knob and tilt shoe to the desired angle by aligning the pointer with the desired angle mark.

Retighten knob firmly (clockwise).

KERF INDICATOR (FIG. 8)

The front of the saw shoe has a kerf indicator (L) for vertical and bevel cutting. This indicator

enables you to guide the saw along cutting lines penciled on the material being cut. The indicator

lines up with the left (inner) side of the saw blade, which makes the slot or "kerf" cut by the moving

blade fall to the right of the indicator. Guide along the penciled cutting line so that the kerf falls into

the waste or surplus material. Figure 8 shows the dimensions of the shoe. Note that the left side

is 5 1/2" between the left side of the blade and the left edge of the shoe (standard 6x lumber). The

right dimension is 1 1/2" (standard 2x lumber).

SHOE ALIGNMENT

Your saw has been set at the factory for accurate vertical cuts (a 90 degree angle between the

bottom of the shoe (M) and the blade). The edge of the shoe has also been set parallel to the blade

so that it will not bind when using an edge guide. If the saw should ever need adjustment, it may

be done as follows:

ADJUSTING FOR 90° CUTS (FIG. 9-11)

1. DISCONNECT PLUG FROM POWER SUPPLY.

2. Adjust the saw to 0° bevel.

3. Place saw on blade side (Figure 9). Retract blade guard.

4. Loosen quadrant knob. Place a square against the blade and shoe to adjust the 90° setting.

5. Loosen the hex nut (N) and move the adjustment screw (O) so that the shoe will stop at the

proper angle as shown in Figure 11. Lock the screw in place by tightening the hex nut.

6. It may be necessary to adjust the quadrant angle pointer to line up on "O" after shoe has

been adjusted.

ADJUSTING THE SHOE PARALLEL TO THE BLADE

1. DISCONNECT PLUG FROM POWER SUPPLY.

2. Loosen the hex nut (N) shown in Figure 10 and then turn the adjustment screw (O) in or

out as needed to adjust for parallelism.

3. Adjust the shoe until it is parallel to the blade by measuring from the edge of the shoe to the

blade, front & rear. You can measure from the outside edge of the blade to the shoe as

shown in Figure 8 or from the inner edge of the blade to the wider part of the shoe. (Do not

measure from the tips of any saw blade teeth.)

4. When the shoe and blade are parallel, hold the adjusting screw in place and tighten the hex

nut firmly.

OPERATION

Switch

Pull the trigger switch to turn the motor "ON". Releasing the trigger turns the motor "OFF".

Releasing the trigger also automatically actuates the electric brake. This tool has no provision

to lock the switch in the "ON" position, and should never be locked "ON" by any other means.

Changing Blades

CAUTION: ALWAYS TURN OFF AND DISCONNECT TOOL BEFORE CHANGING ACCES-

SORIES OR MAKING ANY ADJUSTMENTS.

TO INSTALL THE BLADE

1. Place inner clamp washer (D) on saw spindle with the large flat surface facing out toward

the blade (Fig. 2).

2. Retract the lower blade guard (C) and place blade on saw spindle against the inner clamp

washer, making sure that the blade will rotate in the proper direction (the direction of the rota-

tion arrow on the saw blade and the teeth must point in the same direction as the direction of

rotation arrow on the saw). Do not assume that the printing on the blade will always be fac-

ing you when properly installed. When retracting the lower blade guard to install the blade,

check the condition and operation of the lower blade guard to assure that it is working prop-

erly. Make sure it moves freely and does not touch the blade or any other part, in all angles

and depths of cut.

3. Place outer clamp washer (F) on saw spindle with the large flat surface against the blade and

the wording on the outer clamp washer facing you.

4. Thread blade clamping screw (G) into saw spindle by hand (screw has right-hand threads

and must be turned clockwise to tighten).

5. Depress the blade lock (B) while turning the saw spindle with the blade wrench until the

blade lock engages and the blade stops rotating (Fig. 3).

6. Tighten the blade clamping screw firmly with the blade wrench.

NOTE: Never engage the blade lock while saw is running, or engage in an effort to stop the tool.

Never turn the saw on while the blade lock is engaged. Serious damage to your saw will result.

