CAUTION: To reduce the risk of personal injury, make sure table saw is firmly mounted to a
stable surface or stand provided before use.

CAUTION: Ensure that the surface is stable enough that large pieces of material will not
cause it to tip over during use.
The table saw must be mounted firmly. The mounting surface must have a 15" by 15"
(38 x 38 cm) opening to allow dust to escape.
Four holes are provided in the tool's base for mounting. We strongly recommend that these
9
holes be used to anchor the table saw to your workbench or other stationary rigid frame.
1. Center the saw on a square piece of 1/2" (12.7 mm) plywood. The plywood must have a
15" x 15" (38 x 38 cm) opening to allow dust to escape.
2. Mark the positions of the two rear mounting holes (spaced 8–5/8" [220 mm] apart) in the
frame of the saw with a pencil. Then measure forward 19–5/8" (498.5 mm) for the two
front holes spaced 9-1/16" (230 mm) apart.
3. Remove the saw and drill 5/16" (7.9 mm) holes in the places you have just marked.
4. Position the saw over the four holes you drilled in the plywood and insert four 1/4" (6.4 mm)
machine screws FROM THE BOTTOM. Install washers and 5/16" (7.9 mm) nuts on the top.
Tighten securely.
5. In order to prevent the screw heads from marring the surface to which you clamp the
saw, attach two strips of scrap wood to the bottom of the plywood base. These strips can
be attached with wood screws installed from the top side as long as they don't protrude
through the bottom of the strip.
6. Use a "C" clamp to secure the plywood base to your workbench whenever you use the saw.
Connecting Saw to Power Source

WARNING: To reduce the risk of injury, before connecting saw to power source, make
sure the switch is in the OFF position.
Be sure your power supply agrees with the name plate marking. AC Only means that this saw will
operate on alternating current only. A voltage decrease of 10 percent or more will cause a loss of
power and overheating. All D WALT tools are factory tested. If this tool does not operate, check
e
the power supply.
ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from
power source before installing and removing accessories, before adjusting or
changing set-ups or when making repairs. An accidental start-up can cause injury.
nOTE: This saw is fully and accurately adjusted at the factory at the time of manufacture. If
readjustment due to shipping and handling or any other reason is required, follow the sections
below to adjust this saw.
Once made, these adjustments should remain accurate. Take a little time now to follow these
directions carefully to maintain the accuracy of which this saw is capable.
Rail Lock Adjustment (Fig. A, O)
(Tightening Fence Clamping system)
1. Lock the rail lock lever .

2. On the underside of the saw, loosen the jam nut
3. Tighten the hex rod until the spring on the locking system is compressed creating the
37
desired tension on the rail lock lever. Retighten the jam nut against the hex rod.
4. Check that the fence does not move when the lock lever is engaged. If the fence is still loose,
tighten the spring further.

Blade Alignment Adjustment (Fig. P)
(Blade Parallel to Miter slot)

WARNING: Cut Hazard. Check the blade at 0˚ and 45˚ to make sure blade does not hit the
throat plate, causing personal injury.
If the blade appears to be out of alignment with the miter slot on the table top, it will require
calibration for alignment. To realign the blade and miter slot, use the following procedure:

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from
power source before installing and removing accessories, before adjusting or
changing set-ups or when making repairs. An accidental start-up can cause injury.
1. Using a 5 mm hex wrench, loosen rear pivot bracket fasteners
bracket to move side-to-side.
2. Adjust the bracket until the blade is parallel to the miter gauge slot.
3. Tighten the rear pivot bracket fasteners to 110–120 in-lbs (12.5–13.6 Nm).

Bevel Stop and Pointer Adjustment (Fig. Q, R)
1. Raise the blade fully by rotating the blade height adjustment wheel
it stops.
2. Unlock the bevel lock lever 7 by pushing it up and to the right. Loosen the bevel
stop screw 40 .
3. Place a square flat against the table top and against the blade between teeth, as shown
in Figure R. Ensure the bevel lock lever is in its unlocked, or up, position.
4. Using the bevel lock lever, adjust the bevel angle until it is flat against the square.
5. Tighten the bevel lock lever by pushing it down.
6. Turn the bevel stop screw 40 to rotate the bevel stop cam on the back side of the panel to
contact firmly against the stop. Continue to tighten the bevel stop screw
7. Check the bevel angle scale. If the pointer does not read 0°, loosen pointer screw
and move the pointer so it reads correctly. Retighten the pointer screw.
8. Repeat at 45°, but do not adjust pointer.

Fence Alignment Adjustment (Fig. S)
(Blade Parallel to Fence)
If you experience fence alignment problems and want to correct an out of parallel alignment
between the fence and the blade, be sure to check the alignment of the blade to the miter slot
first. After confirming that those elements are aligned, proceed with alignment of the blade to
the fence using the following procedure:
Position 1 Fence Alignment (Fig. S)
1. Install the fence in position 1 (Fig. S) and unlock the rail lock lever
pins 30 that support the fence on the front and rear rails.
2. Loosen the rear locator pin screw and adjust the allignment of the fence in the groove until
the fence face is parallel to the blade. Make sure you measure from the fence face to the front
and back of the blade to ensure alignment.
3. Tighten the locator pin screw and repeat on the left side of the blade.
4. Check rip scale pointer adjustment.
