately, remove yellow key, the free blade. Do not try to free blade with saw on.
8. Turn saw off if it vibrates too much or makes an odd sound. Correct any problem
before restarting saw.
9. Do not layout, assemble, or setup work with saw on, or while blade is spinning.
10. Keep saw table clean.
11. Store items away from saw. Do not
climb on saw or stand on saw table to reach items because saw can tip over.
Workpiece Safety Instructions
1. Cut only wood, woodlike or plastic mate-
rials. Do not cut metal.
2. Cut only one workpiece at a time. Stacking or placing workpieces edge to edge
can cause user to lose control of workpiece.
3. Rip only workpieces longer than the diameter of the blade. Do not rip workpieces
that are shorter than the diameter of the blade being used.
4. Workpieces that extend beyond the saw table can shift, twist, rise up from the table,
or fall as they are cut or afterwards. Support workpiece with table extensions the same
height as the saw table.
Safety
5. To prevent tipping, support outer ends of extensions with sturdy legs or an outrigger.
6. Do not use another person to help support workpieces or to aid by pushing or pulling
on workpieces, because these actions can cause kickback. Use table extensions.
7. Use clamps or vice to hold workpiece. It's safer than using your hands.
Blade Safety Instructions
I. Use only blades marked for at least 3450
rpm.
2. Use only 10" or smaller diameter blades.
3. Use blades for their recommended cutting procedures.
4. Keep blade sharp and clean.
5. Do not overtighten blade nut because blade collar could warp.
6. Do not turn saw on and off in rapid sequence because blade can loosen.
7. Blade should stop within 15 seconds after saw is switched off. If blade takes longer, the saw needs repair. Contact Sears Service
Center.

With the aml at an "'unindexed" position and the miter lock applied, the locking action
should feel tight and secure.
Considerable effort should be required to move the arm back towards 0 °. Its is always possible to force the arm because of the
leverage advantage the long arm provides. However, the arm should resist moving
when a reasonable amount of force is
applied. To check tbUow these steps:
1. Pull miter/arm lock forward to unlock and rotate arm to approximately 30° left or right.
2. Lock miter/ann lock by pushing handle toward rear of saw.
3. Apply pressure as shown above.

Adjustments
Arm to Column Adjustment
If you can move the end of the radial arm up and down when the ann is unlocked, adjust
as directed below:
a. Remove two (2) screws from rear cover plate. Tighten evmfly top two 3/8-16 bolts
until arm moves firmly. There should be no
vertical or horizontal movement in the arm when miter/arm lock is locked and
unlocked. b. Bottom two nuts should be snugged
evenly, but not nearly as tight as top two
bolts.
c. Re-lnstall Rear Cover Plate.
Adjusting Column Tube in Column
Support
This adjustment will remove any looseness between the column tube and column support while serving two purposes:
To insure accurate cuts; and
To allow the column tube to raise and lower
smoothly. Note: The f!)llowing adjustment is very criti-
cal All _ture alignment procedures rely on this adjustment being perforrned correctly.
All looseness must be removed.
"INs section is set up in two sections:
Alignment checks and adjustments.
It is very important that the column tube and
the inside of the column support are coated with a film of uncontaminated lubricant.
Alignment Checks
Two checks are required, these are adjusted at
the factory, but may have shifted out of align- ment during shipment.
1. Index and lock arm at 0 ° Miter.
2. Vertical Alignment Check:
The column support needs to be compres_d
using the black and silver screws so that it properly controls the movements of the col-
umn tube. Precise alignment is done only by the bright plated 5/16-18 screws.
With your lelt elbow resting on the base under the front of radial arm, push up slightly on the
ann. [x_ok ILr a noticeable movement between the colunm |ube and the column support.
318-16 Bolts
3/8-16 Nuts

3. Rotational Alignment Check: While holding the ann with one hand, hold fingers of other hand as shown, between
column tube and coluiml support. Apply gentle side-to-side pressure at end of arm. Any side-to-side or rotational movement
can be felt with finger at arrow location.
Alignment Adjustments
1. Loosen (2) 1/4 - 20 Gib .socket cap screws
on the left side at the rear of the column sup- port slightly (1/2 turn). Note: If Vertical Alignment was OK and
adjustment is not needed, proceed to step 6.
2. Vertical Adjustment:
Using the closed end of a box wrench, tighten all of the 5/16-18 black screw heads on the
colunm support casting 1/16th to 1/8th of a
turn. Tighten the (2) 5/16-18 silver screw heads slightly more than the black ones to
achieve a close fit to the colunm tube. (A 1/4" drive ratchet with a six point rocket may be
needed to get enough torque on bolts.)
3. Elevate and then lower the Arm using the elevation crank.
4. If the column tube binds and elevation is difficult, go back to step 2 and loosen the
screws until you achieve smooth but firm ele- vation, recheck step 3.
5. Redo "Vertical Alignment Check". a. If vertical mi_lignment still exists,
repeat steps 2 through 4. b. K vertical misalignment no longer exists, and you have achieved smooth but firm
elevation, proceed to step 6.
6. Rotational Adjustment: Tighten the (2) 1/4-20 Gib socket cap screws
until no noticable rotational play exists as in "Rotational Alignment Check".
7. Redo "Rotational Alignment Check" a. If rotational misalignment still exists, repeat step 6.
b. If rotational misalignment no longer exists, and you have achieved smooth but
firm elevation, this alignment procedure is complete.

Adjusting Carriage Bearings
If the carriage bearings are loose it not only allows the saw blade to move up, down, and sideways but also results in inaccurate cuts.
Before following these steps make sure the tracks (steel rods) and carriage bearings have
been cleaned by wiping them with a clean cloth.
When properly adjusted, the top and bottom face of all four beating grooves should be in
contact with the arm tracks for their entire length and carriage should roll smoothly
with some resistance.
To test for looseness between bearings and tracks on radial arm, perform the following
steps.
1. Remove left-hand carriage cover. (2
screws)
2. Push tile carriage to its full rearward posi- tion.
3. Grasp front carriage bearing as shown and hold as tight as possible. At the same time pull carriage forward. If you can stop the
bearing from turning, it requires adjusting.
4. Check rear bearing in the same manner.
5. Adjust as follows:
a. Use two 1/2" wrenches to loosen nut
just enough to permit the eccentric screw
to turn.
b. Rotate the eccentric screw a partial turn (left or right) as required to take up loose-
ness.
c. Hold the head of eccentric screw in the position established in the preceding step
and tighten nut on underside of carriage. Correct adjustment exists when you can-
not keep the bearings from turning. However. excessive beating pressure will
cause difficult operation and rapid wear.
