10.2 Maintenance for Manipulator
1. Before injecting grease, the posture of the manipulator must be set as
indicated in Table 10-3 "Recommended Posture for Grease Injection".
If it is difficult to make the recommended posture because of external
cabling or etc., adjust the posture as much as possible to make the
position of grease inlet located in the lower part and the position of
exhaust port located in the upper part. If the exhaust port is located in
the lower part, grease may not be exchanged properly.
