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

Ensure that the jointing depth is at
least 3 mm smaller than the workpiece
thickness. Otherwise the jointer bit can
emerge from the workpiece at the rear
side, which involves an increased risk of
injury.
7.3 Setting jointing height
a) with selection slide
- Release the clamping lever [6‑1] for jointing
height adjustment.
- Using the additional handle [6‑2], raise the front
section of the guide frame.
- Use the slide [6‑6] to set the desired board
thickness (16 mm, 20 mm, 22 mm, 25 mm,
28 mm, 36 mm, 40 mm).
- Press the front section of the guide frame down-
wards as far as the stop.
- Close the clamping lever [6‑1].
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 mo-
tor 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]
steplessly 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 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
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).
