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), Car-
bonyl 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.
– For best results, only the tip of the bit
should be ground, not the sides.
– The maximum tip material removal from
sharpening before the bit must be replaced
is approximately 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
sawdust, but do not blow air directly into
the air cooling vents on the back of the
motor as this can drive debris into the mo-
tor.
– Blow out impacted sawdust from the mor-
tising bit area.
– Do not remove the fence body from the
motor housing when the joiner is coated
with sawdust.
– 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.
• Use a lightweight machine oil such as
"sewing machine" oil or pneumatic tool
oil.
• Do not use a penetrating oil as these may
contain solvents and detergents that can
remove the impregnated lubricant from
the bronze bearings.
• Do not use a rust inhibiting fl uid/oil as
these have limited lubrication properties,
and can also remove the impregnated
lubricant from the bronze bearings.
– With the plunge depth set to maximum,
plunge the joiner in and out several times
to spread the lubricant into the internal
bronze bearings.
– Remove the fence body from the motor
housing and wipe off the excess oil from
the linear rails.
– Replace the fence body onto the motor
housing.
– Never store the joiner with the fence body
separated from the motor housing, as this
can permit dust and debris to enter the
linear slide.
