6ml dropper bottle of food safe machine lubricant oil specifically for lubrication of espresso machine lever pins and group lever bearings. We have been seeing more and more machines with worn lever pins and an occasional micro drop of lubricant (use sparingly - it doesn't take much!) on the lever pins where they meet the lever yoke will save some expense and possible yoke or group boss damage down the line.
The product is "KASCO LUBRICOAT" food equipment oil , it will not spoil or become rancid as olive or other vegetable oils. Specifically designed for use in industrial food processing environments, USDA approved, this is the right lube for the exterior bearing surfaces on any lever machine....keep with the Dow 111 on the cylinder and piston as well as other internal seals but a touch of OE Lever Pin Lube will increase the longevity of your lever pins and possibly your group and therefore your machine!
