Caution: Danger of injury !
Switch off the main switch.
Adjust the lifting motion of the folder only with the sewing unit
switched off.
Standard checking
When the folder is lowered
–
Lower the folder on the fabric sliding sheet. In this position there
must be a clearance of 0.3 - 0.5 mm between the guide roller 7 and
the lowest point of the guide groove 6.
When the folder is raised
When the folder is raised, there must still be some clearance between
the guide roller 7 and the highest point of the guide groove 6.
–
Press the folder down to the fabric sliding sheet by hand.
–
For this purpose turn the stop 8 back, if required.
–
Check the air gap between guide groove 6 and guide roller 7.
–
Lift the folder up to the upper stop 3.
–
Check the air gap between guide groove 6 and guide roller 7.
Correction
–
Swing the folding station out.
–
Adjust the stop 3 at the pivoting cylinder 4.
If - with the folder lowered - the guide roller 7 hits the guide groove and
the folder is not lowered as far as required, the guide groove has to be
readjusted (see next page).
