ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
ATTACHING AND REMOVING BLADES (FIG. 2, 3)
To attach the blade, retract lower blade guard (D) using the retracting lever (C) and place inner
clamp washer (E) and blade (F) on saw spindle with teeth at bottom of blade pointing forward. Install
outer clamp washer (G). The larger surfaces of both washers must face the blade. Thread on blade
clamping screw (H) firmly by hand to hold washers in position.
Lightly depress the blade lock (I) while turning the spindle until the blade stops rotating. Tighten
blade clamping screw (clockwise) firmly with the blade wrench (Fig. 3).
NEVER ENGAGE BLADE LOCK WHILE SAW IS RUNNING, OR ENGAGE IN AN EFFORT TO
STOP THE TOOL. NEVER TURN SWITCH ON WHEN BLADE LOCK IS ENGAGED.
When removing the blade, first unplug the saw. Engage the blade lock and unscrew the blade
clamping screw by turning it counter-clockwise with the blade wrench.
CUTTING DEPTH ADJUSTMENT (FIG. 4)
Loosen (counterclockwise) the cutting depth adjustment knob (K). Lift the saw handle, as shown,
to adjust it to the desired height. Tighten the knob to secure it in place. If depth of cut cannot be
adjusted, inspect parts for damage and service as required before use. A scale and pointer are
provided to enable you to select a specific depth of cut. Simply align the pointer to the desired
depth of cut.
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 sawdust
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 material
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 (counterclockwise)
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° setting.
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 injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
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.
NOTICE: 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 specified on the rating label of the tool) 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 D WALT service center or other qualified service organization, always using
E
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
WALT certified service center.

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.
