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

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.
