INTRODUCTION
You have just bought a CS 79 frame joining machine, so we congratulate on your sensible
choice and thank you for your trust in Cassese products.
The CS 79 benefits from the experience of the joining machines that brought Cassese a cer-
tain reputation. It makes it possible to join wooden mouldings of all profiles ( patent n°
7522814).
The CS 79 is designed to allow the operator to move all around the machine.
The joining operation is carried out by using metal wedges especially designed to perform
a tight join. These wedges come in throw-away plastic cartridges, without glue, individu-
ally lubricated and rust-protected for the toughest challenges.
IMPORTANT : You should not use other wedge cartridges than those manufactured by
Cassese and marketed by official Cassese distributors (registered mark CS).
BEWARE OF COPIES.

As a general rule a MINIMUM 2 mm clearance (less than 1/8”) above the wedges shall
be respected.
Same sized wedges can be stacked in order to avoid to have to change the cartridge size
when joining frames with different thickness.
AS A GENERAL RULE, THE JOINING MUST BE CARRIED OUT AS
CLOSE TO THE THICKEST MOULDING PART(S) AS POSSIBLE .
SELECTION OF STAPLING POSITIONS
The CS 79 is designed to join mouldings in one or two places (positions) without limitation of the
number of wedges in any of those places. The selection depends on the width and thickness of the
moulding to join.
SETTING AND STORING THE STAPLING POSITIONS

Standing in the work position used of reference for explanations (behind the machine; see
Fig 2, page 1), with your left hand, put the first moulding chop in front of the left (1st)
backfence B1 and bring the chop in contact
with the right (2nd) backfence B2.
For the stapling position close to the inside
of the frame :
Move the 90° joining angle backwards, until
you have reached the furthest
position to the inside of the frame where you
want to insert wedge(s).
Then bring the lever P1 against the limit stop
B and tighten the lever.
Now the two positions of joining are set and
the machine’s 90° angle can move only
within the limits of these two positions.
In case you would like to insert wedges in between these two positions, or if you are
working with a very small moulding and would like to insert wedges only in one place, you
can use the lever P3 located on the limit stop B.
This intermediate lever P3 also enables you to stack wedges (on top of each other in the
same position) without risk of missing the stacking operation (not pushing the first wedge
deeper inside).
For the stapling position close
to the outside of the frame :
Move forward the 90° joining angle assembly
Euntil the place where you want to insert the
wedge(s) has been reached by the WEDGE
EXIT (see picture). Then bring the lever P2
against the limit stop Band tighten it.

The triangle top pressers with their extra long
support that are included with your CS 79 gives
you the capacity to work mouldings up to 35 mm
(1 3/8”) high. For taller mouldings there are other top
pressers available from your regular source of Cassese
products. See on page 2, the list of other top pressers
for your CS 79 and the capacity in height of moulding
they would allow you to join.
If the corner is open towards outside, unscrew (turn anti-clockwise) the angle adjustment
screwAS (see Fig 1 page 1) a little to correct the fault and check again.
ADJUSTMENT OF THE ASSEMBLY ANGLE
If several cutting machines are being used in your production or if you receive your mould-
ings already cut by your suppliers (chop service), the angles of the mouldings will be slightly
different from one cutting machine to the other. The joining angle of your CS 79 can be
adapted to find precisely the cutting angle of your cutting machine.
If the corner is open towards inside, screw in (turn clock-wise) the angle adjustment screw
AS (Fig 1 page 1) to correct the fault.
Ifyou get thisresult, checkyour cutting angle,which is wrong
in this case because it is less than 45°.
Carry out the adjustment of the angle of your cutting
machine.

Make sure that the distance between the moulding’s top and
the presser’s bottom is not more than 30 mm (1 ¼”).
If the distance is bigger than this, use another (longer) top
presser to reduce the distance.

SELECTION OF A TOP PRESSER END (See page 12 : NEW VERSION TOP PRESSER)
Triangle top pressers are good for flat mouldings or for mouldings presenting a flat or horizontal
area to come down on. The green or orange rubber ends are good for complicated forms (uphill,
downhill or reverse mouldings).

