1.4 Obligation and liability
The 43/6 S Stitching Head has been built according to state-of-the art technology under
observance of all the recognised safety regulations. However, dangers to life and limb of the user
or third parties and damage to the system or other material assets can still occur during use.
The stitching head should only be used,
• for the purpose for which it was designed
• when it is in a perfect technical condition.
Faults which could reduce levels of safety when using the machine must be eliminated
immediately.
Warranties and liability on the part of the manufacturer are fundamentally covered by the
regulations laid down in our ”General sales and delivery conditions”.
Warranty claims will only be valid if the number label is affixed
(number label on stitching head housing).
1.5 Correct use
The Stitching Head 43/6 S is designed exclusively for binding brochures and leaflets or similar
items.
Any use of the machine contrary to that described above is forbidden, since incorrect use of the
machine can present a danger.
1.6 Organisational measures
The user of machine is required to provide the required personal safety equipment. All existing
safety devices should be checked regularly.
1.7 Safety and protective devices
All safety and protective devices must be correctly attached to the machine and should be in full
working order before every start-up of the machine and Stitching Head 43/6 S.
Safety and protective devices may only be removed:
• After the machine has come to a standstill and
• As security against the machine starting up again.
1.8 Non-formal safety measures
The Operating Manual must be kept so that it is permanently at hand at the machine with
Stitching Head 43/6 S. There are also generally valid local regulations concerning accident
prevention and environmental protection measures which should be made available and observed
in addition to those described in the Operating Instructions.
All safety and danger signs on the machine should be maintained in a legible condition and should
be renewed where necessary.

1.10 Parts of the equipment which are particularly dangerous
There is a risk of injury in the area of moving parts of the stitching head.
1.11 Maintenance and repair work, elimination of faults
Undertake the required setting, servicing and inspection work on schedule.
The machine may only be operated in cycle mode during all servicing, inspection and repair work
on the Stitching Head 43/6 S.
Always make absolutely sure that the machine is only being operated by one person in order
to avoid any influence to the machine by any other persons.
1.12 Structural modifications to the stitching head
Changes to the stitching head, additions or modifications may only be undertaken with the
manufacturer's permission.
1.13 Cleaning the machine and the disposal of waste products
The functionality of the stitching head and perfect processing of the product can only be
guaranteed over a prolonged period of time if the stitching head is regularly cleaned and
maintained in accordance with the standard methods of mechanical engineering.
In this regard, particular attention should be paid to the regular removal of trimmed paper
residue and paper dust, as these can result in jamming of the stitching head or increased
wear.
Substances and materials used (e.g. solvents and lubricants) must be handled correctly and
disposed of in an environmentally friendly manner.

3.1 Installation of the stitching head
3.1.1 Clamping the stitching head
- Fig. 4 -
The stitching head is held by a tenon block which is inserted into the stitching head mounting on
the machine.
- Unscrew tenon block from the stitching head with Allen key SW4 e.
- Introduce tenon block laterally into the stitching head mounting b.
- Insert stitching head into stitching head mounting, so that the driver lug c can be inserted into
the stroke bar d and the tenon block fits into the stitching head.
- Fix the stitching head by tightening the tenon block in the stitching head mounting using the Allen
key e.
3.1.1.1 Lateral adjustment of the stitching head
- Fig. 4, Fig. 5 -
The center of the wire formed parts within the stitching head must be set to the desired stitching
position for the wire stitch by lateral adjustment.
- Loosen the tenon block a with the Allen key e.
- Move the stitching head sideways, until the desired position is reached.
- Fix the tenon block in the stitching head mounting b with the Allen key.
3.1.1.2 Front adjustment of the stitching head
- Fig. 5 -
The lifting movement of the wire formed parts must drive the stitch accurately into the clincher box
forming gap. (Cf. Chap. 3.1.4). If the center of the wire stitch is located too far in front of or behind
the clincher box, or if the lifting movement is not precisely aligned with the clincher box, this can be
corrected by adjusting the set screws f on the stitching head.
- Remove stitching head.
- Adjust set screws f.
- Fit stitching head.
