ELECTRICAL CONNECTiONS
NOTE: This.saw motor i s wired at the factory
for 120-volt, 60 cycle, AC service as shown
in figure 1 and described in paragraph 1,
below. Under normal home workshop use
with proper voltage to the motor, the saw
will operote with adequate efficiency. However, i f any of the following conditions exist,
it may b e necessary to reconnect the sow
for 240 volts AC as described in paragraph
2, below.
b.
Leave the BROWN lead (from overload protector)
disconnected and insulate it with tape to prevent
short circuiting inside motor terminal box.
c. Connect the GREEN, RED a n d BLUE leads together,
twist bare ends and install a wire nut.
d.
Push all leads carefully into motor terminal box and
install terminal box cover.
3. M o d i f y i n g the Power Cord.
a. Cut off the existing molded plug (for 120-volts).
1. Continuous heavy-duty use.
b. Attach an appropriate 240-volt plug.
2. Undersize wiring i n circuit from motor to
power source, or overloaded circuit.
Low voltage from power source to motor
(which may be due to overlooded power
source).
The power cord must also be changed from the 120-volt type
to the 240-volt type, when changing to 240-volt operation.
1. Connections For 120-Volts AC. (See figure 1.) When
replacing a motor or connecting the saw to 120-volts
for any reason, make sure the wires inside the motor
terminal box are connected as follows:
a. Connect the YELLOW, WHITE, BLACK and RED leads
from the motor terminal box to the WHlTE motor cord
CAUTION: Do notconnect the stcndard 120volt plug t o a 240-volt receptacle.
MOTOR SAFETY PROTECTION
The saw motor i s equipped with a manual-reset thermal
overload protector, designed t o open the power line circuit
when the motor temperature exceeds a safe value.
1. If the protector opens the line a n d stops the saw motor,
press the saw switch to the "OFF' position immediately
and allow the motor to cool.
2.
After cooling to a safe operating temperature, the overload protector can be closed manually by pushing in

button will not snap into place immediately, the motor
i s still too hot and must be allowed to cool for a while
longer. (An audible click will indicate protector is closed.)
3. As soori os the red button will snap into running position,
the saw moy be started and operated normally by pressing the saw switch to the "ON" position.
4. Frequent opening of fuses or circuit breakers may result
if motor i s overloaded, or i f the motor circuit i s fused
with a fuse other than those recommended. Do not use
a fuse of greater copocity without consulting the power
company.
5. Although the motor i s designed for operation on the
voltage and frequency specified on motor nameplate,
normal loads will be handled safely on voltages not
more than 10% above or below the narneplote voltage.
Heavy loads, however, require that voltage at motor
terminals be not less than the voltage specified on
nameplate.
6. Most motor troubles may be traced to loose or incorrect
connections, overloading, reduced input voltage (which
results when small size wires are used in the supply
circui:) or when the supply circuit i s extremely long.
Always check connections, load and supply circuit when
the motor fails to perform satisfactorily. Check wire
sizes and lengths with the table in the next poragraph.
WIRE SIZES
The following table lists recommended wire sizes for connecting the motor to the power source. These sizes should
be maintained for trouble-free operotion of the saw.

STEP ONE - INSTALLATION OF FRONT TABLE
1. Place the large front table board on toble supports so
that holes in board match holes in supports. (See figure 3.)
2. Place a l / d i n c h plain wosher and a l/4-2Ox l-inch
screw in eoch of the seven counterbored holes located
above the table supports. One screw i s threaded into
a "U"-clip nut mounted on the No. 2 support.
3. Attach lockwashers and nuts to the six screws in the
table supports. Do not tighten these screws at this time.
STEP TWO - CHECKING F O R LOOSENESS OF
COLUMN TUBE IN COLUMN SUPPORT
1. Tighten arm latch handle (22, figure 20.)
2. Grasp arm latch handle (22, figure 20) with one hand
and hold fingers of other hand at parting line between
column tube and column support. (See figure 4.) Apply
gentle side force to the radial arm in opposing directions.
Any looseness between column and column support (indicated by arrow in figure 4) can be felt with fingers.
3. If looseness can be felt, at point indicated b y the arrow
in figure 4, perform operations outlined in instructions
h a t follow:
N O T E Before attempting to adjust the column tube key, the function of this adjustment
should be understood. Figure 5 shows a sectional view through the column tube support
(looking downward) at this location. By loosening the left-hand set screw and tightening
the right-hand set screw the column tube key
will be forced tighter into the column tube
keyway. Conversely, loosening the righthand set screw and tightening the left-hand

