Maintenance

To prevent injury or electrocution,
always unplug the tool from the power supply outlet
before performing any maintenance or repair work
on the tool!
Any maintenance or repair work
that requires opening of the motor or gear housing
should be carried out only by an authorized Cus-
tomer Service Center (see your dealer for informa-
tion on locating a service center). Maintenance or
repair work carried out by an unauthorized person
can lead to improper connection of electrical wires,
misadjustment, 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 ventila-
tion openings. Low-pressure (30 psi) compressed
air may be used on other components, but personal
safety protection should be employed (hearing, vi-
sion, and respiratory).
Certain cleaning agents and solvents
are harmful to plastic parts. Some of these include,
but are not limited to: Gasoline, Acetone, Methyl
Ethyl Ketone (MEK), Carbonyl Chloride, clean-
ing 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 standstill.
20.1
Routine Maintenance
The Domino tenon joiner does not require much
routine maintenance except for cleaning. For best
performance and long life of the Domino tenon
joiner, keep the machine clean.
– To ensure proper cooling of the tool and motor,
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 saw-
dust.
– Always use the Domino joiner with a dust col-
lection system.
– Periodically inspect the mortising bit(s) for dam-
age, 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.
– For best results, only the tip of the bit should be
ground, not the sides.
– The maximum tip material removal from sharp-
ening before the bit must be replaced is approxi-
mately 1mm. Any more than this and the bit will
be too short for proper fi t of the tenons.
Cleaning and Maintenance
– Blow off the exterior of the machine with
low-pressure compressed air to remove saw-
dust, but do not blow air directly into the
air cooling vents on the back of the mo-
tor as this can drive debris into the motor.
– Blow out impacted sawdust from the mortising
bit area.
– Do not remove the fence body from the motor
housing when the joiner is coated with saw-
dust.
– With the exterior of the joiner free from sawdust,
remove the fence body from the motor housing
and clean the linear slides:
• With a soft cotton cloth, wipe down the linear
rails.
• With compressed air, blow out any dust from
inside the linear bores.
• With a soft cotton cloth, wipe down the interior
of the bronze linear bearings.
– With a clean cotton cloth (not the same
cloth used previously), apply a coating of
light-weight machine oil to the linear rails.
