that conforms to ANSI Z87.1 (CAN/CSA Z94.3).
WARNING: To ensure the blade path is clear of obstructions, always make a dry run of the
cut without power before making any cuts on theworkpiece.
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off, and remove
the battery pack before transporting, making any adjustments, cleaning,
repairing, or removing/installing attachments or accessories. An accidental
start‑up can causeinjury.
the saw can bevel past these stops. When the 45° stops are needed, pull the 45° bevel
override leverforward.
Crown Bevel Pawls (Fig. J)
When cutting crown molding laying flat, your saw is equipped to accurately and rapidly set
a crown stop, left or right (refer to Instructions for Cutting Crown Molding Laying Flat
and Using the Compound Features). The crown bevel pawl
51
can be rotated to contact
the crown adjustment screw
46
. The saw is factory set to be used for typical crown in North
America (52/38), but can be reversed to cut non‑typical (45/45) crown. To reverse the crown
bevel pawl, remove the retaining screw, the 22.5° bevel pawl and the 33.9° crown bevel pawl.
Flip the crown bevel pawl so the 30° is facing up. Reattach the screw to secure the 22.5°
bevel pawl and the crown bevel pawl. The accuracy setting will not beaffected.
22.5 ° Bevel Pawls (Fig. J)
Your saw is equipped to rapidly and accurately set a 22.5° bevel, left or right. The 22.5° bevel
pawl
47
can be rotated to contact the crown adjustmentscrew.
Rail Lock Knob (Fig. A)
The rail lock knob
30
allows you to lock the saw head firmly to keep it from sliding on the rails.
This is necessary when making certain cuts or when transporting thesaw.
Depth Stop (Fig. A)
The depth stop
25
allows the depth of cut of the blade to be limited. The stop is useful for
applications such as grooving and tall vertical cuts. Rotate the depth stop forward and adjust
the depth adjustment screw
29
to set the desired depth of cut. To secure the adjustment,
tighten the wing nut
22
. Rotating the depth stop to the rear of the saw will bypass the depth
stop feature. If the depth adjustment screw is too tight to loosen by hand, the provided blade
wrench can be used to loosen thescrew.
Slide Lock Transport Lever (Fig. L1–L3)
Slide Lock Position (Fig.L1)
The slide lock transport lever
61
in forward location locks saw for maximize vertical
cuttingcapacity.
Transport Position (Fig.L2)
The slide lock transport lever
61
in rear location locks saw in the transport position to secure
the saw head during transport and storage. Recommended for relocating or carrying thesaw.
Stow Position (Fig.L3)
When not in use, the slide lock transport lever
61
can be placed in a stow position. The slide
lock lever locks in place using an indent on the back of the lever that slides up the ramp and
falls into the cast pocket
64
. To unlock the lever, slightly pull the lever till it clears out of the
cast pocket and rotateclockwise.
Automatic Electric Brake
Your saw is equipped with an automatic electric blade brake which stops the saw blade within
5seconds of trigger release. This is notadjustable.
On occasion, there may be a delay after trigger release to brake engagement. On rare
occasions, the brake may not engage at all and the blade will coast to astop.
If a delay or “skipping” occurs, turn the saw on and off 4or 5times. If the condition persists,
have the tool serviced by an authorized DEWALT servicecenter.
Always be sure the blade has stopped before removing it from the kerf. The brake is
not a substitute for guards or for ensuring your own safety by giving the saw your
completeattention.
FEATURES AND CONTROLS
WARNING: To reduce the risk of serious personal injury, turn tool off, and remove
the battery pack before transporting, making any adjustments, cleaning,

16
before transportingsaw.
In order to conveniently carry the miter saw from place to place, a lifting handle
15
has been
included on the top of the saw arm and hand indentations
11
in thebase.
Head Lock Knob (Fig. A)
WARNING: The head lock knob should be used ONLY when carrying or storing the
saw. NEVER use the headlock knob for any cuttingoperation.
