How to Clean out the water jet abrasive tube. 

From time to time when using the water jet at Pier 9, the clear tube that feeds abrasive to the head clogs up and stops the water jet from cutting your material.

This is usually due to water leaking into the tube which must remain dry for Garnet to flow correctly. 

Users are allowed to clean the tube themselves to keep their project flowing. Follow the steps below to clean the abrasive tube and please remember to wear the appropriate safety gear (goggles, gloves).  Never put yourself in an unsafe position to perform this fix. 


Noticing a clog.

It is very important to always be at the machine, be attentive to the cut, and keep your hand close to the stop/pause button when using the water jet. When a clog appears in the Abrasive tube, Garnet will stop flowing into the head and only water will shoot out. Traditionally this will stop cutting your material and spray water 360 degrees around the head. When this happens Stop the cut immediately.

Step 1: Inspect the line and disconnect the Abrasive hoses.

The Abrasive tube is the clear tube that connects to the side of the water jet nozzle head. There is also a smaller 2-3 inch clear tube that connects the big tube to the print head. Pull those free carefully so you do not loose the small tube into the water jet pool. If any of the tubes are damaged please stop and let Shop Staff know.

Next, inspect the Hopper attached to the Waterjet head. On the bottom of the hopper, there is a small Garnet feeder that is connected to the other end of the Abrasive tube. Disconnect the Abrasive tube by pulling free the clear tube from the bottom of the Garnet feeder.
