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 manual contains important information on how to

operate the machine securely, properly and economically. 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

accident prevention and environment protection regulations.

The instruction manual must always be available at the machine/sewing

unit.

The instruction manual must be read and applied by any person that is

authorized to work on the machine/sewing unit. This means:

–Operation, including 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 machine at least once per shift for

apparent damages and to immediatly report any changes (including the

performance in service), which impair the safety.

The user company must ensure that the machine is only operated in

perfect working order.

Never remove or disable any safety devices.

If safety devices need to be removed for equipping, repairing or

maintaining, the safety devices must be remounted directly after

completion of the maintenance 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.

1. The machine must only be commissioned in full knowledge of the

instruction book and operated by persons with appropriate training.

2. Before putting into service also read the safety rules and

instructions of the motor supplier.

3. The machine must be used only for the purpose intended. Use of

the machine without the safety devices is not permitted. Observe all

the relevant safety regulations.

4. When gauge parts are exchanged (e.g. needle, presser foot, needle

plate, feed dog and bobbin) when threading, when the workplace is

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 servicing work must be carried out only by appropriately

trained persons.

6. Repairs, conversion and special maintenance work must only be

carried out by technicians or persons with appropriate training.

7. For service or repair work on pneumatic systems, disconnect the

machine from the compressed air supply system (max. 7-10 bar).

Before disconnecting, reduce the pressure of the maintenance unit.

Exceptions to this are only adjustments and functions checks made

by appropriately trained technicians.

8. Work on the electrical equipment must be carried out only by

electricians or appropriately trained 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 machine must be authorized by us

and made only in adherence to all safety regulations.

11. For repairs, only replacement parts approved by us must be used.

12. Commissioning of the sewing head is prohibited until such time as

the entire sewing unit is found to comply with EC directives.

13. The line cord should be equipped with a country-specific mains

plug. This work must be carried out by appropriately trained

technicians (see paragraph 8).

It is absolutely necessary to respect the safety

instructions marked by these signs.

Danger of bodily injuries !

Please note also the general safety instructions.

1. Product Description

1.1 Description of the Proper Use and Proper Application

The 506-3 is a robust, heavy-duty, curve-guided single needle

lockstitch short seam unit for seams of stitch type 301.

This short seam unit is designed for use in sewing heavy-weight fabric,

as well as thick and hard leather.

Thick and hard leathers find use in the sewing on of trim pieces, in the

sewing of buckle caps, tabs, suitcases, tarpaulins, knapsacks and

backpacks.

Heavy-weight fabrics are used in the sewing of heavy-duty carrying

belts, car belts, as well as belts for aviation.

Generally only dry sewing material may be worked with this machine.

The material may be no thicker than 16 mm when pressed together by

the lowered clamping feet.

The machine must be operated with eye protection. The information to

be found printed on the yellow sign on the head cover is to be strictly

adhered to.

The seam is generally made with synthetic sewing yarns with a

dimension of 30/3 to 8/3. Those wishing to use other threads must first

evaluate the dangers arising therefrom and, if necessary, take safety

measures.

This heavy short seam unit may only be installed and operated in dry

and clean areas. If the unit is used in other areas, which are not dry and

clean, further, to be agreed upon, measures may become necessary

(see EN 60204-31: 1999).

We, as manufacturer of industrial sewing machines, presume that the

operating personnel working on our products have been given

instruction so that all normal operations and the dangers possibly

arising therefrom can be assumed to be known.

1.2 Short Description

Uniform Quality

The unit always produces a uniform seam formation.

The high thread tension necessary for the working of heavy materials is

achieved through a hinged thread lever.

Direct Power Transmission

The power transmission from the motor to the arm shaft occurs via a

special V-belt. This results in a particularly strong perforating power for

the sewing of thick materials or multiple layers.

Interchangeable Curve Disks and Material Clamps

The different seam formations are determined by easily

interchangeable curve disks.

The material guidance occurs via a pattern curve with two guide curves.

The difficult and time-consuming turning of heavy pieces of material by

the seamstress is thus unnecessary.

The transmission of the movement to the material clamps occurs via

lever systems.

By changing the lever multiplication the seam formation sizes can be

varied within certain limits.

All curve disks belonging to a stitch number range are interchangeable

among each other.

Large Put-through Area and Large Placement Surface

The large put-through area allows the making of short seams far from

the edge of the material. A rolling-in of flexible sewing material is

possible. The closed width base plate offers a large placement surface

and simplifies the feed.

Pneumatic Clamp Opening

The stroke of the holder clamp is a maximum 20 mm. This stroke allows

the working of almost all sewable materials and leather thicknesses.

Electric Thread Burning Device

The thread separator device separates the needle and underthread by

burning immediately at the top edge of the material. The synthetic

threads are melted together at the ends. The thus created hardening

hinders a loosening of the seam and a unthreading of the needle thread.

Control Unit Quick DA104ED

The complete control of the sewing unit occurs via a Quick control unit.

It assumes the control tasks, monitors the sewing process and

indicates operator errors and malfunctions.

ATTENTION!

These operating instructions give the key functions and describe how

operator-level parameter values are changed by the operator.

For a detailed description of the control unit, please consult the enclosed

current issue of the operating manual of the motor manufacturer.
