DeWalt DW720 Manual page 35

• Loosen the two screws (73) and move the pointer (71) until the edge of
the out-rip pointer (74) lines up with the known width of the board on
the lower scale (fig. G3).
• Tighten the two screws (73) (fig. G3).
• Place the motor in in-rip position.
• Raise the guard to allow the blade to rest against the face of the fence.
• The in-rip pointer (75) should now line up with the zero position in the
upper scale. Adjust if necessary (fig. G3).
Bevel scale (fig. G4)
• Check that the bevel scale (20) reads 0° when positioned for a vertical cut.
• If required, loosen the screws (47) and adjust the pointer to 0°.
Mitre scale (fig. G5)
• Check that the mitre scale (76) reads 0° when positioned for a vertical cut.
• Adjust the pointer (77) to register 0° using the screw (78).
The mitre scale has preset positions at 45° left and right and at 0°.
Yoke travel stop (fig. A2, H1 & H2)
The yoke travel stop (14) must be adjusted to avoid that the bearings on
the yoke assembly hit the rear limit of the bearing tracks (fig. A2).
• Push the yoke assembly as far as it will go, pull it forwards approx. 5 mm
and lock it the using the riplock (15) (fig. A2).
• Adjust the yoke travel stop (14) by slackening the nuts (79) in the front
slot (80) until the rubber stop (81) butts against the back of the riplock
housing (fig. H1).
• Tighten the nuts (79).
When cross-cutting, tighten one nut in the front slotted hole
and one in the rear slotted hole (fig. H2).
Mounting the return spring (fig. J)
• Mount the return spring (82) behind the yoke travel stop (14) using the
corresponding bolts and attach the end of the cable to the riplock (15)
using the screws (83).
Consult your dealer for further information on the appropriate accessories.
Instructions for use
• Always observe the safety instructions and applicable
regulations.
• Ensure the material to be sawn is firmly secured in place.
• Apply only a gentle pressure to the tool and do not exert side
pressure on the saw blade.
• Avoid overloading.
• 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.
• Never run the machine without the guards in place.
• Never lift the machine by the table top.
• Always refer to figure K to check the fence position and type.
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 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.

• I = ON The tool now works in continuous operation.
• O = OFF
Making a trial cut (fig. A1)
• 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.
• 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. K1 - K5)
The teeth of a new blade are very sharp and can be dangerous.
Cross-cutting (fig. A1 & K1)
• 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 & K3)
• 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, you may have to slide the fence
and the strips to the left.
Bevel cuts (fig. A1, D2 & K2)
• Set the arm as for a 0° cross-cut.
• Raise the blade well above the table surface.
• Release the bevel clamp lever (19) and pull out the bevel latch (21) (fig. D2).
• Tilt the motor to the required angle on the bevel scale (20) (fig. A1).
• For 90° or 45° right, engage the bevel latch (21) and lock with the bevel
clamp lever (19).
• For intermediate angles, use the bevel clamp lever only.
• Proceed as for a vertical cross-cut.
Ripping (fig. K5, F2, G1 & G2)
The motor can be locked in in-rip or out-rip position as shown in figures G1 &
G2 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 (49) and press the yoke latch (50) to rotate
the motor to the appropriate position until it locks in place (fig. G1).
• Tighten the yoke clamp lever (49) and position the fence accordingly.
• Position the yoke along the arm for the desired width of cut, using the
rip scale (72) and lock it in position using the riplock.
