Operation

KERF PLATE ADJUSTMENT

To adjust the kerf plate, loosen the screws holding the plate in place. Adjust so that the kerf plate is as close to the blade as possible without interferring with the blade’s movement.

RAIL GUIDE ADJUSTMENT

Periodically check the rails for any play or clearance. The top rail can be adjusted with the two right set screws shown in figure 14. To reduce clearance, use a 4 mm hex wrench and rotate the set screws clockwise gradually while sliding the saw head back and forth. Reduce play while maintaining minimum sliding force.

Guard Actuation and Visibility

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 UNLESS THE SAW IS TURNED OFF.

NOTE: Certain special cuts will require that you manually raise the guard. See the heading “Cutting Large Material” on page 12.

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.

CAUTION: Unplug the saw before cleaning.

If the guard becomes dirty, clean with a dry cloth or a water- dampened cloth.

CAUTION: Do not use lubricants or cleaners, particularly spray or aerosal cleaners, in the vicinity of the plastic guard. The polycarbonate material used in the guard is subject to deterioration by certain chemicals.

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 DEWALT service center.

Always be sure the blade has stopped before removing it from the kerf. The brake is not a substitute for guards. Ensure your own safety by giving the saw your complete attention.

Brushes

CAUTION: Disconnect the saw from the power supply before moving it or making any adjustments.

Inspect carbon brushes regularly by unplugging tool, removing the motor end cap shown in figure 3 and with- drawing the brush assembly. Keep brushes clean and

sliding freely in their guides. Always insert a replacement brush in the same orientation in the holder as the used brush was prior to its removal. Carbon brushes have varying symbols stamped into their sides, and if the brush is worn down to the line closest to the spring, brushes must be replaced. Use only identical DEWALT brushes. Use of the correct grade of brush is essential for proper operation of electric brake. New brush assemblies are available at DEWALT service centers. 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).

CAUTION: While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON. HOLD BY HAND ONLY.

Plug the saw into 60 Hz power source. Be sure the cord will not interfere with your work.

Switch

To turn the saw on, depress the trigger switch shown in figure 15. To turn the tool off, release the switch. 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

NOTE: Although this saw will cut wood and many non-ferrous materials, we will limit our discussion to the cutting of wood only. The same guidelines apply to the other materials. DO

NOT CUT FERROUS (IRON AND STEEL) MATERIALS, MASONRY, OR FIBER CEMENT PRODUCTS WITH THIS SAW. Do not use any abrasive blades.

Crosscuts

A crosscut is made by cutting wood across the grain at any angle. A straight crosscut is made with the miter arm at the zero degree position. Set and lock the miter arm at zero, hold the wood firmly on the table and against the fence. With the rail lock knob tightened, turn on the saw by squeezing the trigger switch shown in Figure 15.

When the saw comes up to speed (about 1 second) lower the arm smoothly and slowly to cut through the wood. Let the blade come to a full stop before raising arm.

When cutting anything larger than a 2x4, use an out-down- back motion with the rail lock knob loosened. Pull the saw out, toward you, lower the saw head down toward the workpiece, and push the saw back to complete the cut. Do not allow the saw to contact the top of the workpiece while pulling out. The saw may run toward you, causing personal injury or damage to the workpiece.

NOTE: The rail lock knob shown in figure 4 must be loose to allow the saw to slide along its rails.

Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often 45 ˚ for making corners, but can be set anywhere from 50° left to 60° right. After selecting the desired miter angle, be sure to lock down the miter adjustment/lock handle. Make the cut as described above.

NOTE: 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.

BEVEL CUTS

A bevel cut is a crosscut made with the saw blade at a bevel to the wood. In order to set the bevel, unlock the bevel adjustment/lock handle and move the saw to the left or right as desired. Once the desired bevel angle has been set, lock the bevel adjustment/lock handle firmly.
