The zero position ofthe step m otors is determ ined by the reference

S etthe value 50 forthe basic position ofthe differentialfeed in the

M ove the bottom feed to the frontreversalpointby turning the
handw heel.

–

M easure the distance from the frontedge ofthe frontfeed-dog to
the hind edge ofthe hind feed-dog.

–

M ove the bottom feed to the rearreversalpointby turning the
handw heel.

–

M easure the distance again.

The difference betw een the frontand hind distance m ustnot
exceed 0 m m to + 0.02 m m atthe rearreversalpoint.

S hould the difference exceed + 0.02 m m ,this m eans thatthe feed
stretches the m aterial.
The adjustm entofthe differentialfeed has to be changed to “plus”.

A fteropening the clam ping screw 1 the reference disk 3 has to be
turned dow nw ards (tow ards the proxim ity sw itch)and fixed again
by the clam ping screw 1.

S hould the difference be below 0 m m ,this m eans thatthe feed
distributes fullness.Thus the adjustm entofthe differentialfeed has
to be changed to “m inus”.

A fteropening the clam ping screw 1 the reference disk 3 has to be
turned upw ards (aw ay from the proxim ity sw itch)and fixed again by
the clam ping screw 1.