and position the saw and square until the leg of the
square iust contacts a tooth of the saw blade. (Position
"A", figure 7.) Mark this tooth with crayon or chalk.
5. When the carriage
i s moved back and forth on the radial
arm, the saw tooth "A" should just touch the square at
a l l positions. If saw tooth "A" does not touch the square
a t all points, make the following adjustments:
a. If saw tooth ("A", figure 7) moves away from the
square when moving the blade from the rear toward
the front of the table, tap the right-hand front edge
of the table.

NOTE: Actual contact with table can b e determined by rotating saw blade and listening for
a light "pinging" sound as the carriage i s
lowered.
4. Move the blade to point B near the rear edge of table.
(See figure 10.) If saw blade starts t o ride on table as i t
i s moved rearward, loosen the nut near the rear of the
No. 2 table support a n d t a p the table downward until
the blade just contacts the table at this point. If table
i s too low a t the back, t a p it upward until a pinging
sound can b e heard os blade i s rotated. Recheck at both

ADJUSTMENT O F RIP SCALE INDICATORS
NOTE: The rip scales and pointers are intended to b e used for quick settings. For greater
accuracy, toke direct measurement between
blade a n d fence.
1. When the fence i s in its normal position (next to the
front table), index the yoke 9
0' from the cross-cut position so that the blade i s between the motor and the
fence. Lock the yoke.
2. Move the motor along the radial arm until the blade,
when spun by hond, just touches the front face of the
fence. (See figure 18.) The indicator on the right-hand
side of radial arm should now reod 0-inches on lower
portion of the "In-Rip" scale. If not, logsen the two
screws and shift the indicator to reod 0-inches.
NOTE: With the saw bldde and fence in the
position shown in figure 18, the lower portion
of the "in-Rip" scale i s used. I f the fence is
moved to the extreme rear position, the upper
portion of the scale i s u.sed.
3. The "Out-Rip" scale pointer, located on the left-hand
side of radial arm, i s adjusted in essentially the same
manner as the "in-Rip" scale pointer, except the blade
should b e positioned as shown in figure 17. With 12inches measured between the fence (when in full rear
position) and face of saw blade, the pointer should be
set to the 12" position. The upper portion of the "OutRip" scale i s used when the fence i s in the rear position.
(See figure 19.) The lower portion of the scale i s used
when the fence i s located in the usual position
a t the
rear edge of front table board.

