Correcting the Garnet flow amount

1. If you don’t have the correct flow, either turn the round dial up if you need more garnet or down if you have too much. If you are unable to achieve the correct flow, do the mini-hopper maintenance found in the maintenance section of the operator manual or in the “Maintenance Help Screens”

Disable Garnet

Locate the Garnet Control Board

Enable the WaterJet

Making adjustments

Monitor the Control Board

Monitor the lights on the board while the machine runs a program. When the waterjet begins a cut,
the lights should turn on, when it finishes, they should shut off. (They should shut off between the cuts while the machine moves.) Run a complete job and monitor this, when finished, turn the garnet flow sensor back on by going into the advanced setup screen and pressing on the garnet flow button. When the button turns gray, the garnet flow sensor is active again.
