In the three-phase sewing drives used it is the rotating field of the supply voltage which
determines the direction of rotation.
– Insert the mains plug.
– Check the direction of rotation of the motor fan (behind the fan grille 1) by briefly
turning on the main switch. The arrows in the above illustration show the correct
direction of rotation for the two frame types.
– If the direction of rotation is wrong, two phases in the mains plug must be swapped
over.
CAUTION:
Before the special sewing machine is started it is essential
to check the direction of rotation of the motor.
Switching it on can cause damage if the direction of
rotation is incorrect.
The sewing drives are fitted to the frames in two different
positions.
The direction of rotation of the sewing drive depends
on which frame is used.
