CONNECTING MOTOR TO POWER SUPPLY

The a-c motor used in this Craftsman Radial Saw is of

the capacitor start, non-reversible type with the following specifications:

Voltage .......................... 120

Amperes ......................... 9.5

Cycle ............................ 60

Phase ......................... Single

RPM ............................ 3450

Rotation (viewing saw blade end) Clockwise CAUTION: This motor is wired for 120 volt

operation. Connect to 15 ampere branch circuit and use a 15 ampere time-delay fuse.

MOTOR SAFETY PROTECTION

The saw motor is equipped with a manual-reset thermal

overload protector, designed to open the power line circuit when the motor temperature exceeds a safe value.

1. If the protector opens the line and stops the saw motor, press the saw switch to the "OFF" position immediately

and _llow the motor to cool.

2. After cooling to a safe operating temperature, the overload protector can be closed manually by pushing in the red button on the motor capacitor cover. If the red button will not snap into place immediately, the

motor is still too hot and must be allowed to cool for a

while longer. (An audible click will indicate protector

is closed.)

3. As soon as the red button will snap into running position, the saw may 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 is overloaded, or if the motor circuit is fused

with a fuse other than those recommended. Do not use a fuse of greater capacity Without consulting the power company.

5. Although the motor is designed for operation on the voltage and frequency specified on motor nameplate, normal loads will be handle d safely on voltages not more

than 10% above or below the nameplate 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 circuit) or when the supply circuit is 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 paragraph.

MOUNTING THE SAW ON A WORK BENCH

The sow shoud be placed on a suitable sturdy work bench, or Craftsman Power Tool Bench. The base of the saw must

be mounted *lush to a flat surface on the work bench to prevent distortion of the saw base. The nuts, screws, and

washers which attach the wooden shipping skids to the saw base may be used to secure the saw base to the work

bench, or tact bench.

ALIGNMENT INSTRUCTIONS

NOTE: The seven basic "steps" that follow are essential in order to insure correct saw table

alignment.

WARNING: Make sure the power cord is not plugge d into an electrical outlet when

working on the saw.

STEP ONE--INSTALLATION OF FRONT TABLE

1. Place the large table board upside-down on floor. Distinguish between the one through-bored (leveling

screw) hole near the center of the board, and the seven counterbore holes. (See figure 2.) The counterbores are in the top surface of the board. Drive the T-nut into the through-hole. (See figure 3.)

2. Place the 1/4-20 "'U" clip nut on the base cross members to receive the center front tab!e attaching screw.

3. Place the large, front table board on table support angles.

4. Align the counterbore holes with matching holes in the support angles. Place a flat washer and a 1/4-20x 1"

pan-head machine screw in each of the six counterbore

holes located above the angles. Use a 1/4-20 x 1-1/4 '_

pan-head machine screw in the counterbore hole at the center of the table board.

5. Start the leveling screw into the T-nut but do not allow the point to protrude beyond bottom surface of front

board.

6. Install Iockwashers and nuts on the six screws in the angles and tighten them finger tight. Start the 1/4-20 x

1-1/4" pan-head screw in the counterbored hole near

the center of front board, leaving it about two turns loose.

STEP TWO--ELIMINATING RADIAL ARM SIDE PLAY

1. Set the radial arm at 0 J index position, making sure the arm latch handle is in the detent notch, and tighten the arm lock handle. (See figure 4.)

2. Apply side force with one hand on radial arm in both directions. If side play exists, an adjustment is required.

3. Insert a 3/16-inch Allen wrench into the socket-head

set-screw that adjusts the column tube wedge key, as shown in figure 4. Rotate the set-screw slowly in (clock-

wise) until no side play can be felt in radial arm.

4. Check for binding by rotating the elevation crank. If the crank rotates with noticeable resistance, loosen the set

screw by rotating the Allen wrench counterclockwise until rotation is normal. An effective method for finalizing the set-screw adjustment is to rotate the screw while the elevation crank is being rotated, checking for side play in radial arm as the adjustment progresses. The adjust- ment is correct when all side play of radial arm is eliminated and only very slight additional resistance

can be felt when rotating the elevation crank.

