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 nameplate 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 DEWALT tools are factory tested. If this tool does not operate, check 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.

1.Using a 6 mm hex wrench, loosen rear pivot bracket fasteners (LL) just enough to allow the 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).

the right. Loosen the bevel stop screw (NN).

 

 

 

 

3.

Place a square flat against the table top and against the

 

 

 

 

blade between teeth, as shown in Figure 20. Ensure the

 

 

 

 

bevel lock lever is in its unlocked, or up, position.

Repeat at 45°, but do not adjust pointer.

 

 

 

 

MITER GAUGE ADJUSTMENT (FIG. 2)

To adjust miter gauge (J) loosen knob, set to desired angle and tighten knob.

RAIL LOCK ADJUSTMENT (FIG. 2, 17) (Tightening Fence Clamping System)

1.Lock the rail lock lever (E).

2.On the underside of the saw, loosen the jam nut (JJ).

3.Tighten the hex rod (KK) until the spring on the locking system is compressed creating the 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.

RIP SCALE ADJUSTMENT

See Adjusting the Rip Scale under Assembly.

BLADE ALIGNMENT ADJUSTMENT (FIG. 18) (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.

 

 

FENCE ALIGNMENT ADJUSTMENT (FIG. 2, 21)

 

 

(Blade Parallel to Fence)

FIG. 17

 

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:

KK

JJ

POSITION 1 FENCE ALIGNMENT (FIG. 21)

 

 

1. Install the fence in position 1 (Fig. 21) and unlock

 

 

the rail lock lever (E). Locate both locator pins (DD)

 

 

that support the fence on the front and rear rails.

 

 

2. Loosen the rear locator pin screw and adjust the

FIG. 18

 

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.
