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.

BEFORE MOUNTING, DISCONNECTING OR REMOUNTING THE MOTOR; unplug the saw and

remove the switch key.

k WARNING: When servicing, use only identical

Craftsman replacement parts. Use of any other parts may create a hazard or damage product.

NEVER USE THIS TOOL IN AN EXPLOSIVE

ATMOSPHERE. Normal sparking of the motor

could ignite fumes.

MAKE SURE THE WORK AREA HAS AMPLE

LIGHTING to see the work and that no obstruc

tions will interfere with safe operation BEFORE

performing any work using this tool.

DO NOT USE TOOL IF SWITCH DOES NOT

TURN IT ON AND OFF. Have defective switches

replaced by a qualified service technician at a Sears repair center.

GUARD AGAINST ELECTRICAL SHOCK by

preventing body contact with grounded surfaces such as pipes, radiators, ranges, refrigerator enclosures,

hand to move into the blade. ALWAYS make sure you have good balance.

CRflFTSMfir RADIAL SAW 315.273731

Page 6

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.

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.

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.

CHANGING VOLTAGE

See Figures 2-4.

Your radial saw has been set up at the factory to operate efficiently on a 120V AC single voltage circuit. However, if heavy duty operation is required, the circuits are overloaded, or the circuit is low voltage, have a qualified electrician change the voltage on the main power system to a 240V AC voltage circuit.

A WARNING: The control cut device is set up for

a 120V AC single voltage circuit. Do not modify the control cut cord. Identify the control cut cord and tie it back out of the way.

■ Correctly identify the control cut cord, unplug it, and set it aside.

■ Unplug the main power cord.

■ Remove the blade following the procedure in the Assemb/y section.

■ Remove the pan head screw above the blade arbor on the motor cover. Lift motor cover to expose switch. See Figure 2.

■ Use a small screwdriver to slide the dual voltage switch to the 240V position. See Figures 3 and 4.

■ Reinstall motor cover.

■ Replace the 120V plug on the main cord with a UL listed 240V, 15 amp, 3-prong plug.

■ Follow the instructions provided with the UL listed plug.

■ Plug the cord into a 240V, 15 amp, 3-blade recep tacle. Make sure the receptacle is connected to a 240V AC power supply through a 240V branch circuit that has a 15 amp fuse or circuit breaker.

Note; No adapter is available for this type of plug or

receptacle.

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 set up or on a frequent basis can result in poor performance or machine damage.

SETTING THE ARM LOCK KNOB

See Figure 15.

It may be possible to move the arm when locked, if the arm lock knob is too loose. If the arm does not move freely when unlocked, the arm lock knob may be too tight. Use this procedure to check and set the arm lock knob by turning the arm lock wheel (under the carriage arm).

■ To release the arm lock knob, located on top of the arm at the front, pull the arm lock knob forward until the spring is compressed.

■ While holding the arm lock knob forward, swing the arm 30" to the left or the right, referring to the miter scale on top of the column.

■ Lock the arm in place by pushing the arm lock knob back until it pops in the locked position.

■ Apply a reasonable amount of pressure on the arm. The arm can be forced, but if it moves easily, it needs adjustment.

■ Locate the arm lock wheel.

■ Release the arm lock knob and turn the lock wheel clockwise to tighten or counterclockwise to loosen,

■ Repeat above steps until the arm movement is minimized when locked.

Lock the yoke lock handle. Grasp the motor with both hands and apply reasonable pressure to see if it slips. If it moves, reset the yoke lock handle as

follows.

Remove the arm cap screws and arm cap at the

front of the arm with a phillips screwdriver. See

Figure 16B.

Remove the carriage stop screw and lockwasher

with a 1/4 in. hex key. Carefully slide the yoke

assembly forward and off the carriage. Place the yoke assembly in a spot where it will be

secure as you work on the top of the yoke. Release the yoke lock handle. Tighten the center

nut with a 15/16 in. wrench until the lock handle is centered between the two legs of the yoke.

Carefully replace the yoke assembly on the car riage arm track. Slide it back about halfway.

Replace the carriage stop screw and lockwasher,

followed by the arm cap and arm cap screws.

Lock and test the yoke again. If it can be moved, repeat the procedure until it is secure.

SETTING THE YOKE CLAMP

See Figures 16A and 16B.

The yoke clamp keeps the yoke from rotating on the carriage when you want the saw blade to be station ary. Use this procedure to check and set the yoke clamp.

■ Release the yoke lock handle (below the arm on the right side) so the motor can be rotated.

■ Swivel the motor slightly. It should be at an angle in between one of the preset positive stop angles.

ASSEMBLY

SETTING THE BEVEL LOCK LEVER

See Figures 17A -17C.

The bevel lock lever locks the blade at desired angles other than the preset positive stop angles. The bevel lock lever is preset at the factory but may need readjustment after shipping or extended use. Check

for overtightness or looseness and make any neces

sary adjustments as follows: The bevel lock lever is located on the front of the yoke

assembly, near the bottom. It is attached to a clamp bolt that controls the amount of tightness.

