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 13mm 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 meas-
urement on the miter scale – for example, 34 degrees –
and ensure the table will not rotate. Tighten lock nut.

Brushes

DISCONNECT PLUG FROM POWER SUPPLY.
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 inch, the spring will no longer exert pres-
sure and they must be replaced. Use only identical
D WALT brushes. Use of the correct grade of brush is
E
essential for proper operation of electric brake. New brush
assemblies are available at D WALT service centers. The
E
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 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 50 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
The trigger switch (Fig. 4) 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. To override the common stop
angles, push the miter latch button and flip the miter latch
override lever to the vertical position.
BEVEL CONTROL (FIG. 8)
The bevel latch levers and bevel lock handle allow you to
bevel the saw to 48 degrees left and right. Your saw has
two bevel latch levers, one on either side of the rear sup-
port 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
degrees 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 rota-
tion amount. The handle can be reoriented to compensate
for normal wear. The bevel lock handle should be reorient-
ed 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 tight-
ened. Install and tighten screw.
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 thumb-
screw 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

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.

SWITCH

To turn the saw on, depress the trigger switch. To turn the
tool off, release the switch. Allow the blade to spin up to full
operating rpm before making the cut. Release the trigger
switch and allow the brake to stop the blade before raising
the saw head. There is no provision for locking the switch
on, but a hole is provided in the trigger for insertion of a
padlock to lock the saw off.

CUTTING WITH YOUR SAW

If the slide feature is not used, ensure the saw head is
pushed back as far as possible and the rail lock knob is
tightened. This will prevent the saw from sliding along its
rails as the workpiece is engaged.
NOTE: Although this saw will cut wood and many non-
ferrous materials, we will limit our discussion to the cut-
ting of wood only. The same guidelines apply to the
other materials. DO NOT CUT FERROUS (IRON AND
STEEL) MATERIALS OR MASONRY WITH THIS SAW.
Do not use any abrasive blades.

CROSSCUTS

Cutting of multiple pieces is not recommended but can be
done safely by ensuring that each piece is held firmly
against the table and fence. When the saw comes up to
speed (about 1 second) lower the arm smoothly and slow-
ly to cut through the wood. Let the blade come to a full stop
before raising arm.