SET-UP GUIDE
A combined number and color code system, designated as
a "SET-UP GUIDE", has been applied to the saw in order
to simplify the location of tontrols req uired for a particular
set-up operation. The "SET-UP GUIDE" i s both a convenience and safety measure, particularly for inexperienced
operators., The operator should become familiar with this
feature before operating the saw. A brief explanotion of
the "SET-UP GUIDE" is as follows: (See figure 21.)
1. Notice the radial arm trim strip, the forward end of
..
which contains six diagrams numbered "1" through
6". Each number i s in a colored circle, and a corresponding number in an identical colored circle will b e
a n the particular operating control member involved.
2. Locate each control and become familiar with its operation.
a. "DEPTH OF CUT". Diagram shows :he elevation
crank which is used to raise a n d lower the blade. The
numeral "1" in a light-blue circle is on the crank
handle.
Figure 21
b. "ANGLE OF CUT". Two controls 'are involved in re-.
leasing, securing and indexing the angle of the radial
arm. These are: arm latch handle and arm latch
lever. The handle is marked with a dot:-blue circle.
c. "CARRIAGE PIVOT".'TWO controls are used i n this
operation. They are: swivel latch knob and yoke
clamp handle, each marked with the numeral "3"
in a n orange circle.
d. "CARRIAGE LOCK". The carriage lock knob is
rotated clockwise to secure the carriage on radial
arm, a n d counterclockwise to release it. The numeral
"4" i n a green circle is a t the center of the knob.
e. "BLADE ANGLE". The two controls used in angular
positioning a n d indexin g of the motor to provide the
desired saw blade angle are: bevel lock knob and
latch p i n handle. The numeral "5" in a yellow circle
is attached to the bevel lock knob. The latch p i n
handle i s painted yellow.
f . "POWER SWITCH". This switch is located in the
upper left a r e a of the carriage a n d has the numeral
"6" in a r e d circle directly under it.
USE OF KEY AND SWITCH
NOTE: This savt cannot be operated without
the key, and likewise, the key cannot be removed trom the lock while the sow motor is
running. This feature was designed into your
saw for safety and protection.
1. Insert key in slot and turn it. (See figure 22.)
2. Press the right-hand side of toggle switch lever to turn
the saw ON. Press left-hand side of switch to turn
saw
OFF.
RAISING AND LOWERING THE RADIAL A R M
This i s accomplished by the elevation crank (8, figure 23).

LOCKING THE CARRIAGE TO THE RADIAL ARM
This is accomplished by the carriage lock knob (3, fig"rb .;
23). Turn the knob clockwise to lock; counterclockwisq! tb'

I -&
ANGULAR MOVEMENT A N D LOCKING
OF RADIAL ARM
These movements are controlled by the arm latch lever
(1, figure 23) and the arm latch handle (12). The radial
arm can be rotated 360° and locked in any position. The
arm i s unlocked from any position b y a slight counterclockwise rotation of the arm latch handle (12) and is locked
in any position b y rotating the arm latch handle clockwise
until tight. The radial arm has positive stops at O0 and 45O
left and right, and is released from these index positions
by unlocking the arm latch handle (12) and pulling out
the arm latch lever (1).
For most positive and accurate settings at the index positions, the following i s recommended:
1. If the radial arm is already indexed, rotate the arm
latch handle (12, figure 23) 1/4 turn counterclockwise from the locked position, pull out the arm latch
lever (1) and move the radial arm off the index position.
Release the arm latch lever (1).
2. Move the radial arm into the index position (do not
bump or jar it) and push on the handle (12) or arm
latch lever (1) solidly with the palm of the hand. (See
figure 24). This i s very important as it insures proper
seating of the arm lock pin in the arm latch, thus always
returning the arm to the correct cross-cut (0°) position.
3. Lock the radial arm by rotating the arm latch handle
(12, figure 23) clockwise until tight.
CAUTION: When moving the radial arm i n any
direction beyond 4S0 left or right, always pull
out the arm latch lever (at end of radial arm)
to prevent damaging the arm lock pin. If damage occurs, the radial arm will not index
properly a t '0 and 4S0 positions (left to right).
MOVEMENT AND POSITION OF MOTOR IN YOKE
These movements are controlled by th'e latch'pin handle
(6, figure 23) and bevel lock knob (7). The bevel scale
indicates the angular position of the motor with respect to
horizontal from O0 to 90° in either vertical position. The
latch pin handle (6) outornotically indexes the motor at
0°, 45O and 90° up and down. Lift the latch pin handle to
release. At any other position, the latch pin handle i s not
engaged. The bevel lock knob (7) locks the motor to the
yoke when the motor is i n any position. Rotate it clockwise
to lock; counterclockwise to unlock.
MOVEMENT AND POSITION OF THE YOKE
These are controlled b y the swivel latch pin knob (2, figure
25) and the yoke clamp handle (4). The swivel latch pin
automatically indexes the yoke at each 90° position. Lift
the knob to release. The yoke clamp handle (4) locks the
yokc to the carriage in any position. Pull the handle to
release. Push it to tighten.

