------------------------------------------------------------------------
AUTOMATIC OPENING depends of power gas springs (useing /Permanent/ and cool temperatures /Temporary/ reduces their power), about 1/3 opening power to do SPECIAL SPRINGS and the remaining 2/3 to do GAS SPRINGS. Maybe you need new gas springs.
------------------------------------------------------------------------

Installation instructions:
Gas springs should be removed (screwdriver).
--- WARNING - door before you unlock Gas springs secure against falling. ---
Plastic end must be removed, the gas spring rod is necessary to hold with pliers and a plastic end with pliers turn left (classic thread), springs pushed onto gas springs and put everything in the reverse steps to the original state. That's all :)
