NOTE
• If grease is injected with the plug on, the 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.
