Few months back I purchased a second hand tripod.
Later on I noticed that the head (which holds the camera) of the tripod doesn't move freely.
I mean I have to apply some pressure to make it move left and right, and even when it moves left/right it jumps some fixed x degrees, i.e I can't make it move x+1 degree, it moves straightaway to x+5 degrees.
I don't know whether this is normal or not, but this is very annoying.
Is there a way that I can fix it? Perhaps by oiling at some right spots?
