The manufacturer recommends lubricating the gearbox gears every 15-20 engine hours of trimmer operation. Lubrication must be carried out with special oils designed for high speeds and high temperatures, I use CV joints-4 for these purposes. Before applying grease, it is necessary to remove the gearbox from the rod for better filling of the cavities inside the gearbox. Also, in addition to the gearbox, it is necessary to lubricate the shaft inside the scythe rod to reduce its friction against the guide bushings. The upper gearbox of the brush cutter does not require lubrication. How, with what and how often to lubricate the gearbox is detailed in this video. #brushcutter #petrolcutter #gearbox #lubrication #maintenance #usefulathome
