Work Piece C-1
Cutting of work piece on a circular saw before notchin
g
Before the notching of the work piece it must be cut to the correct length on a circular saw.
It is very important that the saw blade is exactly adjusted to 90°to the machine table (see fig.
1). The blade must also be exactly adjusted to 90°to the fence (see fig. 2).
Discrepancies arising from these cuts will result in gaps in the finished joints.

Machine Description
PICTURE D-2:
The MORSØ-NFX is constructed as a compact machine with a sturdy frame (1) with built in
lever system (2).
The cutting assembly is situated at the top of the machine.
In the slide frame (3), fitted at the cross (4), the knife block (5) is moved up and down. The
cross (4) runs in the guidings of the table.
The knives (6) fitted on the knife block (5) cut not only the notch but also cope the corners to
complete the joint.
The forward movement of the knife block (5) is made manually.
PICTURE D-2.1
The stile is placed on the table (7) against the fixed fences (8). The setting of the adjustable
fence (9) to the width of the stile is made by pushing this fence (9) towards the fixed fences
(8) until there is a distance of about 5 mm between the stile and the fixed fences (8).
PICTURE D-2:
The cock-bead stops (10) are adjusted to the required cutting depth of the notch.
The adjustment of the sliding longitudinal stops (11) is done by means of a template of the
stile.
MORSØ-NLFX can be fitted with nose knives from 12 to 26 mm.
MORSØ-NSFX can be fitted with nose knives from 6 to 20 mm.

In General
The machine is delivered ready for use and complete with standard equipment.
Only the table extensions (18) and fences (8) are dismounted during transport.
NOTE before starting up first time:
1. The lever clamp on the arc is loosened (it functions as the rear stop when moving the
knife block backwards).
2. The knife block is moved halfway back, and the waste chute is fitted.
Place the machine 1 m from the wall as stated in D-1. The machine can be fastened to the
floor using parabolts through the two holes in the bottom of the machine frame.
Check each time before starting that all protection devices are correctly fitted.
Fitting the Table Extensions and fences
(the drawing shows the left side, the same procedure is used on the right side).
Before fitting, the ends of the table extension (18) and the table (7) must be cleaned
thoroughly. Special attention must be paid to the pin and screw holes, as the smallest
amount of dirt will prevent the correct alignment.
A
fter cleaning, the table extension is pressed against the table so that the pins placed in the
table extension are inserted in the pin holes in the table. The included bolt is now inserted
into the hole and fastened with a standard spanner.
The fence (8) is fitted on the table extension (location pins are fitted in the table extension). It
is secured with allen screws.
(Extra extension tables and supporting legs can be ordered as accessories).

Adjustment of the cock-bead stops (10)
The cock-bead stops (10) are adjusted as follows:
1. Loosen the Allen screws on the cock-bead stops (10) and move these to rear of the
sliding guide.
2. Using a test piece (a) make a notch cut into the cock-bead. This cut must be the same
depth as the cock-bead. The overall width must be equal to the width of the centre cross-
rail. When you are satisfied the two sizes are equal, we can now position and lock the
cock-bead stops (10).
3. Press the foot-pedal down and hold it in this position. By operating the hand lever, bring
the knife block (5) forward into the previously cut notch. Position the cock-bead stops (10)
against the cock-bead and lock them in place using the Allen screws. When these stops
are fixed in position the knife block (5) can only cut into the cock-bead as far as this
setting. The notch cut depth is then referenced from the face of the cock-bead. The width
of stile can vary without changing this setting.
4. Check the alignment of the two cock-bead stops (10) using a straight edge. By bringing
the knife block (5) forward, check that they are level and true with the fence.
5. Lock the second Allen screws on the cock-bead stops (10).
6. This setting will allow you to make regularly accurate notch cuts in the stiles. These stops
will need no further adjustment unless the size of the cock-bead changes.
