ATTENTION !
Before commissioning the sewing unit it is essential that the direction
of rotation of the motor be checked.
Turning on the sewing unit with an incorrect direction of rotation can
lead to damage to the unit.
–
The correct direction of rotation of the handwheel is shown by the
arrow on the handwheel belt guard 1.
–
If the direction of rotation is not correct, then it must be checked if
the power supply generates a clockwise rotary field.
If this is the case, then 2 phases in the connection plug must be
interchanged.
