INSTRUCTIONS REGARDING DISPOSAL OF USED GAS SPRINGS

Handling gas springs
  • Gas springs are under high pressure. They must not be opened - not be heated.
  • Gas springs are filled with oil. Waste disposal only through raw materials trade or special refuse points.
  • Do not dispose of gas springs in household refuse. Oil must not get into soil or water.
Notes on waste removal in special workshops
The following work must be performed in compliance with the accident prevention and environment protection regulations:
a) Clamp gas spring in a vice.
b) Drill open units at the specified point with an approximately 3 mm thick drill bit to allow the gas to escape. Screen off the drilling point to prevent splashes of oil, swarf and nitrogen. Wear eye protectors!
1. Non-lockable gas springs
Make hole about 20 mm away from the bottom of pressure tube as shown in Fig. 1.
2. Lockable gas springs
Operate valve pin at piston rod end and allow the piston rod to extend fully. Drill a hole as shown in Fig. 2 at the end of the cylinder at the piston rod end. Then, drill a second hole about 20 mm away from the bottom of the cylinder. Then, once again press in valve at the piston rod end and push in piston rod.
c) The oil is drained from the gas spring by pumping the piston rod in and out several times.
d) Collect the oil and dispose of as specified by the relevant waste disposal regulations.
e) Gas spring oil is hydraulic oil and can be disposed of with motor oil/transmission lubricant according to the waste disposal law.
