oil it, see also Chapter 10 Maintenance and Care.
● Have technical staff check whether the
machine’s motor may be operated at the
existing mains voltage and whether it is
connected properly.
The machine must only be connected to a grounded socket!
Have the home position of the machine drive verified by certified technicians
before the initial commissioning! Have these settings carried out where required (see the drive service manual in Chapter 4.4.
8.05 Switching the machine on / off
● Switch the machine on (see Chapter 7.01 Main switch).
8.06 Machine drive home position
● See the drive service manual in Chapter 4.4
8.07 Checking the start inhibitor function

The bobbin fills up during sewing.
If the machine is only run for bobbin winding (without sewing), a bobbin case
must be fitted in the hook.
Otherwise a jammed thread may damage the hook!
● The tension of the thread on the bobbin 1 can be adjusted with the knurled screw 4.
● The bobbin winder stops automatically when the bobbin 1 is sufficiently full.
● Remove the filled bobbin 1 and cut the thread with the blade 5.
● The fill amount of the bobbin 1 can be adjusted with the pin 8 (loosen the screw 9 and
tighten it again)
If the thread is wound unevenly:

.01 Maintenance intervals
Cleaning ........................................................ daily, several times if in continuous operation
Clean the hook area ...................................... daily, several times if in continuous operation
Check oil level ...................................................................................... daily, before start-up
Lubricate the bevel gears ..................................................................................once as year
Oil the edge trimmer -731/01 ................... weekly, several times if in continuous operation
10.02 Cleaning the machine
The required cleaning cycle for the machine depends on the following factors:
● Single or multi-shift operation
● Dust formation caused by the workpieces
These maintenance intervals are based on an average running time of a single
shift production shop. Shorter maintenance intervals are recommended for
increased running times.
Optimal cleaning instructions can therefore only be determined on a case-by-case basis.
Disconnect the machine from the electricity mains for all cleaning work by
shutting off the main switch or removing the mains plug! Risk of injury due
to accidental machine start-up!
The following tasks are recommended
during single shift operation to avoid
operational errors:
● Tilt machine backwards.
● Clean the hooks and hook area daily or
more often during continuous operation.
Return the machine to its
upright position using both
hands!
Danger of injury by crushing
between the edge of the
machine and the table top.

● Whenever it is necessary to refill the
reservoir, tilt back the machine and let
it rest on the sewing head support.
● Fill oil through the hole 1 into the
reservoir 2 up to the level of the front
edge (see arrow).
2
Only use oil with a centre viscosity of 22.0 mm
of 0.865 g/cm3 at 15 °C.
The oil reservoir must always
have oil in it.
Return the machine to its
upright position using both
hands!
