How to troubleshoot TKR Group VAS 6790/2 Rivet Tools if it's not working?
- LLuis WellsAug 7, 2025
If your TKR Group Rivet Tools are not working, there are several potential causes. First, ensure the compressed air supply is connected. Next, check that the black and blue control lines are correctly connected and properly seated. Also, verify sufficient air pressure at the pressure intensifier. Ensure the hydraulic hose assembly is correctly coupled. If these steps don't resolve the issue, the Compact Booster or the control valve (operating unit) may be defective, requiring repair by the manufacturer or a service partner.
