SINGER W102 - Manual (Page 11)

IMPORTANT NOTES
Fig- 1
The rotation of the machine must always
be in the direction shown by the arrowy
(See illustration with the arrow curving
and pointing over the hand wheel towards
the user) and never in the opposite
direction.
The machine should never be run except
when there is material under the presser foot and when the presser
foot is dowm to avoid thread tangling and breaking.
At the end of the seam, to remove the work from machine, bring
the needle to the highest position by turning the wheel in the direc­
tion of the user (never in the other direction).
Raise the presser foot (this, also releases the upper tension discs,
allowing the thread to pull out freely).
Remove the work by pulling it gently in the direction of sewing, in­
sert the threads and cut them on the blade of the thread cutter.
NOTE: Raise the presser foot only when the needle is at the top
position except when you have to continue sewing in a different
direction to that of the preceding seam; in this case, take care not
to pull or bend the needle, and raise the foot a little with the
needle still piercing the material. The work can be turned around the
needle, lowering the presser foot afterwards.
