The Zigzag Regulator Mechanism
The zigzag regulator mechanism (Fig. 101) embraces the stitch width regulating
mechanism in the machine arm and the stitch width control on the outside of
the machine arm.
The stitch width control comprises
stitch width dial A,
zigzag finger-tip control F, and
needle position lever B.
Before you strip the stitch width control, it is advisable to make on inconspi-
cuous mark on the machine arm opposite the red mark on the zigzag regulator
barreL
Stripping the Automatic Mechanism
If the machine is equipped with on automatic embroidery mechanism, this must
be stripped before the zigzag regulator mechanism can be removed from the
machine. To do this, proceed as follows:
Disconnect tension spring m (Fig. 51) from the zigzag regulator arm (1 06178),
and unscrew pressure spring assembly o. Toke out the screws in the bose, and
lift the automatic embroidery mechanism out, without applying force. Turn
stitch width dial A to "4", and
loosen the set screws on the three engaging
lever eccentric studs. Pull out the eccentric stud of rear engaging lever d l. Set
stitch width dial A on "0", and strip engaging levers d 2 and d 3. To replace the
automatic embroidery mechanism, simply proceed in reversed sequence (see
also page 71 ).
Dismantling the Stitch Width Control
Turn stitch width dial A to "0";
set needle position lever Bat its central position;
turn out the set screw (b in Fig. 102) on the zigzag regulator barrel which con
be reached from above;
push up finger-tip control F;
shove the stitch width regulating mechanism in the arm to the left;
turn the barrel slightly to the right, and pull it out cautiously, without applying
force. If desired, tool No. 106300-303 con be supplied by Pfaff at extra cost.
This tool serves to facilitate the turning and removing of the barreL
