About my PG-02 gimbal, RRS states: "The PG‐02 is lubricated at the factory and parts that require lubrication are sealed. NO LUBRICATION IS REQUIRED BY THE USER. Just keep the components free from contamination to maintain smooth action."
Due to unexpected production delays, this item will be back-ordered until after May 1st, 2014.