■ Pull the bevel lock lever forward to unlock it. Use the bevel index knob (just under the handle) to rotate the motor approximately 30°, Lock the bevel lock lever,

■ If the bevel lock lever is difficult to lock, the clamp bolt needs to be loosened. If the motor can be forced out of position, the clamp bolt needs to be tightened.

■ Remove the socket screw (under the bevel lock lever) and star washer with a 1/8 in. hex key.

■ Use the bevel lock handle as a wrench to tighten or loosen the clamp bolt. The clamp bolt has a right handed thread. Tighten it left to right.

■ When the bolt is correctly set, remove the bevel lock lever from the clamp bolt and place it roughly parallel to the yoke assembly.

■ Replace the socket screw and star washer. Re check the tightness of the bevel lock lever. Repeat the steps above until the motor is secure when locked, and the bevel lock lever fits squarely against the yoke assembly.

jIqHjEning the arm and column

See Figure 18.

There should be no play, vertical or horizontal, in the arm relative to the column. If you can move the arm up, down or sideways when the arm lock knob is unlocked, use the following steps to tighten the arm.

Note: The arm should pivot only when the arm lock

knob is unlocked and pulled forward to com press the spring.

■ Using a Phillips screwdriver, remove the rear cover screws (2) and rear cover from the back of the arm. This uncovers the bolts on the column.

■ Tighten the top two bolts evenly until the arm is firm and there is no vertical or horizontal movement.

■ Also check the two bottom hex nuts. It is not necessary to tighten them as tight as the upper bolts. However they should be tightened even and snug.

■ Replace the rear cover and rear cover screws.

■ Tighten screws securely.

ADJUSTING THE COLUMN TUBE

See Figures 19A - 19D.

The purpose of this procedure is to check whether the inner column tube is snug in the housing and to remove any looseness. Looseness could result in a poor cut or difficulty in elevating the carriage. The column tube is the upper portion of the column and

extends from the column support. Note: It is criticano remove all looseness with this

procedure. If this procedure is not done cor rectly, following adjustments will be wrong and

could result in machine damage.

This procedure checks both the elevating action and the rotating action. If a check does not show loose ness, do not perform the adjustment,

■ If the arm is not at 0' (straight forward), release the arm lock knob, set the arm, and re-lock the arm

lock knob.

■ Elevation check: To check the elevation movement,

place your hand under the front of the radial arm. Press upward on the radial arm. There should be no play between the column tube and the column

support. The whole assembly should move as one.

See Figure 19A.

ASSEMBLY

Rotation check: To check the rotation, hold the front of the arm with one hand and grasp the top of the column support with the other. Press the arm to the side. If there is play between the column support and the column tube, it needs to be adjusted. See

Figure 19B.

COLUMN TUBE

Eievation Adjustment: If the elevation check did not show any play between the column tube and the support, go to the rotation adjustment. Otherwise, raise and lower the arm with the elevating hand wheel. Tighten the black screws on the right side of the column support by 1/16th to 1/8th of a turn. Tighten the two silver screws on the left side slightly more. You will need two 1/2 in. wrenches or sockets. Turn the elevating handwheel again. If the column tube binds, loosen the silver and black screws and turn the handwheel again. See Figure

19C.

When the elevation is smooth, check for looseness again by pressing upward on the front of the arm.

Repeat the previous step until elevation is smooth

with no play between the column tube and the column support.

Eievation Adjustment

Rotation Adjustment: Using a 3/16 in. hex key,

slightly tighten the two cap screws at the back of the column support (left side) until no play shows

between the radial arm and the column. The cap

screws are indicated by arrows. See Figure 19D.

Recheck the rotation by holding the front of the arm, grasping the top of the column support with the other, and pressing the arm to the side.

ADJUSTING THE CARRIAGE BEARINGS

See Figures 20A and 20B.

Loose carriage bearings permit the blade to wander slightly while cutting, which will result in a poor cut and more wear and tear on the saw. Use the following steps to check for tightness and to then adjust the bearings if needed.

■ On the left side of the arm, remove the carriage lock knob, the carriage cover screws, and the carriage cover.

■ With one hand, grip the front bearing hard to keep it still, and pull the carriage forward with the other hand. The bearing should turn. If it stays still as the carriage is moved, it needs to be adjusted.

CARRIAGE BEARING

■ Use a 9/16 in. wrench to hold the eccentric screw (top of bearing) and a 1/2 in. wrench to loosen the nut below the bearing.

■ Turn the eccentric screw a partial turn as needed to

tighten the bearing.

■ Retighten the nut and repeat the second step to

test the tightness. Adjust it so the bearing turns even against resistance when the carriage is

moved - but not so much that the carriage is difficult

to move and return it to its rear position.

■ Repeat for the left rear bearing.

Note: Adjust bearings on the left side only. Bearings

on the right side do not adjust.

■ Replace the carriage cover, carriage cover screws,

and carriage lock knob.

LEVELING THE TABLE SUPPORTS

See Figures 21A and 21B.

