Its a model k2 btw

i have a kuhn reiter 55 kg powerhammer, that have a few problems:

when i turn it on, the ram doesn't go up for about 20 min, on a cold day it takes up to an hour.

when forging the ram doesn't go all the way up, and takes a few minutes before it goes up again after i stop forging, witch means i only get full power on the first blow.

but i can push the ram up with my hands. 

there are a few air leaks, that might be the cause of the problem, but i don't know.

hopefully someone here can help me