PRECISION INDEXING
-
/-
1
-.
Experiencrd operators o f precision equipment, such as this
Craftsman Sow, normally acquire the habit of indexing
the machine in one direction only whenever a new setting
is made in preparation for a different operotion. For example: When moving the radial arm to a new position, i t is
advisable to move it slightly post the desired index position
then move it back slowly a n d carefully to latch and lock it.
(See figure 24). Swivel indexing a n d bevel indexing can
b e accomplished in the some manner. This technique tends
to neutralize any stresses imposed upon saw components
and contributes to the high degree of accuracy this saw is
capable of producing when operated expertly.
REMOVAL OF M O T O R AND
CARRIAGE ASSEMBLY

When the handle moves considerabl y to the rear, or strikes
the yoke before locking, the handle may be adjusted as
follows:
1. Remove saw guard a n d blade.
2. Set yoke clamp handle to Position "A", (figure 25),
which is just slightly ahead of the mid-position of handle.
3. Insert the handle e n d o f the arbor wrench (or shaft

and carriage to raise the carriage stop. (See figure 27.)
The wrench need not b e held, as it will remain in place
when releosed.
4. Grasp the motor a n d carriage assembly and move it
carefully off end o f radial arm.
CAUTION: When removing the motor ond
carriage assembly from radial arm, be sure
to hold the assembly parallel to the arm until
all bearing rollers are free of their tracks.
If the ossembly is allowed t o tilt after the
forward rollers are free, the adjustment of

CROSS-CUTTI NG
Cross-cutting is the sawing of wood across the grain. Lumber
i s milled with the grain running the length of the board. If
a straight cross-cut is desired, the board is placed on the
anti-kickback pawl assembly so i t clears the board to be cut.
Turn key and press the switch "On" to start the saw motor.
Hold the board firmly against the rip fence with the left hand
a n d grasp the bevel index handle with the right hand. The
cut i s then made b y pulling the carriage forward until the
saw blade cuts through the work. When the cut i s complete,
the saw should be returned to the back of the radial arm and
the switch turned "Off". When m o r e experience is gained
by using the saw, i t will b e noticed that w h e n p u l l i n g
t h e s a w t o w a r d you d u r i n g cross-cutting, the saw
b l a d e tends t o feed itself t h r o u g h the w o r k d u e t o the
r o t a t i o n o f the b l a d e a n d the direction o f feed. Therefore, the operator should d e v e l o p the h a b i t o f holding his right a r m straight f r o m the shoulder t o the
wrist. After this method is used a few times the operator
will find that i t i s necessary to roll or rotate the body from
the waist up. Thus, it will become apparent that very little
effort i s required on the port of the operator to move the
saw blade through the work, and in most cases, the right
arm i s used merely to control the rate of feed of the saw
through the board. It will also be found that when crosscutting a thick board it will be necessary to retard rnovernent of the saw through the work. By holding the right
arm (right hand normall y grips the saw handle) straight,
the operator can easily control the rate of feed, thus preventing the saw blade from overfeeding and stalling the
saw motor. This must be avoided whenever possible.
saw table against the fence so that -the grain i s parallel
to the fence. (See figure 32.)
NOTE: When cross-cutting normal pieces of
lumber, the long end of the board should b e
placed to the left of the saw blade as the board
i s normally held by the left hand during operation. The saw i s pulled through the stock - not
pushed through.
The radial arm must be positioned at O0 as indicated by
the radial arm position indicator. The arm latch lever must
be indexed and arm latch handle tightened.

