Precautions for Installing Air Springs

1. Air springs must not be pressurised unless they are restricted by an outside frame or by a suitable load.
2. Strokes must be limited by the direct use of bump stops or external stops. When stacking air suspensions, special cares must be taken to ensure the air springs are guided and fixed.
3. An Air bag is a single acting air actuator and must not be used below atmospheric pressure.
4. Please check the overpressure in case of quick compression.
