SAFETY RULES

1. Before putting the machines described in this manual into service, carefully read the instructions. The starting of each machine is only permitted after taking notice of the instructions and by qualified operators.

IMPORTANT! Before putting the machine into service, also read the safety rules and instructions from the motor supplier.

1. Observe the national safety rules valid for your country.

2. The sewing machines described in this instruction manual are prohibited from being put into service until it has been ascertained that the sewing units which these sewing machines will be built into, have conformed with the EC Council Directives (89/392/EEC, Annex II B).

Each machine is only allowed to be used as foreseen. The foreseen use of the particular machine is described in paragraph "STYLES OF MACHINES" of this instruction manual. Another use, going beyond the description, is not as foreseen.

1. All safety devices must be in position when the machine is ready for work or in operation. Operation of the machine without the appertaining safety devices is prohibited.

2. Wear safety glasses.

3. In case of machine conversions and changes all valid safety rules must be considered. Conversions and changes are made at your own risk.

4. The warning hints in the instructions are marked with one of these two symbols:

1. When doing the following the machine has to be disconnected from the power supply by turning off the main switch or by pulling out the main plug:

8.1 When threading needle(s), looper, spreader etc.
8.2 When replacing any parts such as needle(s), presser foot, throat plate, looper, spreader, feed dog, needle guard, folder, fabric guide etc.
8.3 When leaving the workplace and when the workplace is unattended.
8.4 When doing maintenance work.
8.5 When using clutch motors without actuation lock, wait until the motor is stopped totally.

1. Maintenance, repair and conversion work (see item 8) must be done only by trained technicians or special skilled personnel under consideration of the instructions.

2. Any work on the electrical equipment must be done by an electrician or under direction and supervision of special skilled personnel.

3. Work on parts and equipment under electrical power is not permitted. Permissible exceptions are described in the applicable sections of standard sheet DIN VDE 0105.
4. Before doing maintenance and repair work on the pneumatic equipment, the machine has to be disconnected from the compressed air supply. In case of existing residual air pressure after disconnecting from compressed air supply (i.e. pneumatic equipment with air tank), the pressure has to be removed by bleeding.

TENSION RELEASE (UNDERBED THREAD TRIMMER)

Set separators (C) as close to tension discs (D) without touching them and not to bind when fully extended.

Tension discs (D) must open as soon as cutting process begins.

Tension disc separators (C) should move freely between tension discs (D) without binding.

Thread trimmer and tension release assemblies are linked together.

FIG 9

TO ADJUST:

Loosen screw (E).

Turn eccentric (F), located behind screw (E) to set tension release lever (B) as required.

Retighten screw (E).

After adjustment there should be no binding at any point.

Adjust the tension release lever (A, fig. 9) to fully open the tension release and return without binding. The tension release is timed with the activation of the fabric thread trimmer.

THREAD PULL-OFF

Pull-off hooks (B) for needle threads, control length of needle thread tails on a garment after trimming.

Set hooks (B) to strike-off shortest tail possible and still start sewing within the first or second stitch.

Set thread pull-off hook (C), for spreader thread so that thread is clamped securely when trimmed and starts properly when the stitch is first started. Lowering the needle thread pull off hooks will strike off more thread leaving longer tails.

Set hook (D), for the looper thread so that the thread is clamped securely when trimmed.

NOTE: Moving strike-off hooks down strikes off more thread. Moving strike-off hooks up strikes off less thread.
