SAFETY RULES
The sewing machines described in this instruction manual are prohibited from being put into service until it has been
ascertained that the sewing units, in which these sewing machines will be built-in have conformed with the EC Council
Directives (89/392/EEC, Annex II B).
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 instruction from the motor supplier.
2 . Observe the national safety rules valid for your country.
3 . 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.
4 . 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.
5 . Wear safety glasses.
6 . In case of machine conversions and changes all valid safety rules must be considered. Conversions and changes are made
at your own risk.
7 . The warning hints in the instructions are marked with one of these two symbols:
8 . For 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 For threading needle(s), looper, spreader etc.
8. 2 For replacing sewing parts such as needle, 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 For maintenance work.
8. 5 When using clutch motors without actuation lock, wait until the motor is stopped totally.
9 . Maintenance, repair and conversion work (see item 8) must be done only by trained technicians or special skilled personnel
under consideration of the instructions.
10 . Any work on the electrical equipment must be done by an electrician or under direction and supervision of special skilled
personnel.
11 . Work on parts and equipment under electrical tension is not permitted. Permissible exceptions are described in the
applicable sections of standard sheet DIN VDE 0105.
12 . 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 (e.g.
pneumatic equipment with air tank), the pressure has to be removed by bleeding.
* Exceptions are only allowed for adjusting work and function checks done by special skilled personnel.

ILLUSTRATIONS
This manual has been arranged to simplify ordering repair parts. Exploded views of various sections of the
mechanism are shown so that the parts may be seen in their actual position in the machine. On the page opposite
the illustration will be found a listing of the parts with their part numbers, description and the number of pieces
required in the particular view being shown.
Numbers in the first column are reference numbers only, and merely indicate the position of the part in the
illustration. The reference number should never be used in ordering parts. Always use the part number listed in
the second column.
Component parts of sub-assemblies which can be furnished for repairs are indicated by indenting their descriptions
under the description of the main sub-assembly. As an example refer to the following text.
9. 29126EC Upper Looper Drive Shaft Assembly ........................................ 1
10. 22503F Screw ............................................................................. 1
11. 39543E Cam Follower Locking Clamp ............................................. 1
When a part is common to all machines covered in this manual, no specific usage will be mentioned in the description.
However, when the parts for the various machines are not the same, the specific usage will be mentioned in the
description and, if necessary, the difference will be shown in the illustration.
A numerical index of all the parts shown in this manual is located at the back. This will facilitate locating the
illustration and description when only a part number is known.
IDENTIFYING PARTS
Where the construction permits, each part is stamped with its part number. On some of the smaller parts and on
those where construction does not permit, an identification letter is stamped in, to distinguish the part from similar
ones.
PLEASE NOTE: Part numbers represent the same part, regardless of which manual they appear in. On all orders
please include part number, name and style of machine for which the part was ordered.
* For optimum performance, use only genuine Union Special replacement parts.
