Working With The Machine - Festool DOMINO DF 500 Q Original Operating Manual

DF 500 Q
- 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 mo-
tor unit.
- Slide the angle stop all the way down.
- Close the clamping lever [6-1].
Always release the clamp lever [6-1]
before 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 pos-
sible with the machine running!
The following dowel-hole settings are possible
(Fig. 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 Additional stop with extension
The additional stop [8-1] can be used to enlarge
the contact surface when jointing on the work-
piece 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 posi-
tion the dowel closer to the edge.
- Secure the additional 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].

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
influence the degree of working accuracy (e.g.
fast-feed speed). Furthermore, the dimensions of
wooden DOMINOs may vary (for example, due to
16
humidity), regardless of how they are stored. All of
these factors influence the dimensional accuracy
of manufactured dowel holes and dowelling joints.
Numerous tests have been run to produce an
average figure 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] fitted
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 final 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
during 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.
- Use the machine only with the guide frame
mounted.
Procedure
Proceed as follows to create a dowelled joint:
- Select a Domino dowel and insert a match-
ing jointing bit in the Domino dowel jointer
(Chap. 7.1).
- Set the jointing depth (Chap. 7.2). The jointing
depth must be at least 3 mm smaller than the
workpiece thickness so that the dowelled joint
is supportable.
- Set the jointing height to correspond to the
workpiece thickness (Chap. 7.3).
- Mark the areas on the workpiece that belong
together [10-1] so that you will be able to join
them correctly again once you have cut the
dowel holes.
- Position the two workpieces to be joined against
