Setting The Mortise Width; Setting The Mortise Depth - Festool DOMINO DF 500 Instruction Manual

– Loosen the fence height locking [5.3] lever
by turning it ¼-turn counterclockwise.
– Make sure the board thickness gauge [5.2]
is retracted out of the way (at its lowest
setting).
– Raise or lower the fence until the pointer is
pointing to the desired height on the gauge
[5.1].
– Tighten the locking lever [5.3].
Board Thickness Gauge
The numbers printed on the gauge [5.2]
represent the thickness of the workpiece (in
mm) and the mortise height will be centered
in the workpiece. Use this gauge for setting
the fence height based on the thickness of
the workpiece without needing to calculate
the center distance.
Do not use the board thickness
gauge for mitered joints, because this will
place the mortise too close to the edge of
the joint.
– Loosen the fence height locking lever [5.3]
by turning it ¼-turn counterclockwise.
– Raise the fence above the board thickness
gauge [5.3].
– Slide the gauge in or out until the thickness
of the workpiece (in mm) is shown in the
window.
– Lower the fence down until it touches the
gauge.
– Tighten the locking lever [5.3].

Setting the Mortise Width

The width of the mortise slot can be increased
by the mortise width dial [6.1] to permit some
side-to-side fl exibility in the tenon position.

6.1
In the standard (smallest) position [A], the
Domino tenon will fi t snugly into the mortise
slot. The width of the mortise slot is 13 mm +
diameter of jounter bit. In the middle position
[B], the mortise slot will be 6 mm wider than
the Domino tenon. In the widest position [C]
the mortise slot will be 10 mm wider than the
Domino tenon.
Failure to follow the notes below
may result in damage to the tool.
Never force the dial to turn.
Rotate the adjustment dial only when the
motor is running.
Never rotate the dial during a plunging
operation. This can bend or break the
mortising bit, and can also damage the
machine.

Setting the Mortise Depth

The mortising depth determines how deep into
the workpiece the mortising bit penetrates.
This needs to be adjusted for different sized
tenons.
7
In most cases, the tenon should be centered
across the joint, and the depth of the mortise
should be ½ the length of the tenon. How-
ever, in some cases you may want to have
more of the tenon in one piece than the other
