Technical Advice: The valve head must be cleaned of dirt before applying grease. Introducing solid contaminants inside leads to the sealing ball getting blocked and a pressure drop in the system. Removing the valve to loosen the track requires slow unscrewing, which allows for a controlled release of the pressurized grease.
