Festool Domino DF 500 - Manual (Page 9)

Setting the Mortise Depth
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.
Changing the Mortising Bit
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! 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 8mm 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.
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
surface 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.