5. If some radial arm side play can still be detected after performing the above adjustment, it will be necessary to adjust the forward five screws through the right, and

left-hand (olumn supports as follows:

a While -otating the elevation crank, tighten the five

of column supports. Each screw should be tightened only slightly, and each one the same amount, until a

slight resistance con be felt when rotating the eleva- tion crank, then each screw backed off just enough

to restore a normal feel to the elevation crank.

b. Recheck the adjustment of the column tube wedge

key set-screw as outlined in preceding instructions.

6. After the above adjustments have been completed, recheck the radial arm for absence of side play.

7. When all side play has been eliminated, lock the column

tube key in place by tightening screws at top and bottom of key. (See figure 4.)

STEP THREE--SQUARING THE CROSS CUT TRAVEL

1. Set the radial arm at 0 :' index position and tighten the arm lock handle. (See figure 4.)

2. Place a square on the table as shown in figure 5 and position the saw and square until the leg of the square

just contacts a tooth of the saw blade. (Position "A-, figure 5.) Mark this tooth with crayon or chalk.

3. When the blade is moved back and forth on the radial arm, the saw tooth "A" should just touch the square at

all positions. If saw tooth "A" does not touch the square at all points, make the following adjustments.

If saw tooth ("A", figure 5) moves away from the square when moving the blade from the rear toward the front of the table, loosen the table screws at the

left side and tap the rear edge of front board forward until the table is square with the saw blade. (See

figure 6.)

Recheck blade squareness and, if correct, tighten the

six ta!_le screws.

Reverse this procedure if tooth "A" moves into the

square when moving the saw table from the rear toward the front of the table.

4. In extreme cases, due to rough handling during ship- ment, performing the above adjustment procedure may not be sufficient. Make the fallowing adjustment only

after tightening the table screws and the cross-cut travel cannot be squared by performing the preceding adjust-

ment routine: a. Position the radial arm in 0 position, press arm

la_ch handle down firmly into the detent notch. (See figure 7.)

Using a 1!8-inch Allen wrench, loosen the two set screws that lock the arm latch screws.

Move saw blade forward along steel square to deter-

mine in which direction the arm must be adjusted.

If the saw blade moves away from the square as it cemes forward, loosen the front arm latch screw and tighten the rear arm latch screw. Check blade travel

arid repeat if necessary.

If the saw blade moves toward the square as it comes forward, loosen the rear arm latch screw and tighten

the front arm latch screw. Check blade travel and repeat if necessary.

f. When the adjustment is correct, both arm latch

screws should be snug against the arm latch handle but not tight enough to bind the handle.

g. Tighten the Allen set-screws to secure the arm latch

screws.

5. After the cross-cut travel has been accurately squared, check the 0 ° position on the indicator scale of the radial

arm cap to determine if the 0 ° position on the scale is aligned with the index mark on radial arm. (See figure

8.) If not aligned, proceed as follows: a. Rotate the elevation crank to a position that will

locate the two access holes over screw heads of radial arm cap attaching screws. (See figure 8.)

b. Loosen the two screws with a screwdriver inserted

through the access holes in lift crank.

c. Reposition the radial arm cap by hand until the

0: mark is aligned with the index mark and tighten the two attaching screws.

STEP

FOUR--LEVELING THE TABLE PARALLEL

TO THE RADIAL ARM

NOTE: DO NOT USE A CARPENTER'S LEVEL.

Remove the saw guard.

Raise the arm latch handle out of the detent, loosen

the arm lock handle (figure 4) and loosen the carriage

lock knob (4, figure 1). This will permit easy positioning

of saw blade during leveling operations.

Lower the saw blade by rotating elevation crank until a tooth just touches the table at the highest spot when saw

is moved to points 1,2, 3, and 4 (POSITION 1, figure 9). This will locate the table high point. Spin the saw Blade by hand and listen for "pinging'" sound to pick up this high paint.

Loosen the table support screws at each side just enough to allow the table support angles to slip when tapped with a mallet. (See figure 6.) If too loose, leveling

operations will be difficult.

NOTE: Do not change elevation of saw blade

during remainder of the leveling operation.

