Useful Information

1.Gas springs are filled with high pressure Nitrogen and should not be repaired by non trained people.

Never try to open a gas spring if you haven’t received a specific training.

2. Never grind or weld near a gas spring.

3. Never modify nor machine a gas spring.

4. Never strike two gas springs rods against each other (the slightest mark on the piston rod may lead to a loss of pressure in the spring)

5. Never fill gas springs with a pressure higher than indicated on the body.

6. Never use a gas spring for other function than according to the catalogue.

7.Never fill a gas spring with other gas than nitrogen. Using other type of gas could result in personnaldanger

8.Operating temperature : 0 to 70°C.

9.Gas springs will permit travel of the full nominal stroke; however, a 10% stroke reserve is recommended to achieve optimal performance and safety.

10.Avoid side loading when possible. A misaligned press or die can cause side loading that increases wear on the bearing, seal and piston rod.

11.Protect gas springs by providing adequate drainage in gas spring pockets. Direct contact with certain die lubricants and cleaners should be avoided.

12.The end of the piston rod has construction thread intended for assembly and disassembly only.

Never to be used to mount or secure the gas spring. Die vibration and/or misalignment will damage the spring.

13.Never fill a gas spring when the rod is not fully extended.

Thread the T-handle 082078/000 (M8) or (M6) into the rod end and depress the valve stem with the Valve Bleed Tool, then pull the guiding ring up until it is seated firmly against the retaining ring.