The table supports must be perfectly level.

■ Pull the bevel lock lever forward to unlock it. Use the bevel index knob to rotate the motor so the arbor shaft points down. Lock the bevel lock lever.

■ Release the arm lock knob to angle the arm. Begin by positioning the arbor shaft over the back of the highest table support. Normally this is the left side.

See Figure 21 A.

■ Lock the arm lock knob and the carnage lock knob.

■ Using one of the blade wrenches as a feeler gage, place it on the table support below the arbor shaft.

■ With the elevating handwheel, carefully lower the motor until the shaft just touches the wrench. The wrench should move with only slight resistance. Securely tighten the back screw on the table support.

■ Without changing the elevation, move the arm to place the blade arbor over the front of table sup port. See Figure 2 IB.

Place the wrench below the shaft and check that the clearance is the same. If not, adjust the table support until it is the same. Securely tighten the front screw.

Move the arm to the opposite side and repeat the above procedure. When the opposite side is level,

recheck the first side to make sure that it is still accurate and even.

ALIGN RIVING KNIFE TO BLADE

See Figures 26A - 26C.

When ripping the riving knife must be centered with the blade to ride in the middle of the kerf and keep it

from binding. Binding pinches the blade. Blade

pinching can cause kickback. There are two pairs of anti-kickback pawls.

^ WARNING: Failure to use the riving knife, hold

downs, and anti-kickback pawls can allow kickback. Kickback can throw the workpiece toward the operator, resulting in serious injury.

■ Put the blade to the in-rip position by first loosening the yoke lock handle, below the carriage on the right. Then pull the yoke pivot latch (right side of arm, on carriage) forward and rotate the yoke to the left. This indexes the yoke 90" so the blade is between the motor and the column. Lock the yoke lock handle.

RIVING KNIFE

With the elevating handwheel, lower the arm until the blade just clears the table.

Support the lower outer blade guard and loosen the carriage lock knob on the left of the arm. Move the yoke back until the blade touches the fence. Reset the carriage lock knob.

Loosen the riving knife knob, at the front of the

upper blade guard. Lower the riving knife to the table and tighten the knob. If the knife rests against the fence, with one set of pawls riding on the fence,

no adjustment is needed.

INSTALLING RIP SCALE INDICATORS

See Figure 27.

The rip scale indicators on the arm show the distance between the blade and the rip fence with the fence in the front and rear positions. The upper scale is used when the fence is positioned directly behind the front table. The lower scale is used when the fence is at the extreme rear, directly in front of the column.

The In-Rip Indicator is on the right side of the arm. The Out-Rip Indicator is on the left side of the arm.

■ Remove the following from a small hardware bag. 2 rip scale indicators

4 screws

2 speed nuts

■ On the left of the radial arm saw, remove the carriage lock knob and spring.

■ Remove the two carriage cover screws and the carriage cover.

■ Insert a speed nut inside the carriage cover with the flat side up. Place the scale indicator on top of the carriage cover and attach with two screws. Se curely tighten screws.

■ Replace the carriage cover and tighten the carriage cover screws.

■ Replace carriage lock knob and spring.

■ Repeat for the right side.

SCREWS

To complete setting up your saw, continue with the Adjustment procedures. The adjustments should be checked regularly, depending on usage. Your saw will provide accurate cuts with fine tolerances as long as you protect the accuracy with frequent alignment checks. The radial arm saw can perform a wide range of high quality cuts.

The final step will be connecting the control cut device. The control cut device offers many benefits. As it increases operator control, it eliminates the risk in a cross cut of the saw “climbing" out and over the workpiece at the operator. Feed control of the blade as it cuts through the workpiece increases, as does the accuracy of the cut. The following adjustments need to be completed before the control cut device is connected.

ADJUSTMENTS

Your radial arm saw is designed to perform a variety of complex cuts with fine tolerances, A weekly align

ment check ensures that your saw can perform with precision. It takes about ten minutes and the results is better performance and a longer life for your saw.

Perform the checks in the order given. If you miss an

adjustment, go back to the missed adjustment and

repeat all steps from that point forward.

ERflPTSMHi* RADIAL SAW 315.273731 34

CAUTION; Failure to check alignments and

perform the adjustments in the initial set up or on a frequent basis can result in poor performance or machine damage.

ALIGNING THE ARM FOR CROSS CUTS

See Figures 28A - 28 C.

This procedure checks whether the arm is exactly 0' for cross cut travel by checking the blade against the table and the miter indicator. Remove the rear table, spacer table, and fence, but leave the front table in place. You will need a framing square, a 3/16 in. hex key, and a pencil.

WARNING: Be sure the saw is unplugged

before performing these adjustments. Accidental start-up could result in serious personal injury.

■ First check the framing square by fitting one side against the back edge of the table. Lightly draw a

line on the table along the edge of the square in the middle of the table. Flip the square over. If the edge still matches the line with no gaps or over

laps, the square is true.

Release the arm lock knob. Position the arm

straight forward (0") and leave it unlocked.

