INTENDED USE
Your DW717 mitre saw has been designed for professional cutting of wood, wood products, aluminium and plastics. It will perform the sawing operations of cross-cutting, bevelling and mitring easily, accurately and safely.
The DW717 mitre saw is a professional power tool. DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool.

Electrical safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.
Your tool is double insulated in accordance with EN 61029; therefore no earth wire is required.
In case of cord replacement the tool must only be repaired by an authorized service agent or by qualifi ed electrician.

Mains plug replacement (U.K. & Ireland only)

• Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an authorized DEWALT repair agent or a qualifi ed electrician.
• Disconnect the plug from the supply.
• Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.
• Only fi t 13 Amperes BS1363A approved plugs fi tted with the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for Live (L) (2) and Blue is for Neutral (N) (4).
• Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable fi rmly and that the two leads are correctly fi xed at the terminal screws.

Never use a light socket.
Never connect the live (L) or neutral (N) wires to the earth pin marked E or .

Fitting a mains plug to 115 V units (U.K. & Ireland only)

• The plug should be fi tted by a competent person. If you are in doubt, contact an authorized DEWALT repair agent or a qualifi ed electrician.
  The wires are coloured according to the following code:
  live = brown
  neutral = blue
• Do not connect the blue or brown wire to the earth terminal in the plug.
  Connect as follows:
  brown to terminal marked 'L'
  blue to terminal marked 'N'

The plug fitted should comply with BS EN 60309 (BS4343), 32 Amps.
Always ensure that the cable clamp is correctly and securely fi tted to the sheath of the cable.

Using an extension cable
If an extension cable is required, use an approved extension cable suitable for the power input of this tool (see technical data).
The minimum conductor size is 1.5 mm².
When using a cable reel, always unwind the cable completely. Also refer to the table below.

Voltage drops
Inrush currents cause short-time voltage drops. Under unfavourable power supply conditions, other equipment may be affected. If the system impedance of the power supply is lower than 0.25 Ω, disturbances are unlikely to occur.

ASSEMBLY

To reduce the risk of injury, turn off tool and disconnect from power source before attempting to move it, changing accessories or making any adjustments accept as written in laser adjustment instructions.

Unpacking (fig. A1, B)

• Remove the saw from the packing material carefully using the carrying handle (10).
• Release the rail lock knob (16), and push the saw head back to lock it in the rear position.
• Press down the operating handle (11) and pull out the lock down pin (22), as shown.
• Gently release the downward pressure and allow the arm to rise to its full height.

Bench mounting (fig. C)

• Holes (25) are provided in all four feet to facilitate bench mounting. Two different sized holes are provided to accommodate different sizes of bolts. Use either hole; it is not necessary to use both. Always mount your saw fi rmly to prevent movement. To enhance the portability, the tool can be mounted to a piece of 12.5 mm or thicker plywood which can then be clamped to your work support or moved to other job sites and reclamped.
• When mounting your saw to a piece of plywood, make sure that the mounting screws do not protrude from the bottom of the wood. The plywood must sit fl ush on the work support. When clamping the saw to any work surface, clamp only on the clamping bosses where the mounting screw holes are located. Clamping at any other point will interfere with the proper operation of the saw.
• To prevent binding and inaccuracy, be sure the mounting surface is not warped or otherwise uneven. If the saw rocks on the surface, place a thin piece of material under one saw foot until the saw is fi rm on the mounting surface.

Mounting the saw blade (fig. D1 - D5)

To reduce the risk of injury, turn off tool and disconnect from power source before attempting to move it, changing accessories or making any adjustments accept as written in laser adjustment instructions.
Never depress the spindle lock button while the blade is under power or coasting.
Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product with this mitre saw.

• Depress the head lock up release lever (12) to release the lower guard (2), then raise the lower guard as far as possible.
• Using the Torx bit (33) in the handgrip end of the supplied wrench (23), loosen the guard bracket screw (34) suffi ciently to allow the angled corner piece (35) to pass between the head of the screw and the guard. This will allow the guard bracket (36) to be raised enough to permit access to the blade locking screw (37).
• With the lower guard held in the raised position by the guard bracket screw (34) depress the spindle lock button (14) with one hand, then use the supplied wrench (23) in the other hand to loosen the left-hand threaded blade locking screw (37) by turning clockwise.
  
