Festool DF 500 사용자 설명서

The mortising depth determines how deep into the 

workpiece 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 40 mm long, the left mortise is 28 mm deep, and the 

right mortise is 12 mm deep.) 

 

1. 

Press in on the depth adjust lock. 

2. 

Move the depth adjust lever to the stepped position of 

the desired depth. 

3. 

Release the depth adjust lock. 

 

 

Different mortising bits are available for a variety of Domino 

tenon sizes. The DF500 comes equipped with a 5mm bit, and 

6, 8, and 10 mm bits are available as an option. 

  WARNING: Always unplug the tool before changing 

mortising bits, or removing the fence body from the 

motor housing. 

1. 

Using the provided 8mm wrench, pry up on the fence 

body release lever, and slide the fence body off the 

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 

before inserting the fence body. 

► 

Be careful not to damage the linear bearings (hollow 

tubes) when reinstalling the fence body. If it does not 

slide on easy, it means the fence is skewed with respect to 

the bearings.
