to join them correctly again once you have
cut the dowel holes.

against one another and mark the de-

– Set the desired dowel-hole width [19.1].
Our recommendation: Cut the fi rst hole with-
out play (dowel-hole width = Domino dowel
width), and the remaining dowel holes to the
next largest dowel-hole width. The fi rst dowel
hole therefore serves as a reference dimen-
sion, whereas the remaining dowel holes have
tolerance for manufacturing inaccuracies.

– Cut the fi rst dowel hole by placing the stop
pin at the side edge of the workpiece.
– Set the mortise width dial [20.1] to the next
largest dowel-hole width.
– Cut the following dowel holes according to
the pencil markings made beforehand and
the scale of the viewing window [20.2].

Maintenance

To prevent injury or electrocu-
tion, always unplug the tool from the power
supply outlet before performing any mainte-
nance or repair work on the tool!
19.1
20.1
Any maintenance or repair work
that requires opening of the motor or gear
housing should be carried out only by an au-
thorized Customer Service Center (see your
dealer for information on locating a service
center). Maintenance or repair work carried
out by an unauthorized person can lead to
improper connection of electrical wires, mis-
adjustment, or damage to components, which
can result in injury.
Do not use compressed air to
clean the motor housing of the tool, as you
could inject foreign objects into the motor
through the ventilation openings. Low-pres-
sure (30 psi) compressed air may be used on
other components, but personal safety pro-
tection should be employed (hearing, vision,
and respiratory).
Certain cleaning agents and sol-
vents are harmful to plastic parts. Some of
these include, but are not limited to: Gasoline,
Acetone, Methyl Ethyl Ketone (MEK), Carbo-
nyl Chloride, cleaning solutions containing
Chlorine, Ammonia, and household cleaners
containing Ammonia.
The tool is fi tted with special motor brushes
with an automatic cut-out. When the brushes
become worn the power supply is shut off
automatically and the tool comes to a stand-
still.
Routine Maintenance
The Domino tenon joiner does not require
much routine maintenance except for clean-
ing. For best performance and long life of
the Domino tenon joiner, keep the machine
clean.
– To ensure proper cooling of the tool and mo-
tor, the cooling vents in the motor housing
must always be kept clear and clean. Keep
the motor cooling inlets at the back of the
handle clean and free from sawdust.
– Keep the linear rails clean and free from
sawdust.
– Always use the Domino joiner with a dust
collection system.
– Periodically inspect the mortising bit(s) for
damage, wear, or dullness. Re-sharpen or
replace the bits as necessary.
– Never attempt to sharpen the mortising
bits yourself. The mortising bits should be
sharpened only by a qualifi ed sharpening
service.