  To use the spindle lock, press the button as shown and rotate the spindle by hand until you feel the lock engage. Continue to hold the lock button in to keep the spindle from turning. (fig. D4).
• Remove the blade locking screw (37) and the outside arbor collar (38).
• Install the saw blade (39) onto the shoulder (40) provided on the inside arbor collar (41), making sure that the teeth at the bottom edge of the blade are pointing toward the back of the saw (away from the operator).
• Replace the outer arbor collar (38).
• Tighten the blade locking screw (37) by turning counter-clockwise while holding the spindle lock engaged with your other hand.
• Move the guard bracket (36) down until the angled corner piece (35) is below the head of the guard bracket screw (34).
• Tighten the guard bracket screw.
  
  Never press the spindle lock while the blade is rotating. Be sure to hold the guard bracket down and firmly tighten the guard bracket screw after installing the blade.
  
  The guard bracket must be returned to its original position and the screw tightened before activating the saw. Failure to do so may allow the guard to contact the spinning saw blade resulting in damage to the saw and severe personal injury.

Adjustment

To reduce the risk of injury, turn off tool and disconnect from power source before attempting to move it, changing accessories or making any adjustments accept as written in laser adjustment instructions.
Your mitre saw was accurately adjusted at the factory. If readjustment due to shipping and handling or any other reason is required, follow the steps below to adjust your saw. Once made, these adjustments should remain accurate.

Instructions for use

Always observe the safety instructions and applicable regulations.
The attention of UK users is drawn to the "woodworking machines regulations 1974" and any subsequent amendments.
Prior to operation:

• Install the appropriate saw blade. Do not use excessively worn blades. The maximum rotation speed of the tool must not exceed that of the saw blade.
• Do not attempt to cut excessively small pieces.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
• Make sure all locking knobs and clamp handles are tight.
• Secure the workpiece.
• Although this saw will cut wood and many nonferrous materials, these operating instructions refer to the cutting of wood only.
  The same guide-lines apply to the other materials.
  Do not cut ferrous (iron and steel) materials, fi bre cement or masonry with this saw!
• Make sure to use the kerf plate. Do not operate the machine if the kerf slot is wider than 10 mm.

• To run the tool, press the on/off switch (1).
• To stop the tool, release the switch.

Body and hand position
Proper 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 fi nish cuts so that you can check the path of the blade.
• Do not cross your hands.
• Keep both feet fi rmly on the fl oor 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.
• Sight through the guard louvres when following a pencil line.

Setting the variable speed (fig. L)
The speed control dial (13) can be used for advance setting of the required range of speed.

• Turn the speed control dial (13) to the desired range, which is indicated by a number.
• Use high speeds for sawing soft materials such as wood. Use low speeds for sawing metal.

MIter Control (Fig. E1)
The mitre lever (4) and mitre latch (5) allows the saw to mitre 60 left and 50 right.
To miter the saw:

• Release the mitre lever (4) and depress the mitre latch (5) and set the mitre angle desired on the miter scale.
• Push down on the mitre lever (4) to lock the saw table in place.

Bevel Control (Fig. H1, J1)
The bevel latch levers (20) and bevel clamp handle (21) allows the saw to bevel 48º left and right. Your saw has two bevel latch levers (20), one on either side of the rear support housing. Only one needs to be used to move the bevel to either direction. The bevel clamp handle (21) is on top of the rear support housing.
To bevel the saw:

• Loosen the bevel clamp handle (21). Lift one of the levers to approximately 45º and set the bevel angle desired on the bevel scale (15). Two bevel scales are provided for convenience.
• Lock the bevel clamp handle (21) to lock the bevel in place. The bevel latch levers (20) can be lifted vertically to override the common stop angles.

Slide Stop (Fig. U)
The slide stop (18) control positions your saws rails so that the largest possible verticle moldings can be cut. ALWAYS TIGHTEN THE RAIL LOCK KNOB WHEN USING THE SLIDE STOP TO PREVENT THE SLIDE SYSTEM FROM MOVING UNINTENTIONALLY

Rail Lock Knob (fig. A1, U)
The rail lock knob (16) allows you to lock the saw head fi rmly to keep it from sliding on the rails. This is necessary when making certain cuts or when transporting the saw.

Grooving Stop (fig. A1, S)
The grooving stop (17) allows for groove cutting. Flipping the lever toward the front of the saw and adjusting the thumbscrew changes the depth of the groove cut. Flipping the lever toward the rear of the saw bypasses the grooving stop.

• 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.

Performing a sliding cut (fig. A1, N)
The guide rail allows cutting larger workpieces from 76.2 mm up to 111.8 mm using an out-down-back sliding motion.