To lock the saw head in the down position, push the head down, rotate head lock knob
19
90° and the spring loaded pin will lock in and release the saw head. This will hold the saw
head safely down for moving the saw from place toplace.
To release, press the saw head down, pull out the head lock knob and rotate 90°.
Miter Lock Adjustment (Fig. A, K)
The miter lock rod
48
should be adjusted if the table of the saw can be moved when the
miter lock handle
7
is locked (down). To adjust the miter lock
49
, put the miter lock handle
in the unlocked (up) position. Using a slotted screwdriver, adjust the lock rod in 1/8 clockwise
turn increments to increase the lock force. To ensure the miter lock is functioning properly,
re‑lock the miter lock handle to a non‑detent miter angle – for example , 34° ‑ and make sure
the table will notrotate.
Rail Guide Adjustment (Fig. A, F)
Periodically check the rails
24
for any play or clearance. The right rail can be adjusted with the
rail set screw
33
shown in FigureF. To reduce clearance, use a 4 mm hex wrench and rotate
the rail set screw clockwise gradually while sliding the saw head back and forth. Reduce play
while maintaining minimum slideforce.
Guard Actuation and Visibility (Fig. A, Z)
CAUTION: Pinch Hazard. To reduce the risk of injury, keep thumb underneath the handle
when pulling the handle down. The lower guard will move up as the handle is pulled
down which could causepinching.
The lower guard
6
on your saw has been designed to automatically uncover the blade when
the arm is brought down and to cover the blade when the arm israised.
The guard can be raised by hand when installing or removing saw blades or for inspection of
the saw. NEVER RAISE THE LOWER GUARD MANUALLY UN LESS THE BLADE ISSTOPPED.
NOTE: Certain special cuts of large material will require that you manually raise the guard.
Refer to Cutting Large Material under SpecialCuts.
The front section of the guard is louvered for visibility while cutting. Although the louvers
dramatically reduce flying debris, they are openings in the guard and safety glasses should be
worn at all times when viewing through thelouvers.
Fence Adjustment (Fig. A)
In order that the saw can bevel to many bevel positions, one of the fences may have to be
adjusted to provide clearance. To adjust each fence, loosen the fence adjustment knob
16
and slide the fence outward. Make a dry run with the saw turned off and check for clearance.
Adjust the fence to be as close to the blade as practical to provide max imum workpiece
support, without interfering with arm up and down movement. Tighten the fence adjustment
knob securely. When the bevel operations are complete, don’t forget to relocate thefence.
For certain cuts, it may be desirable to bring the fences closer to the blade. To use this feature,
back the fence adjustment knobs out two turns and move the fences closer to the blade past
the normal limit, then tighten the fence adjustment knobs to keep the fences in this location.
When using this feature, make a dry cut first to ensure the blade does not contact thefences.
NOTE: The tracks of the fences can become clogged with sawdust. If you notice that they are
becoming clogged, use a brush or some low pressure air to clear the guidegrooves.
Bevel Lock Knob (Fig. A)
The bevel lock knob
13
allows you to bevel the saw 49° left or right. To adjust the bevel
setting, turn the knob counterclockwise. The saw head bevels easily to the left or to the right
once the 0° bevel stop
28
is in the 0° bevel override position. To tighten, turn the bevel lock
knobclockwise.
0 ° Bevel Override (Fig. A)
The bevel stop override allows you to bevel the saw to the right past the 0°mark.
When engaged, the saw will automatically stop at 0° when brought up from the left.
To move past 0° to the right, pull the 0° bevel stop
28
, rotate 90° (either clockwise or
counterclockwise) and let go for the spring loaded pin to lock in.
To return the bevel to 0° bevel stop, pull the 0° bevel stop, rotate 90° (either clockwise or
counterclockwise) and let go for the spring loaded pin will lockin.
45 ° Bevel Stop Override (Fig. J)
There are two bevel stop override levers
50
, one on each side of the saw. To bevel the saw, left
or right, past 45°, push the 45° bevel override lever rearward. When in the rearward position,
