3.3 Sense of rotation
The correct sense of rotation of the hand wheel is clockwise in line of vision on
the hand wheel.
3.4 Motor drive via V-belts
3.4.1 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.
The V-belt must not be tensioned too much, especially with the stop motor. You
should be able to depress 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.
3.5 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:
The machine requires a pulse generator that is mounted on the main shaft
(handwheel) of the machine and that detects the mechanical position of the
machine and sends it to the control.
The pulse generator has to be mounted on the machine as follows:
The pulse wheel (1) from the encoder must be positioned so that the
outgoing edge (disc transition from "light" to "dark" in the machine direction)
in the sensor (2) when the machine with the needle reaches the front
position (Fig. 2).