Lower the arm with the elevating handwheel until the saw blade just clears the front table. Lock the yoke lock handle (right side of saw, below yoke) and the bevel lock lever.

Place the framing square on the table and position one edge of the square firmly against the back edge of the table. Position the other leg of the square against the blade until it rests beside but not touching a tooth. With a pencil, mark beside this tooth.

Slowly move the yoke assembly forward and

backward along the arm and against the square without rotating the blade. If the mark moves into or away from the square, adjust the arm with the following steps.

At the back of the column, loosen the three set screws with a 3/16 in. hex key and position the arm as needed to align with the framing square.

Lock the arm lock knob and retighten the three setscrews. Recheck the cross cut travel with the

blade against the framing square. Set the miter indicator on top of the column to 0".

Replace the fence, spacer table, rear table, and table clamps.

See Figures 29A - 29D.

This procedure squares the blade to the table at 0" bevel (vertical) so the blade angle will be accurate. If the blade is not at 0" bevel, follow the steps below to rotate slightly. You will need a framing square and a 1/4 in. hex key.

■ Position the blade in front of the fence. Lower the blade with the elevating handwheel until it just clears the front table.

■ Lock the following controls:

bevel lock lever below the handle, carriage lock knob on the left side, arm lock knob on top of the arm, and yoke lock handle below the yoke, on the right.

■ Stand a framing square on the table with the short leg pointing up against the saw blade and the long leg parallel to the fence. Place the square flat against the blade between two teeth.

■ If both the top and bottom of the saw blade are flat against the square, no adjustment is needed.

■ If the saw blade gaps at the top or bottom, remove the bevel index cap by removing the two phillips head screws (below the handle). You will see four socket head screws.

■ Loosen the socket head screws with a 1/4 in. hex key. Rotate the motor slightly while holding the square against the saw blade and table top.

■ Slightly tighten each of the four screws and recheck the blade and framing square.

If there are no gaps, fully tighten each screw. If

there is still a gap, repeat the previous two steps.

Check the bevel indicator on the yoke assembly near the handle. It should read 0". If it does not, reset it by loosening the screws and rotating the bevel index cap. Retighten the two screws.

SQUARING BLADE TO FENCE

See Figures 30A - 30C.

This procedure squares the miter angle of the blade to the fence to reduce the risk of binding and kickback. If the blade is not square to the fence, the yoke assem bly must be rotated slightly. Have a framing square, a 1/2 in. wrench, and a phillips screwdriver at hand. The blade should be lowered to just clear the table. Release the carriage lock knob.

WARNING: The blade must be angled at 90° to

the fence when the handle is at the front of the saw. If not, kickback could result during a cross cut. Kickback can cause serious injury by throw ing the workpiece toward the operator. In addi tion, a faulty miter angle on the blade can splinter or burn the cut edges of the workpiece during cross cuts or rip cuts.

■ Use the arm lock knob to index and lock the arm in 0° miter position (straight forward),

■ Pull the yoke assembly forward to the front of the arm. Lock the carriage lock knob.

■ Place the short end of the framing square against the fence. Rotate the square to 45° to the table.

Place the long edge across the flat surface of the blade, below the center of the blade. (Do not place the edge against a tooth.)

■ Check whether the blade is flat against the edge for the entire length or whether a gap is visible.

■ If the blade needs adjustment, remove the right side carriage cover with a phillips screwdriver.

Release the yoke lock handle (below the yoke on the right). With a 1/2 in. wrench, slightly loosen the two hex bolts holding the yoke pivot latch.

Rotate yoke assembly until the gap is eliminated.

Lock the yoke lock handle. Retighten the two hex

PARALLELING BLADE TO TABLE

See Figures 31A-31C.

This procedure squares the blade to the table at 90" bevel so horizontal cuts will be accurate. This also reduces kickback, as well as splintering and burning of the cut edges of the workpiece. If the blade is not at 90" bevel, follow the steps to rotate the blade unit slightly. You will need a framing square and a flat blade screwdriver.

WARNING: The blade must be perfectly parallel

to the table at the 90" reading on the bevel scale.

If not, kickback could result, as well as splinter ing or burning the cut. Kickback can result in serious personal injury as the workpiece can be thrown at the operator.

■ Use the arm lock knob to lock the arm in 0° miter position (straight forward),

■ Turn the elevating handwheel to raise the blade at least 2 in, above the table,

■ Release the bevel lock lever below the handle. Use the bevel index knob, just under the handle, to turn the motor to 90". The blade will be horizontal. Lock the bevel lock lever.

■ Place the framing square with the short end hang ing down in front of the worktable and the long side on edge under the blade.

■ Lower the arm with the elevating handwheel so the blade surface rests on the square. Turn the blade slightly if necessary so the face of the blade, not a tooth, lies on the square.

Check whether the blade is flat against the edge the entire length or whether a gap is visible. If you can see a gap, adjust the blade to be at 90" bevel to the table with the following steps.

Unlock the bevel lock lever. Loosen the rear motor

mount nut, which holds the motor on the yoke.

