2 Safety
This section contains basic instructions for your safety. Read the instruc-
tions carefully before setting up or operating the machine. Make sure to
follow the information included in the safety instructions. Failure to do this
can result in serious injury and damage to the machine.
2.1 Basic safety instructions
The machine may only be used as described in these operating instructions.
The operating instructions must be available at the machine's location at
all times.
Work on live components and equipment is prohibited. Exceptions are de-
fined in the specifications in DIN VDE 0105.
For the following work, the machine must be disconnected from the power
supply using the main switch or by disconnecting the power plug:
• Replacing the needle or other sewing tools
• Leaving the workplace
• Performing maintenance work and repairs
• Threading
Missing or faulty spare parts could impair safety and damage the machine.
Therefore only use original spare parts from the manufacturer.
Transportation Use a lifting carriage or forklift to transport the machine. Raise the ma-
chine max. 20 mm and secure it against slipping off.
Set-up The connecting cable must have a power plug approved in the specific
country. The power plug may only be connected to the power cable by a
qualified specialist.
Operator's obliga-
tions Observe the country-specific safety and accident prevention regulations
and the legal regulations concerning industrial safety and the protection of
the environment.
All warnings and safety signs on the machine must always be in legible
condition and may not be removed. Missing or damaged labels must be
replaced immediately.

3 Work fundamentals
3.1 Symbols in the text
The following symbols in the margin and in the text indicate the type of in-
formation contained in the text.
Correct setting
Indicates the correct setting.
Faults
Indicates faults that can occur due to an incorrect setting.
Cover
Indicates which covers must be removed in order to access the compo-
nents to be set.
Steps to be performed for servicing, maintenance and installation
Steps to be performed via the software control panel
The individual steps are numbered:
1. First setting step
2. Second setting step
3. Third setting step, etc.
The sequence of setting steps must always be followed.
Result of performing an operation
If, as a result of a setting step, a change occurs in the machine or a new
message appears on the display which is important feedback for you, this
change is marked with an arrow: 
Important
Indicates that special attention must be paid to this point when performing
a step.
Information
Provides additional information.

3.2 Sequence of settings
Comply with the
sequence Always comply with the sequence of individual setting steps as specified.
It is absolutely essential that you comply with all notices regarding prereq-
uisites and subsequent settings that are marked with in the margin.
3.3 Cable guidance
Joining cables Ensure that all cables are laid in the machine such that the function of
moving parts is not hampered.
1. Lay cables that are too long in tidy loops.
2. Bind together the cable loops with cable ties.
Tie loops wherever possible to fixed parts. The cables must be secured
firmly.
3. Cut off the extending ends of cable ties.
3.4 Screws in safety covers
Screws in safety covers need not be removed from the screw hole. As
soon as the screws are loosened such that the cover can be detached,
you can remove the cover. The screws remain either in the housing or in
the cover. In the text, such screws are marked with the addition (safety
cover).
Machine damage possible due to using the incorrect sequence.
It is essential that you comply with the sequence of work steps specified
in these instructions.
NOTE
Machine damage and function disruptions are possible due to in-
correctly laid cables.
Excess cables can impair the functioning of moving machine parts. This
impairs the sewing function and can result in damage.
Excess cable should therefore be laid as described above.
NOTE