Move the saw blade to the low position opposite the high point (located in step 3, above) at the same end of table. Assuming the high area to be at point 1 (POSITION 1, figure 9) the Blade would next be moved to point 3 (POSITION 2, figure 9).

Using a mallet, tap the table support angle under point 3 until the table top just touches the saw blade.

Tighten the two table support screws securely at the left side of frame (figure 6), and recheck by moving saw blade back and forth between points 1 and 3 (POSI- TION 2, figure 9). If this end of table surface is level, the saw will just touch the table at points from 1 to 3. If not level, readjust point 3.

Move the saw blade to point 2 (POSITION 3, figure 9). Tap forward end of right table support angle upward

with a mallet until the blade just touches the table surface.

Move the saw blade to point 4 (POSITION 4, figure 9) and tap rear end of table support angle upward until the blade just touches the table surface.

10.

Tighten the two table support screws securely at the right side of frame (reference figure 6), and move saw blade back and forth between points 2 and 4 (POS!- TION 4, figure 9) to make sure it touches at all posi-

tions from points 2 and 4.

11.

Recheck the adjustment by moving saw blade to points

1, 3, 2 and 4 and make corrections if necessary.

-oo

12. After preceding leveling operations are complete, move saw blade to the center of table to check for proper

POSITION

POSITION

table height at points 5 and 6 (POSITION 5, figure 9). The table attaching screw at point 5 pulls table down- ward when tightened and the leveling screw at point 6 pushes table upward when tightened (provided screw at point 5 has been loosened). Thus, these two screws work against each other to adjust the center area of saw table. Both screws should be tight, however, when leveling has been completed.

13. Place the rip fence in vertical position behind the front table board.

14. Place the table spacer board behind the rip fence.

15. Place the rear table behind the table spacer board.

16. Install the table clamps at locations shown in figure 2 and tighten them firmly against the edge of rear table.

STEP FIVE--SQUARING THE SAW BLADE

TO THE TABLE TOP

1. Place the edge of a framing square on the table top

and against the saw blade as shown in figure 10.

2. When the saw blade is square to the table top, no light

will be visible between the square and face of saw blade. Do not allow the square to rest against a tooth of the saw. If light is visible between the square and face of saw blade (with square leg held firm against the table top), perform the following adjustments.

a. Loosen the bevel lock knob just slightly and with

a 5/16-inch Allen wrench loosen the two socket-head screws that secure the handle to the yake. (See figure

11.) A screw is located at each side of the swivel index knob.

b. While holding the motor with one hand and the

square with the other hand, tilt the motor until saw blade is square with table top. Then, while holding

the square firmly against the saw blade and table top,

tighten the bevel lock knob to hold motor and blade in position.

c. Move handle slightly toward left or right until swivel

index pin is properly seated. Push firmly against

swivel index knob (keeping swivel index pin seated)

and tighten the two socket-head screws. The swivel

index pin should slide freely in the handle. NOTE: It may be necessary to perform more

than one trial operation before the saw blade

remains perfectly square with table top after

tightening the screws. d. Recheck for blade squareness with table top. e. The indicators (pointers) should read 0 ° on the bevel

scale. If not, loosen the indicator attaching screw,

adjust indicators to zero and tighten the screws

securely.

STEP SIX--CHECKING THE SAW BLADE FOR

HEEL (LEFT AND RIGHT)

1. Place a square against the rip fence and the saw blade as shown in figure 12. The long leg of the square must

be held firmly against the rip fence and the short leg

must not touch any of the teeth on the saw blade.

2. If a gap exists between the saw blade and the square, one of two types of "heel" exists. The two types of "heel"

are illustrated in views "A" and "B", figure 13. To correct

for either type of "heel" condition, proceed as follows: a. R,-move the left-hand carriage cover by removing the

two attaching screws.

Remove the right-hand carriage cover by first remov- ing the carriage lock knob (4, figure 1), by screwing

it all the way out. Then remove the two attaching screws to free the cover.

c. Loosen slightly the carriage bearing retainer nut just

abave the left rear carriage bearing. Then loosen slightly the corresponding nut over right rear car-

riage bearing.

