Pfaff 360 User Manual

turn the sewing hook on its shaft until its point is opposite the center line of the
needle. At the same time, set the hook as close to the needle as p·ossible, the
proper clearance between both parts being .oo-4•, or 0.1 mm . lightly tighten
whichever hook set screw can be reached most easily, and double-check to
ascertain that the setting is correct. Then remove the clamp and tighten both
hook
set screws securely.
The Upper Driving Belt Sprocket
Retiming the sewing hook normally will not alter the position of the lower
driving
belt sprocket on its shaft . Both helical gears on the hook and hook
drive shafts are secured in position by a flat spot or a pin.
For
this reason, if the sewing hook should be out of time, check the position of
the upper driving belt sprocket (and of the feed eccentri c) in relation to the
arm shaft. The timing marks on both the sprocket and the arm shaft must be in
alignment.
