My SCA was (cheapo) takes a lot of pumping to get up. Doesn't clear any slammed car (had to drive onto some wooden planks before I could jack it up, then lower it down onto them again) and is also really quite heavy.
Sounds like either the oil (shocky oil, not atf) is low (remove the metal plate and unscrew or unplug if rubber bung, the filler. Oil should be just below the hole with the jack lowered) or it's got air trapped. Pump it up and release with a bit of pressure applied to the end of the arm a few times. None of these sorts of jacks will get under a lowered car, have seen aluminium "racing" types advertised that have a slim roller at the front instead of wheels and a low jacking pad. I have to get mine up on 2" blocks to get my jack under. Dreading getting a flat tyre and the "pumpup" stuff not working.
