Safety Instructions

WARNING: Do not connect unit to electrical power source until complete instructions are read and understood.

WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) standards. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

WARNING: NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE FENCE.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).

To reduce your exposure, wear approved safety equipment, such as those masks that are specifically designed to filter out microscopic particles.

WARNING: When operating this tool, always observe these safety rules:

• Avoid accidental contact with the saw.
• Wear appropriate clothing and wash exposed areas with soap and water.
• Disconnect the power supply before servicing.

Electrical Connection

Be sure your power supply agrees with the nameplate marking, 120 volts AC, means that your saw will operate on alternating current. The switch is susceptible to failure if direct current is used. 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.

Important Safety Instructions

Changing or Installing a New Saw Blade

1. Unplug the saw.
2. Raise the saw to the upper position and raise the blade guard as far as possible.
3. Loosen, but do not remove guard bracket screw.
4. Depress the spindle lock while carefully rotating the saw blade by hand until the lock engages.
5. Remove the blade screw.
6. Install the new blade following the reverse procedure.

NOTE: For blades with a blade hole of 5/8” (15.88 mm), use (1) 1” (25.4 mm) blade adapter if not used.

Adjustments

Miter Scale Adjustment Place a square against the saw’s fence and blade.

Bevel Square to Table Adjustment Align the blade square to the table, and check the alignment.

Transporting the Saw

WARNING:

• Always unplug the tool before transporting.
• Use the carrying handles for safer transport.

OPERATION

WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect it from the power source before attempting to move it, change accessories or make any adjustments except as written in laser adjustment instructions.

USER MANUAL

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.

TO SWITCH

To turn the saw on, depress the trigger switch. To turn off, release the switch. Allow the blade to come to a full stop before placing the tool down.

SETTING UP YOUR SAW

If the slide feature is not used, ensure the saw head is pushed back as far as possible and the lock knob is tightened. This will prevent the saw from sliding as it raises the workpiece to the saw.

CROSSCUTS

Cutting off mobile pieces is not recommended as doing so will ensure that each piece is held firmly against the table and fence.

Ensure material does not creep while cutting, clamp it securely in place.

If small fibers of wood still split out at the rear of the workspace, stick a piece of masking tape on the wood where the cut will be made.

QUALITY OF CUT

The quality of the cut can depend on various factors including blade material, setup, and how the saw is used.

BLADE INSTALLATION

1. Install the blade behind the fence. The clamp should be facing toward the back of the saw.
2. Rotate the clamp “180” toward the front of the miter saw.
3. Loosen the knob to slide the blade assembly back and forth.

CLAMPING

While making a cut, clamp the workpiece and ensure it does not move.

SAW BLADES

For the best cutting capabilities, refer to the list of recommended saw blades for your saw and select one that fits your needs.

CUTTING PICTURE FRAMES, SHADOW BOXES AND OTHER FOUR-SIDED PROJECTS

Your saw is perfect for cutting bevels and miters.

CUTTING CROWN MOLDING

To cut molding, adjust the miter angle and use appropriate settings.

IMPORTANT

1. Follow the provided instructions closely.
2. Ensure all settings are right before making cuts.

PRESETTING WITH SCRAP MATERIAL

Always make cuts from a scrap piece before moving on to the final piece.

BEVEL SETTING

TYPE OF CUT

• RIGHT SIDE, INSIDE CORNER
  1. Top of molding against fence.
  2. Saw blade set at 31.62°
• LEFT SIDE, OUTSIDE CORNER
  1. Top of molding against fence.
  2. Saw blade set at 31.62°
• LEFT SIDE, INSIDE CORNER
  1. Top of molding against fence.
  2. Saw blade set at 31.62°
• RIGHT SIDE, OUTSIDE CORNER
  1. Top of molding against fence.
  2. Saw blade set at 31.62°

When setting bevel and miter angles for corners, remember that: The angles presented for crown molding are very precise and difficult to set exactly. Since they can easily shift and only moldings have nearly square corners, all settings should be tested on scrap molding.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT

ALTERNATIVE METHOD FOR CUTTING CROWN MOLDING

Place the molding on the table at an angle between the fence and the saw table, as shown in Figure 18. Use of the crown molding needle accessory (DW7048) is highly recommended for aiming and ensures precision and convenience. The crown molding fence accessory is available for purchase from your local dealer.

The advantage to cutting crown molding using this method is that no bevel cut is required. Minute changes in the angle can be made while affecting the bevel angles. Thus, when corners other than 90° are encountered, the saw can be quickly and easily adjusted for them. Use the crown molding knife accessory to maintain the cut angle at which the molding will rest on the wall.

SPECIAL CUTS

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE FENCE.

ALUMINUM CUTTING

ALWAYS USE THE APPROPRIATE SAW BLADE ESPECIALLY FOR CUTTING ALUMINUM. These are available at your local DEWALT retailer or DEWALT service center. For your convenience, use this chart to select the correct type of a cutting blade for different jobs.

1. Make a platform using a piece of 1.5” (38 mm) thick plywood or similar flat stock of a length 14.5” x 26” (368 x 660 mm). The platform must first be secured to the table surface during cutting and cause injury.
2. Mount the 14.5” x 26” (368 x 660 mm) platform to the saw using four 3” (76.2 mm) long flat wood screws through the holes in the base plate (Fig. 19).

CUTTING PLASTIC PIPE OR OTHER ROUND MATERIAL

Plastic pipe can be safely cut with your saw. It should be cut just like wood and CLAMPED OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important when making end cuts.

OUTING LARGE MATERIAL

If this occurs, simply realign your work on the table beneath the blade guard.

1. If your compound is that heavy, as shown in Figure 20.
2. Always adjust it as much as is necessary.

SAFETY SET UP FOR HEDGE CROSSES

You can set your width to 1/6” (406 mm) whenever a special setup is used to mount the saw up for fence workpieces, following these steps:

1. Remove both left and right sliding fences from the saw and set aside.
2. Make the necessary adjustments and reattach the fences and clean the fence outward. Adjust and reposition to confirm smooth cuts later.

MAINTENANCE

• DO NOT USE lubricants or cleaners (particularly spray or aerosol) on the cutting edge.
• All bearings are sealed. They are lubricated for life and need no further maintenance.
• Regularly clean the blade and base to ensure optimal performance.
