(Refer to Fig. 9-4 "S-Axis Speed Reducer and Gear Diagram".)
1. Remove the hexagon socket head plugs from the grease inlet and
grease exhaust port.
• If grease is injected with the plug on, grease will leak
inside the motor and may cause a damage. Make sure to
remove the plug before the grease injection.
NOTE
• 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.
2. Install a grease zerk A-PT1/4 to the grease inlet. 
(The grease zerk is delivered with the manipulator.)
3. Inject grease through the grease inlet using a grease gun
– Grease type:
– Amount of grease:

4. Move the S-axis for a few minutes to discharge excess grease.
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 24.5 N•m 
(2.5 kgf•m).
