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 instruc ti o n m an ual contains i m po rt a nt i nf ormation on how t o 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 instruc ti o n m an ual must alway s 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, i ncl u di n g e qu i pp i ng , troubleshoot i ng du r ing 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 o bl i g ed to c he c k th e machine at lea s t o nc e pe r shi f t f or apparent da ma ge s and to immedia tl y r e po r t a ny c h an ge s ( i ncl u di n g the performanc e i n se r vi c e), wh i c h impair the safety.

The user comp an y mu s t e ns u r e t ha t t he ma c hi n e i s only operated i n perfect working order.

Never remove or disable any safety devices.

If safety dev i c e s ne ed to be removed for equi pp i ng , r e pa i ri ng 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 manufacture r fo r da ma ge res u l ti n g f r om th i s .

Observe all safety and danger recommendations on the machine/unit! The yellow -and-black str i pe d surfaces desig na t e pe rma ne nd danger areas, eg danger of squashing, cutting, shearing or collision.

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.

1. General notes

The service instructions on hand describe the adjustment of the automatic bartacker 510.

ATTENTION !

The operations described in the service instructions may only be carried out by qualified staff or other appropriately trained persons!

Caution: Danger of injury !

In case of repair, alteration and maintenance work switch off main switch.

Carry out adjusting operations and functional tests of the running machine only under observation of all safety measures and with utmost caution.

These service instructions describe the adjustment of the automatic bartacker in a logical order. Please observe in this connection that various setting positions are interdependent. The adjustment process must therefore be carried out int the order given.

For all setting operations of parts involved in the stitch formation a new needle without any damage has to be inserted.

2. Arm shaft

Remove mechanism

–

Unscrew arm cover.

–

Loosen screw 4 at the thread trimmer magnet.

–

Unscrew screws 2 and 5 and take off thread trimming mechanism 3.

Mount mechanism

–

Push thread trimming mechanism 3 on the magnet and place it on the machine head.

–

Insert screws 2 and 5 and screw tight.

–

Tighten screw 4 at the thread trimmer magnet.

–

2.2 Assembly of the crank

Caution: Danger of injury !

Switch off main switch.

Remove and mount crank only when the automatic bartacker is switched off.

Standard

The crank 4 has to be mounted on the arm shaft 1 in such a way that the pivot 3 of the screw 2 reaches into the drill-hole on the arm shaft. The screw 2 is the first screw in the direction of rotation.

Assembly

–

Push crank 4 on arm shaft 1.

–

Twist crank 4 in such a way that its first drill-hole in the direction of rotation lies above the drill-hole in the arm shaft 1. Insert screw 2 with pivot 3 and screw tight.

–

Insert screw 5 and tighten.

2.3 Arm shaft position

Caution: Danger of injury !

Switch off main switch.

Check and adjust position of the arm shaft only when the automatic bartacker is switched off.

Standard checking

The arm shaft 1 should have no axial backlash, but it must not move too heavy.

–

Check the arm shaft with regard to axial backlash and rough running.

Correction

2.5 Adjust bobbin winder

Caution: Danger of injury!

Switch off main switch.

Check and adjust bobbin winder only when the automatic bartacker is switched off.

Standard

The bobbin winding operation must stop automatically when the bobbin is filled up to approx. 0.3 mm below the edge of the bobbin.

Correction of the bobbin winder wheel

–

Loosen screws at the driver wheel 1.

–

Shift driver wheel 1 axially in such a way that it abuts on the bobbin winder wheel 2 with the bobbin cover screwed on .

–

Tighten screws at the driver wheel 1. The second screw in the direction of rotation is located at a spot-faced place.

–

Put on head cover and tighten.

–

Check bobbin winder and repeat adjustment, if necessary.

Correction of the bobbin capacity

–

Loosen screw 3.

–

Adjust bobbin winder clip 4.

–

Tighten screw 3.

Note:

When correcting the driver wheel take care that the oil wicks do not collide with the driver wheel afterwards.

2.6 Thread trimmer cam

Caution: Danger of injury!

Switch off main switch.

Check and adjust thread trimmer cam only when the automatic bartacker is switched off.

Standard checking

The correct position of the thread trimmer cam 1 is marked by a point on the upper shaft 2 and a line on the thread trimmer cam 1.

The position is correct when both markings are standing opposite. –

Engage handwheel and turn until the marking points 4 and 5 on the upper shaft and the thread trimmer cam are visible.

–

Check whether both markings are standing exactly opposite.

Correction

–

Loosen screws 3 at the thread trimmer cam.
