HP coil on a robot axis leaks or breaks

Robot coils flex with every move and fatigue in time.

Safety first: Switch off the pump, release all pressure (open the on/off valve or bleed-down valve) and lock out before you open any high-pressure part. Never put a hand or tool near a running jet.

Coils used at the edge of their range break first.

How to check: Check the robot path for extreme axis angles.
