• The grooves of the adjusting screws indicate the position.
• When the screw is open, the groove sits above the stud.
• When the screw is closed, the groove sits below the stud.
13. Multi-functional application
Conventional 310 ml cartridges can be tensioned using
the black DK union nut.
The blue adjusting screw remains closed when processing.
