  1. A Gas Spring is filled with oil and highly pressurized gas. Therefore, do not try to open or drill into a Gas spring.
  2. JUNIOR Gas Springs should be installed with the rod end downward.
  3. First, check and compare design, length and mountings before installing the new gas spring.
  4. Remember that it is the gas springs that holds the bonnet and rear hatch.
  5. To avoid injuries of any kind, ensure a secure fastening of the bonnet or rear hatch when replacing springs.
  6. Check mounting points in the body. If they are damaged they should be changed or repaired.
  7. We recommend that the springs on the vehicle should be replaced in pairs.
  8. On a car that has been extra equipped with blinds or spoilers for example. There is a risk that the rear hatch may be too heavy for gas spring designed with the original elevating power.
  9. Gas Springs are design to bear axial loads only. Consequently any side load forces should be avoided. Specifically when Gas Springs are equipped with eyelet end fittings, special attention should be paid to design of connecting shafts in order to provide appropriated clearance (according to each application). As an indication only, we would advise: 0.3 to 0.5 mm clearance on shafts diameter and 0.5 to 1.0 mm clearance on each side of the eyelets.
  10. The rod should be protected from particle blasting.
  11. Please contact us when Gas Springs have to be working in corrosive environment or outside with the rod in extended position.
  12. Make sure to avoid pollution of the rod surface by glue, putty, adhesives, corrosive products, paint, etc…
  13. When the cylinder has to be repainted, be careful to protect the rod (solvents should not be used to clean the rod in order to avoid damaging the seal).
  14. Protect the rod from blows, shocks, sparks from electric or grinding machines.
  15. Never grip the rod with pliers or in a vice without using efficient protective lead, aluminum or copper jaws.
  16. Be careful to heating effect of infrared devices (80°C máximum allowed temperature).
  17. Operating temperature range : from -30°G to + 80°C Endurance behavior based on 60.000 working cycles test: 15% máximum performance loss. (test actual results will vary according to stroke length and nominal force value).
  18. Nominal data are given for 20°G reference temperature. For each step of3°C, forces variation might be 1%. Check “temperature Vs F1” in “downloads”
  19. The self-contained gas (Nitrogen) is a neutral component of the atmosphere. Consequently, gas release is totally safe.
  20. The Gas Spring other components, except the oil, are mainly steel so recycling of these components is similar to steel recycling.
  21. To avoid pollution, used oil should be collected according to specific industrial waste regulations of each country.
