Atlas Copco Cobra & Compactor Impact-Oil is a premium mineral oil for optimal performance and protection of the transmission and impact mechanism in Cobra breakers. Each oil bath has a capacity of 100 ml/3.4 US fl oz. They are checked periodically and refilled when the oil level drops, and they are replaced when a general overhaul is required, which is at least once a year.
