Motor drive via V-belts
Tensioning the V-belt
C a u t i o n ! Danger of injury!
When checking the belt tension, switch off the machine at
the mains. Do not operate the machine without the belt
guard. Otherwise there is a
D A N G E R
of crushing
fingers, of injuries to the body and of pulling in parts of
clothing.
The tensioning of the V-belt is carried out by swivelling the motor underneath
the table plate after releasing the retaining nut with SW 24, (3) in Fig. 2.
The V-belt must not be tensioned too much, especially with the stop motor. You
should be able to compress it with light thumb pressure by about 2 cm.
Too little V-belt tensioning can impair the positioning of the machine and
therefore impair the function sequence.
3.4.2
Positions of the machine
C A U T I O N ! Danger of injury!
Danger of crushing fingers and needle through stitching as
well as pulling in of parts of clothing.
Keep fingers and hands away from moving parts when
setting the position generator and checking the positions
with switched-on machine.
General:
Stop motors require a position generator, which takes the mechanical setting of
the machine from the main screw and transmits this to the control of the motor.
With this, for instance, the thread cutter can always be electrically approached
in exactly the same needle looper position.
(Fig. 2)
The correct position of the position generator to the flange is marked with a
spot of paint.
To adjust or to remove, release the two clamping screws (2), Fig. 2. tighten
these firmly prior to commissioning.
