12) Adjusting position of the belt puller
The belt puller is adjustable in four directions including
up, down, left, and right.
When the needle is located below, the belt should
closely contact the needle plate. Otherwise, smooth
seaming is difficult to get.
11) Lapper Installation
Insert the lapper guide pin into the overall hole on the
upper bed cap. Check if the end of the lapper is not too
close to the presser foot.