• Release the rail lock knob (16).
• Pull the saw head towards you and switch the tool on.
• Lower the saw blade into the workpiece and push the head back to complete the cut.
• Proceed as described above.

• Do not perform sliding cuts on workpieces smaller than 76.2 mm.
• Remember to lock the saw head in the rear position when the sliding cuts are fi nished.

Mitre cross-cut (fig. A1, A2 & O)

• Release the mitre lever (4) and depress the mitre latch (5).
• Move the arm left or right to the required angle. The mitre latch will automatically locate at 10°, 15°, 22.5°, 31.62° and 45° both left and right. If any intermediate angle is required hold the head fi rmly and lock by tightening the mitre lever.
• Always ensure that the mitre lever is locked tightly before cutting.
• Proceed as for a vertical straight cross-cut.
  
  When mitring the end of a piece of wood with 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 cuts (fig. A1, A2 & P)
Bevel angles can be set from 48° left to 48° right and can be cut with the mitre arm set between zero and a maximum of 45° mitre position right or left.

Left bevel

• Slide the upper part of the left side fence (3) to the left as far as it will go.
• Loosen the bevel clamp handle (21), lift the bevel latch (20) and set the bevel as desired.
• The bevel latch automatically locates at 22.5°, 33.85° and 45°. If any intermediate angle is required, hold the head fi rmly and lock by tightening the bevel clamp handle (21).
• Proceed as for a vertical straight cross-cut.

Right bevel

• Slide the upper part of the right side fence (8) to the right as far as it will go.
• Proceed as for a left bevel cut.

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

Ensure that the material does not creep while cutting; clamp itsecurely in place. Always let the blade come to a full stopbefore raising the arm. If small fibres of wood still split out atthe rear of the workpiece, stick a piece of masking tape on thewood where the cut will be made. Saw through the tape andcarefully remove tape when finished.

Clamping the workpiece (fig. A6)

• Whenever possible, clamp the wood to the saw.
• For best results use the clamp (29) made for use with your saw. Clamp the workpiece to the fence whenever possible. You can clamp to either side of the saw blade; remember to position your clamp against a solid, flat surface of fence.

Support for long pieces (fig. A4)

• Always support long pieces.
• For best results, use the extension work support (27) to extend the table width of your saw (available from your dealer as an option). Support long workpieces using any convenient means such as saw-horses or similar devices to keep the ends from dropping.

Cutting picture frames, shadow boxes & other four sided projects (fig. Q1 & Q2)
Trim moulding and other frames
Try a few simple projects using scrap wood until you develop a "feel" for your saw. Your saw is the perfect tool for mitring corners like the one shown in fig. Q1. The joint shown has been made using either bevel adjustment.

• Using bevel adjustment
  The bevel for the two boards is adjusted to 45° each, producing a 90° corner. The mitre arm is locked in the zero position. The wood is positioned with the broad fl at side against the table and the narrow edge against the fence.
• Using mitre adjustment
  The same cut can be made by mitring right and left with the broad surface against the fence.

The two sketches (fig. Q1 & Q2) are for four side objects only. As the number of sides changes, so do the mitre and bevel angles. The chart below gives the proper angles for a variety of shapes, assuming that all sides are of equal length. For a shape that is not shown in the chart, divide 180° by the number of sides to determine the mitre or bevel angle.

No. of sides	Angle mitre or bevel
4	45°
5	36°
6	30°
7	25.7°
8	22.5°
9	20°
10	18°

Compound mitre (fig. R1 & R2)
A compound mitre is a cut made using a mitre angle (fig. Q2) and a bevel angle (fig. Q1) at the same time. This is the type of cut used to make frames or boxes with slanting sides like the one shown in fig. R1.

If the cutting angle varies from cut to cut, check that the bevel clamp knob and the mitre lock knob are securely tightened. These knobs must be tightened after making any changes in bevel or mitre (fig. R1 & R2).

• 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. R2) of your project and locate that angle on the appropriate arc in the chart. From that point follow the chart straight down to fi nd the correct bevel angle and straight across to fi nd the correct mitre angle.
• Set your saw to the prescribed angles and make a few trial cuts.
• Practice fi tting the cut pieces together.
• Example: To make a 4 sided box with 25° exterior angles (angle "A") (fig. R2), 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.
  

Cutting base mouldings
The cutting of base moulding is performed at a 45° bevel angle.

• Always make a dry run without power before making any cuts.
• All cuts are made with the back of the moulding laying fl at on the saw.

