1. Remove the hexagon socket head plugs PT1/8 from the grease inlet
and from the exhaust port.
2. Install the grease zerk A-PT1/8 to the grease inlet. (The grease zerk is

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.
NOTE
The exhaust port is used for air exhaust, and the grease is
not exhausted from the exhaust port. Do not inject
excessive grease through the grease inlet.