NOTE: These nuts shauld be loosened just enough to permit the carriage bearing screws to

slip in their holes.

d. If the heel is in the direction shown in "View A" (fig-

ure 13), insert a 1/8-inch Allen wrench and loosen the set-screw at left rear position, then tighten set- screw at right rear the same amount. (See figure 14.)

NOTE: As one set screw is loosened, the oppo- site one should be tightened the same amount

in order to retain the carriage bearing adjust- ment as accurately as possible.

e. If the heel is in the direction shown in "View B" (figure

13), loosen the right rear set screw and tighten the

left rear set-screw the same amount. (See figure 14.)

f. After the heel has been corrected, tighten the rear

carriage retainer nuts and check for proper tension of carriage bearings on the tracks.

g. If front carriage bearings need adjusting for proper

tension on the tracks, the adjustment is made on the right front carriage bearing. Loosen (slightly) the carriage bearing retainer nut and rotate the set screw

until tension is correct. After the tension has been corrected, tighten the carriage bearing retainer nut.

(The adjustment is correct when there is no side play between the arm and carriage, and the car- riage moves forward and rearward with very slight

resistance.)

h. Install both carriage covers and carriage lock knob.

STEP SEVEN--DOUBLE CHECK SQUARING OF SAW

1. Recheck for correct adjustment of the saw by perform- ing "STEPS ONE through SIX".

2. If the cross-cut travel is not perfectly squared, proceed with "STEP THREE" and make all adjustments listed in the "STEP THREE" procedure.

MAKING PRELIMINARY CROSS-CUT

AT THE 0 ° POSITION

1. Attach saw guard assembly to the motor and tighten the guard clamp screw ta secure the guard. (See figure 15.)

2. Pull motor forward of fence so that saw blade is free to rotate.

3. Lower the radial arm until saw blade just clears the table top.

4. Tighten carriage lock knob (4, figure 1).

CAUTION: Before cutting always be sure that the arm latch handle is fully engaged in detent

notch.

5. Plug the power cord into receptacle.

6. Insert safety lock key, turn the key and press the switch to "'ON" position. (See figure 19.)

7. Lower the radial arm until saw blade cuts into table

top 1!32-inch deep. THIS IS ALL THAT IS NECESSARY.

8. To complete a blade clearance groove in the table and

fence hold the handle with the left hand and loosen the carriage lock knob with the right hand. Slowly pull

the motor with the left hand out to the extreme end of

INSTRUCTIONS FOR USE OF KEY AND SWITCH

1. Insert the key into the slot and turn counterclockwise.

(See figure 19.)

2. Press the ON-OFF switch toggle on the right end to start the saw motor. Press the left end of switch toggle to

stop the saw.

NOTE: This saw can not be operated without

the key, and likewise, the key can not be re- moved from the lock while the saw motor is

running. This locking system was designed for safety and protection of the operator.

RAISING AND LOWERING THE RADIAL ARM is accom- plished by the elevation crank (5, figure 18). One complete

turn of this handle will raise or Iowerthe radial arm 1/8-inch. LOCKING THE CARRIAGE TO THE RADIAL ARM is ac-

complished by the carriage lock knob (4, figure 18). Turn the knob clockwise to lock; counterclockwise to unlock.

Avoid excessive tightening of the knob.

ANGULAR MOVEMENT AND LOCKING THE RADIAL ARM are controlled by the arm lock handle (7, figure 18)

and the arm latch handle (8). This handle is used to lock the arm to the column for normal cutting. It should also be

used to eliminate any play between the arm and the column when levelling the table (Refer to STEP FOUR). This is done

by tightening the arm lock handle until the arm is snug on the column, thus eliminating looseness and allowing the

arm to rotate smoothly. The radial arm can be rotated

360 and locked ;n any desired position. The arm is un-

locked by loosening the arm lock handle and raising the

arm latch handle out of the detent notch. It is locked by tightening the arm lock handle. The radial arm has positive stops at 0 ° and 45 ° , left and right, and is released from these index positions by raising the arm latch handle.

In order to provide the most positive and accurate se_ings at the index positions, the fo!/owing is recommended.

1. If the radial arm is already indexed, raise the arm latch handle, turn the arm lock handle (7, figure 18) ap-
