OM603 how much timing adjustment does it have?

Mine is advanced full retard by the previous owner. It seems to run fine without any nailing and plenty of power. Just curious how many degrees of movement I have before I start messing with it. At first I thought the timing chain might be stretched hence the pump being fully advanced but its not. There is zero degrees of stretch between the crank and cam at 194k miles.
thanks

Does anybody know how many degrees of rotation are built into the 3 timing slots on the injection pump?
