(Refer to Fig. 4-1 "S-Axis Speed Reducer Diagram".)
Replenish the grease in accordance with the following procedure:
1. Remove the hexagon socket head cap screw M6 from the grease inlet
and the hexagon socket head plug PT1/8 from the exhaust port.
• If grease is injected with the screw on, the grease will leak
inside the motor and may cause a damage. Make sure to
remove the screw 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.
