MITER SCALE ADJUSTMENT (FIG. 5)
Place a square against the saw's fence and blade. (Do not touch the tips of the blade teeth with
the square. To do so will cause an inaccurate measurement.) Unlock miter lock lever (J) and
swing the miter arm until the miter latch locks it at the 0 miter position. Do not lock miter lock
lever (J). If the saw blade is not exactly perpendicular to the fence, loosen the three screws that
hold the miter scale to the base and move the scale left or right until the blade is perpendicular
to the fence, as measured with the square. Retighten the three screws. Pay no attention to the
reading of the miter pointer at this time.
MITER POINTER ADJUSTMENT (FIG. 5, 6)
To unlock, lift the miter lock lever (J) up and squeeze the miter latch (K) to move the miter arm
to the zero position. With the miter lock lever unlocked allow the miter latch to snap into place
as you rotate the miter arm to zero. Observe the pointer and miter scale through the viewing
opening shown in Figure 6. If the pointer does not indicate exactly zero, loosen the screw
holding the pointer in place, reposition the pointer and tighten the screw.
BEVEL SQUARE TO TABLE (FIG. 2, 7, 8)
To align the blade square to the rotary table, lock the arm in the down position. Place a square
against the blade taking care to not have the square on top of a tooth. Loosen the bevel lock
knob (L) and ensure the arm is firmly against the 0° bevel stop. Move the 0° bevel stop adjusting
screw (O) as necessary so that the blade is at 0° bevel to the table. Ensure the bevel override
levers (N) are pushed inward to obtain an accurate adjustment.
BEVEL POINTER (FIG. 7)
If the bevel pointer (M) does not indicate zero, loosen the screw that holds it in place and move
the pointer as necessary. Do not remove the steel plate in front of the bevel pointer. This plate
prevents wood resin from accumulating on the bevel scale during use.
ADJUSTING THE BEVEL STOP TO 45 ° LEFT (FIG. 8)
NOTE: Adjust the 45 ° bevel angle only after performing the 0° bevel angle and pointer
adjustment. Ensure the 45 ° bevel override levers (N) are pushed inward to obtain an accurate
adjustment.
To adjust the left 45 ° bevel stop, first loosen the bevel lock knob (L) and tilt the head to the
left. If the pointer does not indicate exactly 45% turn the left bevel stop screw until the pointer
reads 45 °.
ADJUSTING THE BEVEL STOP TO 33.85 ° (FIG. 8)
NOTE: Adjust the 33.85 ° bevel angle only after performing the 0° bevel angle and pointer
adjustment.
To set the 33.85 ° bevel angle, flip out the stop pawl (P). Loosen the bevel lock knob (L) and tilt
the head to the left. If the pointer does not indicate exactly 33.85% turn the screw contacting the
pawl until the pointer reads 33.85 °.
FENCE ADJUSTMENT (FIG. 8)
_WARNING: To reduce the risk of serious personal injury, turn off the tool and
disconnect it from the power source before attempting to move it, change accessories
or make any adjustments accept as written in laser adjustment instructions.
In order that the saw can bevel to a full 48 ° left or right, the fences can be adjusted to provide
clearance. To adjust a fence, loosen the plastic knob (R), 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 maximum workpiece support, without interfering with arm up and
down movement. Tighten knob securely. When the bevel operations are complete, don't forget
to relocate the fence.
NOTE: The guide groove of the fences can become clogged with sawdust. If you notice that it is
becoming clogged, use a stick or low pressure air to clear the guide groove.
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.
GUARD ACTUATION AND VISIBILITY
ACAUTION: 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 orfor inspection of the
saw. NEVER RAISE THE BLADE GUARD MANUALLY UNLESS THE SAW IS TURNED OFR
NOTE: Certain special cuts of large material will require that you manually raise the guard.
The front section of the guard is Iouvered 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. Refer to Cutting Large Material under
Special Cuts.
MITER LOCK ADJUSTMENT (FIG. 10)
The miter lock rod should be adjusted if the table of the saw can be moved when the miter
lock handle is locked down. To adjust, put the miter lock handle in the 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 miter lock handle to a non-detent
miter angle.
Brushes
WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect
it from the power source before attempting to move it, change accessories or make any
adjustments accept as written in laser adjustment instructions.
Inspect carbon brushes regularly by unplugging tool, removing the motor end cap (Fig. 2), lift
the brush spring and withdraw the brush assembly. Keep brushes clean and sliding freely in
their guides. Always replace a used brush in the same orientation in the holder as it was prior
to its removal. Carbon brushes have varying symbols stamped into their sides, and if the brush
is worn down to approximately 1/2" (12.7 mm), the spring will no longer exert pressure and they
must be replaced. Use only identical DEWALT brushes. Use of the correct grade of brush is
essential for proper operation of electric brake. New brush assemblies are available at DEWALT
service centers. The tool should be allowed to "run in" (run at no load) for 10 minutes before
use to seat new brushes. The electric brake may be erratic in operation until the brushes are
properly seated (worn in). Always replace the brush inspection cap after inspection or servicing
the brushes.
While "running in" DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON.
HOLD BY HAND ONLY.
Controls
Your compound miter saw has several main controls, which will be discussed briefly here. For
more information on these controls, see the respective sections later in the manual.
MITER CONTROL (FIG. 5, 9)
The miter lock/adjustment lever and trigger allows you to miter your saw 50 ° left and right. To
miter the saw, unlock miter lock lever (J) by pulling upward, squeeze the detent trigger (K) and
set the miter angle desired on the miter scale. Lock miter lock handle by pressing downward.
Override the detent trigger by rotating knob (Fig. 9, V).
TRIGGER SWITCH (FIG. 2)
The trigger switch turns your saw on and off. A hole is provided in the trigger for insertion of a
padlock to secure the saw.
BEVEL LOCK (FIG. 7, 8)
The bevel lock knob (L) allows you to bevel the saw 48 ° left or right. To loosen the handle and
adjust the bevel setting, turn the handle counterclockwise, the saw head bevels easily to the
left. To tighten, turn the handle clockwise. Bevel degree markings are on the bottom front of the
saw arm (Fig. 7, M).
0°/45 ° BEVEL STOP OVERRIDES (FIG. 8)
The bevel stop overrides (N) are held secure with their attachment screw to prevent inadvertent
movement. Use the bit on the blade wrench to loosen the attachment screw. This allows the
slides, to be pulled outward and the saw head to pivot past the 0°/45 ° mark. Be sure to retighten
the attachment screw when finished.
33.85 ° BEVEL STOPS (FIG. 8)
The pawl (P) is used to stop the saw head bevel setting at 33.85 °. This setting is used primarily
for cutting crown moldings laid flat on the table.
HEAD DOWNLOCK PIN (FIG. 8)
To lock the saw head in the down position, push the head down, push the pin (U) 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 and pull the pin out.
