This section is for hydraulic vises with 2 mounting bollts.
Set the C-axis to its home position.
Clean the mating surface inside the center bore and on the spud of the hydraulic vice for chips and left over oil. Make sure the screws and washers are removed as well
To install the vise  carefully place the vise into the bore, make sure to align the hydraulic holes  inside the bore with the hydraulic holes on the vise . Be sure that the O-rings  are in the grooves of the hydraulic holes, if they are ripped or damage, replace them immediately
NOTE: The coupler on the platter can only be installed in one orientation. The hydraulic holes  can only be oriented in one way, be sure to match the holes on the coupler to those on the spud.
Use the SHCS and washer  to bolt the vise to the T-nuts  in the slot shown in the image.
While placing the vise make sure the DOWELS  are in the T-slots positioned above the left T-nut and under the right T-nut. They should sit diagonally across from each other.
NOTE: Always clean inside the center bore for chips before installing the hydraulic vise.
