Open the cover to allow the WaterJet interior to dry and to prevent corrosion of the wiper motor. Removing Support Material with Sodium Hydroxide To remove thin layers of Support material or from hard-to-reach areas, and to give the model a smooth, clean finish, soak the model in a 1-percent solution of sodium hydroxide (NaOH, known as caustic soda). The amount of time required to soak the model in the solution depends on how delicate it is and how much Support material needs to be removed, but it is typically between half-an-hour and several hours. In any case, you should remove as much Support material as possible before the treatment, and rinse the model thoroughly with the WaterJet afterwards. Warning: Toxic Hazard Caustic soda might cause chemical burns, scarring and blindness. Take adequate safety precautions; always use nitrile gloves when handling caustic soda and models soaked in it. Warning: Fire Hazard Mixing caustic soda with water creates heat that could ignite other materials. Never pour water onto caustic soda. Always add caustic soda to water.

Open the connector and remove the old thread-seal tape. ® b. Wrap fresh thread-seal tape (for example, PTFE or Teflon tape) on the thread of the connector. Wrap thread-seal tape clockwise, in the direction of the thread, so that it doesn’t unwrap when tightening the connection. c. Close and tighten the connector. DOC-01201 Rev. C © C opyright 2012-2019 Stratasys. All rights reserved.
Page 38: Troubleshooting
Troubleshooting The following are typical issues and suggested solutions. The pump turns off every 10 to 15 seconds. 1. Detach the spray nozzle tip from the nozzle selector valve in the WaterJet and let the water run for about five minutes with the pump on. This action removes air and dirt trapped in the water pressure pump and in the water supply hose. 2. Check that the nozzle tip is not blocked or damaged. 3. Re-attach the spray nozzle tip. The pump stops working. • Reduced water flow might cause the pump to overheat and stop. Check that the tap is open fully and that the water supply and pump filters are not clogged. • Check the main fuse and replace, if necessary. DOC-01201 Rev. C © C opyright 2012-2019 Stratasys.
