their spread positions during the cutting and sewing procedures.

Pull the mains plug before setting.

With closed and spread clamping plates loosen screws 1.

Bring the securing blocks 2 into contact with bracket 4 and the
spring-mounted catch bolt 3. The securing blocks should, however,
exert no pressure on the bracket thereby.

Screws 1 again.

Repeat the spreading procedure with closed clamps.
The spring-mounted catch bolt 3 must thereby jump in front of the
securing blocks 2.

Check if the securing blocks 2 can move unhindered over catch
bolt 3 with open clamping plates.
