Supplemental Owner’s Manual 19
Maintenance
WARNING! Any maintenance or repair work
that requires opening of the motor or gear hous-
ing should be carried out only by an authorized
Customer Service Center (see your dealer for
information on locating a service center).
WARNING! To reduce the risk of electrocution or
other personal injury, always unplug the tool from
the power supply outlet before performing any
maintenance or repair work on the tool.
NOTICE: Do not use compressed air to clean the
motor housing of the tool, as you could inject for-
eign objects into the motor through the ventilation
openings.
NOTICE: 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, cleaning solutions
containing Chlorine, Ammonia, and household clean-
ers containing Ammonia.
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 linear rails, guide tubes, and linear bearings
clean and free from sawdust.
► Never store the joiner with the fence body separated from
the motor housing, as this can permit dust and debris to
enter the guide tubes.
► 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 qualied
sharpening service.
► For best results, only the tip of the bit should be ground,
not the sides.
Cleaning and Maintenance
1. 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 motor.
2. Blow out impacted sawdust from the mortising bit area.
NOTICE: To avoid getting debris inside the guide
tubes, do not remove the fence body from the motor
housing when the joiner is coated with sawdust.
3. With the exterior of the joiner free from sawdust, remove
the fence body from the motor housing and clean the
slide components:
a. With a soft cotton cloth, wipe down the linear rails.
b. With low-pressure compressed air, blow out any dust
from inside the guide tubes.
c. With a soft cotton cloth, wipe down the interior of the
linear bearings (interior of the guide tubes).
4. With a clean cotton cloth (not the same cloth used previ-
ously), apply a coating of light-weight machine oil to the
linear rails and/or linear bearings.
5. Replace the fence body, and with the plunge depth set to
maximum, plunge the joiner in and out several times to
spread the lubricant into the internal linear bearings.
6. Wipe off the excess oil from the linear rails.