Inside corner

• Left side
  • Position the moulding with top of the moulding against the fence.
  • Save the left side of the cut.
• Right side
  • Position the moulding with the bottom of the moulding against the fence.
  • Save the left side of the cut.

Outside corner

• Left side
  • Position the moulding with the bottom of the moulding against the fence.
  • Save the right side of the cut.
• Right side
  • Position the moulding with top of the moulding against the fence.
  • Save the right side of the cut.

Cutting crown mouldings
The cutting of crown moulding is performed in a compound mitre. In order to achieve extreme accuracy, your saw has pre-set angle positions at 31.62° mitre and 33.85° bevel. These settings are for standard crown mouldings with 52° angles at the top and 38° angles at the bottom.

• Make test cuts using scrap material before doing the fi nal cuts.
• All cuts are made in a left bevel and with the back of the moulding against the base.

Inside corner

• Left side
  • Top of the moulding against the fence.
  • Mitre right.
  • Save the left side of the cut.
• Right side
  • Bottom of the moulding against the fence.
  • Mitre left.
  • Save the left side of the cut.

• Left side
  • Bottom of the moulding against the fence.
  • Mitre left.
  • Save the right side of the cut.
• Right side
  • Top of the moulding against the fence.
  • Mitre right.
  • Save the right side of the cut.

Grooving (fig. S)
Your saw is equipped with a grooving stop (17) and thumbscrew (59) to allow for groove cutting.

• Flip the grooving stop (17) towards the front of the saw.
• Adjust the thumbscrew (59) to set the depth of the groove cut. It might be necessary to release the lock nut (60) fi rst.
• Place a piece of scrap material of approx. 5 cm between fence and workpiece in order to perform a straight groove cut.

Special Set-up for Wide Crosscuts (fig. A1, T1, T2)
Your saw can cut very wide (up to 391 mm) workpieces when a special set up is used. To set the saw up for these workpieces, follow these steps:

• Remove both left and right sliding fences from the saw and set aside. To remove them, unscrew the fence knobs several turns and slide each fence outward. Adjust and lock the miter control so that it is at 0 degrees miter.
• Remove backfence screws (64) from right rear foot and install them into the right hand fence (8) screw holes.
  
  Do not cut material using the special setup without properly installing the backfence screws (64), otherwise the material will not be supported properly and may cause loss of control and possible injury.
• Make a platform using a piece of 38 mm thick particleboard or similar fl at strong 38 mm thick wood to the dimensions: 368 x 660 mm. The platform must be fl at otherwise the material could move during cutting and cause injury.
• Mount the 368 x 660 mm platform to the saw using four 76.2 mm long wood screws (61) through the holes in the base fence. Four screws must be used to properly secure the material. When the special set up is used, the platform will be cut into two pieces. Ensure the screws are tightened properly otherwise material could loosen and cause injury. Ensure the platform is fi rmly fl at on the table, against the fence, and centered evenly from left to right.
  
  Ensure the saw is mounted fi rmly to a stable fl at surface. Failure to do so could cause the saw to be unstable and fall causing personal injury.
• Place the workpiece to be cut on top of the platform mounted to the table. Ensure the workpiece is fi rmly against the backfence.
• Secure the material before cutting. Cut slowly through the material using a out-down-and-back motion. Failure to clamp securely or cut slowly could result in the material coming loose and causing injury. After several cuts are made at various miter angles other than 0º, the platform may weaken and not properly support the work. Install a new, unused platform to the saw after presetting the desired miter angle.
  
  Continued use of a platform with several kerfs may cause loss of material control and possible injury.

Dust extraction (fig. A2 & A3)

• Fit the dustbag (26) onto the dust spout (6).
• Whenever possible, connect a dust extraction device designed in accordance with the relevant regulations regarding dust emission.

Saw blades
To obtain the stated cutting capacities, always use 305 mm saw blades with 30 mm arbor holes.

Transporting (fig. A1, A2 & B)
In order to conveniently carry the mitre saw, a carrying handle (10) has been included on the top of the saw arm.

• To transport the saw, lower the head and depress the lock down pin (22).
• Lock the rail lock knob with the saw head in the front position, lock the mitre arm in the full left mitre angle, slide the fence (3 & 8) completely inward and lock the bevel lever (20) with the saw head in the vertical position to make the tool as compact as possible.
• Always use the carrying handle (10) or the hand indentations (24) shown in fig. B to transport the saw.
