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.

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 

 

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.

3.  Loosen the mortising bit by turning it counterclockwise 

(standard right-hand thread).

4.  Insert a new mortising bit, and start the threads by hand 

to avoid cross-threading.

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.