In some cases it may become necessary to. cross-cut long
boards which extend over the saw table on one, or both
sides. 'This can cause buckling of the board and bind the
saw during the cut. To eliminate this condition the ends
of the board should be supported. Figure 33 illustrates a
typical support which can be mode and used to facilituIe
cross-cutting of long lumber.

to attach outboard supports to assist in supporting long
boards, or may be used to pick up the saw (one man at
each side) ond move it. They are also effective for supporting the saw in the bed of a pick-up truck when moving

Holes are located in the saw base that permit legs to be
extended outward horizontally if desired. This i s accomplished by removing three attaching screws in each leg,
rotating the leg to a horizontal position a n d re-installing
the three screws. (See figure 39.) The lower inside screw at
each location need not be removed, but should b e loosened
just enough to permit the leg to rotate on i t as a n axis.

Ripping i s the sawing of wood with the grain. I t is always
done with the help of the fence as a guide t o position and
rnointain the work at the correct width for the cut. Because
the work i s pushed along the fence, i t must have a reosonably straight edge to make sliding contact with the fence.
Also, the work must make solid contact with the toble so
that it will not wobble or rock. Provide a straight edge,
even i f this means temporary nailing or clamping an
auxiliary straight edge board to the work. If work piece
is warped, turn the hollow side up.
Use of the saw guard is always recommended; and the
anti-kickback pawl assembly should always be used i n
both ripping operations.
Before ripping and after the saw has been positioned prior
to cutting, the saw guard a n d anti-kickback p a w l assembly
must be properl y adjusted. Loosen the guard clamp screw
holding the guard to the motor a n d lower the nose o f the
guard fo within 7/8" above the fop surface of the b o a r d
to be cut. Retighten fhe guard clamp screw securely.
CAUTION: The nose o f the guard refers ta that
end of the guard which i s opposite to the end
which mounts the anti-kickback pawl assembly.
Always r i p from the nose o f the guard. See
Warning Label on guard.
At the opposite end of the guard, loosen the wing screw
holding the anti-kickback p a w l assembly a n d lower the
assembly until the tips o f the pawls are 7/8" below the t o p
surfoce of fhe b o a r d t o be cuf. Retighten the wing screw
securely.
The anti-kickback pow1 assembly i s equipped with a "splitter" on its lower end t o prevent the saw slot from closing
and binding the saw blade. (See figure 40.) Therefore, the
anti-kickback pawl must be adjusted so the splitter i s
aligned with the saw blade. This is accomplished by adjusting the two socket-head, set-screws in the guard assembly.
Use a straight edge agoinst the splitter and saw blade a n d
adjust the socket-head set-screws so the splitter is aligned
with the blade when the wing screw i s tightened.