TO REPLACE THE BLADE

1. To loosen the blade clamping screw (G), depress the blade lock (B) and turn the saw spin-

dle with the blade wrench until the blade lock engages and the blade stops rotating. With

the blade lock engaged, turn the blade clamping screw clockwise with the blade wrench

(screw has right-hand threads and must be turned counterclockwise to loosen).

2. Remove the blade clamping screw (G) and outer clamp washer ( F) only. Remove old blade.

3. Clean any sawdust that may have accumulated in the guard or clamp washer area and check

the condition and operation of the lower blade guard as previously outlined. Do not lubricate

this area.

4. Select the proper blade for the application (see Blades). Always use blades that are the cor-

rect size (diameter) with the proper size and shape center hole for mounting on the saw

spindle. Always assure that the maximum recommended speed (rpm) on the saw blade

meets or exceeds the speed (rpm) of the saw.

5. Follow steps 2 through 6 under To Install the Blade, making sure that the blade will rotate

in the proper direction.

LOWER BLADE GUARD

WARNING: The lower blade guard is a safety feature which reduces the risk of serious

personal injury. Never use the saw if the lower guard is missing, damaged, misassembled

or not working properly. Do not rely on the lower blade guard to protect you under all cir-

cumstances. Your safety depends on following all warnings and precautions as well as

proper operation of the saw. Check lower guard for proper closing before each use as

outlined in Additional Safety Rules for Circular Saws. If the lower blade guard is missing

or not working properly, have the saw serviced before using. To assure product safety

and reliability, repair, maintenance and adjustment should be performed by an author-

ized service center or other qualified service organization, always using identical

replacement parts.

Workpiece Support

Figure 12 shows proper sawing position. Note that hands are kept away from cutting area, and

power cord is positioned clear of the cutting area so that it will not get caught or hung up on the

work.

To avoid kickback, DO support board or panel NEAR the cut and on both sides of the cut,

(Figure 13). DON'T support board or panel away from the cut, (Figure 14). When ripping long

narrow strips, support cut-off waste material.

When operating the saw, keep the cord away from the cutting area and prevent it from becom-

ing hung up on the work piece. Note that a special Cord Keeper has been provided on the tool's

handle. Simply press the cord into the keeper to keep it in sight and out of the way.

WARNING: It is important to support the work properly and to hold the saw firmly to prevent

loss of control which could cause personal injury; Figure 12 illustrates typical hand support of the

saw.

ALWAYS DISCONNECT SAW BEFORE MAKING ANY ADJUSTMENTS! Place the work with its

"good" side - the one on which appearance is most important - down. The saw cuts upward, so

any splintering will be on the work face that is up when you saw it.

Support the work so that the cut will be on your right. Place the wider portion of the saw shoe

on that part of the work piece which is solidly supported, not on the section that will fall off when

the cut is made. As examples, Figure15 illustrates the RIGHT way to cut off the end of a board,

and Figure 16 the WRONG way. Always clamp work. Don't try to hold short pieces by hand!

Remember to support cantilevered and overhanging material. Use caution when sawing mate-

rial from below.

CUTTING

Be sure saw is up to full speed before blade contacts material to be cut. Starting saw with blade

against material to be cut or pushed forward into kerf can result in kickback.

Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and

toughness can vary even in the same piece of material, and knotty or damp sections can put a

heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep

it working without much decrease in speed. Forcing the saw can cause rough cuts, inaccuracy,

kickback and over-heating of the motor.

Should your cut begin to go off the line, don't try to force it back on. Release the switch and allow

blade to come to a complete stop. Then you can withdraw the saw, sight anew, and start a new

cut slightly inside the wrong one. In any event, withdraw the saw if you must shift the cut. Forcing

a correction inside the cut can stall the saw and lead to kickback. IF SAW STALLS, RELEASE

THE TRIGGER AND BACK THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT

IN THE CUT AND CLEAR OF THE CUTTING EDGE BEFORE RESTARTING.

As you finish a cut, release the trigger and allow the blade to stop before lifting the saw from the

work. As you lift the saw, the spring-tensioned telescoping guard will automatically close under

the blade. Remember the blade is exposed until this occurs, never reach under the work for any

reason whatsoever. When you have to retract the telescoping guard manually (as is necessary

for starting pocket cuts) always use the retracting lever.

NOTE: When cutting thin strips, be careful to ensure that small cutoff pieces don't hang up on

inside of lower guard.

