Instruction For Use
  • Do mount standard gas springs rod down, use within a temperature range of –25°C up to +60°C.
  • Do not allow external objects to exert side load forces on the gas spring or on the end fittings.
  • Do ensure that the end fittings are in line so that side load forces are not applied as a result of misalignment.
  • Do try to use ball joints to help avoid side load forces. If eye (clevises) are used ensure a sloppy fit to allow lateral movement.
  • Do try to use shorter springs close to the hinge rather than long stroke springs away from the hinge.
  • Do provide physical stops to limit the spring’s extremes. i.e. ensure that undue force is not applied to over compress or over extend the spring.
  • Ensure the gas spring’s end fittings are compatible to gas spring and fully screwed home.
  • Do not cycle more than 15 times per minute. Do not scratch, dent, chip, bend or paint the rod.
  • If springs are to be stored prior to use, the spring should be stored rod down to lubricate the seal by its own.
