Foreword

This instruction manual is intended to help the user to become familiar with the machine and take advantage of its application possibilities in accordance with the recommendations.

The instruction m anual contains important information on how to operate the m achine securely, properly and ec on om i cally. Observation of the instructions eliminates danger, reduces costs for repair and down-times, and increases the reliability and life of the machine.

The instruction manual is intended to complement existing national accid ent prevention and environm ent protection regulations.

The instructio n m anual must always be available at the machine/sewing unit.

The instruction ma n ual must be read and ap pli ed by any pers on that is authorized to work on t he m achine/sewi ng unit. This means:

–

Operation, includi ng equipping, troubleshooting during the work cycle, removing of fabric waste,

–

Service (maintenance, inspection, repair and/or

–

Transport.

The user also has to assure that only authorized personnel work on the machine.

The user is obliged to check the mac hi ne at least once per shift for appare nt damages and to imme di a t l y report any changes (including the performance in service), which impair the safety.

The user company must ensure that the machine is only operated in perfec t working order.

Neve r re mo ve or disabl e any safety devices. If safety devices need to be removed for equippi ng, repairing or

maintaining, the safety devices must be remounted directly after completion of the maintena nce and repair work.

Unauthorized modification of the machine rules out liability of the manufacturer for damage resulting from this.

Observe all safety and danger recommendations on the machine/unit! The yellow-and-black striped surfaces designate permanend danger areas, eg danger of squashing, cutting, shearing or collision.

Besides the recommendations in this instruction manual also observe the general safety and accident prevention regulations!

General safety instructions

The non-observance of the following safety instructions can cause bodily injuries or damages to the machine.

3. The machine mus t be used only for th e pu rpos e i ntended. Use of the machine without the safety devices is not permitted. Observe all the r e levant safety regulations.

4. When gauge parts are exchanged (e.g. needle, presser foot, needle plate, feed dog and bobbin) when threading, when the workplac e i s left, and during service work, the machine must be disconnected from the mains by switching off the master switch or disconnecting the mains plug.

5. Daily servi cing work must be carried out onl y by appr opriately trained persons.

6. Repairs, conversion and sp ecial maintenance work must only be carried out by technicians or persons with appropriate training.

7. For service or rep ai r work on pneumatic systems, disco nn ect the machine fr om the compressed air supply system (max. 7-10 bar). Before disconnecting, reduce the pressure of the maintena nce unit. Exceptions to this ar e only adjustments and functions checks made by appropriately t r ained technici an s.

8. Work on the el ectrical equipme nt must be carried ou t only by elect ricians or appropriately t r ained persons.

9. Work on parts and systems under electric current is not permitted, except as specified in regulations DIN VDE 0105.

10. Conversion or changes to the machin e m ust be authorize d by us and made only in adherence to all safety regulations.

11. For repairs, only repl acement parts approved by us mu st be used.

Basic type

Single-needle double-lockstitch machine with underfeed, differentiable-foot overfeed and thread cutter for light to medium-heavy material with 4-mm stitch length and max. 8-mm overfeed length.

generally made of textile fibers, but it may also be leather. It is used in the clothing and domestic-upholstery industries.

This sewing machine can also be used to produce so-called technical seams. In this case, however, the operator must assess the possible dangers which may arise (with which the one hand relatively unusual and, on the other, they are so varied that no single s et of criteria can cover them all. The outcome of this assessment may require appropriate safety measures to be taken.

Generally only dry material may be sewn with this machine. The material may be no thicker than 6 mm when compressed by the lowered sewing feet. The material may not contain any hard objects, since if it does the machine may not be operated without an eye-protection device. No such device is currently available.

The seam is generally produced with textile-fibre sewing thread of gauge up to 30/2 Nm (synthetic yarn) or 30/3 Nm (covering yarn). Before using any other thread the possible dangers arising must be assessed and appropriate safety measures taken if necessary.

This special sewing machine may be set up and operated only in dry, well-maintained premises. If the sewing machine is used in other premises which are not dry and well-maintained it may be necessary to take further precautions (which should be agreed in advance - see EN 60204-31: 1999).

As manufacturers of industrial sewing machines we proceed on the assumption that personnel who work on our products will have received training at least sufficient to acquaint them with all normal operations and with any hazards which these may involve.
