Changing The Mortising Bit; Operation - Festool DOMINO DF 500 Guide D'utilisation

(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.)

– Press in on the depth adjust lock [8.1].
– Move the depth adjust lever [8.2] to the
stepped position of the desired depth.
– Release the depth adjust lock [8.1].

Changing the Mortising Bit

Different mortising bits are available for a va-
riety of Domino tenon sizes. The DF500 comes
equipped with a 5mm bit, and 6, 8, and 10
mm bits are available as an option.
Always unplug the tool before
changing mortising bits, or removing the
fence body from the motor housing.
– Using the provided 8 mm wrench, pry up
on the fence body release lever [9.1], and
slide the fence body off the motor housing
(see fi g. 2 on the fold-out page).

– Press and hold the spindle lock button
[10.1]. This stops the spindle from turning
while you loosen the mortising bit.

– Loosen the mortising bit [10.2] by turning
it counterclockwise (standard right-hand
thread).
– Insert a new mortising bit, and start the
threads by hand to avoid cross-threading.
– Press in on the spindle lock [10.1] while
tightening the bit. Do not over tighten the
bit.
– Carefully reinstall the fence body onto the
motor housing, and push the fence body in
until the latch clicks.
Notes:
Make sure there is no dust inside the guide
tubes before inserting the fence body.
Be careful not to damage the linear bear-
ings (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.

Operation

Please observe the following
rules when working:
The mains voltage must correspond to the
specifi cation on the rating plate.
Always secure the workpiece in such a
manner that it cannot move while being
sawed.
Always hold the Domino dowel jointer with
both hands at the motor housing and at
the additional handle. This reduces the risk
of injury and is a prerequisite for precise
work.
Close the clamping lever for jointing height
adjustment [2.3] and the clamping lever
for the angle guide [1.5] so that accidental
release during operation is impossible.
Adapt the feed rate to the jointer bit diam-
eter and material. Work with a constant
feed rate.
