I do not have the specific parameter for this. Could not dig up a manual nor a ETS for this machine. So here it is from memory since this is a antique.
If you have the parameter, I would move the head to the tool change height, turn off the air and bleed off the pressure to allow the tool changer to move forward by hand, go to MOD and find CODE, type in 95148, ENT, this will get you into the parameters.
Change the tool change height parameter by what you need to have the tool changer slide onto a tool in the spindle.