Always use a fence or straight edge guide when ripping.

POCKET CUTTING (FIG. 17)

DISCONNECT PLUG FROM POWER SUPPLY. Adjust saw shoe so blade cuts at desired

depth. Tilt saw forward and rest front of the shoe on material to be cut. Using the retracting lever,

retract blade guard to an upward position. Lower rear of shoe until blade teeth almost touch cut-

ting line. Now release the blade guard and its contact with the work will keep it in position to

open freely as you start the cut. Start the motor and gradually lower the saw until its shoe rests

flat on the material to be cut. Advance saw along the cutting line until cut is completed. Release

trigger and allow blade to stop completely before withdrawing the blade from the material. When

starting each new cut, repeat as above. Never tie the blade guard in a raised position.

Kickback

When the saw blade becomes pinched or twisted in the cut, kickback can occur. The saw is

thrust rapidly back toward the operator. When the blade is pinched or bound tightly by the kerf

closing down, the blade stalls and the motor reaction drives the unit backward. When the blade

becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into

the top surface of the wood causing the blade to climb out of the kerf and jump back toward the

operator.

Kickback is more likely to occur when any of the following conditions exist.

1. IMPROPER WORKPIECE SUPPORT

A. Sagging or improper lifting of the cut off piece causing pinching of the blade.

B. Cutting through material supported at the outer ends only (see Figure 14). As the materi-

al weakens it sags, closing down the kerf and pinching the blade.

C. Cutting of a cantilevered or overhanging piece of material from the bottom up in a verti-

cal direction. The falling cut off piece can pinch the blade.

D. Cutting off long narrow strips (as in ripping). The cut off strip can sag or twist closing the

kerf and pinching the blade.

E. Snagging the lower guard on a surface below the material being cut momentarily reduc-

ing operator control. The saw can lift partially out of the cut increasing the chance of blade

twist.

2. IMPROPER DEPTH OF CUT SETTING ON SAW

Using the saw with an excessive depth of cut setting increases loading on the unit and sus-

ceptibility to twisting of the blade in the kerf. It also increases the surface area of the blade

avaliable for pinching under conditions of kerf close down.

3. BLADE TWISTING (MISALIGNMENT IN CUT)

A. Pushing harder to cut through a knot, a nail, or a hard grain area can cause the blade to

twist.

B. Trying to turn the saw in the cut (trying to get back on the marked line) can cause blade

twist.

C. Extended reach or operating saw with poor body control (out of balance), can result in

twisting the blade.

D. Changing hand grip or body position while cutting can result in blade twist.

E. Backing unit up to clear blade can lead to twist if not done carefully.

4. Materials that require extra attention

A. Wet lumber

B. Green lumber (material freshly cut or not kiln dried)

C. Pressure treated lumber (material treated with preservatives or anti-rot chemicals)

5. USE OF DULL OR DIRTY BLADES

Dull or dirty blades cause increased loading of the saw. To compensate, an operator will

usually push harder which further loads the unit and promotes twisting of the blade in the

kerf. Worn blades may also have reduced body clearance which increases the chance of

binding and increased loading.

6. LIFTING THE SAW WHEN MAKING BEVEL CUTS

Bevel cuts require special operator attention to proper cutting techniques - especially guid-

ance of the saw. Both blade angle to the shoe and greater blade surface in the material

increase the chance for binding and misalignment (twist) to occur.

7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED AGAINST THE MATERIAL

The saw should be brought up to full operating speed before starting a cut or restarting a

cut after the unit has been stopped with the blade in the kerf. Failure to do so can cause

stalling and kickback.

Any other conditions which could result in pinching, binding, twisting, or misalignment of the

blade could cause kickback. Refer to the sections on "Adjustments And Set-Up" and

"Operation" for procedures and techniques that will minimize the occurrence of kickback.

Blades

A dull blade will cause slow, inefficient cutting overload on the saw motor, excessive splintering

and could increase the possibility of kickback. It is a good practice to keep extra blades on hand

so that sharp blades are available while the dull ones are being sharpened (See "SAWS-

SHARPENING" in the Yellow Pages). In fact, many lower priced blades can be replaced with

new ones at very little cost over the sharpening price.

Hardened gum on the blade will slow down the cutting. This gum can best be removed with

kerosene, turpentine or oven cleaner.
