9.3 Notes on Grease Replenishment/Exchange Procedures
5. Wipe the discharged grease with a cloth, and reinstall the plug. Before
installing the plug, apply Three Bond 1206C on the thread part of the
plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
6. Remove the grease zerk from the grease inlet, and reinstall the plug
Before inst
alling the plug, apply Three Bond 1206C on the thread part
of the plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
9.3.4.5 Grease Exchange for R-, B-, T-Axes Gears in the Casing
(Refe
r to Fig. 9-7 “U-Arm Diagram”.)
1. Remove the hexagon socket head plug PT1/8 from the grease
exhaust port.
2. Install a grease zerk A-PT1/8 to the grease inlet. (The grease zerk is
d
elivered with the manipulator.)
3. Inject the grease through the grease inlet using a grease gun
– Grease type: Molywhite RE No. 00
–
Amount of grease: approx. 2000 cc
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
4. The grease exchange is completed when new grease appears in the
gr
ease exhaust port. (The new grease can be distinguished from the
old grease by color.)
5. Move the R-, B-, T-Axes for a few minutes to discharge excess grease.
6. Wipe the discharged grease with a cloth, and reinstall the plug. Before
inst
alling the plug, apply Three Bond 1206C on the thread part of the
plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
7. Remove the grease zerk from the grease inlet, and reinstall the plug.

9.3.4.6 Grease Exchange for R-Axis Speed Reducer
(Refe
r to Fig. 9-7 “U-Arm Diagram”.)
1. Remove the hexagon socket head plug PT1/8 from the grease
exhaust port.
2. Install a grease zerk A-PT1/8 to the grease inlet. (The grease zerk is
d
elivered with the manipulator.)
If grease is injected with the plug on, the grease will leak
inside the motor and may cause a damage. Make sure to
remove the plug before the grease injection.
