b) freely selectable
- Release the clamping lever (6.1) for jointing
height adjustment.
- Using the additional handle (6.2), raise the front
section of the guide frame.
- Push the slide (6.6) to the stop in direction motor
unit.
- Set the desired jointing height using the scale
(6.3) by moving the front section of the guide
frame vertically.
- Close the clamping lever (6.1).
7.4 Setting angle guide
- Release the clamping lever for the angle guide
(6.4).
- Set the desired angle: using the scale (6.5) step-
lessly from 0° - 90°, or in notches at 0°, 22.5°,
45°, 67.5°, 90°.
- Close the clamping lever (6.4).
Mitre cutting thin workpieces
- Set the desired angle.
- Release the clamping lever (6.1) for jointing
height adjustment.
- Push the slide (6.6) to the stop in direction motor
unit.
- Slide the angle stop all the way down.
- Close the clamping lever (6.1).
Always release the clamp lever (6.1) be-
fore resetting the angle stop.
7.5 Setting dowel-hole width
Reliable setting of the dowel-hole width
with the rotary switch (1.2) is only possible
with the machine running!
The following dowel-hole settings are possible
(image 7a):
13 mm + jointer bit diameter
19 mm + jointer bit diameter
23 mm + jointer bit diameter
7.6 Dust extraction
Always connect the machine to a dust
extractor. You can connect a Festool ex-
tractor with an extractor hose diameter
of 27 mm to the extractor connector (2.2).
7.7 Side stop with extension
The side stop (8.1) can be used to enlarge the con-
tact surface when jointing on the workpiece edge,
thus allowing safer guidance of the machine.
The distance to the centre of the routed hole can
be reduced from 37 mm to 20 mm using the two
integral stop spacers (8.6), allowing you to position
the dowel closer to the edge.
- Secure the side stop to the threaded bores (8.3)
on the guide frame using both screws (8.2),
whereby the contact areas of the support ring
(8.5) and the table (8.4) must be level with one
another.
- Swivel one of the distance spacers (8.6) out-
wards to reduce the distance (see Fig. 8). The
spacer aligns automatically with the stop latch
(8.7).
8 Working with the machine
Wood is a natural, non-homogenous material and
because of this, its dimensions will most likely
deviate slightly during processing, even if the
machine is set accurately. Machine handling also
infl uence the degree of working accuracy (e.g.
fast-feed speed). Furthermore, the dimensions
of wooden DOMINOs may vary (for example, due
to humidity), regardless of how they are stored.
All of these factors infl uence the dimensional
accuracy of manufactured dowel holes and dow-
elling joints.
Numerous tests have been run to produce an
average fi gure for these dimensional discrepan-
cies. The dimensions of the machine and DOMINO
dowels are based on these averages. If a lateral
offset of approx. 0.03 mm - 0.04 mm occurs when
two workpieces are joined together, you have the
option of replacing the stop latches (2.4) fi tted
on delivery with correction stop latches. These
latches are 0.15 mm narrower and reduce the
lateral clearance of the dowel holes in relation
the edge of the workpiece (see Chapter 14).
Prior to processing the fi nal workpiece, it is advis-
able to optimise the dowel-hole depth, width and
diameter using a sample workpiece.
Please observe the following rules when
working:
- 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 dur-
ing operation is impossible.
- Adapt the feed rate to the jointer bit diameter
and material. Work with a constant feed rate.
- Only lay the Domino dowel jointer aside when the
jointer bit has come to a complete standstill.
