Replenish the grease in accordance with the following procedure:
1. Remove the hexagon socket head plugs PT1/8 from the grease inlet
and from the exhaust port.

inside the motor and may cause a damage. Make sure to
remove the plug before the grease injection.

port. Failure to observe this instruction may result in
damage to the motor due to coming off of an oil seal.

packed with the manipulator on the shipment.)
