Unless shipped directly, every sewing machine, when received at our
dealers, is unpacked, carefully checked for possible damage inflicted in
transit, cleaned, and tested for perfect sewing before being released For
delivery to the customer.
2. Engaging and Disengaging the Sewing Mechanism
Two varieties of the PFAFF 28 are available:
1. with standard-size beak shuttle;
2. with extra large beak shuttle.
Machines equipped with standard-size beak shuttles have a balance
wheel with exchangeable pulley so as to permit easy conversion of the
machine far foot or power drive respectively.
The machines are shipped with the sewing mechanism disengaged so
that only the pulley will rotate when treadling or starting the motor. To
engage the sewing mechanism, hold the balance wheel with your left hand
and turn the large knurled lock nut R wth your right hand clockwise
in the direction of the arrow (see photo il.
When lock nut R is turned counter-clockwise, the sewing mechanism is
disengaged for winding the bobbin.
Ta increase the piercing power of the needle, the machines with extra
large beak shuttles are fitted with a larger and heavier balance wheel
with fixed pulley so that it is nat possible to disengage the sewing
mechanism of these machines.
