Notes on Grease Replenishment/Exchange
Procedures
Make sure to follow the instructions listed below at grease replenishment/exchange. Failure
to observe the following notes may result in damage to motor and speed reducer.

Grease Replenishment/Exchange for S-axis Speed

Grease Replenishment (Refer to "Fig. 22 S-axis Speed Reducer")
1. Remove the hexagon socket head plug PT1/8 from the grease exhaust port.
• If grease is added without removing the plug/screw from the grease exhaust port, the
grease will go inside a motor or an oil seal of a speed reducer will come off, which may
result in damage to the motor. Make sure to remove the plug.
• 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.
• Make sure to use a grease pump to inject grease. Set air supply pressure to the grease
pump at 0.3 MPa or less, and the grease injection rate at 8 g/s or less.
• Make sure to fill the hose on the grease inlet with grease beforehand to prevent air from
leaking into the speed reducer.
• 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.
