Pfaff 3334 User Manual

d. Adjusting the Work Clomp
Adjust the work clamp frame on the feed plate carrier bar so that the
needle will neither be deflected by, nor strike against, the work clamp
feet, regardless how large the tack may be. The work clomp spring pres
sure can be regulated by nut h (Fig. 30).
The clamp foot lifting lever (Fig. 2) must not contact the lifting studs pro
truding from the work clamp face plate as, otherwise, the work clamp feet
will not press the material against the feed plate firmly. After the machine
has completed the last stitch and stopped, adjust the presser
bar and the
clomp foot lifting lever so that the top edge of the latter is positioned
just below the work clomp foot lifting studs.
e. Timing the Stop Motion
