Inspect your saw periodically for leakage. If you notice any leaks promptly return your saw to a service center for inspection and relubrication.

Brushes

CAUTION: Turn off and unplug the tool before making any adjustments or removing/installing attachments or accessories.

Inspect carbon brushes regularly by unplugging tool, removing the Brush Inspection Cover and withdrawing 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 removal. Carbon brushes have varying symbols stamped into their sides, and if either brush is worn down to the line closest to the spring, they must be replaced. Use only identical DEWALT brushes. New brush assemblies are available at your local service center. The tool should be allowed to “run in” (run at no load without a blade) for 10 minutes before use to seat new brushes.

While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON.

HOLD BY HAND ONLY.

SHOE ADJUSTMENT

CAUTION: Turn off and unplug the tool before making any adjustments or removing/installing attachments or accessories.

Your shoe has been factory set to assure that the blade is perpendicular to the shoe. If after extended use, you need to re-align the blade as follows:

ADJUSTING FOR 90 DEGREE CUTS (FIG. 7, 8)

1.Return the saw to 0 degrees bevel.

2.Place the saw on its side, and retract the lower guard.

3.Loosen the Bevel Adjustment Lever (M). Place a square against the blade and the shoe.

4.Using an Allen wrench, turn the set screw on the underside of the shoe (K) until the blade and the shoe are both in flush contact with the square. Retighten the Bevel Adjust Lever.

ADJUSTING DEPTH ADJUSTMENT AND BEVEL ADJUSTMENT LEVERS.

It may be desirable to adjust the the depth adjustment lever or the bevel adjustment lever. (They may loosen in time and hit the shoe before tightening). To tighten either, follow the steps below.

CAUTION: Turn off and unplug the tool before making any adjustments or removing/installing attachments or accessories.

1.Using a small screwdriver, pry the lock ring off, see Figure 9.

2.Remove the lever and rotate it in the desired direction about 1/8 of a revolution.

3.Reinstall the lock ring with the concave side against the lever to hold it in place.

Blades

A dull blade will cause slow, inefficient cutting, overload on the saw motor, excessive splintering and increase the possibility of kickback. Change blades when it is no longer easy to push the saw through the cut, when the motor is straining, or when excessive heat is built up in the blade. It is a good practice to keep extra blades on hand so that sharp blades are available for immediate use. Dull blades can be sharpened in most areas; see SAWS-SHARPENING in the yellow pages.

Hardened gum on the blade can be removed with trichlorethylene (nail polish remover), kerosene, turpentine, or oven cleaner. Anti-stick coated blades can be used in applications where excessive build-up is encountered, such as pressure treated and green lumber.

VISUALLY EXAMINE CARBIDE BLADES BEFORE USE. REPLACE IF DAMAGED. COMBINATION FRAMING- All purpose fast rip and cross cuts.

PRESSURE TREATED/WET LUMBER- Coated - Resistant to build-up EXTREME DURABILITY - Maximum impact resistance for longer life. FINISHING - More teeth for finer finish cuts.

FAST CUT FRAMING - Fastest blade for rips and cross cuts

DEWALT also offers a full line of steel blades for specialty jobs such as plywood, non-ferrous metal, planing, and iron/steel.

NOTE: All DEWALT blades offer a diamond knockout for use on this saw.