JOINING THE FRAME
USE
LOADING AND CHANGING THE WEDGE CARTRIDGE ON MACHINE
Pull the wire with ball of the wedge pusher spring F (fig.2, p1) fully out.
If there is a cartridge on machine, holding the wire pulled out, remove it by simply sliding out
the cartridge.
Holding the wire pulled out, put a new cartridge on machine and pay attention that it is fully
inserted in the wedge distributor’s window.
Release gently the wire with ball of the wedge pusher spring F.
The joining is performed by using metal wedges, a Cassese inven-
tion, designed to ensure very tight corners. Seven sizes are available :
3, 4, 5, 7, 10, 12 and 15 mm. They come in throw-away cartridges
that are colour-coded per size for easy identification. Cartridge
wedges exist in two versions : NORMAL for soft and normal timbers
and HW for very hard timbers. These hardwood wedges are to be
used only on hardwoods.Your CS 79 machine is designed to use all sizes
of Cassese cartridges without having to change any parts on the machine
or having to adjust anything.
For the long term performance and reliability of your CS 79, only use
genuine CASSESE cartridge wedges. Beware of counterfeit products.
MEANS OF ASSEMBLY
After selecting and setting the stapling positions (page 5 & 6), adjusting the assembly angle
(page 7), checking the distance between the top presser and the moulding (page 7) and loading
the best suited type (normal or hardwood) and size of wedges (page 8),
1- Put the first (left-hand) moulding in front of the fence B1 and push it so that its mitre end
reaches the other fence B2.
2- Holding it so, put the second moulding chop against fence B2 and slide it until it reaches the
first moulding.
3- Holding the mouldings in place against each other, hold the backfences B1 & B2 with your
thumbs and make the angle assembly slide backwards until the lever P1 reaches the limit stop B.
You can eventually tighten the intermediate lever P3 to be sure that the position remains fixed.
4- Still holding the mouldings well profiled against each other, push the foot pedal P (Fig 2, p.1)
until the green light V (Fig 1 p1) comes on that indicates that the wedge has been fully inserted. If
you intend to stack a second (or third) wedge in the same position, just push the footpedal again
until V-light comes on. In this case using (tightening) the lever P3 will enable you to stack them
more easily.
5- If there is a second stapling position chosen (with lever P2), just repeat the same operation by
pushing forward the mouldings and the angle assembly of the machine until P2 reaches the limit
stop B. And repeat step 4 above.

1) LUBRICATION
Periodically, remove the wedge distributor (Fig 1, block H) and clean it (by air gun) without dis-
mounting it.
It is recommended to lubricate the hammer (driver blade) periodically. To do so, remove the wedge
distributor (blockH) and put a small quantity of grease in the bottom hole of the wedge distributor.
The hammer will be lubricated every time it crosses the wedge distributor.
2) CLEARING OF A WEDGE STUCK IN THE WEDGE DISTRIBUTOR
If you push the foot pedal half way and release, a wedge may be half engaged in the wedge
distributor. In this case,
- Try to remove the cartridge that is in position. If it resists, use the wedge removal tool to push
down the wedge back in the cartridge.
- Pay attention not to make penetrate the tool more than 6mm (¼”) into the wedge distributor.
It is important not to leave a wedge half engaged in the wedge distributor, as it may cause the
insertion of two wedges when you join the next corner or may cause the jamming of the
hammer (the driver blade) in the wedge distributor.
- In case of the hammer (driver blade) jamming with a wedge in the wedge distributor, see the fol-
lowing section (3).

- Remove the cartridge that is on machine, and the top presser.
- Using the 3mm Allen key, loosen the locking screw of the wedge distributor Block H.
- Then lift the top presser’s bracket arm by hand. The wedge distributor will come out of its
housing.
- Remove it from the machine.
- The old hammer (wedge driver blade) is stuck in the wedge distributor : first try to remove it
with a pair of pliers. If not possible, remove the four screws (A, B, C, D) and open the block H.
(Two factory set locator pins E& Fallow the plates to be re-positioned precisely again.)
- Remove the old hammer. Assemble the Block Hback again.
Putting a new hammer (driver blade) :
- Put a drop of grease in the bottom hole of the wedge distributor (block H).
- Insert a new hammer into block H with the hole of the hammer downwards.
- Re-position the wedge distributor in its housing on the machine with the window towards the
cartridge.
- If the upper end of the hammer stays out of the block H, push it fully in with a piece of wood or
moulding.
While keeping the moulding in place (on block H) and pressing on it, pull up the top presser’s
bracket arm Po (Fig1 p1) with a quick movement.
The new hammer must have taken its position in the mechanism automatically.
- Check with your finger that the block Hdoes not stay out of the machine (higher than the work
level) and tighten the locking screw of block H. No need to tighten too much.
- The machine is ready to work again.

Cassese CS 79 FOOT OPERATED UNDERPINNER
NEW VERSION TOP PRESSER (item # Z6232)
This new version top presser comes now with
your CS 79 as a standard feature. Its height
can be adjusted with the pin so that the ma-
chine can work up to 78 mm (3”1/8) tall
mouldings.Payattentiontokeepalwaysmaxi-
mum 30mm (1”1/4) distance between the top
presser and the mouldings and to keep the
rubber triangle parallel to the 90° angle as-
sembly (backfences B1 & B2, Fig.1, p. 1)
The moulding height capacity of the
new triangle top presser support for
its 4 positions :
1) 37 mm (1”1/2)
2) 53 mm (2”1/8)
3) 68 mm (2”3/4)
4) 78 mm (3”1/8)
A similar adjustable support for the round rubber top pressers is now available with 3
positions for its height.
As the round rubbers are available in two lengths (30mm & 45mm) and in two hardness
finishes (orange for softwoods & green for very hardwoods), the maximum height of
moulding that this optional round rubber support can work in its three positions are :
Position hole # With short round rubber With long round rubber
1 37 mm (1”1/2) 22 mm (7/8”)
2 53 mm (2”1/8) 37 mm (1”1/2)
3 68 mm (2”3/4) 53 mm (2”1/8)
IMPORTANT :
In any position of the top presser, to insert wedges fully in, the distance between the
moulding and the down end of the top presser shall not exceed 30 mm (1”1/4).
If so, change the position of the top presser and bring it closer to mouldings.
