Clamp rail clamping pressure adjustment:
After any works to the main clamp, the clamping pressure
and the alignment of the clamp rail to the needle must be
checked.
1. Check to see if the main clamp exerts pressure onto
the sewing piece evenly along the entire length of the
rail by lining up a piece of fabric to the insertion posi-
tion and lowering the main clamp.
2. Check clamping pressure by trying to pull the sewing
piece out of the clamp at several locations along the
clamp rail.
3. Fig. 15: If the pressure force is uneven or insufficient,
remove clamp rail and change the position of the two
adjusting screws 1 at the inner side of the clamp rail.
If the adjusting screws are screwed in, the pressure of
the clamp rail onto the working plate increases as the
height H of the main clamp in the downward direction
changes.
4. Repeat adjustment and recheck with lowered main
clamp until clamping pressure is distributed evenly alo-
ng the entire length of the clamp rail.
