Safety Data Sheet and Installation Instructions for Gas Struts

  IMPORTANT SAFETY INFORMATION

•  Please read these instructions carefully before you install this product
• Incorrect installation may invalidate product warranty
• Gas Struts (also known as Gas Springs)
• Gas Springs contain Nitrogen gas at high pressure
• Please dispose of used items carefully

Instructions for Installation

Gas struts should be mounted at an angle of 60° to the vertical with the piston rod down to ensure lubrication of the cylinder seals. The gas springs should be mounted without lateral forces. End fittings must be fully screwed into position on both ends prior to final location.

Gas struts contain nitrogen under high pressure. The cylinder should never be opened, punctured or exposed to high temperatures. Handle the piston rod with great care, as damage will result in consequential damage to the internal seals. The piston rod should not be scratched, soiled, painted, lubricated or bent. Damage to the piston rod will void the warranty

All gas struts have a seal between piston rod and cylinder. This seal is wetted with internal oil to ensure optimum functioning of the system. For this reason, gas struts should be installed with the piston rod pointing downwards.

Take great care when assembling and disassembling the gas pressure strut, as the pressure in the cylinder can generate dangerous forces.

Gas struts are not designed for transverse or lateral forces. If possible, use ball fasteners. To avoid bending the gas spring, the application should take the proportions of the cylinder into consideration.

Only 90% of the complete stroke should be used in order not to move the quantities of grease and oil at the end of the stroke again and again.

Ensure that the end fittings are fully fastened. If it is necessary to align the fastenings, the greatest care and attention should be taken.

Gas struts should not be used for more than 15 strokes/minute, otherwise disproportionately high heat generation due to friction will destroy the internal seals. We recommend using mechanical stops to limit the stroke of the cylinder.

Varilift® GAS StrutS

Varilift® gas struts contain nitrogen under high pressure. Never open, puncture or expose the cylinder to high temperatures. The Varilift® gas struts lose power in the long term. You should check periodically whether the desired function is still guaranteed. Otherwise, the gas pressure strut must be replaced.

INSTRUCTIONS to set the Varilift® VALVE

The Varilift gas strut® is fitted with a release valve (A) at the body end of the unit. This valve can be used to release gas from the unit to lower the force required to compress or extend it. Prior to attempting to perform this gas release, extreme care should be taken to prevent injury if too much gas is released. Where possible, it may be advantageous to increase the panel weight by 10% when performing this operation to prevent over release of the gas. To release gas from the unit use an allen key provided to unscrew the lock screw (B) at the side on the valve. Slowly unscrew the lock screw (anti-clockwise) until the gas can be heard escaping. Immediately re-lock the screw and try the unit. Extreme care should be taken during this operation as a small amount of discharge dramatically lowers the pressure of the unit. When using 2 struts on an application, adjust struts in sequence until the correct operation is achieved.

 Do not under any circumstances remove the adjustment screw from the valve.
