Make sure to fix the nitrogen gas spring by the base screw aperture or suitable mount parts. If not, it will reduce the service life or to damage the nitrogen gas spring.
Make sure the top of the piston rod to touch the surface of the mold completely. Refuse to lengthen the piston rod by joining for use. If not, it will reduce the service life or to damage the nitrogen gas spring.
The nitrogen gas spring cannot withstand any leaning force. If not, it will reduce the service life or to damage the nitrogen gas spring.
Make sure the nitrogen gas spring’s piston has the parallel moving direction when it is compressed and keep the piston rod being at the free motion condition. If not, it will reduce the service life or to damage the nitrogen gas spring.
In order to make sure the trouble-free work, suggest keeping the 10% or 3mm of traveling length not to be used.
Make sure not to surpass the biggest charging pressure under 20℃. If not, it will have the unsafe hidden danger.
The operating temperature of the nitrogen gas springs is from 0℃ to +80℃. If it’s over 80℃ when it’s working, the cooling way should been taken. When it’s cooled to under 80℃, then it can be used continuously. If not, it will reduce the service life or to damage the nitrogen gas spring.
The biggest movement frequency of the nitrogen gas spring is 2/sec. If surpass this frequency, it will reduce the service life largely.
To use liquid lubricant on the piston rod is not allowed. If used, the nitrogen gas spring maybe crack when it’s working. You could brush a few of the fat lubricant when to use the nitrogen gas spring first time.
When the velocity of the piston rod is smaller than 800 mm/sec. and the working frequency of the piston rod is under 2 times /sec., the life time of running length of the piston rod is over 100 kilometer.
Any person hasn’t trained or without the knowledge of the springs doesn’t open and maintain the nitrogen gas springs It will cause the personal safety question if open the nitrogen gas spring at random.
Keep the piston rod of the charged nitrogen spring not to face to the operators when transporting, installing and servicing. It can prevent the accidental personal safety problem.
The lubricant used in the nitrogen gas spring’s cavity and the fat lubricant used on the piston rod must be provided by our company. If not, it will have the unsafe hidden danger.
The surface of the piston rod was processed by the precision sizing and special surface treatment. You should avoid the piston rod’s surface to meet the impacts and scratches when transporting and using. If not, it will shorten its life time and will be damaged.
The service life is bigger than 1,000,000 times under the normal work condition.
When the nitrogen gas spring will be idle for a long time, the surface must be spreaded the rust-preventing agent for against corrosion.

“ In order to achieve the most satisfactory effect in use and to use safely for the nitrogen gas springs, please carry out without fail the “Attention in usage”. Our company can provide the essential service consultation for you
