ive just set up my marcy home gym and i have a problem with working it.im sure its set up correctly non of the the handles etc will lift up the weights unless i unscrew the bolt/wire from underneath the weights.its what pulls the weights back down and the wire is connected to the powerbooster part.the power booster has a long piston called an air shock which i would have thought moved in and out but i cant move it.is this part faulty?here is a pic of the gym
does anyone have this gym or similar one who could help me
