tightened to the required torque (see
“Adjust the position of a J1-style crosshead” ).
• When the frame is equipped with a J3-style crosshead, be sure that the crosshead support collars
are positioned on the columns so they are in contact with the bottom of the crosshead and they
are tightened to the required torque (see
“Adjust the position of a J3-style crosshead” .
