Grease Replenishment/Exchange
Make sure to follow the instructions listed below at grease replenishment/
exchange. Failure to observe the following notes may result in damage to
a motor and a speed reducer.
• If grease is added without removing the plug/screw from
the 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/screw.
• 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 hoses, which are joined to the grease
inlet, with grease beforehand to prevent air from intruding
into the speed reducer.
