BEVEL POINTER (FIG. 8)
If the bevel pointer does not indicate zero, loosen the screw that holds it in place and move it as
necessary.
FENCE ADJUSTMENT (FIG. 9)
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 48º left or right, one of the fences can be adjusted to
provide clearance. To adjust the fences, loosen a plastic knob 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 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 some 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 D
WALT service center.
E
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
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.
KERF PLATE ADJUSTMENT
To adjust the kerf plates, loosen the screws holding the kerf plates in place. Adjust so that the kerf
plates are as close as possible without interfering with the blade's movement.
RAIL GUIDE ADJUSTMENT
Periodically check the rails for any play or clearance. The right rail can be adjusted with the set
screw shown in Figure 4. To reduce clearance, use a 4 mm hex wrench and rotate the set screw
clockwise gradually while sliding the saw head back and forth. Adjust the clearance to be as small
as possible without causing any slide resistance.
MITER LOCK ADJUSTMENT
The miter lock rod should be adjusted if the table of the saw can be moved when the miter lock is
locked down. To adjust the miter lock handle, put the miter lock handle in the up, unlocked position.
Using a 13 mm open end wrench, loosen the lock nut on the miter lock rod (Fig. 10). Using a
slotted screwdriver, tighten the miter lock rod by turning it clockwise as shown in Figure 10. Turn
the lock rod until it is snug, then turn counterclockwise one turn. To ensure the miter lock handle is
functioning properly, re-lock the miter lock to a non-detented measurement on the miter scale – for
example, 34º – and ensure the table will not rotate. Tighten lock nut.
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. 4), 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 D
WALT brushes. Use of the correct grade of brush is essential for
E
proper operation of electric brake. New brush assemblies are available at D
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 OTHER WISE 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 earlier in the manual.
MITER CONTROL (FIG. 7)
The miter adjustment/lock handle and detent trigger allows you to miter your saw to 60° left and
51° right. To miter the saw, lift the miter adjustment/lock handle, push the miter latch button and
set the set the miter angle desired on the miter scale. Push down on the lock handle to lock the
saw table in place.
TRIGGER SWITCH (FIG. 4)
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.
MITER LATCH OVERRIDE (FIG. 7)
The miter latch override allows your saw to override the common stop angles. Your saw has
two miter latch override knobs, one on each side of the miter control. To override the common
stop angles, rotate the miter latch knobs downward. The knobs will return to the off position
automatically if the miter latch button is pushed.
BEVEL CONTROL (FIG. 4, 8)
The bevel latch levers and bevel lock handle allow you to bevel the saw to 48º left and right. Your
saw has two bevel latch levers, one on either side of the rear support housing. Only one needs to
be used to move the bevel to either direction. The bevel lock handle is on top of the rear support
housing. To bevel the saw, loosen the bevel lock handle. Lift one of the levers to approximately 45 º
and set the bevel angle desired on the bevel scale. Two bevel scales are provided for convenience.
Lock the bevel lock handle to lock the bevel in place. The bevel latch levers can be lifted vertically
to override the common stop angles.
The bevel lock handle is designed to have a limited rotation amount. The handle can be reoriented
to compensate for normal wear. The bevel lock handle should be reoriented if the bevel of the saw
can be moved when the bevel lock handle is tightened. To adjust the bevel lock handle, remove
the screw in the center of the handle. Carefully pry off the handle using a flat bladed screwdriver.
Reorient and install the handle such that it will hold the bevel when tightened. Install and tighten
screw.
SLIDE STOP (FIG. 10A)
The slide stop control positions your saws rails so that the largest possible verticle moldings can be
cut. ALWAYS TIGHTEN THE RAIL LOCK KNOB WHEN USING THE SLIDE STOP TO PREVENT
THE SLIDE SYSTEM FROM MOVING UNINTENTIONALLY
RAIL LOCK KNOB (FIG. 4)
The rail lock knob 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.
GROOVING STOP (FIG. 4)
The grooving stop allows for groove cutting. Flipping the lever toward the front of the saw and
adjusting the thumbscrew changes the depth of the groove cut. Flipping the lever toward the rear
of the saw bypasses the grooving stop.
HEAD DOWNLOCK PIN (FIG. 4)
To lock the saw head in the down position, push the head down, push the pin 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.
OPERATION
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.
WARNING: Always use eye protection. All users and bystanders must wear eye protection that
conforms to ANSI Z87.1 (CAN/CSA Z94.3).
Plug the saw into any household 60 Hz power source. Refer to the nameplate for voltage. Be sure
the cord will not interfere with your work.
