Arm Top Cover
Unscrew the arm bottom cover mounting bolts and then remove the cover.
Be careful of the end effector. When the end effector is installed, the arm bottom cover
may not be removed from the shaft.
When you replace the ball screw spline unit, you need to remove the end effector to
remove the arm bottom cover completely.
When you can work (maintenance, inspection) without removing the cover completely,
move the shaft to the lower limit and lower the arm bottom cover.
For tightening hexagon socket head cap bolts, refer to “2.4 Tightening Hexagon Socket
Head Cap Bolts”.
