2. Remove the hexagon socket head plug PT1/8 from the grease inlet and install the
grease zerk PT1/8. (The grease zerk is delivered with the manipulator.)
3. Inject grease from the grease inlet using a grease gun.
4. Move the S-axis for a few minutes to discharge excess grease.
5. Wipe the discharged grease with a cloth, and remove the grease zerk from the grease
inlet. Reinstall the plug PT1/8 on the grease inlet and the grease exhaust port. Apply
Three Bond 1206C to the thread part of the plugs, and tighten each plug with a tighten-
ing torque of 4.9 N·m (0.5 kgf·m).

Grease Exchange (Refer to "Fig. 22 S-axis Speed Reducer")
1. Remove the hexagon socket head plug PT1/8 from the grease exhaust port.
2. Remove the hexagon socket head plug PT1/8 from the grease inlet and install the
grease zerk PT1/8. (The grease zerk is delivered with the manipulator.)
3. Inject grease into the grease inlet using a grease gun.
4. The grease exchange is completed when new grease appears in the exhaust port.
The new grease can be distinguished from the old grease by color.
5. Move the S-axis for a few minutes to discharge excess grease.
6. Wipe the discharged grease with a cloth, and remove the grease zerk from the grease
inlet. Reinstall the plug PT1/8 on the grease inlet and the grease exhaust port. Apply
Three Bond 1206C to the thread part of the plugs, and tighten each plug with a tighten-
ing torque of 4.9 N·m (0.5 kgf·m).
Grease type: VIGO Grease RE No. 0
Amount of grease: 350 cc
(700 cc for first supply)
Air supply pressure of grease pump: 0.3 MPa or less
Grease injection rate: 8 g/s or less
• If grease is injected with the plug on, the grease will go inside the motor and may cause a
damage. Make sure to remove the plug before the grease injection.
• Do not install a joint, a hose, etc. to the grease exhaust port. Failure to observe this
instruction may result in damage to the motor due to coming off of an oil seal.
Grease type: VIGO Grease RE No. 0
Amount of grease: approx. 2300 cc
Air supply pressure of grease pump: 0.3 MPa or less
