You will need to locate or make two (2) locking bars for the counter balance. There are two (2) holes in the column casting. Jog the Z-Axis slowly while another person installs the locking bars thru the holes in the casting and the counter balance. I then jog the table near the back of the machine and centered in the X-Axis. If you do not have the original 'fixture' for locking the Z-Axis to the table you can use a 4x4 piece of wood about 8" to 12" long. Slowly jog the Z-Axis down to the wood or the locking 'fixture'. Be sure not to rest the Z-Axis on the spindle nose. I usually rest the Z-Axis near the bolt hole for the 'fixture' if I use the wood block method.
The above is over and above removing the obvious items such as power, air, coolant tank, etc.
