Additional Safety Rules for Radial Arm Saws

- Protect the electric power supply with a suitable fuse or circuit breaker.

- Keep the bearing tracks in the arm and the bearings on the roller head assembly clean and free from grease.

- Before switching ON, make sure that the fence is in the correct position. The blade should not contact the material until the saw is pulled by the handle.

- Always set the finger guard so that it passes through the pre-cut slot in the fence and/or 3 mm above the surface of the material being cut (except when ripping).

- When ripping, keep the riving knife adjusted to the correct distance from the blade (1 - 3 mm) and make sure the kickback fingers are properly adjusted.

- When ripping, always check the direction of feed.

- Regularly check the adjustments for accuracy and adjust as required.

- Make sure that the blade rotates in the correct direction and that the teeth are pointing towards the fence.

- Make sure all clamp handles are tight before starting operation.

- Never run the machine without all guards in place.

- When not in use, protect the saw blade completely using the blade guard.

- When not in use, when changing blades or carrying out maintenance, disconnect the machine from the power supply.

- Always use sharp blades of the correct type designed for the workpiece. The recommended blade diameter is stated in the technical data.

- Do not wedge anything against the motor fan to hold the motor shaft.

- Do not force the cutting action. (Stalling or partial stalling of the motor can cause major damage. Allow the motor to reach full speed before cutting.)

- Do not lift the machine by its worktable.

- Do not cut ferrous metals, non-ferrous metals or masonry.

- Do not apply lubricants to the blade when it is running.

- Do not place either hand in the blade area when the saw is connected to the power source.

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.

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 qualified 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 fit 13 Amperes BS1363A approved plugs fitted 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 firmly and that the two leads are correctly fixed at the terminal screws.

The attention of UK users is drawn to the “woodworking machines regulations 1974” and any subsequent amendments.

Switching ON and OFF (fig. A1)

The ON/OFF-switch (1) of your radial arm saw offers multiple advantages:

• no-volt release function: should the power be shut OFF for some reason, the switch has to be deliberately reactivated.
• motor overload protection device: in case of motor overload, the power supply to the motor will be cut OFF (In the DW728, the motor overload protection device is situated on top of the motor).
• Green button = ON The tool now works in continuous operation.
• Red button = OFF
• Isolating switch (2) (DW729) = manual rotary switch to cut OFF all power to the unit.
• Emergency stop (17) = cut OFF all power to the unit (fig. A2). To release the emergency stop, rotate it clockwise.

Making a trial cut (fig. A1, N1 & N2)

Figure N1 shows the standard position of the fence for cross-cutting and in-rip. Figure N2 shows the standard position of the fence for ripping wide panels. To release the fence, loosen the table clamps (7) (fig. N1).

• With the mitre latch lever (9) engaged, lock the mitre clamp lever (10) so that the blade is positioned for a straight 0^ cross-cut.
• Release the riplock (15) and push the yoke assembly back until the blade is behind the fence (fig. A1).
• Lower the arm until the blade almost touches the table top.
• Place the workpiece against the front of the fence.
• Switch ON and lower the arm to allow the blade to cut a shallow groove in the table surface.
• Pull the blade towards you so that it cuts a vertical slot in the wooden fence and through the workpiece.
• Return the blade back to rest position and switch OFF.
• Check that the cut is a true 90^ in all planes and adjust if required.

Basic Saw Cuts (fig. 01 - 02)

The teeth of a new blade are very sharp and can be dangerous.

Cross-cutting (fig. A1)

• Set the radial arm at right angles to the fence.
• Engage the mitre latch lever (9) in 0^ position and tighten the mitre clamp lever (10) (fig. A1).
• Lower the blade.
• Adjust the finger guard so that it just clears the workpiece.
• If there is no slot in the table top, cut one as described above.

• Hold the workpiece against the fence, keeping your fingers well away from the path of the blade.

• Switch ON and slowly pull the blade though the fence and the workpiece.

• Return the blade to rest position and switch OFF.

Mitre cuts (fig. A1 & O1)

• Release the mitre latch lever (9) and the mitre clamp lever (10) (fig. A1).
• Swing the arm to the required angle on the mitre scale.
• For 45^ left or right, engage the mitre latch lever (9) and lock with the mitre clamp lever (10).
• For intermediate angles, use the mitre clamp lever only.
  • Proceed as for cross-cutting.

In the case of left-hand mitre, use the rear fence position.

Bevel cuts (fig. A1, G2 & O2)

• Set the arm as for a 0^ cross-cut.
• Raise the blade well above the table surface.
• Release the bevel clamp (20) and pull out the bevel latch (22) (fig. G2).
• Tilt the motor to the required angle on the bevel scale (21) (fig. A1).
• For 90^ or 45^ right, engage the bevel latch (22) and lock with the bevel clamp (20).
• For intermediate angles, use the bevel clamp only.
  • Proceed as for a vertical cross-cut.

Ripping (fig. H2, J1 & J2)

The motor can be locked in in-rip or out-rip position as shown in figures J1 & J2 to adapt the machine to narrow and wide workpieces respectively.

• Lock the yoke in pulled out position using the riplock.
• Release the yoke clamp lever (23) and press the yoke latch (52) to rotate the motor to the appropriate position until it locks in place (fig. J1).
• Tighten the yoke clamp lever (23).
• Position the yoke along the arm for the desired width of cut, using the rip scale (76) and lock it in position using the riplock.
• Adjust the blade guard as described above and turn the dust extraction adaptor (58) away from your face (fig. H2). Remember that ripping requires the use of the riving knife (61) and the anti-kickback fingers (59) (fig. J2).
• Slowly feed the workpiece into the blade, keeping it firmly pressed onto the table and against the fence. Allow the teeth to cut and do not force the workpiece through the blade. The blade speed should be kept constant.

Always use a push stick.

Bevel ripping

• Set the machine in the bevel crosscut position.
• Rotate the yoke into rip position.
• Position the yoke for the correct ripping width.
• Angle the anti-kickback fingers so that they will be flat on the workpiece and lower the riving knife.
• Proceed as for ripping.

Compound mitre

This cut is a combination of a mitre and a bevel cut.

- Set the required bevel angle.

- Swing the arm to the required mitre position.

• Proceed as for mitre cuts.

Always switch OFF the tool when work is finished and before unplugging.

Dust extraction (fig. H1)

The machine is provided with a dust extraction adaptor (58).

• Whenever possible, connect a dust extraction device designed in accordance with the relevant regulations regarding dust emission.
• When cross-cutting, position a dust collection chute (option) behind the line of cut.

Optional Accessories

Prior to assembling any accessories always unplug the machine.

The Dado head (fig. F1, P1 & P2)

Figure P1 shows the parts composing the dado head. The dado head allows to cut wide, deep cuts in one pass.

Sharp edges.

Mounting the dado head

• Remove the blade guard assembly and the blade.
• Place one cutter blade (94) onto the shaft, making sure that the teeth point downwards.
• Mount the required number of intermediate blades (95) to achieve the required width of cut and finally the other cutter blade (94).
• Secure the dado head using the standard arbor nut (38) (fig. F2).
• Remove the riving knife and its support bracket from the blade guard assembly and mount the guard.
• Lower the dado head into position for the depth of cut required.

Using the dado head

• In crosscut or mitre position
• Adjust the anti-kickback fingers up and out of the way.
• Adjust the finger guard correctly.
• In ripping position
• Adjust the anti-kickback fingers correctly.

Traverse control (fig. A1, K, Q1 - Q3)
