Troubleshooting

Possible causes and corrections
Check that the cord is properly plugged into an outlet.
Make sure the Plug-it connector is properly inserted and fully
tightened.
Make sure the outlet has power. Check the circuit breaker or try
another outlet.
If used with a Festool dust extractor, make sure the selector switch
is pointing to „Auto". The auxiliary outlet on the dust extractor has
power only when the selector is at Auto.
Inspect the power cord (including extension cords) for damage or
missing prongs.
The motor brushes may have worn and need replacement.
Clean the linear rails and bronze bearings of the plunge slide, and
make sure they are properly lubricated.
Inspect the bronze linear bearings for damage. Improper insertion
of the fence body onto the motor housing can damage the linear
bearings.
Make sure you hold the Domino joiner fi rmly in position while
plunging the mortise slot.
Make sure the mortise width setting is correct.
Make sure you are using the correct mortising bit for the size of
the Domino tenon.
The Domino tenons may have shrunk in an overly dry or warm
environment. This is normal wood movement.
Check the mortising bit to ensure it is not bent. A bent bit will make
a thicker and wider mortise slot than desired.
The most common cause for this is that the tenons are stored in a
humid environment, and they have swelled from moisture absorp-
tion. Store the tenons in a cool dry environment.
The mortising bit may have been improperly sharpened or sharp-
ened too many times. Replace the bit.
Make sure the workpiece is securely clamped before plunging.
Check the Stop latchs.
Check the calibration of the Horizontal Position Gauge (sight
gauge).
Don't plunge the mortising bit into the work too fast. This may
cause the joiner to move during the plunge.
Make sure the friction pads on the front of the joiner are not worn,
damaged, or missing.
Take care not to tilt the joiner while plunging.
If the mortise slots were registered from the bottom of the base-
plate, make sure there is no dust or debris under the joiner.
Make sure the fence is properly locked at the desired height set-
ting.
Inspect the height adjustment lock to ensure it is not broken (slip-
ping).
