<Do not take a nut off><Do not let a nut overrun>QNotesEFilled with lithium soap based grease (Alvania Grease S2 made by Showa Shell Sekiyu K.K).EFor accuracy of Ball Screws, see P.2223 and P.2224.EFor details of Support Units, see P.753 ~ P.778.ECautions: Do not let the nuts overrun or remove the nuts from the screw shafts.

It may cause the balls to fall out or damage the ball recirculation parts.E�Do not tilt the ball screw assembly since the nut may spin off from the shaft due to its own

weight.EUse one of the support unit accessory collars on the fastening nut side.
