1. 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,  top  roller,  needle  plate,  feed  dog  and  bobbin)  when  treading,  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 the machine must be disconnected from the compressed air supply system.

Exceptions  to  this  are  only  adjustments  and  function  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. Conversions  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.

It  is  absolutely  necessary  to  respect  the  safety  instructions  marked  by  these  signs.

Danger  of  bodily  injuries  !

Please  note  also  the  general  safety  instructions.

IMPORTANT    WARNING

In spite of all safety measures made on the machines, inappropriate actions of the operator may lead to dangerous situations. In

industrial  sewing  machines,  attention  should  be  paid  to  the  following  still  remaining  possible  sources  of  injury:

1. Moving  sewing  needle

- risk  of  injury  when  sewing  with  raised  pressure  foot  or  top  roller,  because  the  finger  guard  is  then  positioned  too  high,

- risk  of  injury  when  inadvertently  threading  down  of  the  motor  threadle.

2. Moving  thread  take-up  lever

- risk  of  injury  when  inadvertently  or  intentionally  inserting  the  finger(s)  between  the  thread  take-up  lever  and  its  guard.

3. Moving  pressure  member

- risk  of  injury  when  holding  sewn  work  in  immediate  vicinity  of  the  pressure  member  and  beginning  to  insert  under  the

pressure  member  a  considerably  thicker  sewn  work  portion,

- risk of injury when sinking the pressure member.

4. When switched off, the clutch motor slows down by inertia but would be reactivated by an accidental treading down of the

motor treadle. To avoid such risk, it is advised to hold the handwheel by hand and slightly to depress the motor treadle.

2. Introduction

This  service  book  contains  instruction  for  regulating  the  mechanisms  of  the  sewing  machine  head.
The instructions for use and for putting the machine into operation and for the control of the stopmotor are not included in this

service  book,  but  they  are  supplied  as  separate  publications.
This  service  book  is  universal  for  all  subclasses  of  the  machine  -  it  contains  setting  procedures  for  all  elements  which  may  be

placed on the machine of the given class. When the supplied subclass of this machine does not include some element, then it is

possible  to  leave  out  the  respective  parts  of  the  instructions.  The  optional  equipments  of  the  machine  and  the  respective

configurations  of  the  subclasses  of  the  machine  are  given  in  the  operating  instructions.
This sewing machine disposes of a large extent of its use. The machine should be set with respect to the parameters of the sewn

material,  the  sewing  thread  etc.  The  setting  for  the  individual  categories  is  given  in  the  chapter  10.2.
For  setting  the  machine,  simple  setting  aids  are  used  which  are  included  in  the  accessory  of  the  machine.  Besides  these  aids,

universal  measuring  devices  are  used,  such  as  slide  calliper,  feeler  gauges  and  dynamometer  for  measuring  the  thread  tension.
