9.6 Axis motors
For the all axis motors, there are holes for grease-leakage detection. Remove the screws
from the holes to check for grease leaking from the motor. For these procedures of each
axis, refer to figure “Positions of grease-leakage detection hole".
When grease leakage is detected, contact YASKAWA representative.
For the “ * ”parts, the screw whose head faces to the ground must be removed to check the
hole.
Move the robot to make the either one of screws marked with “*” face to the ground and
remove it to check the hole.
