4.4 Checking the Direction of Rotation of the Motor

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.

5. Pneumatic Connection

ATTENTION !

For a fault-free functioning of the pneumatic control sequences, the

following notes are to be observed.

The compressed air supply must be so conceived that even at the

moment of the greatest air consumption a minimum operating pressure

of 5 bar is not fallen short of.

The connection to the compressed air supply is made with the

accessories available as optional equipment ( 0797 003031 ) or with

in-house connection material.

Operating pressure 2 = 6 bar
