Setting the Mortise Depth
The mortising depth determines how deep into the work- piece the mortising bit penetrates. This needs to be adjusted for different sized tenons. In most cases, the tenon should be centered across the joint, and the depth of the mortise should be ½ the length of the tenon. However, in some cases you may want to have more of the tenon in one piece than the other (lower Domino tenon pictured below). In this case, the sum of the two depths must equal the length of the tenon. (In the offset tenon example below, the Domino tenon is 50 mm long, the left mortise is 35 mm deep, and the right mortise is 15 mm deep.)
If you are frequently switching depth settings, use the two limit stops to assist in setting those positions. This is also helpful when working with thin materials and you set the maximum limit to be less than your material thickness.
To set the depth position, press down on one of the two release buttons, and slide the adjustment pointer to the desired setting.

Changing the Mortising Bit
Different mortising bits are available for a variety of Domino tenon sizes. The DF 700 comes equipped with a 12mm bit; and 8, 10, and 14 mm bits are available as an option.
WARNING! To reduce the risk of injury from contact with a moving mortising bit, always unplug the tool before changing mortising bits or removing the fence body from the motor housing.
1.Using the provided 12mm wrench, pry up on the fence body release lever, and slide the fence body off the motor housing. (The inset photograph on page 6 shows the fence body and motor housing when separated.)

2.Press and hold the spindle lock button. This stops the spindle from turning while you loosen the mortising bit.

4.Insert a new mortising bit, and start the threads by hand to avoid
5.Press in on the spindle lock while tightening the bit. Do not over tighten the bit.
6.Carefully reinstall the fence body onto the motor housing, and push the fence body in until the latch clicks.
►► Make sure there is no sawdust inside the guide tubes (hollow tubes) before inserting the fence body.
►► Be careful not to damage the linear bearings (inner sur- face of guide tube) when reinstalling the fence body. If it does not slide on easily, it means the fence is skewed with respect to the bearings.
