2. Install a grease zerk A-PT1/8 to the grease inlet.
(The grease zerk is delivered with the manipulator.)
3. Inject grease through the grease inlet using a grease gun.
– Grease type: Molywhite RE No.00
– Amount of grease: approx. 1800 cc
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less

• If grease is injected with the plug on, grease will leak
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.
