3Set-up and commissioning
C A U T I O N ! Danger of injury!
Due to pulling in of parts of clothing or hair as well as danger of
crushing of fingers!
3.1 Unpacking of the machine
The machine is only delivered completely with stand.
The thread stand and other machine accessories are included in the packaging.
Before disposing of the packaging material, carefully check whether all accessory
components have been unpacked.
3.2 Setting up the machine (Fig. 1)
A T T E N T I O N !
If you release or even loosen positions that are marked in yellow,
important factory settings can get lost!!
These screws do not have to be released for maintenance work.
If, however, you do release these screws, please contact the
manufacturer.
A T T E N T I O N !
Lubricate the hook every day with a drop of oil.

10 BA_710_A1_221010_en.doc
A T T E N T I O N !
Before starting the machine, check that the electrical
specifications given on the type plate of the motor, in particular
the network voltage and frequency, are appropriate for your
electric system and that all other connection values, e.g. for air,
comply with the values specified on the machine and in the
operating instructions.
Carry out the electrical connection according to the cable identification or the
supplied connection diagram.
Check that all screws on the stand are firmly installed and retighten if necessary.
After the machine lifting and several other activities happen pneumatically, a
compressed air connection of 6 bar is required (see point "2.4 Technical data"). The
air pressure can be regulated with the service unit.
After assembling the individual parts, mount the thread stand on the back right of the
table top. (Fig. 1).

3.3 Sense of rotation (Fig. 2)
The sense of rotation of the handwheel is counter-clockwise.
Fig. 2
3.4 Motor drive via toothed belt
3.4.1 Tension of the toothed belt (Fig. 3 and Fig. 4)
C A U T I O N ! Danger of injury!
To check the tension of the toothed belt, switch off the machine
electrically, pull the power plug, and depress the motor switch
pedal to make sure that the machine is truly switched off.
The tension of the toothed belt should not be too great. Slight thumb pressure should
be able to push the belt through by approx. 5 mm. (Fig. 3)
A too little or too great toothed belt tension can deteriorate the positioning of the
machine and therefore impair the function sequence.
Tensioning the toothed belt (Fig. 4):
-Loosen the 4 screws (1) from the cover (2).
-Loosen the 4 screws (3) from the motor flange (4) and tighten the belt (5) by
pushing down the motor flange (4).
-Retighten the 4 screws (3).
-Refit the cover (2) with the 4 screws (1).

3.5 Intermediate lifting (Fig. 5)
If it is necessary to use the knee lever for intermediate lift when pneumatic lifting is
fitted, this can be done with the knee lever already fitted as standard.

4Notes on usage
4.1 Needle
Only use the approved GROZ-BECKERT needle system 1828 E with thickness 80/12.
NOTE: An intact needle is very important for ensuring good quality stitching.
Bent needle points, that may only be visible under a magnifying glass,
will lead to poorer sewing results. Replace your needles in time!
G u a r a n t e e n o t e !
This machine has been set and sewn off with genuine GROZ-
BECKERT needles.
No guarantees can be given when the machine is readjusted for
the use of different needles.
4.1.1 Thread
The following sewing threads have been approved by STROBEL Spezialmaschinen
GmbH in consultation with the automotive industry for use with the 710 machine:
Thread manufacturer / description
AMANN / Serafil
GÜTERMANN / Tera
Polyester threads endless twisted of thickness 120 or 180.

16 BA_710_A1_221010_en.doc
4.2 Inserting the needle (Fig. 6)
C A U T I O N ! Danger of injury!
Switch off machine electrically and confirm that the machine is
really in standstill position by operating the treadle for the motor
control before changing the needle.
Otherwise there is a danger of injury from crushing and needle
punctures.
The curved needle shape determines its position in the needle lever. Attention should
be paid only to ensure that the needle piston is pushed to the stop in the channel of
the needle lever and that the screw (2) of the needle clamping plate (1) is tightened
well.
