20 Domino DF 500 Tenon Joiner
Maintenance
WARNING! Any maintenance or repair work that
requires opening of the motor or gear housing
should be carried out only by an authorized
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, misadjustment, or
damage to components, which can result in
electric shock or other injury.
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
foreign objects into the motor through the
ventilation openings. Low-pressure (30 psi)
compressed air may be used on other
components, but personal safety apparel should
be worn (i.e. hearing, eye, and respiratory
protection).
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 cleaners 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 motor cooling inlets at the
back of the handle clean and free from sawdust.
►
Always use the Domino joiner with a dust collection
system (see page 11).
►
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
qualified 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 fit of the tenons.
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
previously), apply a coating of light-weight machine oil
to the linear rails and/or linear bearings.
►
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 linear bearings.
►
Do not use a rust inhibiting fluid/oil (such as a water
displacement product) as these have limited
lubrication properties, and can also remove the
impregnated lubricant from the 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.
Remove the fence body from the motor housing and
wipe off the excess oil from the linear rails.
7.
Replace the fence body onto the motor housing.
