45° Bevel Override (Fig. H)
There are two 45° bevel override levers 30
or right, past 45°, push the 45° bevel override lever
the saw can bevel past these stops. When the 45° stops are needed, pull the 45° bevel override
lever forward.
Crown Bevel Pawls (Fig. I)
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 under Cutting Crown Molding). The 33.9° crown bevel
pawl 31 can be rotated to contact the crown adjustment screw
used for typical crown in North America (52/38), but can be reversed to cut non-typical (45/45)
crown. To reverse the 33.9° crown bevel pawl, remove the retaining screw
pawl and the 33.9° crown bevel pawl
32 31
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. I)
Your saw is equipped to rapidly and accurately set a 22.5° bevel, left or right. The 22.5° bevel
pawl 32 can be rotated to contact the crown adjustment screw
Rail Lock Knob (Fig. A)
The rail lock knob 22 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. J)
The depth stop 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
the depth adjustment screw 41 to set the desired depth of cut. To secure the adjustment,
tighten the wing nut 42 . 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.

Automatic Electric Blade 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 rare occasions the brake may not engage
and the blade will coast to a stop. If this occurs, wait for several minutes before continuing use.
If the condition persists, there may be a fault condition. Have the tool serviced by an authorized
D WALT service center.
e
Always be sure the blade has stopped before raising the arm and removing the blade from the
kerf plate. The brake is not a substitute for guards. Ensure your own safety by giving the saw your
complete attention.
Guard Actuation and Visibility

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 blade guard on your saw has been designed to automatically raise when the arm is brought
down and to lower over 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 BLADE GUARD MANUALLY UN LESS THE SAW IS TURNED OFF.
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.
ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn tool off and remove
the battery packs or power supply before transporting, making any adjustments,
cleaning, repairing, or removing/installing attachments or accessories. An accidental
start-up can cause injury.
Changing or Installing a New Saw Blade (Fig. A, L–N)

CAUTION:
• Never depress the spindle lock button while the blade is under power or coasting.
• Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product
with this miter saw.
• Do not use abrasive wheels or blades.
Removing the Blade (Fig. L, M)
1. Remove the battery packs or power supply.
2. Raise the arm to the upper position and raise the lower guard
3. Loosen, but do not remove guard bracket screw
far enough to access the blade screw
raised due to the position of the guard bracket screw.
4. Depress the spindle lock button
lock engages.
5. Keeping the button depressed, use the other hand and the wrench provided
the blade screw 44 . (Turn clockwise, left-hand threads.)
6. Remove the blade screw 44 , outer blade washer
washer 48 , and if used, the 1" (25.4 mm) blade adapter, may be left on the spindle.
