20026
048080GEB
The timing of the feed dog and needle bar can be made with
the help of the gauge 10-3 (Fig. 34).
Insert the pin " B " of the gauge into the timing hole of the feed
dog eccentric A 20026.
Turn the flywheel slowly toward you until the gauge rests on the
two side rims of the machine as shown in Fig. 34.
If the timing is correct, the needle bar " E " should now be at its
lowest position and the connecting link " H " (Fig. 34) should be
in a straight vertical position.
If the position is not correct rectify it in the following way: loo
sen the two screws 048080 GEB of the eccentric 20026 (Fig. 33)
and place the gauge 10-3 over the two side rims of the machine
then insert the pin " B " in the corresponding hole of the eccentric
20026 and turn the flywheel until the needle bar is in the lowest
position.
Tighten the two screws securely 048080 GEB after the adjust-
ment.
The above mentioned procedure is only made if the feed dog
does not move correctly in relation to the needle bar.