Place a flat blade screwdriver in one of the slots, and rotate the cam behind the nut to eliminate the gap between the blade and the square.

Retighten the nut. Tighten the bevel lock lever. Recheck the blade

and the square for any gaps.

Raise the blade with the elevating handwheel to approximately halfway up. Index the blade to a vertical 0" bevel with the bevel index knob. Lock it with the bevel lock lever.

ALIGNING THE RIP SCALE INDICATORS

See Figures 32A - 32B.

The rip scale indicators on the arm show the distance between the blade and the rip fence. The upper scale is used when the fence is positioned directly behind the front table. The lower scale is used when the

fence is at the extreme rear, directly in front of the

column. The in-rip indicator and scale are on the right side of

the arm. The out-rip indicator and scale are on the left side.

This procedure checks the indicators with the fence at the back of the tables directly in front of the column. The blade should be turned to the in-rip position to set the rip scale indicator on the right side of the arm. Then, the blade should be turned to the out-rip position to set the rip scale indicator on the left side of the arm. You will need a framing square.

■ If the fence is not at the rear of the tables, place it there.

■ Turn the blade to the in-rip position by loosening the yoke lock handle, below the arm on the right. Then pull the yoke pivot latch forward and rotate the yoke to the in-rip position. This indexes the yoke 90" so the blade is between the motor and the column. Lock the yoke lock handle,

■ With the elevating handwheel, lower the arm until the blade just clears the table.

■ Loosen the carriage lock knob and guide the blade back to just touch the fence. Tighten the carriage lock knob,

On the right side of the arm, check the lower in-rip scale indicator, which should be set on 0 inches. If

it is not, loosen the screws and shift the indicator until it reads zero. Tighten the screws.

Loosen the yoke lock handle. Pull the yoke pivot latch forward and rotate the yoke to the out-rip position. The blade should be in front of (outside)

the motor and the column.

Lay the framing square on the table with the short edge against the fence and with the long side toward the table front.

Note the distance where the blade contacts the framing square.

On the left side of the arm on the out-rip scale, check the rip scale indicator on the rear fence

position (lower scale). The rip scale indicator should

mark the same number as the distance measured from the fence to the blade. If it does not, loosen the screws and shift the scale until the indicator is

correct. Tighten the screws.

INSTALLING CONTROL CUT DEVICE

See Figure 33.

Note: Before installing the control cut device, the yoke

assembly will travel back and forward on the carriage by pulling the handle. After installing the control cut device, the power cord for the control cut device must be plugged in and switch trigger pressed to move the yoke assembly and carriage on the arm.

WARNING: Do not install the control cut device

until after all of the initial adjustments and alignments are made to prevent accidental starting of the saw that could result in serious personal injury.

The control cut device offers many benefits. As it

increases operator control, it eliminates the risk in a cross cut of the saw “climbing” out and over the workpiece at the operator. Feed control of the blade as it cuts through the workpiece increases, as does the accuracy of the cut.

The control cut cable maintains a steady pull on the carriage assembly from the column. This tension

keeps the assembly at the column, unless you squeeze the switch trigger in the handle. The switch trigger activates the motor to counter the pull of the cable.

After a cut is completed, press the switch on the arm off, then release the switch trigger to prevent further forward motion. Hold the handle until the blade has stopped rotating. The yoke assembly will not roll forward unless you are squeezing the switch trigger.

The control cut power cord is designed to operate on a single voltage AC circuit. The speed can be set with a thumbwheel on top of the handle. The three speed settings are described on the label located on the left side of the control cut housing.

Plug in the control cut cord, leaving the main power cord disconnected. Squeeze the switch trigger to confirm the control cut motor is receiving power.

On the left side of the saw, remove the carriage lock knob and spring. Remove the two screws that attach the carriage cover and remove the cover.

Replace the spring and carriage lock knob. Pull the carriage assembly about halfway to the front. Tighten the carriage lock knob.

Squeeze the switch trigger in the handle with your right hand and pull the spring loaded cable from the column with your left hand. If you prefer to use a pair of pliers, do not damage the cable. Note: Do

not to let the spring loaded cable clamp slip out of

your hand or pliers. If it slips past the cable bracket and goes up into the control cut motor housing, then disassembly of the control cut assembly will be required to get it back out.

Place the barrel fitting into the socket at the back of the carriage assembly.

Remove the carriage lock knob and spring. Replace the carriage cover and screws, then replace the spring and carriage lock knob.

Set the speed thumbwheel, using the chart on the label. If you are unsure of the proper speed setting, use the lowest setting.

OPERATION

BASIC OPERATION OF THE RADIAL ARM SAW

A radial arm saw can be used for straight-line cutting

operations such as cross cutting, ripping, mitering, beveling, compound cutting, and resawing. It can make dado or molding cuts with special attachments.

This saw is designed to cut wood and wood composi tion products only.