the yoke, d i s e ~ ~ g a gthe
yoke 90' clockwise (viewing it from t ! ~ ecarl.iage) until
,e swivel larch pin automatically indexes the yoke 90'.
.,clock the yoke. Position the motor on the radial arm until
the pointer on the "In-Rip" scale indicates the desired width
of the finished cut board. Tighten the carriage lock knob
securely. Turn the saw "On" and lower the radial arm until
the saw blade cuts into the table top a p proximately 1/32inch. Turn the saw "Off". Now adjust the saw guard and
anti-kick pawl cssembly as described in the paragraph "Ripping". The board to be ripped must be fed into the saw
blade from the right-hand side of the table, therefore, the
normal position for the operator i s also at the right side
of the table. With left hand safely clear of the blade and
holding the board to be ripped down against the table
and against thtt face of the fence as a guide, use the right
hand to feed the board into the saw. The left hand should
remain stationary, serving as a guide only. As the right
hand opprclches the left hand, hold a push stick with
the rigth hand to complete the cut. Do not leave a long
board unsupported so that the spring of the board causes
it to shift on the table. A support (described in "Crosscutting") may be used to support the board behind the
blade; and if the board is very long, use another support
in front of the saw. Ripped boards up to 16-inches wide
can be cut in the In-Rip position.
0
OUT-RIPPING -- refers to a position when the motor i s
between the biode and the fence. Normally, this position
is only used w l ~ e nthe width of the required ripped board
cannot be cut from the in-rip position. Ripped boards up to
17-1 /2-inches wide can be cut in the out-rip position when
.he fence i s agoinst the front table. If the fence is moved to
rre extreme rear position against the table clamps, ripped
boards up to 36-1/2-inches wide can be cut. To place the
saw in the out-rip position, the yoke must be rotated and
indexed 90° counterclockwise from the cross-cut position
and locked. The some procedure for pre-cutting the table
top (see "In-Ripping") ond adiusting the anti-kickback
pawl assembly should be followed. The same procedure
for sawing i s used except that the operator stands at the
left-hand side of the table and a push stick is normally
not required.
Resowing i s cutting thick boards into thinner ones with
a ripping operation. (See figure 42.) Small boards, up to
4-inches maxinlum width can be resawed in one pass;
but larger boards require two passes, one pass along each
edge of the board. When two cuts from opposite edges are
required, these should be made to overlap 1 /2-inch from
the opproximatc center of the board. If the first cut i s too
deep, the kerf may close and bind the saw on the second
cut, with dangcr of kickback. Also, when the kerf closes,
the two sides cf the cut are no longer parallel to the sow
blade, and the saw will cut into them to spoil their appearance. Keep the same face of thc board against the fence
when making both cuts. When cutting boards thicker than
4 inches, a fence should be used which extends 3-1/?-inches
above the table top.
BEVEL A N D MITER CUTS
t3evcl cuts may be made from either a cross-cutting or ripping position b y tilting the blade to the desired angle.
Miter cuts can be made only from a cross-cutting position
when the blade and radial orrn are at some angle other

than 90' to the fence. A bevel miter cut i s a cut which is
both beveled and mitcred. This cut i s made w i ~ hthe blade
and radial arm sct at the desired miter angle to the fcnce;
then the blade only i s tilted ta the desired bevel angle.
This cut i s also referred to as a conipound miter. (See figure 43.)
I
USE OF THE DADO HEAD
The dado saw (or head) i s a special set of blodes for cutting grooves and dodos. Craftsnian 8-inch Kromedge Dado
set may be purchased at any Sears Retail Store or Mail
Order House. The head consists of two outside blades
1/8-inch thick, six 1/8-inch thick chipper blades and paper
washers for 1/16-inch width adiustments. With these blades,
grooves of 118-inch, l/4-inch and, additional widths increased in steps of 1 /16-inch up to a maximum of 1-inch
wide, can be cut. Outside blades may be used alone, chippers cannot be used alone.
When using the maximum width of dado of I-inch on the
motor shaft, the loose collars must not be used. The width
of the dado may be reduced while using the loose collar
and two or more passes made with the work to obtain the
desired width of cut. Whenever two or more chippers are
used, stagger the cutting ends as evenly as possible around
the circumference.
Fractional adjustments in thickness of the head may be
made by using paper washers between outside blades nnd
chippers. Dado head operations are essentially the same
as those with a standard blade. However, the dado head
takes a bigger bite, so the work-piece should be held more
firmly. When a groove wider than the dado head is needed,
make two or more passes. Space the cuts so they overlap a
trifle. Dado work i s performed in the crosscut position.
Ploughing is done in the ripping position. If the rip (or
plough) position is used, the anti-kickback pawl assembly
should be adjusted as described in the paragraph entitled
"Ripping". Rabbeting i s performed in the vertical position.
(See figure 44). When rabbeting, the motor i s indexed 90°
to the vertical position so the blades ore between the table
top and the motor and yoke i s indexed 90° clockwise and
locked. The saw i s moved back on,the radial arm and
locked to the arm when the amount of blade extending
forward of the fence i s equal to the depth of the rabbet
desired. If the depth of the rabbet i s large, do not attempt
to cut i t in one operation. Lower the radial arm until the
blades are in a position to cut the desired width of rabbet
in the edge of the board.

