SmörjnippelrensarenOpens clogged lubrication points. Sometimes when you try to lubricate the lubrication point will not grease through grease fitting, since many believe that this is a stupid grease nipple again, sometimes it's so. Often the problem is that fat has "solidified" the lubrication point. By using this product, you can force the light oil into the lubrication point, which dissolves the old, hard fat and allows new grease to get into. Fill the cleaner with thin oil type hydralolja and press it against lubricant instead and hit with a hammer on the end DONE!
