Mounting and setting of the plunger drive
(Fig. 12, Fig. 16, Fig. 17 and Fig. 18)
ATTENTION!
Switch the machine's electric power off and pull the power
plug.
After e.g. changing the pivot drive, the plunger drive must be remounted and
reset. Please observe the following instructions:
1. Swivel drive (1) must be aligned in its secured state so that the shaft of
the swivel drive, looking from the back, is turned to the limit in the
clockwise direction. (Fig. 16)
2. Insert and screw in the connection flange (2) to the limit so that the first
threaded hole is over the groove and fix with the threaded pin with journal
(3) and secure with nut (4). (Fig. 16)
3. Mount shaft (5) and secure to the surface with the 2 threaded pins (6).
Then tighten the last threaded pin (7) and secure the rest of the nuts (4).
(Fig. 16)
4. Setting of the lever (8) on shaft (5) (Fig. 16):
a. Turn the swivel drive in the clockwise direction, as seen from behind,
to the limit
b. Set lever (1) so that between setting ring (2) and bearing bushing (3)
there is a distance in the lower arm of approximately 2.5 – 3.0 mm.
Tighten lever (1) with cylinder head screw (4). (Fig. 17)
c. Turn the swivel drive in the anti-clockwise direction, as seen from
behind, until the plunger lifts the needle 0.1 – 0.2 mm.
d. Turn cam (5) and lever (3) to one another until the nose rests against
the lever. (Fig. 12)
e. Turn cam (5) approx. 2 mm back and tighten lever (3) with cylinder
head screw (4). (Fig. 12)
f. Bore lever (3) with shaft (7), screw in threaded pin (6) and tighten.
(Fig. 12)
4. Screw machine upper part to the tabletop.
5. Plug in power plug and switch machine on by the main switch.
6. Set the plunger value “0” in the first backtack of the stitch program. (Refer
for this to the operating instructions of the respective sewing drive.)
7. Switch the machine off by the main switch and switch it on again. (A
reference run is made and the first backtack is approached with the
plunger value “0”.)
