Fitting the AZ Hot Knife holder
The AZ Hot Knife attachment has been designed to accept the TC 20 Heated Knife and will need to be fitted with a Type 'T 013/45' blade.
A = Tighten to clamp Hot Knife into holder
B = Loosen to open up the base when fitting on to slideway
C = Rotate knob to adjust point at which the trigger switches the hot knife on
D = Sliding bearing adjustment screws.
A heatproof protective surface must be placed on the base of the machine under the fabric.
1 To fit the attachment to the slideway loosen screw B to create a gap in the base sufficient for it to be lowered onto the slideway.
Tighten screw B and check that the cutting head runs smoothly.
2 If the head is too loose or too tight when moved it can be adjusted, place the long end of the 2mm Allen key provided onto one of the four adjustment screws D and very gradually tighten it with one hand whilst moving the Cutting Head slowly with the other. Once you feel the sliding motion start to tighten undo the screw the smallest amount so the Cutting Head just slides easily.
Repeat this on the other screws in turn, two or three smaller adjustments on each screw may be needed to achieve an easy sliding movement with zero side play.
KC-AZ/2 7349-05/13
NOTE:
Once the sliding bearings have been adjusted the attachment should not need readjusting if the cutting head is removed and replaced at a later time. It is however, important that screw B is fully tightened each time the cutting head is fitted to the machine.

Fitting and use of the AZ HOT KNIFE
3 To fit the Hot Knife, simply insert it into the holder ensuring the Hot Knife is seated fully into its recess.
Tighten knob A and check Hot Knife is fully gripped in position, the blade should cut about 2-3mm (1/16” to 1/8”) away from the edge of the slideway.
4 Depress the Hot Knife and the trigger should switch the heat on prior to it coming into contact with the fabric.
The trigger can be adjusted to alter the position the heat is switched on by turning knob C.
5 Once the blade has reached the correct temperature press down to bring the blade in contact with the fabric and slide the cutting head to the right to seal and cut it.
A heatproof protective surface F must be placed on the base of the machine under the fabric.

Quick start
- Place a heatproof protective surface on the base of the machine under the fabric.
- Loosen screw B to open the base of the attachment, lower it onto the slideway and fully tighten screw B.
- If the head is loose or tight, adjust the four bearing screws D with the 2mm Allen key until it slides easily with zero side play.
- Insert the hot knife fully into its recess and tighten knob A; the blade should cut about 2-3mm (1/16" to 1/8") from the edge of the slideway.
- Check the trigger switches the heat on before the blade touches the fabric; to change the switch point, turn knob C.
- Once the blade is at temperature, press down onto the fabric and slide the cutting head to the right to seal and cut.
Troubleshooting
| Problem | Likely cause | Fix (from the manual) |
|---|---|---|
| Cutting head is too loose or too tight when moved | The sliding bearing adjustment screws (D) need adjusting. | Put the long end of the 2mm Allen key on one screw D. Tighten it very gradually while moving the head slowly. When the motion starts to tighten, back the screw off the smallest amount. Repeat on the other screws until the head slides easily with zero side play. Page 2 |
| Cutting head does not run smoothly after fitting | Screw B may not be fully tightened. | Tighten screw B fully and check that the head runs smoothly. It must be fully tightened each time the head is fitted. Page 2 |
| Hot knife heat comes on too early or too late | The trigger position needs adjusting. | Rotate knob C to change the point where the trigger switches the heat on. It should switch on before the knife touches the fabric. Page 3 |
| Hot knife is loose in the holder | The knife is not fully seated or knob A is loose. | Insert the knife fully into its recess. Tighten knob A and check the knife is fully gripped. Page 3 |
| Risk of damage to the machine base | Fabric is being cut without a heatproof surface. | Place a heatproof protective surface on the base of the machine under the fabric. Page 2 |
| Hot knife does not fit the holder | The wrong knife or blade is being used. | Use the TC 20 Heated Knife with a Type T 013/45 blade. Page 2 |
Frequently asked questions
Which heated knife and blade does this holder take?
It is designed for the AZ TC 20 heated knife fitted with a Type T 013/45 blade. See page 2.
Do I need to readjust the bearings each time I refit the head?
No. Once adjusted they should not need readjusting, but screw B must be fully tightened every time the head is fitted. See page 2.
How far from the slideway does the blade cut?
About 2-3mm (1/16" to 1/8") from the edge of the slideway. See page 3.
