PUTTING INTO OPERATION

For safety during transportation, the moving parts of your CS 88 – 89 have been blocked : these are the Top Presser Bracket (or Plunger) / Sliding Table / Horizontal (rebate) Clamp.

For the explanations given in this manual, the operator must be standing at the back of the machine, keeping the machine slightly in his left. (See REFERENCE POSITION below). In this position, the operator is always in the same distance to the corner, regardless of the size of the frame.

Advice : to work frames of bigger sizes easily, you can put the CS 88-89 machines in front of your work bench (make sure that the work bench is not higher than the machine). The CS 88-89 machines have been conceived in a triangle form to fit any work bench : if you wish so, you can cut one of the corners of your work bench, to locate the machine in this corner. This way, while making big sized frames, you will not be using more than one of the corners of your work bench.

Position a moulding against the LEFT backfence.

Loosen the locking knob B.

Press the moulding against the table T, tilt the backfence so that it fits behind the moulding, then tighten knob B.

Position the second moulding on the

RIGHT backfence and repeat the operation.

SELECTION OF STAPLING POSITIONS

The CS 88 / 89 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.

2 mm MINIMUM (Approx.1/8’’)

2 mm MINIMUM (Approx.1/8’’)

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 .

Triangle top pressers are good for flat mouldings or for mouldings representing a flat or horizontal area to come down on. The round rubber ends are good for complicated forms (uphill, downhill or reverse mouldings).

For very tall mouldings the round rubber ends can be also inserted into the top presser bracket without their support to gain capacity in height.

ADJUSTMENT OF THE ASSEMBLY ANGLE

If several cutting machines are being used in your production or if you receive your mouldings 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 88 / CS 89 can be adapted to find precisely the cutting angle of your cutting machine.

If the corner is open towards outside, unscrew (turn anti-clockwise) the angle adjustment screw AS (see Fig 1 page 1) a little to correct the fault and check again.

Outside

Inside

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.

If you get this result, check your 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.

IT IS IMPOSSIBLE TO MAKE A RECTANGLE

FRAME WITH ANGLES SMALLER THAN 90°.

USE

MEANS OF ASSEMBLY

The joining is performed by using metal wedges, a Cassese invention, designed to ensure very tight corners. Five sizes are available : 5, 7, 10,

12 and 15 mm. They come in throw-away cartridges that are colourcoded 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 88 / CS 89 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 88 / CS 89, only use genuine CASSESE cartridge wedges.

Beware of counterfeit products.

SETTING UP THE WEDGE CARTRIDGE

Move the sliding table forwards to allow access to the cartridge. (1)

Pull the positioning cord back, using the ball as a grip. (2)

Push the cartridge fully home in the distributor slot. (3)

Release the wedge pusher cord carefully to avoid damaging the pusher and spring.

Note: For easier changing of the wedge magazine during operation, the wedge cartridge can be accessed by lifting the sliding table from the rear with the finger.

UNDERPINNING THE FRAME

The stapling points are defined (see Defining the stapling point, page 5).

The joint angle has been checked (see Setting the joint angle, page 6).

The distance between the top of the moulding and the bottom of the top clamp is outside permissible maximum. (See Choice of top clamp, page 6).

Correct size wedges (normal wood or hard wood) have been loaded in the machine.

Position the first moulding against the right stop and slide it up to the left stop.

Keeping the first moulding secure, position the second moulding against the left stop, then slide it into contact with the first moulding.

Position the rebate clamp:

Unscrew the knob of the top clamp, then move the top clamp against the 2 mouldings, without forcing. Lock the top clamp knob again, without pushing it. Clearance of around 1 mm is left to make it easier to move the mouldings during assembly.

Move the sliding table forwards or backwards to stop P2 or P1 (page 5).

Then:

CS 88

Keeping the mouldings secure, slowly push down the pedal.

When the top clamp comes into contact with the moulding, speed up the movement so that the wedge is inserted more easily.

To stack wedges*

- Release the pedal until the top clamp begins to lift.

- Push the pedal down again.

* When stacking wedges, the sliding table should be locked in place.

CS 89

Keeping the moulding secure, gently push the pedal so that the two mouldings are secured by the rebate clamp.

Then press the pedal down fully to insert the wedge.

If there is a second stapling position, keep your foot pressing down on the pedal, move the sliding table to the second position, raise your foot slightly then push fully down to insert the second wedge.

Then release the pedal completely.

Note: If several wedges are inserted, raise your foot slightly to keep horizontal pressure on the mouldings, then push fully down: the second wedge is inserted and pushes the first wedge further in.

MAINTENANCE

1) LUBRICATION

Periodically, remove the wedge distributor (Fig 1, block H) and clean it (by air gun) without dismounting 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,

- Close the air valve.

- 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 following section (3).

PROCEDURE

- 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, unscrew the two central screws (GF1, GF2) that hold the fixed (square) guide of Block H in place. Use for this the smaller (2.5mm) Allen key supplied with the machine. Remove the fixed guide completely to free the old hammer. If still not possible to get rid of the old hammer, remove the four screws (A, B, C, D) and open the block H.

(Two factory set locator pins E & F allow the plates to be re-positioned precisely again.)

- Remove the old hammer. Assemble the Block H back 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 or with a ruler that the block H does 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.

If you have any difficulty to remove the block H from the machine, push down with your hands the top presser’s bracket arm.This should free the block H that is stuck with the hammer.
