sewing. The winder lever (4) stops winding automatically as
soon as the bobbin is full. The winder (6) always stops such
that the cutter (5) is at the proper position.
8. Pull off the full bobbin.
9. Clamp the thread behind the cutter (5) and tear it off.
Information
The hook thread can only wound on during sewing. The machine

4.7 Thread tension
Together with the hook thread tension, the needle thread tension
influences the final seam pattern.
The needle thread tension is defined by the pre-tensioner, the
main tensioner and the additional tensioner.
Proper setting
If the tension of needle thread and hook thread is identical, the
thread interlacing lies in the middle of the sewing material.
Set the needle thread tension so that the desired seam pattern is
achieved with the lowest possible te nsi o n.

4.7.1 Setting the needle thread tension
Fig. 13: Setting the needle thread tension
(4) - Main tensioner
(5) - Addi tional tensioner
Setting the pre-tensioner
When main tensioner and additional tensioner are open, a small
amount of residual tension of the needle thread is required.
This residual tension is generated by the pre-tensioner.
The pre-tensioner influences the length of the cut needle thread
end. The cut needle thread end is the initial thread for the next
seam. Reliable operation of the thread cutter can only be achieved
with a properly set pre-tensioner.
To set the pre-tensioner:
1. Turn the pre- tensioner (6) until the front side is flush with the
bolt.
• Set a shorter initial thread: turn counterclockwise
• Set a longer initial thread: turn clockwise
Setting the main tensioner
The main tensioner determines the normal tension during sewing.
Set the main tensioner as low as possible.
(6) - Pre-tensioner
Operating Instructions 670/680 - 00.0 - 01/2017 27
Page 30
Operation
Important
The thread interlacing must be exactly in the middle of the sewing
material. With thin sewing material, excessive thread tension can
lead to undesired gathering and thread breaking.
To set the main tensioner:
1. Set the main tensioner (4) so that an even stitch pattern is
achieved.
• Increase the tension: turn clockwise
• Reduce the tension: turn counterclockwise
Setting the additional tensioner
The additional tensioner (5) is used to quickly adjust the needle
thread tension, e.g. for thickened seams.
The additional tensioner (5) can be switched off at the thickened
seam to loosen the seam. To tighten the seam, the additional
tensioner (5) is switched back on after the thickened seam.
To set the additional tensioner:
1. Set the additional tensioner (5) so that an even stitch pattern
is achieved.
• To increase the tension:
Turn adjusting wheel clockwise
• To reduce the tension:
Turn adjusting wheel counterclockwise

Only set the hook thread tension with the machine
switched off.
Fig. 14: Setting the hook thread tension
(1) - Adjusting screw
To set the hook thread tension:
1. Use the adjusting screw (1) to set the tension spring.
• Increase the hook thread tension:
Turn the adjusting screw(1) clockwise
• Reduce the hook thread tension:
Turn the adjusting screw (1) counterclockwise
2. Perform a sewing test and check the stitch pattern.
3. Readjust the hook thread tension if necessary.

4.8 Setting the needle thread regulator
The needle thread regulator regulates the amount of needle thread
required for forming the stitch.
Important
An optimum sewing result is possible only when the needle thread
regulator is exactly adjusted!
Fig. 15: Setting the needle thread regulator
(1) - Scre w (2) - Needl e thread regulator
Proper setting
The needle thread loop slides at low tension over the thickest point
of the hook.
To check the setting of the needle thread regulator:
1. Fold open the sewing table.
The hook and the needle thread loop are visible.
2. Turn the handwheel and perform a visual inspection of the
needle thread tension.
To set the needle thread regulator:
1. Loosen the screw (1).
2. Set the position of the needle thread regulator (2).
• To set a larger amount of needle thread:

Lint and thread remnants should be removed after every 8 op erating hours using a compressed air gun or a brush. If very fluffy
material is being sewn the machine must be cleaned more
frequently.
A clean machine provides protection from faults during the sewing
process.

6.2 Lubricating
WARNING
Risk of injury from contact with oil!
Contact with oil can cause irritation, rashes,
allergies or skin injuries.
ALWAYS avoid long-term contact with oil.
ALWAYS thoroughly wash the affected areas if
contact with oil occurs.
CAUTION
Risk of environmental damage from old oil!
Incorrect handling of old oil can result in severe
environmental damage.
ALWAYS observe the legally prescribed
regulations for handling and disposal of mineral oil.
Take care to ensure that oil is NEVER spilled.
For lubricating the machine, use only lubricating oil DA 10 or oil
of equivalent quality with the following specifications:
• Viscosity at 40° C: 10 mm
• Flash point: 150° C

7.5 Setting the working height
CAUTION
Risk of musculoskeletal damage!
The operator can sustain musculoskeletal
damage if failing to comply with the ergonomic
requirements.
Adjust the working height to the height of the
person who will operate the machine.
CAUTION
Risk of injury if tabletop drops rapidly!
The person loosening the screws on the bars of
the stand can sustain crushing injuries if the
tabletop drops rapidly. The tabletop is more likely
to drop rapidly when the machine head has
already been inserted.
Make sure not to allow the tabletop to drop when
loosening the screws.
Always have the working height adjusted by
2 people.
Setup
The working height can be adjusted continuously to any height
between 750 and 900 mm.

7.7 Electrical connection
DANGER
Risk of death from electric shock!
Work on the electrical system involves the risk of
sustaining serious, including fatal, injuries.
The machine should only be connected to power
by qualified electricians.
Disconnect the power plug before carrying out
work on the electrical equipment.
Make sure the power plug is not accidentally
plugged back in.
Important
The voltage on the type plate of the sewing motor must correspond
to the mains voltage.
Connecting the control
To connect the control:
1. Tighten the control on the tabletop.
2. Guide the cable from the machine head through the tabletop
cutout.
3. Connect the cable with the control.
Both the cable and the appropriate plug are color-coded and
marked with a symbol.

7.8 Pneumatic connection
The pneumatic system of the machine and of the additional equipment must be supplied with dry and oil-free compressed air.
The supply pressure must lie between 8 and 10 bar.
NOTICE
Property damage from oily compressed air!
Oil particles in the compressed air can cause malfunctions of
the machine and soil the sewing material.
Ensure that no oil particles enter the compressed air supply.
NOTICE
Property damage from incorrect setting!
Incorrect system pressure can result in damage to the
machine.
Ensure that the machine is only used when the system
pressure is set correctly.

7.8.2 Setting the operating pressure
Proper setting
NOTICE
Machine damage possible from incorrect pressure!
Incorrect system pressure can result in damage to the
machine.
Make sure the operating pressure is set correctly to 6 bar.
Proper setting
Refer to the Technical data ( p. 95) chapter for the permissible
operating pressure. The operating pressure cannot deviate by
more than ± 0.5 bar.
Fig. 42: Setting the operating pressure
(1) - Pres sure controller (2) - Pressure gage
To set the operating pressure:
1. Pull the pressure controller (1) up.