The three-prong plug must be plugged into a match ing outlet that is properly installed and grounded according to all local codes and ordinances. Improper connection of the equipment can result in electric shock. Check with an electrician or service personnel if you are unsure about proper grounding. Do not modify the plug; if it will not fit the outlet, have the correct outlet installed by a qualified electrician. Refer to the Electrical page of this manual,

TYPES OF CUTS

See Figure 34.

The radial saw makes cross cuts parallel with the arm (across the grain), and rip cuts square to the arm (with the grain). Each can be made with the blade vertical or beveled. Instructions for making each kind of cut are given later in this section.

RIP CUTS

In rip cuts, the yoke is rotated 90" left or right and locked in place. The wood must ride firmly against the rip fence. There are two orientations of rip cuts - the in-rip and the out-rip. The in-rip position provides better visibility. Out-rip cuts can also be made with the blade beveled.

In an in-rip cut, the yoke is rotated to the left, which puts the blade in between the column and the motor.

The wood is fed from the right hand side.

In an out-rip cut, the blade is in front of the motor, and

the wood is fed from the left. Out-rip cutting is recom

mended only when the blade is set 12 in. or more

from the fence.

/¡L WARNING: Always make sure the blade guard

and anti-kickback pawls are in place and working

properly when making rip cuts to avoid possible injury.

A, WARNING: Always use a pushstick with small

pieces of wood, and also to finish the cut when ripping a long narrow piece of wood, to prevent

your hands from getting close to the blade.

A WARNING: All blades and cutting accessories

must be rated for at least 5,000 rpm to prevent possible injury.

CROSS CUTS

Cross cuts are made parallel to the arm. The blade is pulled along the length of the radial arm with the wood secured.

There are several types of cross cuts. A cross cut shows 0" on the miter scale (arm straight) and 0" on the bevel scale (blade straight), A miter cutis made

with the radial arm angled and the blade straight. A

bevel cut is produced with the arm straight and the blade angled.

A final type of cross cut is the compound cross cut

Both the arm and the blade are angled. Be thoroughly

familiar with making cross cuts, bevel cuts, and miter

cuts before trying a compound miter cut.

Note: In cross cuts, the blade teeth point down as

they strike the wood. In rip cuts, the teeth point up as they strike the wood.

WARNING: NEVER make a cross cut with the

short edge of the wood parallel to the fence. Kick back is likely to occur, causing the workpiece to be thrown back at you. Treat such a workpiece as a rip cut.

OPERATION

SWITCH AND SWITCH KEY

See Figures 35-37.

The main power switch has been placed on the front of the arm for easy access. The yellow switch key prevents accidental starting of the main power switch

when saw is not being used. To activate the switch,

insert the switch key and lift switch to ON position. To lock the switch once it has been pressed to OFF, remove the yellow key. Place the key in a location that is inaccessible to children and others not qualified to use the tool.

CAUSES OF KICKBACK

Kickback can occur when the blade stalls or binds, kicking the workpiece back toward you with great

force and speed. If your hands are near the blade,

they may be jerked loose and contact the blade. Obviously, kickback can cause serious injury and it is

well worth using precautions to avoid the risks.

Kickback can be caused by any action that pinches the blade in the wood, such as the following:

■ Making a cut with incorrect blade depth

■ Sawing into knots or nails in the workpiece

■ Twisting the wood while making a cut

■ Failing to support work

■ Forcing a cut

■ Cutting warped or wet lumber

■ Misusing the saw

■ Not following correct operating procedures

■ Using the wrong blade for the type of cut

■ Cutting with a dull, gummed-up, or improperly set blade,

INSERT SWITCH KEY

SWITCH ON

Fig. 35

Fig. 36

AVOIDING KICKBACK

■ Always use the correct blade depth setting. The outer point of the blade teeth should clear the lower surface of the workpiece by 1/8 in. to 1/4 in. when making these cuts.

■ Inspect the work for knots or nails before beginning a cut. Knock out any loose knots with a hammer.

Never saw into a loose knot or nail.

■ Always use the fence when rip cutting. This helps prevent twisting the wood in the cut.

■ Always use clean, sharp, and properly-set blades.

Never make cuts with dull blades.

■ To avoid pinching the blade, support the work properly before beginning a cut.

■ When making a cut, use steady, even pressure.

Never force cuts.

CRAFTSMAN’ RADIAL SAW 315.273731 42

SWITCH OFF

Fig. 37

Do not cut wet or warped lumber.

Always hold your workpiece firmly with both hands or with pushsticks. Keep your body in a balanced

position to be ready to resist kickback should it

occur. Never stand directly in line with the blade.

Use the right type of blade for the cut being made. Use the riving knife and anti-kickback pawls when

performing rip cuts.

Page 43

OPERATION

CUTTING AIDS

See Figures 38-40.

Cutting aids are used to improve the setup and help make the operator’s work safer and more accurate. They can be made from scrap wood and in various sizes and shapes for specific projects.

The basic types are pushsticks, pushblocks, and

featherboards. If the blade is set 2 in. or more from

the fence, use a pushstick. Use a pushblock when the blade is between 1/2 in. and 2 in. from the fence. (If the cut is narrower than 1/2 in., use a different saw.) Refer to the drawings and instructions provided so you can make safer and more precise cuts.

