and adjust to the zero indicator mark. The saw is now adjusted to accurately indicate the depth

of cut for the blade used.

For the most efficient cutting action using a carbide tipped saw blade, set the depth adjustment

so that about one half of a tooth projects below the surface of the wood to be cut. The height

of a whole tooth is the distance from the tip of the tooth to the bottom of the gullet in front of it.

Study Figures 5A and 5B to determine what one half tooth means. (Figure 5A shows one half

tooth projecting below the surface and Figure 5B shows a whole tooth projecting below the

surface.)

Setting the saw at the proper cutting depth keeps blade friction to a minimum, removes saw-

dust from between the blade teeth, results in cooler, faster sawing and reduces the chance of

kickback.

A method of checking for the correct cutting depth is shown in Figure 6. Lay a piece of the mate-

rial you plan to cut along the side of the blade, as shown in the figure, and observe how much

tooth projects beyond the material.

NOTE: When using a non carbide tipped blade, make an exception to the above procedure and

allow a full tooth to project below the material, as shown in Figure 5B.

BEVEL ANGLE ADJUSTMENT (FIG. 7)

The full range of the Bevel Adjustment is from 0 to 50 DEGREES. The quadrant (L) is graduated

in increments of 1 degree.

On the front of the saw is a bevel angle adjustment mechanism consisting of a calibrated

quadrant (L) and a bevel adjustment knob (M). To set the saw for a bevel cut, loosen (counter-

clockwise) the quadrant 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 (N) 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" (140mm) between the left side of the blade and the left edge of the shoe (standard 6x

lumber). The right dimension is 1-1/2" (38mm) (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 (J) and the blade (F). 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 (Fig. 9). Retract blade guard.

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

ting.

5. Loosen the hex nut (O) and move the adjustment screw (P) 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 “0” after shoe has

been adjusted.

ADJUSTING THE SHOE PARALLEL TO THE BLADE

1. DISCONNECT PLUG FROM POWER SUPPLY.

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

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect

tool from power source before making any adjustments or removing/installing attach-

ments or accessories.

Switch

Pull the trigger switch (B) 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

WARNING: Avoid contact with the blade teeth to prevent personal injury.

CAUTION: 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 INSTALL THE BLADE

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

the blade (Fig. 2).

2. Using the lever (C), retract the lower blade guard (D) 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 rotation 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 facing 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 properly. 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 (G) 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 (H) into saw spindle by hand (screw has right-hand threads

and must be turned clockwise to tighten).

5. Depress the blade lock (I) 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 (H), depress the blade lock (I) and turn the saw spindle

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

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

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

2. Remove the blade clamping screw (H) and outer clamp washer (G) 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

correct 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

circumstances. 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

authorized

DEWALT service center or other qualified service organization, always using

identical replacement parts.

Workpiece Support

WARNING: Hands should be kept away from cutting area to reduce the risk of injury.

WARNING: The power cord should be positioned clear of the cutting area so that it will not

get caught or hung up on the work and to prevent electric shock.

WARNING: When operating the saw, keep the cord away from the cutting area to prevent

electric shock.

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 17 illustrates typical hand support of

the saw.

Figure 12 and 13 show proper sawing position. Figure 14 and 16 show an unsafe condition.

To avoid kickback, DO support board or panel NEAR the cut (

Fig. 14 ). DON’T support board or

panel away from the cut (

Fig. 14, 16).

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, Figure 15 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

material 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)

WARNING: Use the lever (C) provided on the lower guard when you have to retract the guard

manually.

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 cutting 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
