Super Cut MF is a specially formulated mineral oil designed to lubricate the cutting chain, cutter bar and drive gear on Industrial and Light duty Chain Saws. It contains heavy metal free anti wear and adhesive additives to ensure that adequate lubricant adheres to the rubbing surfaces. In these all loss systems the lubricant is expelled into the environment and heavy metals such as zinc get absorbed by growing plants and thus get into the food chain. Super Cut MF does not contain any of these potentially harmful compounds. It inherently flows easier providing instant lubrication on start-up and less load and wear on the oil pump.
