  1. To run the tool, press the on/off switch  1 .
  2. To stop the tool, release the switch.

Use of XPS™ LED Worklight System (Fig. A, V)NOTE: The mitre saw must be connected to a power source.The XPS™ LED Worklight System is operated with an push button switch, fitted on the handle under the black plastic lever. The XPS™ LED Worklight System is independent of the mitre saw’s trigger switch.To cut through an existing pencil line on a piece of wood:

  1. Push the black plastic lever, then pull down on the operating handle  3 to bring the saw blade  8 close to the wood. The shadow of the blade will appear on the wood.
  2. Align the pencil line with the edge of the blade’s shadow. You may have to adjust the mitre or bevel angles in order to match the pencil line exactly.

Speed Control Dial (DWS771 only)The speed control dial  29 can be used for advance setting of the required range of speed. Turn the speed control dial  29 to the desired range, which is indicated by a number (1–5).

  •  Use high speeds for sawing soft materials such as wood.
  • Use low speeds for sawing hardwood.

Body and Hand PositionProper positioning of your body and hands when operating the mitre saw will make cutting easier, more accurate and safer.


  • Never place your hands near the cutting area.
  • Place your hands no closer than 150 mm from the blade.
  • Hold the workpiece tightly to the table and the fence when cutting. Keep your hands in position until the switch has been released and the blade has completely stopped.
  • Always make dry runs (without power) before finish cuts so that you can check the path of the blade.
  •  Do not cross your hands.
  • Keep both feet firmly on the floor and maintain proper balance.
  • As you move the saw arm left and right, follow it and stand slightly to the side of the saw blade.

Basic Saw CutsVertical straight cross cut (Fig. A, S)NOTE: Use 216 mm saw blades with 30 mm arbor holes to obtain the desired cutting capacities.

  1. Slacken the mitre latch  13 and subsequently lift it up.
  2. Engage the mitre latch  13 at the 0° position and fasten the mitre latch.
  3. Place the wood to be cut against the fence  16 .
  4. Take hold of the carrying handle  3 and press the guard lock up release lever  2 to release the guard. Press the trigger switch  1 to start the motor. It is recommended to start the cut near the fence.
  5.  Depress the head to allow the blade to cut through the timber and enter the plastickerf plate  11 .
  6. When the head is fully depressed, slowly pull it across to complete the cut.
  7. After completing the cut, release the switch and wait for the saw blade to come to a complete standstill before returning the head to its upper rest position.


  • For some types of plastic profiles, it is advisable to follow the sequence in reverse order.
  • The lower blade guard is designed to close quickly when the lever  2 is released. If it does not close within 1 second, have the saw serviced by an authorized DEWALT repair agent.

Vertical mitre cross-cut (Fig. A, T)

  1. Squeeze the mitre latch  13 . Move the arm left or right to the required angle.
  2. The mitre latch will automatically locate at 0°, 15°, 22.5°, 31.62°, 45° and 50° both left and right. If any intermediate angle is required hold the head firmly and lock by fastening the mitre latch.
  3. Always ensure that the mitre lock lever is locked tightly before cutting.
  4.  Proceed as for a vertical straight cross-cut.

WARNING: When mitring the end of a piece of woodwith a small off-cut, position the wood to ensure that the off-cut is to the side of the blade with the greater angle to the fence, i.e.:

  • left mitre, off-cut to the right
  • right mitre, off-cut to the left

Bevel cross-cuts (Fig. P, U)Bevel angles can be set from 0° to 48° to the left. Bevels up to 45° can be cut with the mitre arm set between zero and a maximum of 45° mitre position right or left.

  1. Loosen the bevel clamp handle  20 and set the bevel as desired.
  2. Set the override button  31 if required.
  3.  Hold the head firmly and do not allow it to fall.
  4. Tighten the bevel clamp handle  20  firmly.
  5.  Proceed as for a vertical straight cross-cut.

Quality of CutThe smoothness of any cut depends on a number of variables, i.e. the material being cut. When smoothest cuts are desired for moulding andother precision work, a sharp (60-tooth carbide) blade and a slower, even cutting rate will produce the desired results.

WARNING: Ensure that the material does not creep while cutting; clamp it securely in place. Always let the blade come to a full stop before raising the arm. If small fibres of wood still split out at the rear of the workpiece, stick a piece of masking tape on the wood where the cut will be made. Saw through the tape and carefully remove tape when finished.

Clamping the Workpiece (Fig. C, X)WARNING: Always use a material clamp.For best results use the material clamp  17 made for use with your saw. To Install clamp

  1. Insert it into the hole behind the fence. The clamp  17 should be facing toward the back of the mitre saw. Ensure the groove on the clamp rod is fully inserted into the base of the mitre saw. If the groove is visible, the clamp will not be secure.
  2. Rotate the clamp 180º toward the front of the mitre saw.
  3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly clamp the workpiece.


Compound Mitre (Fig. W)

This cut is a combination of a mitre and a bevel cut. This is the type of cut used to make frames or boxes with slanting sides like the one shown in figure W.WARNING: If the cutting angle varies from cut to cut, check that the bevel clamp handle and the mitre clamping knob are securely tightened. These must be tightened after making any changes in bevel or mitre.

  • The chart shown below will assist you in selecting the proper bevel and mitre settings for common compound mitre cuts.
  • To use the chart, select the desired angle “A” (Fig. W) of your project and locate that angle on the appropriate arc in the chart. From that point follow the chart straight down to find the correct bevel angle and straight across to find the correct mitre angle.

  1. Set your saw to the prescribed angles and make a few trial cuts.
  2.  Practice fitting the cut pieces together.Example: To make a four-sided box with 25° exterior angles (angle “A”) (Fig. W), use the upper right arc. Find 25° on the arc scale. Follow the horizontal intersecting line to either side to get the mitre angle setting on the saw (23°). Likewise follow the vertical intersecting line to the top or bottom to get the bevel angle setting on the saw (40°).

Always try cuts on a few scrap pieces of wood to verify the settings on the saw.WARNING: Never exceed the compound mitre limits of 45° bevel with 45° left or right mitre.

Support for Short and Long Pieces (Fig. C, D)Cutting Short MaterialIt is advisable to use the length stop  41 for short workpieces both for batch sawing and for short individual workpieces of different lengths. The length stop can only be used in conjunction with a pair of optional guide rails  35 .

Cutting Large MaterialWARNING: To reduce the risk of injury, always support long workpieces.Figure C shows the ideal configuration for sawing long workpieces when the saw is used free-standing (all items available as an option).These items (except the legstand and the material clamp) are required both on the infeed and the outfeed side:

  • Legstand  40 (supplied with mounting instructions).
  • Guide rails (500 or 1,000 mm)  35 .
  • Stands  39 to support the guide rails. Do not use the stands to support the machine! The height of the stands is adjustable.
  • Material support plates  36 .
  • Table end plate  34 for supporting the rails (also when working on an existing bench).
  • Material clamp  17 .
  • Swivelling stop  38 .
  1. Place your saw on the legstand and fit the guide rails.
  2.  Firmly screw the material support plates  36 to the guide rails  35 .
  3. The material clamp  17 now functions as a length stop.
  4. Install the table end plates  34 .
  5.  Install the swivelling stop  38 to the rear rail.
  6. Use the swivelling stop  38 to adjust the length of medium and long workpieces. It can be adjusted sideways or swung out of the way when not in use.
