Recalibrating the LUCCA E61 Flow Control
If your flow control does not produce minimum flow or if your flow feels restricted, you can try recalibrating your flow control device.
Tools Needed:
Flat head screw driver (If needed)
Make sure that your machine is off and cool before beginning.
1.Turn your flow control paddle clockwise all the way to the minimum position.
2. Using a 2mm Allen key, unscrew the small screw but leave it inside of the paddle for safekeeping.

3. Lift the paddle straight up off of the spindle (You may need to use a flathead screwdriver to help lift it off if it is particularly tight).
4. By hand or using the included spindle tool, turn the spindle clockwise until it stops. This is the fully closed position. Then back the spindle up ever so slightly—a hair's width—we want to avoid constant metal-on-metal contact during normal operation.
5. Replace the paddle in the fully closed position and use the Allen key to screw the set screw back into place. 
Turn your machine on and test.
