Notes on Grease Replenishment and Exchange Procedures
Make sure to follow the instructions listed below at grease replenishment
or exchange. Failure to observe the following notes may result in damage
to the motor or speed reducer.
• If grease is added without removing the plug or screw from
grease exhaust port, 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.
• Do not install a joint, a hose, etc. to the grease exhaust
port. Failure to observe this instruction may result in
NOTE
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.