MOLDiNG OR SHAPING
This work is done with the Craftsman Moldin g Cutter Head
and a set of cutters, depending upon the type of molding
cut desired, with the saw in the same position as that described for robbeting. (See figure 45.) Since the position
of the cutters with respect to the fence and table top can
be adjusted, any (or all) of the cutter shapes may be used.

Routing and dovetailing are accomplished with the motor
indexed and locked 90° from horizontal, except the externally threaded stub end (opposite the normal blade end)
is between the motor and table top. The following chucks
will mate with this external 1/2-20 thread. (See figure 46.)
0-inch to 1 /4-inch Key Chuck
5/64-inch to 1/2-inch Key Chuck
The following routers and dovetails ore recommended:
1 /8-inch router
1 /4-inch router
3/8-inch dovetail
1 /2-inch dovetail
3/8-inch router
1 /2-inch router
5/8-inch router
Routing may be performed by either moving the work with
a stotionury router or b y clanlping tire work to the table
and moving the router. Always approach the router b i t
from the lefi-hand side of the saw.

BORING
The saw may be converted to a horizontal drill f o r
by using one of the recommended chucks a n d the
drill. For drilling holes o n a n angle, the radial arm
be positioned to the desired angle while the work
parallel t o the fence. (See figure 47.)

i s held
SANDING
Using the 10-inch sanding disc mounted on the saw end o f
the motor, the saw c a n be converted into a sander a n d
operated in any position. One loose collar should b e used
Jn each side of the sanding disc. (Sce figure 48.)
FENCE LOCATIONS
Tlicre are three positions in which the fence can b e located.
(See figure 49.)
1. Normal position.
2. Position used for maximum crosscut o n one-inch material
a n d for greater bevel and miter capacity.
CAUTION: Rip scales cannot b e used in this
position.
3. Position used for maximum out-rip capacity.
STABILIZING WASHERS FOR THIN BLADES
shoe i s instantly pulled away from the brake lining so the
motor does not start under load. When the motor is turned
off, braking action takes place automatically. This brake
is designed to stop a free running saw blade in 20 t o 25
seconds. DO NOT attempt to alter either the brake disc
or the lining to obtain o faster stopping time. Stopping
the blade too suddenly could possibly unscrew the shaft nut.

HELPFUL HINTS
1. The life of the laminated saw table can b e greatly
lengthened by tacking a piece o f l / d i n c h thick plywood to the table top.
2 . There is a possibility that after tacking a piece o f plywood to the table top, the plywood surface may not
b e smooth or may be uneven. Lay a,straightedge across
the surface of the table a n d check for gaps or high spots
on the table. Any portions of the table that are not
flat may be sanded until flat. Sanding can b e accomplished in the manner shown i n figure 48.
3. When sanding on the table top, or routing with fhe
work stationary, the arm lock pin can be prevented
from automaticoily indexing a t O0 and 45' by rotating
the arm latch handle approximately six turns counterclockwise from the locked position.
Stabilizing washers should be used with blades for improved appearance of the finished cub.
4. A scale may b e provided to a i d the operator when
measuring lengths during cross-cut. operations, by tacking or gluing a yard-stick or wood scale to the fence as
..
shown. (See figure 50.)
BRAKE
5. In the event o f a warped fence that cannot b e straight-
The motor o f this saw i s equipped with a built-in electromechanical brake t o eliminote a lengthy "coast" time after
the saw is turned off. W h e n the motor is started, the brake

ened b y tightening the table clamps, remove the fence
and install a new fence cut t o the same size from a
piece of straight stock.
