While tilting the head in the x or y direction can be very handy the machine does not have a controlled way of adjusting for tramming. In the x directing it is very well balanced with a slight bias to the rear so I use a short 3/8" bolt and nut between the casting and the transmission housing when tramming using the nut for fine adjustment. In the y direction it is massively biased to the right and if released with the safety pin removed will rotate 90 degrees in a hurry. I use a long 3/4" bolt between the base and the head with a bit of aluminum tube sitting on the nut and washer, again turning the nut provides fine adjustment. I have taken to leaving the long bolt in place parking the head on it when not in use.
