Clearing the Dry Abrasive Hopper

In addition to the Dry Abrasive Hose, another area that an abrasive hose blockage can occur is in the abrasive hopper and/or mechanism at the bottom.

1. Remove the Abrasive Slip Cover at the bottom of the hopper. Check if the cover is damp or wet.
[NOTICE] If your abrasive valve does not look like the one pictured, please contact customer support through our ticketing system in order to have the upgrade sent to you. If you still have the older plug style and try to remove the head in this fashion, it will cause damage to your valve.
2. Disconnect vibration motor leads, untie cable ties as needed.
3. Pull out the dry abrasive hopper from WAZER unit.
4. Dump all abrasive from hopper into a clean dry bucket. Observe carefully if any congregated sand falls off. Vacuum the hopper if needed.

5. Shine a flashlight from the plug hole, depress the pinch valve button and observe from the abrasive hopper outlet
a) If light from the flashlight is seen, pinch valve passage is clear and the abrasive clog/obstruction has been cleared
b) If no light is seen, pinch valve passage is blocked and you must continue with the rest of the procedure.

6. [CAUTION] Safety glasses and dust mask required While keeping the button on the abrasive valve depressed, use a compressed air source (set to no more than 10 psi) to blow clear the passageway from hopper outlet. NEVER use a higher pressure or perform this step without the abrasive valve button depressed. 
7. Repeat steps 5 and 6 until the passage is clear.
8. Slide dry abrasive hopper into WAZER, reconnect vibration motor leads, abrasive valve cover and line, and abrasive line end. Refill hopper with dry abrasive.
