9.3.1 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.
• If grease is added without removing the plug/screw from
the grease exhaust port, the grease will leak 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/screw.
• 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.