PUSHSTICKS

See Figure 38.

Pushsticks must be narrower than the workpiece, with a 90" notch in one end and shaped for a grip on the other end.

PUSHBLOCKS

See Figure 39.

A pushblock has an upright handle with a base

attached to the handle. Some pushblocks have a foot that extends down from the base and against the

workpiece. The foot is attached to the base with glue

only to prevent damage to the blade.

FEATHERBOARDS

See Figure 40.

Featherboards are used for large panels, along with an auxiliary table and a C-clamp. A featherboard has an angled end to fit against the edge of the workpiece. It is clamped in place so the workpiece moves be tween either the fence and the featherboard or the table and featherboard. Slots in the end of the

featherboard help resist kickback and allow for

variations in the width of the workpiece.

WARNING: Clamp the featherboard against the

infeed side of the workpiece. If clamped behind the blade, it could squeeze the cut edges together, causing binding and kickback. Kickback can cause serious injury.

Use this procedure to make a cut with the blade vertical and straight forward. If a kerf does not exist for the line of the cut (cutting path), follow the steps to make one. Each cutting path requires its own kerf.

WARNING: Make sure the blade guard is

lowered and is working properly to prevent possible injury. Always raise the clear plastic guard before changing the bevel or lowering the blade to avoid damage to the guard.

WARNING: Keep one hand on the handle until

the blade stops rotating to prevent the risk of injury.

■ Put the fence in the front position (next to the front table) and tighten the table clamps.

■ Check that the control cut device is set for the correct speed for the type of wood and cut you are planning. Refer to the chart on the label and adjust the thumbwheel on the handle accordingly.

■ If the yoke is not in the cross cut position with the blade parallel to the arm, release the yoke lock handle (right side, under yoke). Position the yoke correctly with the yoke pivot latch.

■ If the arm is too low or too high, first lift the blade guard if the arm is too low, and turn the elevating handwheel at the front of the table. Set the blade to just clear the kerf or table.

■ If the arm is angled, release the arm lock knob on top of the arm, position it straight ahead and lock the arm lock knob.

If the blade is angled, raise the plastic lower guard, release the bevel lock lever, and set the bevel indicator to zero. Retighten the bevel lock lever.

If the blade is in front of the fence, loosen the carnage lock knob on the left side of the arm. Release the switch trigger and let the carriage return to the back.

If there is no kerf, cut one approximately 1/16 in. deep. Grasp the handle and turn the saw on with the switch on the arm. Squeeze the switch trigger on the handle and pull the blade forward across the table to make the kerf.

Release the switch trigger and let the carriage

return to the back. Turn the saw off with the switch on the arm but hold the handle until the blade stops

rotating. Adjust the height with the elevating

handwheel so the blade will rotate freely in the kerf.

Position the workpiece against the fence. Place the

pawls and riving knife to clear the workpiece or the fence, whichever is higher, by at least 1/4 inch.

Grasp the handle with one hand. With the other, turn the saw on, then hold the workpiece down and against the fence. Keep your hand well away from the blade.

Squeeze the switch trigger on the handle and pull the blade through the workpiece but only far enough to complete the cut. Keep your hand on the

handle, even after the cut has been made and the saw turned off, until the blade stops rotating.

After completing the cut, move the workpiece to the side and turn off the saw with the switch on the arm. Release the switch trigger on the handle and

let the yoke move back behind the fence. Do not

release the handle until the blade stops rotating.

OPERATION

RIP CUT HAZARDS AND PRECAUTIONS

Two hazards are specifically associated with rip cutting: outfeed zone and wrong way feed.

In the outfeed zone (behind the blade), the blade teeth point down. The slightest contact while the blade is still spinning can snag clothing, jewelry, the work piece, or even skin, causing serious personal injury.

Wrong way feed occurs when the workpiece contacts the blade from the outfeed side. It is very hazardous and will jerk the workpiece violently. You could be cut if you are holding the workpiece.

WARNING: Failure to observe any of these

precautions can result in serious injury.

■ The first precaution is, of course, simply to stay

completely away from the outfeed zone. Keep

hands away from the outfeed zone.

■ Point the anti-kickback pawls away from the blade

teeth to snag a workpiece if the blade grabs. They should be positioned to rest lightly on the workpiece. The flat side of the pawls should be

level and horizontal,

■ Set the riving knife to just clear the table.

■ Set the hold down in front of the blade to just clear

the workpiece.

■ Start and finish your cut from the infeed side.

■ Push the workpiece past the pawls with push

blocks and pushsticks to finish the cut.

■ If the blade jams, turn the saw off with the switch

on the arm, remove the yellow key, and wait for the

blade to fully stop before freeing it.

■ Make sure the blade is parallel to the fence and the

workpiece is not warped or twisted.

■ Make sure no pressure is applied to the workpiece

on the outfeed side.

■ Make sure the blade guard is lowered and is

working properly.

