| • Always use protective jaws when clamping the spring in a vice. • To achieve maximum service life, keep the gas spring protected from dirt, drawing, fluids and grinding dust. • Only specially trained personnel with good knowledge of the products should carry out the maintenance. Disassembling 1. To obtain an easy working position, clamp the spring in a vice (use protective jaws). Clamp the gas spring in a leaning position (about 30o) with the piston rod upwards for all models. This is to prevent oil from leaking out during the servicing. 2. Unscrew the M6 cover screw from the piston rod (G), using a 3 mm Allen key. 3. Discharge the gas in the spring. Thread the valve tool* into the charge port to open the valve. A Warning! The valve (H) must not be unscrewed until the piston rod can be pushed down by hand or with a rubber mallet. Once the gas is released use the opposite end of the valve tool* to unscrew the valve. Pull the valve from the port using the needle-nose pliers*. 4. Tap the guide (D) into the tube, using a mounting sleeve* and rubber mallet, until the lock ring (C) is exposed. Remove the dirt protection ring (B) which becomes loose during the procedure. 5. Remove the lock ring (C), using the lock ring tool*. A Warning! The lock ring could fly out, be sure to wear safety goggles. 6. Pull out the piston rod (A) and the guide (D), using a T-handle*. 7. Remove the guide (D) from the piston rod by pulling the guide upwards. 8. Save the piston rod (A) and the tube (E) | ||||||||||||||||||||||||||

| • Failure to exhaust all gas pressure prior to disassembling could result in serious injury. • Maximum charging pressure is 150 bar (2175 psi). • Use only pure nitrogen gas, N2 for charging. • Once the cover screw is removed from the piston rod, never lean directly over the valve. Always direct the valve port away from yourself and others. | ||||||||||||||||||||||||||
