tion is not followed someone may be injured.
Read and follow all safety information
and instructions.
Major Hazards
Three major hazards are associated with
usingthe radial arm saw for ripping. They
are outfeed zone hazard, kickback and
wrong way feed.
This section only briefly explains these hazards. Read the ripping and crosscutting
safety sections for more detailed explanations of these and other hazards.
Outfeed Zone Hazard
If you reach around the blade to the outfeed
side when ripping, and try to hold down or
pull the workpiece through tocomplete 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
4
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 follow the information and
instructions under ripping safety.
Wrong Way Feed Hazard
Wrong way feed is ripping by feeding the
workpiece into the outfeed side of the blade.
The rotational force of the blade can grab
and pull the workpiece.
Before you can let go or pull back, the force
couldpull your hand along with the workpiece into the blade. Fingers or hand could
be cut off.
The propelled workpiece could hit a
bystander, causing severe impact injury or
death.
Read and follow the information and
instructions under ripping safety.

Guard Function and Features
The guard is a very importantsafety feature,
designed to reduce the risk of injury associated 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.
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
fullycovers the upper half of the blade.
2. A moveable clear plastic portion, (Plastic Lower Guard) which partially covers the
lower half of the blade. It protectsagainst
contact with the side of the blade during
crosscutting when blade is in its rearmost
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,andacts as a barrier to
prevent wrong way feed.
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
abarriertotheinfeedsideoftheblade,
keeps the workpiece fromfluttering,andacts
as a sawdust deflector. It is locked/unlocked
by the hold down knob.
5. A riving knife tobeloweredtothetable
forripping. It keeps the workpiecekerf 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 tobeloweredtotheworkpiece surface for ripping. They allow the
workpiece to pass freely from infeed to outfeed side, but help stop the kickback motion
fromoutfeedtoinfeedsidebygrabbinginto
the workpiece surface. Pawls must be reset
each time a different thickness workpiece is
cut.
7. A guard tab to manually raise the plastic
guard at the start of ripping unusual workpieces whose size/shape do not cause the
guard to raise automatically.

Safety
Hazards Associated with Clear Portion of Guard
The following safety information applies to all
blades and accessories.
WARNING
Clear plastic portion of guard w ill 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.
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 P OWER
BEFORE CLEARING A
JAMMED LOWER GUARD
WARNING
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.
• In bevel position blade teeth are fully
exposed. Fingers or ha nd can be cut
off.
• Cut-off pieces can jam between
guard and blade. Turn saw off and wait
for blade to stop before freeing
jammed guard or blade.
• Workpiece or cut-off pieces can be
violently thrown by blade. Wear safety
goggles. Stand out of workpiece path.

Personal Safety Instructions
WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known (to the State of California)
to cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-bases paints,
• Crystalline silica from bricks and
cement and other masonry products, and
• Arsenic a nd chromium from chemically-treated lumber.
Your risk from these exposures varies,
depending on how often you do this
type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and work with approved
safety equipment, such as those dust
masks that are specially designed to
filter out microscopic par ticles.
1. Wear safetygoggles labeled ANSI Z87.1
(or in Canada CSA Z94.3-99) on the package. It means the goggles meet impact standardsset by the American National
Standards Institute. Regular eyeglasses are
not safety goggles.
2. Wear close fitting clothes, short sleeved
shirts, and non-slip shoes. Tie up long h air.
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.

Introduction
In order to get the most enjoyment out of your radial saw it is important that the machine be properly assembled, adjusted, and aligned. This procedure, although not difficult, takes time; perhaps
eighthours or longer for the inexperienced user. However, after this initial set-up a weekly tune-up
can be completed in approximately ten minutes by checking the alignment and only adjusting those
settings which are incorrect.

as directed below:
a. Remove two (2) screws from rear cover
plate. Tighten evenly top two 3/8-16 bolts
until the play is removed and the arm will still
move side to side freely .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
ev en ly, but not nearly as tight as top two bolts.
c. Re-install 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 following adjustment is
very critical
.
Allfuture alignmentprocedures rely on t his adjustment
being per formed correctly. All looseness must be
removed.
This section is set up in two sections:
Alignment checks and adjustments. It is very
important that the column tube and the
inside of the columnsuppor t are coated with
a film of uncontaminated lubricant.
Alignment Checks
Twochecks are required, theseare adjusted
at the factory, but may have shifted during
shipment.
1. Index and lock arm at 0° Miter.
2.
Vertical Alignment Check:
The two piece column support needs to be
compressed by tightening the black and silver screws to properly control the movement
of the column tube. Precise alignment is
done only by tightening or loosening the silver 5/16-18 screws in combination with the
brass set screw. Push up slightly on the end
of the arm. Look for a noticeable movement
between the column tube and the column
support.

fingers of other hand as shown, between column tube and column 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
Note:
IfVer tical Alignment wasOK and adjustmentis
not
needed, proceed to step 6.
1. Loosen (2) 1/4 - 20 Gib socket cap
screws on the left side at the rear of the column support slightly (1/2 turn).
2.
Vertical Adjustment:
Using the closed end of a box wrench, tighten
all of the 5/16-18 black screw heads on the column 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 column tube (Fig. 2). (A 1/4"
drive ratchet with a six point socket may be
needed to get enough torque on bolts.) Loosen
nut on brass set screw . Tighten the brass set
screw firmly and retighten nut (Fig. 2).
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 elevation, recheck step 3.
5. Repeat "Vertical Alignment Check
".
a. If vertical misalignment still exists,
repeat steps 2 through 4.
b. If 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 noticeable rotational playexists.(Fig. 3).
7. Repeat "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 carriagebearingsare 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 bearing 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 the carriage to its full rearward position.
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 bearingin the same manner.
5. Adjust as follows:
a. Hold the eccentric screw in place with
a 9/16" wrench. Use a 1/2" wrench to
loosen the nut on the bottom just enough
to permit the e ccentric screw to turn.
b. Rotate the e ccentric screw a partial
turn (left or right) as required to take up
looseness.
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 cannot keep the bearings from turning. However, excessive bearing pressure will
cause difficult operation and rapid wear.
d. Install carriage cover.
