Fig.322: Tubing of the nozzle station air supply
► Check the tubing of the nozzle station air supply:
1. Tubing 1 is recommended. The tube is running
behind the screw head, so the lining of the tube
will not touch the conveyor belt.
2. Tubing 2 is not recommended, as it may touch
the conveyor belt and will be cut over time.
3. Use the hose clamp.
Fig.323: Fixing the central unit (shown from above)
► Put in the four screws(1) in position and loosely
tighten them.
► Move the central unit to the outer side of the
machine(2) to ensure a maximum distance(4) to
the conveyor side(3).