■ Always set up the workpiece so the wider part of

the wood is between the blade and the fence. This stabilizes the workpiece better.

■ Do not release the workpiece until it has moved

past the pawls. Keep pushsticks firmly in place.

■ Use pushsticks and pushblocks, not your hands,

when the trailing edge of the workpiece is within

3 in. of the blade. If the blade is set 2 in. or more from the fence, use a pushstick. Use a pushblock and auxiliary fence when the blade is between 2 in. and 1/2 in. from the fence. (If the cut is narrower than 1/2 in., use a different saw.) For large panel

rip cuts, use a featherboard instead of pushblocks or pushsticks. See the section on Cutting Aids.

SETTING UP A RIP CUT

See Figure 45.

A precise and safe rip cut requires a careful set up.

Before setting up for in-rip or out-rip, especially for a bevel cut, try the workpiece in both placements. Check for stability, visibility, and control. Test which

will give the best pushstick clearance.

Instructions are given for an in-rip cut. At certain

points, the instructions will vary for a bevel rip cut or an out-rip process and will be enclosed in parenthe ses (example). Figure 40 shows an out-rip setup.

■ Insert a solid fence with no kerfs. Use an auxiliary fence if the blade will be set only 1/2 in. to 2 in. from the fence. Tighten the table clamps,

■ If the arm is too low or too high, first lift the blade guard if the arm is too low, and turn the elevating

handwheel at the front of the table. Set the blade to

just clear the kerf or table,

■ Change the blade angle if needed. Raise the plastic

lower guard to keep it from jamming, release the bevel lock lever, and set the bevel indicator to zero.

(For a bevel rip cut, set the bevel indicator to

the desired angle.) Test the clearance on the

guard. Retighten the bevel lock lever.

CRAFTSMAN’ RADIAL SAW 315.273731 48

Page 49

OPERATION

■ Put the blade in the in-rip position between the motor and the column. Release the yoke lock handle and pivot the yoke to the left, with the yoke pivot latch on the right side of the arm. (Use the

out-rip position oniy for rips 12 in. or more in width; pivot the yoke to the right so the motor is between the blade and coiumn.)

■ Loosen the carriage lock knob. Place the blade the right distance from the fence for the cut and lock the knob.

■ Cut a kerf. Turn the saw on with the switch on the arm. Lower the blade about 1/16 in. into the table to cut a shallow groove. Turn the saw off and remove the yellow key.

■ Position the workpiece against the blade, from the front of the table. Lower the hold-down in front of the blade to just clear the workpiece. (For a bevel

rip cut, place the workpiece directly under the guard rather than beside the blade.)

■ Loosen the pawls and riving knife. Lower the riving knife to the table. Slide the workpiece back and lower the pawls so that one set rests on the work piece. Lock the riving knife and pawls in place. (For

a bevel rip cut, place the workpiece under the lower set of pawls.)

■ Remove the workpiece from the table. Set the push block, featherboard, or pushstick nearby.

■ Set up table extension(s) and supports.

Keep your other hand on the table and steady the

workpiece against the fence. Keep that hand at

least 8 in. from the blade.

If the blade cover does not automatically rise as the workpiece moves from the infeed to the outfeed side, stop the cut. Turn off the saw and adjust the blade cover so it rests on the workpiece.

When the end of the workpiece is still several

inches from the blade, pick up the cutting aid you selected earlier. Push the wood with the pushstick or pushblock rather than your hand.

WARNING: Use a pushstick as the end of the

workpiece nears the blade to reduce the risk of

injury.

Push the wood completely through the blade to the outfeed, past the pawls.

When the work is completed, press the switch off and remove the key.

A WARNING: Never use a person to support

workpieces. This can cause kickback and serious injury. Never have someone stand at the outfeed side.

MAKING A RIP CUT

See Figure 46.

■ Review the Hazards and Precautions page.

■ Do not make a rip cut without following all the setup steps in the previous procedure.

■ After the saw has been set up, insert the yellow key, and turn the saw on with the switch on the arm. Let the blade build up to full speed.

■ Stand at the infeed side of the blade and out of the line of the workpiece, in case kickback occurs.

Ijk WARNING: Never stand directly in the line of

cut. Stand to the side to reduce the chance of injury should kickback occur. Start and finish the cut from the infeed side.

With the hand closest to the fence, push the workpiece under the hold down and into the blade.

When making one of the following cuts, follow the instructions that apply for the basic cut, depending on the position, shape, and size of the wood. Do not attempt these cuts until you are skilled with the basic cuts.

CUTTING LONG WORKPIECES

See Figure 47.

■ Place a support the same height as the saw table nearby for the cut work.

SUPPORT LONG WORKPIECES

WARNING: Make sure the blade guard is

lowered and is working properly to prevent possible injury.

WARNING: Never put your hands within 3 in. of

the blade when it is on.

■ Make sure the wood does not touch the blade before you turn on the saw with the switch on the

arm. Let the blade build up to full speed before it

contacts the wood.

■ When the work is completed, press the switch off

and remove the key.
