Assemble the Machine
4.1
Mount the shaft (Fig. 1)
First, remove any grease from the shaft. Mount the parts in correct order onto
the shaft and put it into the machine column so that it sticks out about 30 mm
on the left. Then put a drop of “Loctite” on either end of the shaft, that is, on the
left end sticking out from the column, and on the ball bearing on the right.
(Loctite, Kapillar 290)
NOTE! The surfaces to be joined must be absolutely clean. Only then
you may fit the shaft completely into the machine column. Turn
it slightly, so that the glue on the ball bearing is evenly
absorbed. Fix stitch regulating eccentric (A) (fig.1).
See chapter “4.2 Mount stitch regulating eccentric 353.0031”.
Push the shaft to the left up to the stop, and fasten setting ring
246.0103 on the right of the shaft in order to eliminate any axial
play.
About an hour later when the glue (Loctite, Kapillar 260) is hard, you may
continue to assemble and adjust the machine. When assembling after a repair,
it is not necessary to take off the left hand wheel.
4.2
Mount stitch regulating eccentric 353.0031
Fit the left handwheel onto the shaft so that the first screw in direction of sewing
fits into the drill hole on the left of the shaft and point upwards.
Turn guide disc 153.0031 so that you can easily slide down set eccentric
132.0074. Then screw the first screw 176.0632 into the regulating eccentric, but
ensure that regulating bolt 137.0026 can still freely be turned in the shaft. Then
turn hand wheel with shaft by 180 degrees. Screw second screw 176.0532 into
the regulating eccentric right to the stop. Fasten guide disc 153.0031.
Push the shaft to the left up to the ball bearing, slide set collar 246.0103 on the
right shaft side all the way to the ball bearings, and tighten. The shaft is now
fastened.
Let stitch-regulating eccentric 137.0014 level out and tighten.
Fix two lubricated springs 161.0063 and bolts 135.0062 into the drill hole of the
hand wheel (Fig. 2, Fig. 3 und Fig. 4).
